Yes — Windham is one of our active service areas. We work on residential properties throughout town, from the larger colonials and newer construction off Route 111 to the wooded lots tucked back on private roads. Windham homes tend to be well-maintained, which is exactly why homeowners here notice when algae starts creeping up the siding or the driveway starts looking grey and tired. We know this area, we know the property types, and we're familiar with what southern NH winters do to exteriors down here near the Massachusetts border.

This is probably the most common call we get from Windham. The green is algae, and the dark streaking is usually a bacteria called gloeocapsa magma. Both thrive in shaded, damp conditions — and Windham's wooded lots mean a lot of homes have north-facing or tree-shaded walls that stay damp longer than they should after rain. It's not a reflection of how well you maintain your home. It's just what happens when you're surrounded by trees in New Hampshire. The fix is soft washing — low-pressure application of a biodegradable cleaning solution that kills the growth at the root rather than just blasting the surface layer off temporarily.

Pricing depends on what you need done — a single driveway is a different job from a full house wash on a 3,000 sq ft colonial with a deck and walkways. Windham homes tend to be larger than average, so we look at the actual square footage and surface types before quoting anything. What you won't get from us is a suspiciously low number on the phone that climbs once we're on-site. We give you a real, fixed price upfront. If anything changes mid-job, we talk to you before we do anything. No surprises on the invoice — that's just how we work.

This is the right question to ask — and honestly, some contractors do cause damage by using too much pressure on the wrong surfaces. High pressure on vinyl siding can crack panels and drive water into wall cavities. On wood, it lifts grain and damages paint. That's why we don't use high pressure on siding or roofing — we soft wash those surfaces. High pressure stays on concrete, brick, and stone where it belongs. As for landscaping, we wet down plants and shrubs before we start and rinse them after. Windham properties usually have mature, established gardens that we take care to work around properly.

Usually it's a mix of algae, oxidation, and embedded road salt residue from New Hampshire winters. Windham driveways that are partially shaded — which is a lot of them, given how wooded the town is — stay damp long enough after rain for algae to anchor in and spread. A garden hose won't touch it because the growth is embedded into the concrete surface, not just sitting on top. We treat the surface with the right cleaning solution first, then pressure wash it out properly. Most Windham homeowners are genuinely surprised how much lighter their driveway looks when it's done — it makes the whole front of the property look different.

Spring is the most popular window for Windham homeowners — typically late April through June, once temperatures are holding above 50°F. After a New Hampshire winter, there's a full season of road salt residue, sand, and organic debris sitting on driveways, walkways, and siding. Getting it off early in the season stops it from working deeper into surfaces through the warmer months. A lot of Windham homeowners also do a second clean in October — after the leaves have dropped but before the ground freezes — specifically to clear gutters and prevent mold and organic staining from sitting on surfaces all winter. Two cleans a year is usually enough to stay on top of it without overdoing it.

Fully licensed and insured — $2 million in general liability coverage on every job we do in Windham. Windham homeowners tend to ask this upfront, and they're right to. The properties here represent serious investment, and the last thing you want is an uninsured contractor on your roof or driveway with no recourse if something gets damaged. We'll hand over proof of insurance before we start without any hesitation. We'd actually encourage you to ask every contractor you're considering for the same — anyone who's legitimate will give it to you immediately, and anyone who hedges on that question is worth walking away from.
