Windows are one of the most significant factors in your home's energy performance, comfort, and appearance. In the Treasure Valley, old single-pane and early double-pane windows allow massive heat loss in winter and solar heat gain in summer — driving up energy bills and creating uncomfortable drafts and hot spots throughout the home. Modern replacement windows with Low-E coatings, argon or krypton gas fill, warm-edge spacers, and insulated frames dramatically reduce energy transfer, block UV damage to furnishings, and improve noise reduction. Window replacement involves precise measurement of each opening, factory ordering of custom-sized units, removal of old windows, installation with proper shimming, leveling, insulation, and flashing, and interior and exterior trim finishing. The Boise market offers three primary frame materials — vinyl, fiberglass, and wood-clad — each with distinct advantages in performance, aesthetics, and price that should be matched to the homeowner's priorities and budget.
Star homeowners pursue window replacement for a variety of reasons. Here are the most common situations we see:
- ✓Homeowners with single-pane or aging double-pane windows that are drafty, foggy, or difficult to operate
- ✓Anyone experiencing high heating and cooling bills due to poor window insulation and air leakage
- ✓Homeowners who want to improve comfort by eliminating cold drafts near windows in winter and heat gain in summer
- ✓Property owners replacing failed or broken window seals with foggy or condensation-filled glass
- ✓Homeowners renovating or updating their home's exterior appearance with new window styles and trim
Not every windows project is the same. Here are the most common project types we complete in Star:
Full-Frame Window Replacement
Complete removal of the old window including the frame, and installation of a new window unit with new frame, flashing, and interior and exterior trim. Required when existing frames are damaged, rotted, or need resizing.
Insert (Pocket) Window Replacement
New window unit installed within the existing frame opening, preserving interior and exterior trim. A faster, less invasive installation method when existing frames are in good condition.
Whole-Home Window Package
Replace all windows throughout the home in a single project for maximum energy savings, consistent appearance, and volume pricing. The most cost-effective approach when most or all windows need upgrading.
Picture Window and Specialty Shape Installation
Install fixed picture windows, bay windows, bow windows, arched windows, or custom-shape windows. These specialty units are factory-built to custom dimensions and create dramatic focal points.
Sliding and Patio Door Replacement
Replace sliding glass doors and French patio doors with modern, energy-efficient units featuring multi-point locking, Low-E glass, and improved weatherstripping for better security, insulation, and operation.
Star's housing stock is overwhelmingly post-2015 construction. Modern systems throughout, but builder-grade finishes that homeowners customize over time.
Pre-2010 (limited)
A small number of older homes in the original townsite. These may need system and finish updates.
2015–present (majority)
New construction with modern systems, open floor plans, and builder-grade finishes. Most remodeling focuses on finish upgrades and outdoor living additions.
Common issues in Star homes
- •Builder-grade finishes that homeowners want to personalize
- •Standard builder landscaping and outdoor living that needs development
- •Limited storage in builder-designed kitchens
- •Basic builder lighting packages
Material selection affects the look, durability, and cost of your windows. Here are the most popular options we install in Star:
Vinyl Windows (Milgard, Simonton, Ply Gem)
$400–$800 per window installedThe most popular and cost-effective replacement window option. Modern vinyl frames are energy-efficient, maintenance-free, and available in white and limited color options. Multi-chamber frame designs provide good insulation.
Best for: Budget-conscious whole-home replacements where maximum energy savings per dollar is the priority
Fiberglass Windows (Milgard, Marvin, Pella)
$700–$1,400 per window installedPremium frame material with superior strength, minimal expansion/contraction, and paintable exterior. Fiberglass frames are stronger than vinyl, more dimensionally stable, and offer a narrower profile for more glass area.
Best for: Homeowners who want premium performance, slim profiles, and color options beyond white
Wood-Clad Windows (Andersen, Marvin, Pella)
$900–$1,800+ per window installedReal wood interior with aluminum or fiberglass exterior cladding. Provides the warmth and beauty of wood inside with the weather protection of metal or composite outside. Available in many stain and paint options.
Best for: High-end renovations, historic homes, and homeowners who want real wood interior trim and aesthetics
Low-E Glass with Argon Fill
Included in most quality replacement windowsLow-emissivity coatings and argon gas fill between panes reduce heat transfer by 30-50% compared to standard dual-pane glass. The standard glass package for energy-efficient replacement windows in the Boise climate.
