Window Replacement Timeline in Boise
A realistic, phase-by-phase look at how long window replacement projects take in Boise and the Treasure Valley. From initial consultation through final inspection, know what to expect at every stage.
Window replacement timelines vary significantly based on the number of windows, installation method, and whether structural modifications are needed. Here is how long each type of project typically takes from start of installation to completion in the Boise market.
1 - 3 Windows
Half Day - 1 Day
Small projects — replacing a single failed window, upgrading a few key windows on the west-facing side, or adding an egress window to a basement bedroom. Insert replacements for standard double-hung or casement windows can be completed in 30 to 60 minutes per window. Including trim, insulation, and cleanup, a 1 to 3 window project typically wraps up in a single morning or afternoon.
4 - 8 Windows
1 - 2 Days
A partial replacement — one floor of a two-story home, all bedrooms, or the front-facing windows for curb appeal improvement. This is common in Boise when homeowners prioritize the worst-performing windows first or want to upgrade the most visible windows for resale. We complete one section of the home each day, ensuring no openings are left unsecured overnight.
10 - 15 Windows
2 - 3 Days
A whole-house replacement for a standard Boise ranch home or smaller two-story. At 4 to 6 windows per day, the installation crew works through the home systematically — typically starting with the most critical exposures (north and west-facing) and finishing with less critical locations. Interior and exterior trim work happens as each window is completed.
16 - 25+ Windows
3 - 5 Days
A full replacement for a larger Boise home with 16 or more windows. Common in the larger homes in Southeast Boise, Eagle, and custom neighborhoods. The additional time accounts for specialty windows (bay/bow, picture windows, arched transoms), second-story access requiring ladders or scaffolding, and the extended trim and finishing work for more complex configurations.
A window replacement project moves through distinct phases from first contact to final walkthrough. Understanding each phase helps you plan and set realistic expectations. Here is the sequence we follow at Iron Crest Remodel for a typical whole-house replacement.
Home Assessment & Measurement
1 - 2 HoursAn Iron Crest specialist visits your home to measure every window opening, assess the condition of existing frames and sills, check for water damage or rot, and evaluate accessibility for installation. We photograph each window and note the exposure direction (north, south, east, west) to recommend the optimal glass package for each location. This is also when we determine if your project requires building permits.
- Precise measurement of all openings
- Frame and sill condition assessment
- Insert vs. full-frame recommendation
- Glass package recommendations by exposure
Product Selection & Proposal
1 - 2 WeeksBased on the assessment, we present options at multiple price points with detailed specifications for frame material, glass package, hardware, and color. We bring physical samples and discuss the trade-offs between budget, mid-range, and premium options. A detailed written proposal with per-window and project-total pricing is provided. Review our window materials guide to research options in advance.
- Frame material and color selection
- Glass package specification
- Grid pattern and hardware options
- Detailed written proposal and pricing
Manufacturing & Delivery
3 - 6 WeeksOnce you approve the proposal and sign the contract, we place the order with the manufacturer. Custom windows are built to your exact specifications — frame color, glass type, hardware, grid pattern, and size. Standard configurations from major manufacturers typically take 3 to 4 weeks. Custom shapes, specialty glass, or unusual sizes may take 6 to 10 weeks. We confirm the delivery date and schedule your installation as soon as the ship date is confirmed.
- Order placed with manufacturer
- Custom fabrication to specifications
- Quality inspection upon delivery
- Installation date confirmed
Old Window Removal
15 - 45 Min Per WindowThe existing window sash, hardware, and weatherstripping are removed. For insert replacements, the existing frame remains in place and is cleaned and prepped. For full-frame replacements, the entire frame, trim, and exterior casing are removed down to the rough opening. The rough opening is inspected for water damage, rot, or structural issues. Interior drop cloths protect flooring and furnishings during the process.
Frame Prep & Repair
15 - 60 Min Per Window (if needed)For full-frame replacements, the rough opening is checked for square, level, and plumb. Any rotted wood is cut out and replaced with new framing lumber. Flashing tape (self-adhesive waterproof membrane) is applied to the sill and jambs to prevent future water infiltration. This step is critical in older Boise homes where decades of moisture exposure may have compromised the framing around the window.
