Window Replacement Chicago, Illinois: Cold-Climate Precision for the City That Invented the Polar Vortex

Chicago weather is not a cliche. It is a performance test that runs every single year. January wind chills that drop below minus 30 degrees. Summer heat indexes above 100. Lake-effect moisture events that infiltrate poorly installed window frames. Freeze-thaw cycles that do to window seals what the El does to asphalt. The City of Chicago has its own building code, its own Express Permit Program for window replacement, and its own contractor registration requirement for Cook County. If your window replacement company does not know those requirements, your project is starting behind.

Virtual View Windows delivers professional window replacement for Chicago homeowners, condo owners, and two-flat owners who understand that this city demands a higher standard of product specification and installation precision than most markets. We install cold-climate-rated windows with U-factors of 0.27 or below, as HomeBuild Windows’ Chicago market analysis identifies as the performance target for this climate. We handle Chicago’s Express Permit Program on your behalf. We document ComEd and Illinois program qualifications for every applicable project.

From Wicker Park and Logan Square to Lincoln Park and Lakeview, from Evanston and Oak Park to Naperville and the western suburbs, we are the window replacement near you that Chicagoland homeowners trust for cold-climate precision backed by a lifetime warranty and no payment until every window passes your inspection.

How Virtual View Windows Handles Every Chicago Window Replacement

Our Chicago process is built around the city-specific compliance, housing type, and cold-climate requirements that make window replacement in Chicago more complex than in most other markets.

Step 2: Chicago Landmarks Commission Pre-Consultation (Where Applicable)

For properties with Chicago Landmark designation or within a Chicago Landmark district, we initiate the Commission on Chicago Landmarks pre-consultation process before placing your window order. We review the applicable Landmark district design guidelines, identify COA-compliant products, and assist with the Certificate of Appropriateness application. Installation does not proceed until the COA is issued.

Step 4: Installation Day

Our Illinois-licensed installation crew arrives with all tools, cold-climate flashing materials, winter-grade exterior sealants, and trim supplies. We remove existing windows, inspect each rough opening for moisture damage, deteriorated weatherstripping, or structural concerns common in Chicago's older housing stock, and install your new windows to manufacturer specifications and Chicago Energy Transformation Code air-sealing requirements. Most Chicago single-family projects of 10 to 15 windows are completed in one day.

Window Replacement Styles for Chicago Homes

Chicago’s architectural range spans every American residential style from Victorian graystone to Prairie Style, from Chicago bungalow to mid-century high-rise. Virtual View Windows installs every major replacement window style, custom-ordered to your exact rough opening dimensions.

Double-Hung Window

Chicago’s dominant residential window replacement style across virtually every housing type. Both sashes tilt inward for interior cleaning, which is particularly practical in Chicago’s attached graystone and two-flat housing stock where exterior window access requires working at height on a city lot with minimal setback. Angi documents the average double hung window at $800 in Chicago. HomeBuild Windows confirms basic vinyl double hung at $400 to $600 installed.

Casement Windows

Crank-operated and side-hinged, casement windows create a compression seal that provides superior resistance to the air infiltration that Chicago’s sustained winter wind events drive through inferior window installations. Particularly effective in Chicago’s craftsman bungalows and the Arts and Crafts homes across Oak Park, River Forest, and Beverly. When open, casement windows capture the summer lake breezes that make Chicago livable from May through September.

Sliding Windows

Horizontal-operating sashes suit the ranch-style homes across Chicago’s South Side and southwest suburban communities. A clean contemporary look appropriate for newer construction and modern remodels. Available in vinyl with U-factor and SHGC specifications meeting Chicago Energy Transformation Code requirements.

Picture Windows

Fixed-frame non-operable windows maximize natural light and views without air leakage. In Chicago’s higher-density neighborhoods, picture windows in living rooms and dining rooms provide light wells that are particularly valuable in the narrower lot configurations of Chicago’s attached housing stock. Zero air infiltration makes them the most energy-efficient style for any opening, which is significant in a market where the U.S. Department of Energy documents 25 to 30 percent of heating energy escaping through inefficient windows.

Bay and Bow Windows

Chicago’s Victorian greystone and Queen Anne homes contain bay window projections that are architecturally defining features of entire streetscapes. Bay window replacement in Chicago requires careful attention to the projecting roof plane flashing that prevents moisture infiltration during Chicago’s lake-driven rain and sleet events. Bow windows across four to six units are popular in Chicago’s craftsman and colonial suburban homes in Evanston, Wilmette, and Winnetka.

