Why Choose Retrofit Windows for Your Gilbert Home
Saves Money on Window Replacement
Retrofit window installation costs 20-30% less than full frame replacement because we keep your existing window frame. If your current frames are in good condition, retrofit installation gives you new windows without the expense of complete frame replacement. Many Gilbert homeowners choose retrofit to upgrade their windows affordably.
Faster Installation Process
Retrofit installation takes half the time of full frame replacement. Most Gilbert homes get retrofit windows installed in one day instead of two or three days. We don’t need to remove trim, repair drywall, or touch up paint. You get new windows with minimal disruption to your daily routine.
Less Mess and Disruption
Since we keep existing frames, retrofit installation creates much less mess inside your home. No drywall dust, no paint touch-ups, and no trim removal. We protect your floors and furniture, but there’s simply less work involved. Perfect for busy Gilbert families who want new windows without major construction.
Maintains Existing Trim and Finishes
Your interior and exterior trim stays untouched during retrofit installation. This preserves your home’s existing appearance and avoids the cost of refinishing or replacing trim work. Especially valuable in Gilbert’s older neighborhoods where matching existing finishes can be challenging.
Improves Energy Efficiency Significantly
Even though we keep the existing frame, new retrofit windows with modern glass and sealing technology dramatically improve energy efficiency. You get Low-E glass, improved weatherstripping, and better insulation. Many Gilbert homeowners see 25-35% energy savings with retrofit window installation.
Perfect for Stucco Homes
Many Gilbert homes have stucco exteriors that are expensive to repair after full frame window replacement. Retrofit installation doesn’t disturb the stucco around your windows, saving hundreds of dollars in exterior repairs. This makes retrofit the smart choice for most stucco homes.
When Retrofit Works Best
Retrofit installation works when your existing window frames are structurally sound and properly sized. We assess each window frame to make sure retrofit is the right choice. If frames are rotted, damaged, or improperly sized, we recommend full replacement instead.
Professional Assessment Required
Not every window is a good candidate for retrofit installation. Our team inspects your existing frames carefully to determine if retrofit will give you the performance you want. We’re honest about when full replacement would be better for your specific situation.


Our Professional Window Replacement Process
Affordable Pricing & Cost Savings
Retrofit window installation costs less than full frame replacement while still giving you modern window performance. Here’s what Gilbert homeowners typically invest:
Standard Vinyl Retrofit Windows: $350-$550 per window installed
Premium Vinyl Retrofit Windows: $450-$650 per window installed

Retrofit vs. Full Replacement Savings
Retrofit installation typically saves $150-300 per window compared to full frame replacement. For a whole house project, this can mean savings of $3,000-6,000 or more. The energy efficiency and appearance benefits are nearly identical to full replacement.
When Retrofit Isn’t Right
If your existing frames need replacement, full frame installation is the better choice. We’re honest about when retrofit won’t work and explain why full replacement would serve you better. Our goal is the right solution for your home, not just the cheapest option.
Volume Pricing Available

Older Gilbert Communities
Many of Gilbert’s established neighborhoods built in the 1980s and 1990s have window frames perfect for retrofit installation. We’ve completed numerous retrofit projects in these areas where homeowners want updated windows without major construction.
HOA-Friendly Approach
Retrofit installation usually doesn’t change your home’s exterior appearance, making HOA approval simpler. The new windows look virtually identical to full replacement windows from outside. We help with any HOA documentation needed.
