Why driveways need professional cleaning
Your driveway takes constant punishment — vehicle traffic, oil drips, road salt, winter sand, moss, and algae all leave their mark. Over time, algae and moss growth creates slippery surfaces that are a safety hazard — especially in NH winters when wet growth freezes overnight.

- Asphalt driveways

Our process
We use surface cleaning equipment designed specifically for flat concrete — delivering consistent, streak-free results across the entire surface. For oil stains and heavy contamination, we pre-treat with professional degreasing solutions before pressure washing. We can also apply post-wash inhibitor treatments to slow future algae and moss growth.
Where we serve
We serve Portsmouth, Exeter, Dover, Durham, Hampton, Stratham, Lee, Nottingham, Barrington, Rye, Newmarket, and surrounding areas, as well as Southern Maine and the NH Lakes Region.
Driveway cleaning cost in NH
Most residential driveway cleanings in NH run $150–$350 depending on size, material, and condition. Driveways with heavy oil staining, extensive moss growth, or that haven't been cleaned in years may fall at the higher end. Free estimates are always provided before any work begins — pricing is based on your specific surface, not a one-size-fits-all rate.
Road salt and NH driveways
NH roads are heavily salted from November through April, and that salt tracks onto your driveway with every vehicle. Over time, road salt accelerates concrete spalling, stains asphalt, and leaves a white mineral residue that builds up season after season. Spring cleaning flushes that salt and sand before it has a full summer to work deeper into the surface. It's also the best time to assess whether any crack sealing or sealing is warranted before another winter.