Awning Windows

Awning windows are top-hinged and open outward, providing ventilation during Chicago’s unpredictable spring and fall rain events. Hopper windows hinge at the bottom and are frequently used in Chicago’s finished basement conversions and garden-level apartments. Both styles are available in standard vinyl and fiberglass with Chicago code-compliant glass packages.

Noise-Reduction Windows for Chicago Urban Living

Chicago’s density means that many homeowners are choosing window replacement primarily for noise reduction from traffic, the El, and urban activity. Triple-pane glass with U-factors as low as 0.15 delivers meaningful noise reduction alongside superior thermal performance. For homes within a few blocks of a CTA rail line, Metra corridor, or a major Chicago arterial, triple-pane glass is a quality-of-life upgrade that pays dividends year-round, not just in winter heating bills.

What Chicago's Climate Actually Demands from Replacement Windows

Chicago is one of the most demanding cities in the continental United States for window replacement performance. The intersection of Lake Michigan’s open fetch, the Great Plains cold air corridor, and the urban density of Cook County creates a climate profile that subjects window installations to stresses that most window companies serving warmer or less windy markets have never encountered.

Polar Vortex Events and Extreme Cold

Chicago’s periodic Polar Vortex events bring temperatures below minus 20 degrees Fahrenheit to the city, with wind chills that can plunge below minus 50 degrees on the lakefront. For window replacement, these events test every thermal specification: the U-factor that determines how much heat escapes through the glass, the edge-seal performance that determines whether cold air infiltrates around the frame, and the frame material’s dimensional stability at temperatures that most inland cities never approach. HomeBuild Windows’ 2025 Chicago market analysis identifies a U-factor of 0.27 or lower as the ideal target for Chicago’s climate. This is not a luxury specification for the Chicago market. It is the performance threshold that separates comfortable homes from the ones with frost patterns on the interior glass during a January deep freeze.

Lake Michigan Wind and Moisture Events

Chicago’s lakefront exposure creates wind-driven moisture events that test window frame seals and weatherstripping differently than inland cold. When a northwest wind off the lake drives sleet or freezing rain horizontally across the city, windows on the north and west elevations of Chicago homes face conditions similar to those in Portland’s rainy season and Baltimore’s winter storms simultaneously. Proper exterior flashing, warm-edge spacer systems, and comprehensive rough opening air sealing are not optional specifications for Chicago window replacement. They are the baseline that prevents moisture infiltration and the accompanying interior damage that develops over years of inadequate installation.

Chicago's Diverse Housing Stock and Window Replacement Complexity

Chicago’s architectural diversity creates window replacement challenges that no single-market window company encounters elsewhere at this scale. Single-family bungalows in Beverly and Mount Greenwood. Vintage graystone two-flats throughout Wicker Park and Bucktown. Pre-war courtyard apartments on the North Side. High-rise condos in Streeterville and the Gold Coast. Craftsman and Prairie Style homes across Oak Park and River Forest. Each housing type presents different window replacement logistics, different product selection considerations, and in many cases, different permit and code requirements. A window replacement company that serves Chicago needs the range to handle all of these effectively.

Chicago Landmark and Historic Districts

Chicago’s Department of Planning and Development administers an active Chicago Landmark designation program that covers individual buildings and landmark districts across the city. Properties with Chicago Landmark designation are subject to the Commission on Chicago Landmarks review for exterior changes including window replacement. The Commission evaluates whether proposed replacement windows preserve the historic character of the designated resource. Virtual View Windows guides Chicago homeowners through the Landmarks Commission process for applicable properties and assists with product selection that satisfies both Landmarks review requirements and modern energy performance standards.

Chicago Building Permits, Contractor Registration, and Code Requirements

Chicago’s regulatory environment for window replacement has three layers that homeowners need to understand: the City of Chicago’s Express Permit Program, contractor registration requirements, and Chicago’s own energy code that applies to new window openings.

