What Is Window Capping?

Window capping involves covering exposed wooden or vinyl window frames with a protective layer, usually made from aluminum or PVC. This forms a barrier against moisture, pests, and weather, and can be colored to match or accent your home’s exterior. Window capping eliminates the need for frequent painting, reduces rot, and boosts not just aesthetics but also longevity.

Why Homeowners Choose Window Capping

• Minimizes Maintenance: Capped windows do not need painting or scraping, saving time and ongoing expense.
• Weather Protection: Aluminum or PVC wraps prevent water infiltration and wood rot, and resist rust and UV fading.
• Improves Curb Appeal: Professionally capped windows create clean lines and a polished, modern look.
• Enhances Energy Efficiency: Proper capping seals gaps, reducing drafts and utility costs.

Main Factors Affecting Window Capping Cost

Numerous variables contribute to the final cost of window capping. It’s important to understand these influences before soliciting quotes or starting a project.

Window Size And Shape

Larger or unusually shaped windows (arch, bay, picture) require more material and labor. Standard double-hung and single-hung windows are less expensive to cap than oversized or custom designs.

Number Of Windows

The more windows you cap at once, the lower the cost per window. Contractors often offer discounts for whole-home projects.

Material Type

Aluminum is the most common capping material due to its durability, color options, and flexibility. Some homeowners choose PVC for a different look or cost structure. Material pricing can vary by thickness, brand, and finish.

Labor & Installation Complexity

Labor costs rise with multiple stories, hard-to-access windows, or damaged frames that need repair before capping. Homes with intricate trim, exterior details, or challenging ladders create higher bids.

Location & Regional Pricing

Urban areas and regions with higher labor rates tend to have more expensive window capping services. Rural or low-cost-of-living locales may save on installation fees but pay more for travel charges or limited contractor availability.

Accessibility & Preparation Needs

If heavy preparation is needed—such as wood rot repair or heavy sanding—expect the cost to rise. Simple jobs often take only 1-2 hours per window; complex repairs can double installation time and expense.

Average Window Capping Cost Per Window

Type Of Window	Low-End	Average	High-End
Single/Double Hung	$70	$120	$200
Casement Window	$90	$145	$250
Bay/Bow Window	$180	$290	$450+
Arched/Specialty	$160	$230	$400

Most U.S. homeowners pay between $900 and $3,000 to cap all windows on an average-sized home (12-16 windows).

Window Capping Material Costs Breakdown

Material	Average Price Per Sq Ft	Benefits	Drawbacks
Aluminum	$6–$13	Durable, wide color choice, weatherproof, low maintenance	Prone to dents if hit by impact, can be more expensive
PVC/Vinyl	$4–$11	Waterproof, affordable, does not corrode	Limited colors, less flexible for intricate trim
Custom Metal (Copper)	$20–$45	Premium, unique look, extremely durable	Very expensive, rarely needed outside luxury projects

Aluminum is the default choice for most window capping projects due to its cost-effectiveness and performance.

Cost Comparison: Capping Versus Window Replacement

Replacing windows is significantly more expensive than capping existing frames, making capping an attractive alternative for protection and aesthetics if the windows are still structurally sound.

Service	Average Cost Per Window	Benefit
Window Capping	$120–$150	Protects and beautifies, extends life
Window Replacement	$650–$1,800	Full update, better insulation options

20 Windows	$2,200	$2,800	$4,400+

DIY Versus Professional Installation: Cost & Considerations

Skilled homeowners can choose to cap windows as a DIY project to save labor costs. However, professional window capping ensures a seamless, watertight finish and may offer longer-lasting results.

DIY Cost Breakdown

• Materials: $30–$120 per window (aluminum, caulk, fasteners, paint/finish as needed)
• Tools: $70–$300 initial outlay for metal brake, snips, caulk gun, safety gear (reusable for future jobs)
• Labor: Your own time, with each window taking 1–2 hours once experienced

DIY capping may save $60–$130 per window but requires time, precision, and special equipment.

Professional Installation Cost Breakdown

• Labor: $80–$190 per window (includes skilled work, insurance, warranties)
• Materials: Usually included in the quote; higher quality and fitted precisely on-site
• Total: $120–$250+ per window depending on difficulty and project scale

Most homeowners prefer professionals for speed, expertise, and guaranteed waterproofing.

Additional Cost Factors For Window Capping

• Window Frame Repairs: Rotten or damaged frames must be fixed before wrapping; costs can range from $45–$300 per window depending on repair size.
• Two-Story And Above Installations: Adds risk and setup time, typically increasing prices by 10–20%.
• Trim Or Mullion Capping: If you want to wrap exterior trim or mullions, add $15–$50 per linear foot.
• Caulking & Sealant: Quality caulk ($5–$12 per tube) is essential; some installers charge extra for high-end or “permanent” sealants.
• Travel Charges: Remote or rural properties may incur additional fees.

How To Estimate The Total Window Capping Cost For Your Home

1. Count Your Windows: Include all basement, garage, and attic windows if capping is needed throughout.
2. Measure Window Frames: Note width, height, and note if any are bay, bow, or arched types.
3. Assess Accessibility: Flag difficult-to-reach windows or upper stories.
4. Request Local Quotes: Contact three reputable local contractors for onsite estimates including materials and labor.
5. Compare With DIY: Calculate your own skill, tool investments, and time against contractor pricing to find your best value.

Always get itemized written estimates to avoid hidden costs and ensure warranty coverage on both labor and materials.
