Different window styles serve different purposes and come at different price points. Here is how the most common window types installed in Boise homes compare in cost, including the window unit and standard installation labor.
| Window Type | Budget | Mid-Range | High-End | Best For |
|---|---|---|---|---|
| Double-Hung | $300 - $450 | $450 - $800 | $800 - $1,200 | Bedrooms, living rooms, most common in Boise homes |
| Casement (Crank-Out) | $350 - $500 | $500 - $900 | $900 - $1,400 | Kitchens, bathrooms, superior air seal when closed |
| Picture (Fixed) | $250 - $400 | $400 - $700 | $700 - $1,200 | Living rooms, great rooms, framing Boise Foothills views |
| Bay/Bow Window | $1,200 - $1,800 | $1,800 - $3,500 | $3,500 - $6,000+ | Dining rooms, master bedrooms, curb appeal focal points |
| Sliding (Glider) | $300 - $450 | $450 - $750 | $750 - $1,100 | Bedrooms, basements, wide openings with limited clearance |

| Egress (Basement) | $1,500 - $2,500 | $2,500 - $4,000 | $4,000 - $6,000 | Basement bedrooms, code compliance, includes well and excavation |
* Bay/bow and egress window pricing includes structural framing, insulation, and finishing work. Egress pricing includes window well installation and excavation for basement applications. All prices include standard installation labor in the Boise market.
Most Boise homeowners replace all windows at once rather than piecemeal, which provides volume pricing, consistent appearance, and a single warranty start date. Here is what to expect for whole-house window replacement by project size.
| Project Size | Budget Vinyl | Mid-Range | High-End | Typical Home |
|---|---|---|---|---|
| 10 Windows | $3,000 - $5,000 | $5,000 - $9,000 | $9,000 - $15,000 | Small ranch, condo, or townhome |
| 15 Windows | $4,500 - $7,500 | $7,500 - $13,500 | $13,500 - $22,500 | Average 3-bedroom Boise home |
| 20 Windows | $6,000 - $10,000 | $10,000 - $18,000 | $18,000 - $30,000+ | Larger 4-bedroom or two-story home |
| 25+ Windows | $7,500 - $12,500 | $12,500 - $22,500 | $22,500 - $37,500+ | Large custom homes, Eagle/SE Boise |
* Pricing assumes a mix of standard double-hung and fixed windows. Bay/bow windows, specialty shapes, and egress conversions are priced separately. Volume discounts of 5 to 10 percent are common on projects of 15 or more windows.
Every window replacement project is composed of individual cost elements. Understanding where your money goes helps you make informed decisions about upgrades and where to allocate your budget.
| Component | Low Range | High Range | % of Total |
|---|---|---|---|
| Window Unit (frame + glass) | $150 | $800+ | 40-55% |
| Installation Labor | $100 | $400 | 20-30% |
| Interior Trim & Finishing | $50 | $200 | 8-15% |
| Exterior Capping/Cladding | $30 | $150 | 5-10% |
| Foam Insulation & Sealant | $15 | $50 | 2-5% |
| Old Window Removal & Disposal | $25 | $75 | 3-5% |
| Permits (if required) | $0 | $300 | 0-3% |
* Component costs are per window. Full-frame replacement adds $100 to $250 per window for frame removal, rough opening preparation, flashing, and additional insulation. General contractor overhead (typically 15 to 20 percent) is included in the per-window installed prices above.
Boise sits in IECC Climate Zone 5, with winter lows regularly in the single digits and summer highs exceeding 100 degrees Fahrenheit. Windows are responsible for 25 to 30 percent of a home's heating and cooling energy loss. Upgrading to modern, energy-efficient windows delivers measurable savings on Idaho Power and Intermountain Gas bills.
Annual Savings by Upgrade Path
Single-Pane to Double-Pane Low-E
$600 - $1,200/year
The largest improvement. Single-pane windows (common in Boise homes built before 1980) have a U-factor of approximately 1.0. Replacing with Low-E double-pane windows (U-factor 0.28 to 0.30) reduces heat transfer by over 70 percent. At current Idaho Power rates of approximately $0.09 per kWh and Intermountain Gas heating costs, this translates to $600 to $1,200 in annual savings for a typical 15-window Boise home.
Failed Double-Pane to New Double-Pane
$300 - $700/year
Double-pane windows with broken seals (visible fog or condensation between panes) have lost their insulating gas fill and perform nearly as poorly as single-pane. Replacing failed units restores the full insulating value of the IGU (insulated glass unit) and eliminates the drafts and condensation that failed seals create.
Double-Pane to Triple-Pane
$200 - $500/year
Upgrading from functioning double-pane to triple-pane provides incremental savings that are most noticeable on north-facing and west-facing walls. Triple-pane windows also significantly reduce exterior noise — a benefit for Boise homes near major roads like Eagle Road, State Street, or the freeway corridor.