City of Chicago Express Permit Program

The City of Chicago’s Department of Buildings operates an Express Permit Program specifically designed for window replacement in existing wall openings. Replacing an exterior window in an existing wall opening with the same type of window in a building up to 7 stories tall qualifies for the Express Permit Program. Windows above 7 stories, windows in walls within 2 feet of a property line, and window installations that do not meet the minimum energy efficiency requirements of the Chicago Energy Transformation Code require a full permit and additional documentation.

The Express Permit Program requires that the contractor be a licensed general contractor (Class A, B, C, D, or E based on total project cost). Buildings with more than 3 stories replacing a window in a wall within 2 feet of a lot line that separates two properties have additional requirements including architectural or structural engineer drawings. Virtual View Windows handles the Express Permit Program application for every applicable Chicago project before installation begins.

Cook County Contractor Registration

Angi’s Chicago market research specifically documents that Cook County requires window contractors to be registered with the Cook County Department of Building and Zoning. A window replacement pro may also be required to hold a valid City of Chicago general contractor license. Angi advises Chicago homeowners to verify that their window contractor has the necessary licenses and certifications before signing any agreement. Virtual View Windows maintains all required Chicago and Cook County registrations and licenses. Ask any window replacement company you are evaluating for their Cook County registration number and City of Chicago contractor license before signing any contract.

Chicago Energy Transformation Code

Chicago has adopted the Chicago Energy Transformation Code, which aligns with the Illinois Energy Conservation Code and sets minimum energy efficiency requirements for windows. Specifically, installing a new window, door, or skylight that does not meet minimum energy efficiency requirements of the Chicago Energy Transformation Code requires a full permit rather than the streamlined Express Permit Program. This means that any window replacement in Chicago must meet the applicable energy performance thresholds to qualify for the Express Permit process. Virtual View Windows installs only products that meet Chicago Energy Transformation Code requirements, confirming code compliance before any product is ordered.

Chicago Landmarks Commission

For properties with Chicago Landmark designation or located within a Chicago Landmark district, exterior window replacement that alters the appearance visible from a public right of way requires a Certificate of Appropriateness from the Commission on Chicago Landmarks. The Commission reviews frame material, profile, configuration, and glazing pattern to ensure the proposed replacement preserves the historic character of the designated resource. Virtual View Windows guides Chicago Landmark homeowners through the COA application process and identifies window products that satisfy both Landmarks Commission requirements and Chicago energy code performance thresholds.

Window Replacement Across Chicago's Diverse Housing Types

Chicago’s housing stock is unlike any other city’s in this series. The same window replacement company needs to be equally competent in a Lincoln Park condo, a Wicker Park two-flat, a Beverly bungalow, and an Oak Park Prairie Style home. Here is how window replacement considerations differ across Chicago’s major housing types.

Housing Type	Window Replacement Context	Key Considerations
Single-Family Bungalow and Ranch	Most common type across Chicago’s working-class neighborhoods (Beverly, Mount Greenwood, Portage Park, Avondale). Typically 1 to 1.5 stories, 8 to 12 windows.	Express Permit Program typically applicable. Cook County contractor registration required. Standard vinyl or fiberglass frames appropriate. Energy code compliance straightforward.
Vintage Two-Flat and Greystone	Dominant housing type in Wicker Park, Logan Square, Bucktown, Pilsen. 2 stories, often 12 to 20+ windows. Angi notes Chicago home sizes range from under 1,000 sq ft condos to 3,300 sq ft suburban homes.	Both units typically owned separately or as rental property. Landlord-tenant coordination needed. Graystone facade may trigger Landmarks review in designated areas. Upper floor access may require staging.
Condo and High-Rise	Gold Coast, Streeterville, Lakeview, South Loop. Window replacement often governed by condo association architectural review board. Buildings over 7 stories require full permit, not Express Permit.	Condo association approval required before ordering. Buildings over 3 stories near lot lines need engineer drawings per Chicago code. Noise-reduction glass worthwhile for lakefront and urban locations.
Chicago Landmark or Historic District Property	Prairie Style homes in Oak Park and River Forest. Greystone two-flats in Landmark districts. Victorian homes in designated neighborhoods.	Certificate of Appropriateness required from Commission on Chicago Landmarks before ordering. Frame material, profile, and glazing pattern subject to COA review. Virtual View Windows guides the Landmarks process.

Window Replacement Cost in Chicago, Illinois

Window replacement in Chicago reflects the city’s union labor rates, cold-climate material requirements, and the complexity of Chicago’s diverse housing stock. Here are current benchmarks from multiple Chicago-specific sources.

