Lafayette sits in eastern Boulder County at roughly 5,200 feet, out where the foothills give way to the open plains, which means your windows take a beating from both directions. High-altitude UV fades interiors and breaks down old seals faster than at lower elevations, while the big day-to-night temperature swings common up here drive the heating and cooling bills that single-pane and failing double-pane windows let escape. Add the downslope winds that push off the mountains and the hail that tracks across town in spring and summer, and the windows on an exposed Lafayette home work harder than most.

That is why CR Custom Exteriors installs energy-efficient replacement windows built specifically for these conditions. Whether you own a historic home near Old Town Lafayette, a newer build in Indian Peaks or Blue Heron, or an established place in Centaur Village or Waneka Landing, we fit double- and triple-pane, Low-E, argon-filled windows with frame options in vinyl, fiberglass, and composite. As a family-owned company with 10+ years on the Front Range, we are licensed, insured, and handle manufacturer-spec installation, proper flashing, and egress compliance so your windows seal tight, hold up to the weather, and lower your bills.

Common questions

Which replacement windows are best for Lafayette's climate?
For Lafayette's high-altitude UV and big temperature swings, we recommend Low-E, argon-filled windows in double- or triple-pane. Triple-pane adds extra insulation and noise control for homes exposed to downslope wind off the foothills, while Low-E coatings protect interiors from fading. We help you choose the right glass and frame for your home and budget.
What frame material should I choose for my Lafayette home?
We offer vinyl, fiberglass, and composite frames. Vinyl is the most budget-friendly and low-maintenance, fiberglass handles Lafayette's freeze-thaw and temperature swings with very little expansion, and composite blends durability with a premium look that suits Old Town Lafayette's character homes. We walk you through the trade-offs during your free estimate.
What affects the cost of replacement windows in Lafayette?
Cost depends on the number and size of windows, your glass package (double- versus triple-pane and Low-E options), frame material, and whether openings need egress upgrades or flashing repairs. Every Lafayette homeowner gets a free, detailed estimate up front, with manufacturer-spec installation and warranty coverage included.