Rebates & Tax Credits
Federal 25C Tax Credit
The Energy Efficient Home Improvement Credit allows homeowners to claim 30 percent of the cost of qualifying Energy Star Most Efficient windows, up to $600 per year. The credit is available through 2032. Windows must meet the Energy Star Most Efficient criteria for Climate Zone 5 (U-factor 0.25 or lower, SHGC 0.40 or lower). This is a tax credit, not a deduction, meaning it directly reduces your tax liability dollar-for-dollar.
Idaho Power Efficiency Programs
Idaho Power offers various energy efficiency rebates that may apply to window upgrades. Program availability and qualifying criteria change periodically. We recommend checking the current offerings at Idaho Power's website before finalizing your window selections. Historically, rebates of $1 to $3 per square foot of qualifying window area have been available for homes converting from electric heating.
Payback Period Estimate
For a typical 15-window Boise home replacing single-pane windows with mid-range Energy Star windows at $10,000 to $13,000 total cost, the combination of annual energy savings ($600 to $1,200), federal tax credit ($600 year one), and potential utility rebates can reduce the effective payback period to 8 to 12 years. Given that quality windows last 20 to 30 years, the net lifetime savings are substantial.
Window replacement costs are not the same everywhere. Several factors unique to Boise, Ada County, and the Treasure Valley directly influence what you will pay for your project.
UV Exposure & Solar Heat
Boise receives over 200 sunny days per year with intense UV exposure, especially on south and west-facing elevations. West-facing windows absorb the worst afternoon heat in summer, making Low-E coatings with low SHGC values (0.25 or lower) critical. Without proper solar control coatings, cooling costs spike in July and August. Budget $50 to $100 more per window for enhanced solar control glass on sun-exposed sides.
Housing Age & Frame Condition
Boise's North End and Bench neighborhoods have homes built from the 1920s through 1970s, many with original wood-frame single-pane windows. These often require full-frame replacement because the existing frames are rotted, warped, or out of square. Homes in newer subdivisions in Meridian, Eagle, and Star (built 1990s to 2010s) typically have failing double-pane vinyl windows that can be replaced with the simpler insert method, saving $100 to $250 per window in labor and materials.
Idaho Labor Rates
Window installation labor in the Boise market runs $100 to $400 per window depending on window type, size, and accessibility. Two-story installations requiring exterior ladder or scaffold access add 20 to 40 percent to labor costs. The Treasure Valley's installation labor rates are below coastal markets like Portland and Seattle but have increased 15 to 20 percent since 2020 due to population growth and construction demand.
Seasonal Pricing
Window replacement in Boise is best scheduled in spring or fall when temperatures are moderate for sealant curing and outdoor comfort. However, late fall and winter (November through February) is the off-peak season when contractors often offer more competitive pricing and manufacturers may run promotional pricing. Summer is the busiest season, with longer lead times and less scheduling flexibility.
Manufacturing Lead Times
Custom-ordered windows from major manufacturers (Milgard, Andersen, Pella, Marvin) typically have 3 to 6 week lead times from order to delivery in the Boise market. Standard sizes in popular configurations may be available sooner. Custom shapes, colors, or specialty glass packages extend lead times to 6 to 10 weeks. We recommend ordering early in your planning process to avoid delays.
Permit & Code Costs
Like-for-like window replacements in Boise typically do not require a permit. However, changing window sizes, adding new openings, or installing egress windows requires a building permit ($150 to $300) and structural review. All replacement windows must meet current energy code requirements for Climate Zone 5 regardless of whether a permit is pulled. See our window replacement permit guide for details.
Window replacement is consistently rated as one of the best exterior improvement investments for resale value and daily living comfort in the Treasure Valley.
Resale Value Data
Vinyl Window Replacement: 67–73% ROI
A $12,000 whole-house vinyl window replacement in Boise typically adds $8,000 to $8,800 in resale value. More importantly, updated windows are one of the first things buyers notice from the curb and during walkthroughs. Homes with visibly old or foggy windows spend longer on market and receive lower offers.
Wood-Clad Window Replacement: 63–69% ROI
Wood and wood-clad windows cost more but recoup a slightly lower percentage. They are the best choice for historic homes in Boise's North End and Harrison Boulevard districts where maintaining architectural character matters for both aesthetics and potential historic review requirements.
Comfort & Noise Reduction: Value Beyond ROI
New windows eliminate drafts, reduce exterior noise by 50 to 70 percent, and provide consistent room temperatures throughout the house. Boise homeowners consistently report that the comfort improvement alone justifies the investment, especially in older homes where single-pane windows make certain rooms unusable in winter.
Beyond Resale: Daily Living Value
ROI calculations focus on resale, but most Boise homeowners live with their new windows for 10 to 20 years before selling. The daily improvement in comfort, energy efficiency, UV protection for furnishings, and noise reduction delivers quality-of-life value that does not show up in a cost-recovery percentage.