Window Type and Material	Low (Installed)	High (Installed)
Basic vinyl double hung (installed)	$400	$600
Standard vinyl double hung (Chicago avg.)	$349	$480
Average single window, Chicago (all types)	$750	$1,200
Premium casement (vinyl or fiberglass)	$600	$1,000
Fiberglass double hung	$650	$1,200
Wood or wood-clad double hung	$600	$1,000
Landmark-compliant wood-clad (premium)	$900	$2,000+
Bay or Bow Window (Chicago graystone)	$1,200	$5,000+
Triple-Pane upgrade (noise + thermal)	+$150	+$500
Specialty / arched / non-standard shape	$600	$2,500+

Whole-Home Window Replacement Estimates for Chicago Homes

Angi specifically notes that Chicago home sizes range from under 1,000 square feet for a downtown condo with fewer than 10 windows to an average of 3,300 square feet for new suburban homes with potentially double or triple that window count. Here are estimates based on project scope:

Project Scope	Low Estimate	High Estimate
Downtown condo (under 10 windows, vinyl)	$2,766	$5,000
Chicago bungalow (10 windows, vinyl)	$3,490	$6,000
Two-flat (15 to 20 windows, vinyl)	$5,235	$9,191
Single-family home, average (Angi $5,943)	$5,943	$9,191
Suburban colonial (20+ windows, vinyl)	$7,000	$15,000+

Key Cost Factors for Chicago Window Replacement

U-factor performance: Chicago cold-climate requires 0.27 or below for optimal performance. Standard products meeting code minimum may cost less initially but perform less effectively during Polar Vortex events.

Housing type: Two-flats and taller buildings add per-window cost through staging and coordination requirements. Condos may require association approval coordination before ordering.

Landmark compliance: Properties requiring Chicago Landmarks Commission Certificate of Appropriateness need COA-compliant products that typically carry a premium over standard replacement materials.

Noise reduction: Triple-pane glass adds $150 to $500 per window over standard double-pane but delivers meaningful noise reduction for Chicago urban and near-transit locations.

Project size: Larger whole-home projects reduce per-window cost through labor efficiency.

Express Permit fees: Chicago’s Express Permit Program carries associated fees for applicable projects. Virtual View Windows handles the application.

ComEd, Illinois Programs, and Energy Incentives for Chicago Homeowners

Chicago homeowners have access to a set of financial incentive programs that reduce the effective cost of qualifying window replacement projects. Here is the current 2025 picture.

Illinois HOMES and HEAR Programs

Illinois is eligible to receive $263 million in federal funding through the Home Efficiency Rebates (HOMES) and High-Efficiency Electric Home Rebate Act (HEAR) programs under the Inflation Reduction Act, as documented by Illinois HVAC analysis.

The Investment Case: Energy Savings and ROI

HomeBuild Windows Chicago documents that upgrading from single-pane to ENERGY STAR-certified windows saves a typical Chicago homeowner $125 to $350 annually on energy bills. The 2024 Cost vs. Value Report by the Journal of Light Construction shows a 73.6 percent ROI for vinyl window replacement in Chicago and 73 percent for wood window replacement. Translated to dollar value, new windows added more than $14,000 to Chicago-area home resale values per HomeBuild’s 2025 analysis. Combined with Homeyou’s documentation of up to 40 percent energy cost savings replacing old Chicago windows, the investment case is compelling in this market.

Chicago homeowners replacing windows in 2025 or 2026: Check the Illinois HOMES and HEAR program status at the Illinois Energy Office before scheduling your project. If approved, these programs could significantly reduce your net project cost for qualifying window replacement with income-based rebates. Virtual View Windows provides all required documentation for applicable Illinois programs at project completion.

Why Chicago Homeowners Choose Virtual View Windows

Chicago has a competitive window replacement market, and not every company that advertises in the metro understands Chicago’s Express Permit Program, Cook County contractor registration requirements, or the cold-climate performance specifications that separate an excellent Chicago window installation from one that drafts by January of the following year.

Chicago and Cook County Compliance Expertise

Virtual View Windows maintains all required Chicago general contractor licenses and Cook County registrations. We handle the Express Permit Program application for qualifying window replacement projects before installation begins. We identify when a full permit is required and manage that process on your behalf. We install only Chicago Energy Transformation Code-compliant products on every city project.

