Why concrete needs professional cleaning
Concrete is porous, which means algae, mold, mildew, and mineral staining work their way into the surface rather than sitting on top of it. A garden hose won't touch it — you need the right combination of pressure and cleaning chemistry to pull the contamination out of the pores. Left untreated, biological growth makes concrete slippery and causes surface degradation over time.
Pool decks are particularly important to keep clean. Wet algae around a pool is a serious slip hazard, and the combination of splash water, sunscreen, and organic debris creates ideal conditions for growth. We recommend cleaning pool decks every spring before the season opens.
Our process
We use surface cleaning equipment specifically designed for flat concrete — spinning heads that deliver uniform pressure across the entire surface, avoiding the streaking and uneven cleaning that comes from a standard pressure washing wand. For oil stains and heavy organic buildup, we pre-treat with professional degreasing and cleaning solutions before washing. We can also apply a post-wash inhibitor treatment to slow future algae and moss growth on shaded or damp surfaces.
Concrete cleaning cost in NH
Most concrete cleaning jobs run $150–$400 depending on the total square footage and condition of the surface. Pool decks, large patios, or surfaces with significant oil staining or moss growth may fall at the higher end. Free estimates are always provided before any work begins.
