Sonlight Window Cleaning serves Fort Collins and Northern Colorado with professional residential and commercial window cleaning. Since 1978, our 350+ five-star reviews speak for our reputation across Old Town, the foothills, and every neighborhood in between.
Fort Collins combines the old and the new like few Colorado cities — Victorian-era homes near CSU sit a mile from new construction in Timnath. The Cache la Poudre runs through the city, and the foothills push high winds and pine pollen into every west-facing window from late March through June.
Our crew has worked every part of FoCo — the historic homes off Mountain Avenue and Mulberry, the bungalow-belt off Plum and Stuart, the larger lots along Horsetooth, and the master-planned communities in Timnath, Wellington, and Windsor. We treat a 1903 Old Town foursquare with the same care as a 2024 Bucking Horse new build.
Sonlight Fort Collins services include interior + exterior window cleaning, screen removal and cleaning, gutter cleaning, pressure washing, soft wash, and solar-panel cleaning. We carry $2M general liability + workers' comp and back every job with a 24-hour satisfaction guarantee.

Spring foothill winds drop yellow pine pollen on every Fort Collins window from late March through May. Heavy pollen years can re-coat a freshly cleaned window in 48 hours. We schedule major FoCo cleans for late May after pollen drops.
Mid-June cottonwood fluff sticks to window glass and screens. Cleans done before fluff drop are short-lived; we usually wait until mid-to-late June for residential clusters.
Northern Colorado is hail country. After a major storm we run a separate post-storm queue for owners cleaning up before insurance walkthroughs. Same-week service is standard.
We've worked every part of Fort Collins — here's what to expect in your area.
Late-1800s Victorian and Queen Anne homes; we hand-clean original glass and never use power tools on antique frames.
Mature trees mean heavy spring pollen on east-facing windows; late-May cleans are the cleanest of the year.
Bungalow-belt homes with original wood storms; we strip and rebed each spring.
New construction with modern wide casements — full-service cleans average 35-50 panes.
Larger lots near the foothills; high winds bring fine red dust onto west-facing exposures.
Master-planned communities with HOAs we coordinate with directly for recurring service.
Mix of older farmhouses and new builds; pollen + wind are the dominant cleaning factors.
Strong tornado/hail country — post-storm cleaning is common before insurance inspections.
Rentals and student housing; fast move-in/move-out service for property managers.
Mountain-foothill transition; large windows facing east toward town.
