ProVia Endure Vinyl Replacement Windows
The Endure is the vinyl window we chose for Denver homes after comparing the category: a welded frame and sash, Innergy thermal reinforcements instead of heat-leaking aluminum, foam-insulated frame chambers, and ComforTech insulated glass with an all-foam Super Spacer that resists the seal failure that fogs lesser windows by year eight. Every unit is built to order in Ohio for your exact openings and backed by a lifetime transferable warranty that covers the frame, the hardware, the glass seal, and even glass breakage.
Built for Colorado, Priced for Real Budgets
Denver punishes windows: 60-degree temperature swings, hard UV at altitude, and hail. The Endure's reinforced, insulated frame is engineered for exactly those conditions, and it meets Colorado's 2026 window energy efficiency requirements in the packages we quote. Most Denver homeowners pay $1450 to $2,500 per window installed, with exact written pricing provided in one free in-home visit.
Every Style Your Home Needs
The Endure family covers double hung, single hung, sliding, casement, awning, bay, bow, and picture windows, plus specialty shapes, so a whole-house project can carry one consistent look. Replacing a patio door too? See our ProVia patio doors.
