What Boulder, CO Homeowners Ask About Window Replacement
Here’s what Boulder homeowners want to know before they get started, with answers to each question.
It depends on the window. Any exterior change to a Boulder landmark or historic-district home needs a Landmark Alteration Certificate before the building permit, and the city’s worksheet allows only repair of its most important windows. On front elevations, even “important” windows are repair-only. Homes outside those districts don’t face these limits.
Not right now. Boulder County’s EnergySmart program dropped its standard rebates for 2026 and now offers only income-qualified rebates, and windows and doors aren’t eligible. Xcel Energy’s residential rebates exclude windows too. Your free estimate gives you one exact price to plan around.
Boulder’s record gust is 147 mph, from 1971, and the January 1982 windstorm hit 137 mph at NCAR’s Table Mesa site. The city has seen at least 16 storms with gusts over 100 mph since 1967. A tight, professional installation that keeps out wind-driven dust and rain matters as much as the window itself. Ask us about design pressure ratings.
