Energy Star CertifiedWhat Affects Your Window Price?
Window Size
Larger or custom-sized windows cost more due to increased material and glass. Standard sizes are the most affordable.
Glass Package
Double-pane with low-E coating is standard. Triple-pane with dual low-E and krypton gas adds $150-250 per window.
Frame Material
Vinyl is the most affordable and maintenance-free. Fiberglass and wood-clad frames are premium options.
Number of Windows
Whole-house projects get better per-window pricing. We offer volume discounts starting at 8+ windows.
Existing Condition
Rotted frames, lead paint, or structural damage may require additional prep work before installation.
Story & Access
Second and third floor windows may need scaffolding or lift equipment, which can add to installation costs.