New Window Installation
20 - 45 Min Per WindowThe new window unit is test-fitted, shimmed for level and plumb, and secured to the rough opening or existing frame with screws. The operation of the sash is tested — smooth opening, closing, locking, and tilting (for double-hung units). Low-expansion foam insulation is applied around the perimeter between the window frame and the rough opening to seal air gaps. Exterior caulk is applied to create a weather-tight seal against the siding or brick.
Trim & Finishing
15 - 30 Min Per WindowInterior trim (casing) is reinstalled or replaced. For insert replacements, the existing interior trim is typically preserved. For full-frame replacements, new interior casing is installed, caulked, and touch-up painted. Exterior trim and aluminum capping (coil stock) are applied to cover the transition between the new window frame and the existing siding. This provides a clean, finished appearance and protects the perimeter from weather.
Final Inspection & Walkthrough
1 - 2 HoursAfter all windows are installed, we conduct a thorough walkthrough with you. Every window is opened, closed, locked, and inspected for proper operation, seal integrity, and finish quality. We demonstrate the tilt-in cleaning feature (on double-hung units), hardware operation, and screen installation. If a permit was pulled, the building inspection is scheduled. All old windows and debris are removed from the property. Warranty documentation is provided for both the windows and our installation labor.
Several factors specific to the Boise market and your individual project can extend or shorten the overall timeline. Understanding these helps set realistic expectations.
Manufacturing Lead Times
Manufacturing lead time is the single largest factor in your total project timeline. Standard custom-ordered windows take 3 to 6 weeks from order to delivery. During peak season (spring through early summer), lead times can extend to 6 to 8 weeks as manufacturers process higher order volumes. Placing your order in late fall or winter often results in shorter lead times and faster project completion.
Hidden Frame Damage
Removing old windows sometimes reveals rotted framing, water damage behind the siding, or deteriorated sheathing that must be repaired before the new window can be installed. This is most common in Boise homes built before 1985, particularly around bathroom and kitchen windows where moisture exposure is highest. Each damaged opening adds 1 to 3 hours for framing repair. We budget contingency time for this possibility.
Weather Conditions
Window replacement requires exterior work, so weather matters. We do not install during active rain because water must not enter the wall cavity. Extreme cold (below 15 to 20 degrees Fahrenheit) can affect sealant curing and expanding foam performance. Boise's climate is generally favorable for window work from March through November. Winter installations are possible on dry days above 20 degrees, which Boise provides frequently even in January and February.
Second-Story Access
Windows on the second floor require ladder or scaffold access from the exterior. This slows the per-window installation time by 20 to 40 percent compared to ground-floor windows. Scaffold setup adds time at the beginning of the project but provides safer, more efficient access for multiple second-floor windows. We assess access requirements during the initial home visit.
Specialty Window Types
Bay and bow windows, arched transoms, and custom geometric shapes take significantly longer to install than standard rectangular windows. A bay window replacement can take half a day or more because it involves structural support, multiple glass panels, and precise alignment. If your project includes specialty windows, we factor the additional time into the schedule.
Permit Processing
Like-for-like window replacements do not require a permit. If your project involves changing window sizes, adding new openings, or installing egress windows, the City of Boise or Ada County permit review adds 1 to 3 weeks to the pre-installation timeline. We submit permits early in the planning phase so approval is typically in hand before the windows arrive from the manufacturer. See our window permit guide for details.
Here is a realistic timeline for our most common window replacement project in the Boise market: a 15-window whole-house replacement with mid-range vinyl windows, Low-E glass, and argon fill using the insert replacement method.