Best for: All replacement windows in the Treasure Valley — standard for energy code compliance
Triple-Pane Glass
$150–$300 premium per window over dual-paneThree panes of glass with two argon or krypton-filled chambers provide maximum insulation. Reduces heat loss, noise transmission, and condensation. Heavier and more expensive than dual-pane but offers the highest energy performance.
Best for: North-facing windows, bedrooms near roads, and homeowners seeking maximum energy performance
Here is how a typical windows project works from first contact to final walkthrough:
1
In-Home Window Assessment
We inspect every window in the home, checking frame condition, seal integrity, glass type, operation, and weatherstripping. We measure each opening and discuss your priorities — energy efficiency, appearance, noise reduction, or all three. You receive a detailed estimate with product options.
2
Product Selection and Ordering
You select window style, frame material, glass package, grid pattern (if any), and interior/exterior color. We recommend products based on your priorities and budget. Windows are factory-ordered to the exact measurements of each opening, with typical lead times of 4-8 weeks.
3
Pre-Installation Preparation
Before installation day, we confirm all window units are received, verify measurements against the openings, and schedule the installation crew. We coordinate interior and exterior finish work scheduling.
4
Old Window Removal
Existing windows are carefully removed — either the sash and frame (full-frame replacement) or sash only (insert replacement). We protect interior floors and furnishings, and inspect the rough opening for damage, moisture, or insulation deficiencies.
5
New Window Installation
New windows are set into the openings, shimmed for level and plumb, and fastened securely. Low-expansion foam insulation fills gaps between the window frame and rough opening. Proper flashing ensures water drainage away from the window.
6
Interior and Exterior Trim Finishing
Interior trim (casing, sill, apron) is installed or replaced. Exterior trim and capping are applied to create a clean, weather-tight finish. All joints are caulked and sealed.
7
Final Inspection and Operation Testing
Every window is tested for smooth operation, proper locking, and seal integrity. We verify all flashing, caulking, and trim is complete and conduct a final walkthrough with the homeowner.
Here is what to expect for project duration when planning a windows in Star:
| Phase | Duration | Details |
|---|---|---|
| Assessment and Product Selection | 1–2 weeks | In-home measurement, product consultation, selection of frame material, glass package, and style, and detailed estimate. |
| Factory Ordering | 4–8 weeks | Windows are factory-built to the exact measurements of each opening. Lead times vary by manufacturer and product line. Custom shapes and colors may take longer. |
| Installation | 1–3 days | A typical whole-home window replacement (15-20 windows) takes 2-3 days. Smaller projects may be completed in a single day. Each window is removed, installed, insulated, and trimmed in sequence. |
| Interior Trim | 1–2 days | Interior casing, sill, and apron installation or touchup. Some projects include full interior trim replacement for a complete refresh. |
| Exterior Finishing | 1–2 days | Exterior trim, capping, caulking, and touch-up painting to complete the weather-tight finish. |
| Final Inspection | 1 day | Operation testing of every window, lock verification, flashing and seal inspection, and homeowner walkthrough. |
Typical range: $6,000 – $35,000+
Most projects: $10,000–$22,000
The final cost of your windows in Star depends on several factors. Here are the biggest cost drivers:
Number of Windows
high impactThe total window count is the primary cost driver. Whole-home replacements of 15-25 windows benefit from volume pricing that reduces per-unit cost. Single-window replacements have higher per-unit costs due to minimum labor charges.
Frame Material
high impactVinyl is the most affordable, fiberglass is mid-range, and wood-clad is the premium option. The frame material alone can create a 2-3x cost difference per window.
Window Size and Style
medium impactStandard double-hung and slider windows are the most affordable. Large picture windows, bay windows, bow windows, and custom shapes cost significantly more due to size, engineering, and manufacturing complexity.
Installation Method
medium impactInsert (pocket) replacement is faster and less expensive because it preserves existing trim. Full-frame replacement costs more due to frame removal, rough opening preparation, new flashing, and trim replacement.
Glass Package Upgrades
low impactTriple-pane glass, specialty Low-E coatings for specific exposures, laminated glass for noise reduction, and impact-resistant glass add $100-300+ per window over standard dual-pane Low-E.