Cold-Climate Specification for Polar Vortex Performance

We do not offer one-size-fits-all glass packages for Chicago window replacement. Every project leads with U-factor performance discussion, targeting 0.27 or below as the HomeBuild Windows market threshold for optimal Chicago climate performance. We specify warm-edge spacer systems that protect seal integrity through Chicago’s freeze-thaw cycles, argon gas fill standard on all double-pane units, and Low-E coatings tuned for the Northern zone’s mix of winter heating retention and summer solar management.

Two-Flat, Condo, and Landmark Property Experience

Virtual View Windows serves Chicago’s full range of housing types. We coordinate with condo association architectural review boards before placing window orders. We guide vintage two-flat owners through the upper-floor staging and coordination involved in replacing windows on both units. We navigate Chicago Landmarks Commission COA applications for designated properties. This multi-housing-type competence is not something a window company focused on suburban single-family homes can import into Chicago effectively.

Transparent Written Estimates Without High-Pressure Sales

Chicago homeowners have documented frustrations with window replacement companies that use high-pressure sales tactics, same-day decision demands, or multi-hour in-home presentations with prices that drop mysteriously if you agree tonight. Virtual View Windows provides accurate written estimates, often within one business day, without requiring an in-home sales appointment or same-day pressure. No payment until every window passes your personal inspection.

Lifetime Warranty for Chicago's Climate Extremes

Every Chicago window replacement project Virtual View Windows completes carries a lifetime warranty on both the installed product and our workmanship. Chicago’s Polar Vortex events, lake-driven moisture, and the freeze-thaw cycles of a five-month heating season test every window installation over time. Our warranty holds through those tests.

Window Frame Materials for Chicago's Cold Climate

Frame material selection for Chicago window replacement must account for the city’s extreme cold, freeze-thaw cycling, moisture events, and in some cases Chicago Landmarks Commission requirements for historic properties.

Vinyl: Chicago's Volume Standard

Premium vinyl dominates Chicago window replacement by volume. HomeBuild Windows’ 2025 Chicago analysis confirms that vinyl frames offer excellent value for Chicago homeowners when manufactured with quality UV inhibitors and proper thermal performance. Standard vinyl double hung windows installed in Chicago run $400 to $600 per HomeBuild’s data. Vinyl lifespan in Chicago’s climate is typically 20 to 40 years. Vinyl frames do not conduct cold the way aluminum does, never need painting, and maintain dimensional stability through Chicago’s freeze-thaw cycles reliably. For Chicago Landmark properties, vinyl is sometimes acceptable on rear or non-street-facing elevations where it is not visible from public rights of way.

Fiberglass: Best Cold-Climate Stability

Fiberglass frames expand and contract less than vinyl across Chicago’s temperature range from minus 20-degree Polar Vortex lows to 95-degree July heat. This dimensional stability is particularly valuable for Chicago’s freeze-thaw cycling, protecting seal integrity and hardware alignment across decades. Fiberglass accepts exterior paint, can meet Chicago Landmark profile requirements in approved colors, and outperforms vinyl in long-term cold-climate performance. Cost runs approximately $650 to $1,200 per window in Chicago. An excellent choice for any Chicago homeowner prioritizing longevity and cold-climate performance over initial cost.

Wood and Wood-Clad: Chicago's Historic Properties

Chicago’s Landmark Commission design guidelines for designated historic districts often require wood or wood-clad frame profiles on street-facing elevations to preserve the architectural character of the historic resource. Solid wood double hung windows are the historically appropriate replacement for Chicago’s graystone and Victorian era housing stock. Wood-clad windows with aluminum or fiberglass exterior shells eliminate the exterior maintenance burden while satisfying Landmark profile requirements. Cost runs $600 to $1,000 or more for standard double hung sizes. Virtual View Windows assists Chicago Landmark homeowners in identifying wood-clad products that satisfy both Landmarks Commission requirements and Chicago Energy Transformation Code performance standards.

Glass Package for Chicago's Northern Climate Zone

For Chicago’s Northern climate zone, here are the performance specifications that matter most:

U-Factor: 0.27 or below per HomeBuild Windows’ Chicago market recommendation for optimal performance. 0.30 required minimum for Chicago Energy Transformation Code compliance on new window openings.