| Week | Phase | What Happens |
|---|---|---|
| Week 1 | Home Assessment | On-site measurement of all 15 openings. Frame condition assessment. Insert vs. full-frame determination. Photos and exposure mapping. |
| Week 1-2 | Product Selection | Review options at 3 price points. Select frame color, glass package, grid pattern, and hardware. Finalize proposal and sign contract. |
| Week 2 | Order Placed | Windows ordered from manufacturer with exact specifications. Permit submitted if structural changes are involved. Delivery date confirmed. |
| Week 5-7 | Windows Delivered | Windows arrive at our warehouse. Each unit is inspected for correct size, color, glass type, and defect-free condition before scheduling installation. |
| Week 6-8, Day 1 | Installation Day 1 | First 5-6 windows installed. Old windows removed, openings prepped, new windows shimmed and secured, foam insulation applied, interior and exterior trim completed. |
| Day 2 | Installation Day 2 | Next 5-6 windows installed. Same process. All windows on one elevation completed before moving to the next for consistent exterior appearance. |
| Day 3 | Installation Day 3 | Final 3-5 windows installed. Specialty windows (if any) installed last. Full exterior caulking and capping completed. All screens installed. |
| Day 3-4 | Final Walkthrough | Every window tested for operation, lock function, and seal integrity. Debris removed. Warranty documentation provided. Building inspection if permitted. |
* Total project timeline: 6 to 8 weeks from initial assessment to completion. Active on-site installation time: 3 days. The majority of the timeline is consumed by the manufacturing lead time, during which there is no disruption to your home.
Boise's four distinct seasons each offer different advantages and considerations for window replacement timing.
Spring (March - May)
Excellent installation conditions with moderate temperatures ideal for sealant curing. Start planning in January to February so windows are manufactured and ready for spring installation. This is when demand begins to increase, so early ordering is advantageous.
Summer (June - August)
Long daylight hours allow more installation time per day. However, this is the busiest season with the longest manufacturer lead times and highest contractor demand. Boise temperatures above 95 degrees can make exterior work uncomfortable. Schedule early — ideally ordering windows by April for summer installation.
Fall (September - November)
The sweet spot for Boise window replacement. Comfortable temperatures, decreasing demand, and shorter manufacturer lead times. Getting new windows in before Boise's cold season means you immediately benefit from improved insulation when you need it most. Order in July or August for fall installation.
Winter (December - February)
Lowest demand period with the most competitive pricing and shortest lead times. Installation is possible on dry days above 20 degrees Fahrenheit — Boise provides many such days even in midwinter. The brief exposure during window swap (30 to 60 minutes per window) is manageable. Some manufacturers offer winter promotions.
Common questions about window replacement scheduling and timelines in the Boise area.
How long does a full house window replacement take in Boise?
A full house window replacement with 15 to 20 windows typically takes 3 to 5 days of on-site installation. The total project timeline from initial consultation to completion is 5 to 10 weeks because it includes a home assessment, product selection, custom manufacturing (3 to 6 weeks), and the installation itself. Insert replacements move faster than full-frame replacements. We typically install 4 to 6 windows per day, completing a section of the home each day so no area is left exposed overnight.
What is the best time of year to replace windows in Boise?
Spring (April through May) and fall (September through October) are the ideal seasons for window replacement in Boise. Temperatures are moderate, allowing sealants and expanding foam to cure properly. Summer works well but is the busiest season, with longer lead times and higher demand. Winter installation is possible in Boise — modern sealants can be applied down to 20 degrees Fahrenheit — and you may benefit from off-peak pricing and shorter lead times. We avoid scheduling during active rain or extreme cold below 15 degrees.
How long is the lead time for custom windows?
Standard custom-ordered windows from major manufacturers like Milgard, Andersen, and Pella typically have a 3 to 6 week manufacturing lead time from order confirmation to delivery at our Boise warehouse. Standard sizes in stock configurations may be available in 1 to 2 weeks. Custom shapes (arches, trapezoids, circles), specialty glass packages, or unusual sizes extend lead times to 6 to 10 weeks. We recommend starting the selection process early to avoid delays.
Can I stay home during window replacement?
Yes. Unlike a kitchen or bathroom remodel, window replacement does not require you to vacate your home. The work happens one window at a time, and each opening is typically exposed for only 30 to 60 minutes during the swap. We seal each window completely before moving to the next. However, there will be noise from trim removal, caulking, and finishing work. Dust is minimal since most work is exterior. We recommend keeping pets away from active work areas.
What causes window replacement delays in Boise?
The most common delay is manufacturing lead time, which can extend during peak season (spring and summer) when manufacturers are at capacity. Other factors include discovering rotted framing or water damage during removal (requiring carpentry repair before the new window goes in), weather delays during extreme cold or rain, and permit processing time if structural changes are involved. We build contingency into our timelines and communicate any changes immediately.
