Why replace
What new windows actually get you

~72%
Average return on investment at resale (Remodeling Impact Report).
Up to 50%

20+ yrs

Window types
A style for every opening
Not sure what you have, or what you want? Here's a quick tour of the styles and install types you'll see quoted most often, from double-hung and casement to sliding glass doors and retrofit windows.
Casement
Hinged at the side and cranked outward. Best air seal of any operable window and unobstructed views.
Sliding
Horizontal glide, wider than tall. Ideal for modern homes, ranch layouts, and rooms facing patios.
Bay & Bow
Three or more windows projecting outward. Adds square footage, natural light, and dramatic curb appeal.
Picture
Fixed, non-operable glass that maximizes view and energy efficiency. Common as a centerpiece window.
Awning
Hinged at the top, opens outward. Great for ventilation during light rain and above kitchen sinks.
Sliding Glass Doors
Two-, three-, or four-panel patio doors that glide horizontally. Vinyl sliding door installation is the most affordable way to open a wall of glass onto a deck, patio, or backyard.
Retrofit Windows
Insert-style replacements that slip into your existing frame with no stucco cutting or interior drywall damage. The fastest, least-invasive option when the original frame is sound.
Frame materials
Vinyl, wood or fiberglass: which is right for you?
Frame material drives cost, efficiency, and how often you'll ever think about your windows again. Vinyl windows and doors dominate the retrofit market for a reason: lowest price, best warranty and near-zero maintenance.
| Material | Cost | Durability | Efficiency | Maintenance | Best for |
|---|---|---|---|---|---|
| Vinyl | $ | 20–40 yrs | High | Very low | Best overall value |
| Fiberglass | $$$ | 40–50 yrs | Highest | Low | Best long-term ROI |
| Wood | $$$$ | 30+ yrs | High | High | Historic and premium homes |
| Aluminum | $$ | 20–30 yrs | Low–Med | Low | Modern, large openings |
| Composite | $$$ | 30+ yrs | High | Low | Wood look, vinyl performance |
