Pool Deck & Patio Cleaning in Seacoast, NH

The area around your pool gets slick and grimy fast. We clean it back to a safe, bright surface for the season.

The concrete and stone around a pool is a magnet for algae, sunscreen film, and organic buildup, and once it gets slick it stops being safe for bare feet. Black Diamond cleans pool decks and patios back to a bright, grippy surface so the space is ready to actually use.

Cleaner and safer

Algae and slime around a pool are a real slip hazard. We clear the growth from the deck, coping, and surrounding patio, and treat the seams and shady spots where it takes hold first. The surface comes back lighter and far less slippery.

Every surface around the water

Stamped and poured concrete, pavers, travertine, flagstone, and brick. We match the pressure and cleaner to the material so nothing gets etched or dulled, which matters a lot on softer stone like travertine.

Timed for the season, fully insured

Book it ahead of opening the pool and the whole space is ready for the first warm weekend. Connor and Gabe handle it directly, fully insured, with free quotes usually scheduled the same week.