Modern Low-E coatings block 70 to 80 percent of UV radiation, protecting hardwood floors, carpet, furniture, and artwork from sun fading. In Boise's high-sun environment, UV damage to interior furnishings is a real and costly problem that new windows prevent.
New windows also reduce HVAC system strain. When your furnace and air conditioner work less hard to maintain temperature, they last longer and require less maintenance. Over a 15-year window lifespan, reduced HVAC wear adds another $1,000 to $3,000 in avoided maintenance and replacement costs.
Curb appeal improvement is immediate and dramatic. Consistent window style, clean lines, and modern frames can transform the exterior appearance of a dated Boise home. This is especially impactful for homes in competitive neighborhoods where buyers compare properties side by side. Explore our window design ideas guide for style inspiration.
These strategies can help Boise homeowners manage costs without compromising window quality or energy performance.
Choose Insert Over Full-Frame When Possible
If your existing window frames are square, solid, and free of rot, insert replacement saves $100 to $250 per window compared to full-frame. Have a contractor inspect the frames before deciding — do not assume inserts will work in older Boise homes without verification.
Replace All Windows at Once
Whole-house replacement projects benefit from volume pricing, single-mobilization labor costs, and consistent manufacturer ordering. Replacing 15 to 20 windows at once typically saves 5 to 10 percent compared to doing them in batches of 3 to 5 over several years.
Prioritize Worst-Performing Windows First
If budget is limited, replace the worst-performing windows first: single-pane windows, failed double-pane windows with visible fog, and windows on the north and west exposures. These deliver the highest energy savings per dollar spent in Boise's climate.
Maximize Federal Tax Credits
The 25C credit offers up to $600 per year for qualifying windows. If you are replacing 20 or more windows, consider splitting the project across two tax years to claim $600 in each year — a $1,200 total credit instead of $600. Consult a tax professional for your specific situation.
Schedule During Off-Peak Season
Late fall and winter in Boise is the off-peak window installation season. Contractors may offer better pricing, manufacturers sometimes run promotions, and scheduling is more flexible. Modern sealants and foams can be applied in temperatures down to 20 degrees Fahrenheit.
Select Quality Mid-Range Over Premium
Premium fiberglass and wood-clad windows are beautiful, but a quality mid-range vinyl window with Low-E glass and argon fill delivers 90 percent of the energy performance at 40 to 50 percent less cost. For most Boise homes, mid-range vinyl is the smart value choice.
Common questions Boise homeowners ask about window replacement costs.
How much does it cost to replace one window in Boise?
A single window replacement in Boise ranges from $300 for a basic builder-grade vinyl double-hung to $1,500 or more for a premium fiberglass or wood-clad casement window with triple-pane glass. The most common replacement in the Treasure Valley market is a mid-range vinyl or fiberglass double-hung window with Low-E glass and argon fill, which typically costs $500 to $900 installed. This includes the window unit, removal and disposal of the old window, installation labor, foam insulation around the frame, and interior and exterior trim finishing.
How much does a full house window replacement cost in Boise?
A full house window replacement in Boise typically costs $5,000 to $15,000 for 10 windows, $7,500 to $22,500 for 15 windows, and $10,000 to $30,000 or more for 20 windows. The per-window cost decreases slightly on larger projects due to mobilization and labor efficiencies. The total depends on window type, frame material, glass package, and whether you need insert replacements or full-frame replacements. Full-frame replacements cost 20 to 40 percent more because the existing frame and trim are removed down to the rough opening.
Are window replacements worth the cost in Boise?
Yes. Window replacement is one of the highest-ROI exterior improvements in the Boise market. The national average recoup rate is 67 to 73 percent at resale for vinyl window replacements and 63 to 69 percent for wood-clad. Beyond resale, Boise homeowners typically save 15 to 25 percent on heating and cooling costs after replacing single-pane or failed double-pane windows. With Idaho Power residential rates and Intermountain Gas heating costs, most Boise homeowners see $400 to $1,200 per year in energy savings, which means the windows begin to pay for themselves within 8 to 15 years.
Does Idaho Power offer rebates for window replacement?
Idaho Power periodically offers energy efficiency rebates that may apply to qualifying window upgrades. Additionally, the federal Energy Efficient Home Improvement Credit (Section 25C) allows homeowners to claim up to $600 per year for Energy Star Most Efficient certified windows through 2032. The windows must meet specific U-factor and SHGC requirements for Climate Zone 5. We recommend checking Idaho Power's current rebate offerings and consulting a tax professional about federal credits before finalizing your window selection.
What is the difference between insert and full-frame window replacement?
Insert replacement (also called pocket replacement) installs a new window unit inside the existing frame, preserving the original frame, trim, and siding. This is faster, less disruptive, and costs 20 to 40 percent less than full-frame replacement. Full-frame replacement removes everything down to the rough opening, allowing inspection and repair of the framing, improved insulation, and potentially a slightly larger glass area. Full-frame is recommended when the existing frame is rotted, warped, or water-damaged, which we commonly see in Boise homes built before 1985.
