Durham's exterior cleaning challenges: shade and moisture
Durham is one of the more heavily wooded towns we serve. Properties throughout town — particularly those near the Oyster River and along Faculty Road and Madbury Road — sit under dense tree canopy that keeps siding and roofs damp long after rain. North-facing walls in Durham can develop visible green and black algae growth within a single season. The combination of shade, humidity, and organic debris (pine needles, leaf buildup in gutters) makes annual soft washing and gutter cleaning particularly important for Durham homeowners who want to protect their siding and roofing investment.
When to schedule in Durham
Spring is our busiest season in Durham — many homeowners schedule in April or May after the winter runoff season reveals the extent of the year's algae and mold growth. Fall is the other key window: Durham's heavy tree coverage means significant leaf accumulation in gutters, making October–November the right time for a thorough gutter flush before winter. We serve Durham regularly and can typically schedule within 1–2 weeks outside of peak spring season.
