Window Styles We Offer
Double Hung Windows
Our most popular style featuring two vertically sliding sashes. Perfect for traditional homes, these windows provide excellent ventilation control and are easy to clean with tilt-in sash designs. Ideal for bedrooms, living rooms, and kitchens.
Sliding Windows
Featuring horizontal sashes that glide smoothly along tracks, sliding windows are perfect for modern homes and spaces with width constraints. Their simple operation and unobstructed views make them excellent choices for rooms facing patios or gardens.
Casement Windows
Hinged on one side and opening outward with a crank mechanism, casement windows provide maximum ventilation and unobstructed views. Their tight seal when closed makes them among the most energy-efficient options available, perfect for areas requiring superior insulation.
Awning Windows
Hinged at the top and opening outward from the bottom, awning windows allow for ventilation even during light rain. Their design makes them ideal for basements, bathrooms, or above other windows and doors where space is limited.
Bay Windows
Extending outward from your home’s exterior wall, bay windows create additional interior space while flooding rooms with natural light from multiple angles. These dramatic architectural features add character and value to any home while providing panoramic views.
Picture Windows
Fixed, non-opening windows designed to frame outdoor views like artwork. Their large, uninterrupted glass area maximizes natural light and offers superior energy efficiency. Perfect for living rooms or areas where ventilation isn’t a primary concern.
Hopper Windows
Hinged at the bottom and opening inward from the top, hopper windows are space-efficient solutions for basements and small areas. Their design provides excellent security while still allowing ventilation in tight spaces.