Exterior Trim and Finishing
low impactAluminum capping, PVC trim, or wood trim finishing on the exterior adds cost but creates a clean, weather-tight appearance. The scope of exterior finish work depends on the installation method and existing trim condition.
Problem: Drafty windows causing cold spots and high heating bills in winter
Solution: We replace old single-pane or failed double-pane windows with modern Low-E, argon-filled units that reduce heat loss by 30-50%. Proper insulation around the frame eliminates drafts at the window-to-wall connection.
Problem: Foggy windows with failed seals and condensation between panes
Solution: Failed seals cannot be repaired — the window unit must be replaced. New factory-sealed dual or triple-pane units with quality spacers and seals restore clear views and insulation performance.
Problem: Windows that are difficult to open, close, or lock
Solution: New replacement windows operate smoothly with modern balance systems, tilt-in sashes for easy cleaning, and multi-point locking hardware for improved security.
Problem: Excessive noise from traffic or neighbors
Solution: We recommend dual-pane windows with laminated glass or triple-pane configurations for maximum noise reduction. Proper installation with foam-filled gaps at the rough opening also reduces sound transmission.
Problem: UV damage to furniture, flooring, and artwork near windows
Solution: Low-E glass blocks 70-95% of harmful UV rays while allowing visible light to pass through. This dramatically reduces fading and UV damage to interior furnishings, flooring, and artwork.
Star shares the Treasure Valley climate. Open terrain and rural-edge location mean more wind and UV exposure.
Wind and Open Exposure
Higher wind loads and more UV exposure than sheltered locations. Durable exterior materials are important.
New Construction Settling
Homes 3-7 years old may show minor settling cracks in drywall — cosmetic and common in new construction on Treasure Valley soils.

- ●Grid pattern selection — grids between the glass (GBG) add a traditional look while maintaining easy cleaning; no grids create a clean, modern appearance
- ●Interior color and finish — match window interior color to your trim and millwork; wood-clad windows offer the most interior finish options
- ●Glass performance by exposure — south and west windows benefit from solar-control Low-E coatings; north windows benefit from high-solar-gain Low-E to capture winter warmth
- ●Ventilation planning — ensure enough operable windows for adequate airflow; code requires egress-sized windows in bedrooms for emergency exit
- ●Exterior color coordination — match or complement exterior window color with siding, trim, and front door for cohesive curb appeal

How much do replacement windows cost in Boise?
Replacement windows in the Boise area typically cost $400-800 per window for quality vinyl, $700-1,400 for fiberglass, and $900-1,800+ for wood-clad — including installation. A whole-home replacement of 15-20 windows typically runs $10,000-22,000 for vinyl or $15,000-30,000+ for fiberglass or wood-clad.
How much can new windows save on energy bills?
Replacing single-pane windows with modern Low-E, argon-filled units can reduce heating and cooling costs by 15-30%. The savings are especially significant in Boise's climate with cold winters and hot summers. Triple-pane windows offer even greater savings.
What is the best window brand for Idaho?
Milgard, Simonton, and Ply Gem are excellent vinyl options with strong regional availability. Marvin, Pella, and Andersen offer premium fiberglass and wood-clad lines. We recommend products based on your priorities, budget, and the specific performance requirements of your home.
Do replacement windows qualify for tax credits?
Yes. Energy Star certified windows qualify for federal energy efficiency tax credits under the Inflation Reduction Act. As of 2024, homeowners can claim up to $600 for qualifying window replacements. We can help you identify qualifying products.
How long does window installation take?
A typical whole-home window replacement (15-20 windows) takes 2-3 days of on-site work. The total project timeline, including measurement, ordering, and manufacturing, is typically 6-10 weeks from initial consultation to completion.
Should I replace all windows at once or one at a time?
Replacing all windows at once is more cost-effective per unit due to volume pricing and single mobilization. It also ensures consistent appearance, performance, and warranty coverage throughout the home. We offer phased payment options for whole-home projects.
What is the difference between insert and full-frame replacement?
Insert replacement installs the new window within the existing frame, preserving interior and exterior trim. Full-frame replacement removes everything including the old frame, allowing for new flashing and insulation at the rough opening. Full-frame costs more but addresses the entire window assembly.
How long do replacement windows last?
Quality vinyl replacement windows typically last 20-30 years. Fiberglass and wood-clad windows can last 30-40+ years with proper maintenance. Glass seal warranties from major manufacturers range from 10-20 years.