Solar Heat Gain Coefficient: 0.25 to 0.35 balanced for Chicago’s significant winter passive solar benefit and summer cooling management.

Low-E Coating: Standard on all energy-efficient Chicago replacements. Reduces winter radiant heat loss and summer solar heat gain.

Argon Gas Fill: Standard between panes. Reduces conductive heat transfer at Chicago’s extreme temperature differentials.

Triple-Pane Glass: U-factor as low as 0.15. Recommended for Chicago homes near the El, Metra lines, or major arterials for combined thermal and noise performance. Particularly effective during Polar Vortex events.

Frequently Asked Questions About Window Replacement in Chicago, Illinois

How much does window replacement cost in Chicago, Illinois?

Window replacement in Chicago averages $750 per window and $5,943 for a total project per Angi’s July 2025 Chicago data, with a typical range of $2,766 to $9,191. Homeyou’s dataset from 1,275 completed Chicago-area projects shows the majority of homeowners paying $349 to $480 per window for a standard project cost of $4,982. SmardBuild Chicago documents $750 to $2,200 per window for the full range including complex projects. A basic vinyl double hung installed runs $400 to $600 per HomeBuild Windows’ 2025 analysis. Downtown condos with fewer than 10 windows typically cost $2,766 to $5,000. Larger suburban homes with 20-plus windows can run $7,000 to $15,000 or more. Virtual View Windows provides free written estimates with no payment until every window is installed and approved.

Do I need a permit for window replacement in Chicago?

Yes. Replacing an exterior window in Chicago requires a building permit through the City of Chicago Department of Buildings. However, standard like-for-like window replacements in buildings up to 7 stories typically qualify for Chicago’s Express Permit Program, which streamlines the process significantly. Windows that do not meet minimum Chicago Energy Transformation Code energy efficiency requirements cannot use the Express Permit Program and require a full permit. Buildings over 7 stories, windows within 2 feet of a lot line, and Chicago Landmark properties have additional requirements. Cook County also requires window contractors to be registered with the Cook County Department of Building and Zoning. Virtual View Windows handles the permit application for every Chicago project before installation begins.

What window specifications are best for Chicago's climate?

For Chicago’s Northern climate zone with Polar Vortex events and extreme cold, HomeBuild Windows’ 2025 Chicago market analysis identifies a U-factor of 0.27 or lower as the ideal target. Low-E coatings standard for winter heat retention and summer solar management. Argon gas fill between panes. The Chicago Energy Transformation Code requires minimum energy performance standards for all replacement windows. For Chicago homes near CTA rail lines, Metra corridors, or major arterials, triple-pane glass with U-factors as low as 0.15 adds meaningful noise reduction alongside superior thermal performance. Premium vinyl or fiberglass frames with these specifications deliver the performance Chicago winters demand.

Do Chicago Landmark properties have special window replacement requirements?

Yes. Properties with Chicago Landmark designation or within a Chicago Landmark district require a Certificate of Appropriateness from the Commission on Chicago Landmarks before exterior window replacement visible from a public right of way can proceed. The COA review evaluates frame material, profile, configuration, and glazing pattern to ensure the proposed replacement preserves the historic character of the designated resource. This requirement is separate from the standard Chicago building permit process. Landmark-compliant wood or wood-clad replacement windows typically cost more than standard vinyl products. Virtual View Windows guides Chicago Landmark homeowners through the COA application process and assists in identifying products that satisfy both Landmarks requirements and Chicago Energy Transformation Code performance standards.

What is the return on investment for window replacement in Chicago?

The 2024 Cost vs. Value Report from the Journal of Light Construction documents a 73.6 percent return on investment for vinyl window replacement in Chicago and 73 percent for wood window replacement, adding more than $14,000 in home resale value per HomeBuild Windows’ 2025 analysis. Energy savings from replacing single-pane windows with ENERGY STAR-certified units range from $125 to $350 annually per HomeBuild’s Chicago market data. Homeyou documents up to 40 percent energy cost reduction replacing old Chicago windows with new efficient units. Window replacement consistently ranks in the top 5 home improvement projects by ROI per Homeyou’s Chicago analysis. For Chicago homeowners planning to sell or seeking long-term energy cost reduction, new windows are among the most financially sound home improvements available.
