Window Styles We Install
We install every major window style — custom-measured and fitted to your home.
Double Hung Windows
The most popular choice for Buffalo homes. Both sashes tilt in for easy cleaning, and they provide excellent ventilation control. Available in dozens of colors and grid patterns.
Casement Windows
Hinged on the side and cranked open outward, casement windows provide maximum ventilation and an unobstructed view. Great for hard-to-reach areas like above kitchen sinks.
Bay & Bow Windows
Add architectural interest and extra interior space with a stunning bay or bow window. Perfect for living rooms and dining areas — they flood your home with natural light.
Sliding Windows
Sleek and easy to operate, sliding windows glide horizontally and are ideal for wide openings where a casement or hung window isn't practical.
Picture Windows
Fixed, non-opening windows that frame your view like a painting. Ideal for living rooms and great rooms where maximum light and views are the priority.
Awning Windows
Hinged at the top and opening outward, awning windows let in fresh air even during light rain — a smart choice for Buffalo's unpredictable weather.
Built for Buffalo Winters
Western New York winters are brutal. Our replacement windows are engineered to handle them — with triple-pane glass options, low-E coatings, argon gas fills, and warm-edge spacer technology that dramatically reduces heat loss. Most homeowners see heating and cooling savings of up to 30% after replacing old single-pane or failed double-pane windows.
Triple-Pane Glass
Superior insulation against Buffalo's harsh winters with three layers of glass and two insulating gas fills.
Low-E Coating
Reflects heat back into your home in winter and blocks solar heat gain in summer — year-round comfort.
Argon Gas Fill
Dense argon gas between panes dramatically reduces heat transfer compared to standard air-filled windows.
Energy Star Certified
All our windows meet or exceed Energy Star requirements for the Northern climate zone — including Buffalo.
