Local Expertise for Longmont Homes

Longmont sits at the edge of the Front Range foothills and the St. Vrain Valley, where strong downslope winds and hail from summer storms are a recurring challenge for exterior paint and caulking. Homes in the historic downtown neighborhoods near Main Street and the Prospect New Town development both see UV-driven fade on south-facing siding, while older homes in the Kimbark Street corridor often have original wood trim that needs thorough scraping and priming before a new coat will hold.
