Our Cleaning Process

Safe & Effective Deck Cleaning

Deck surfaces require proper care and cleaning to avoid unnecessary damage. Using excessive pressure on wood or composite materials can leave surfaces splintered, streaked, or prematurely worn.


At Dharma Surface Cleaning, we use professional soft washing and surface cleaning methods tailored to the condition and material of your deck.

Our process safely removes:


  • Dirt and grime
  • Algae and mildew
  • Organic buildup
  • Surface stains
  • Weather discoloration


Our goal is to restore the appearance of your deck while helping preserve the material underneath.

Featured Project Restorations

Wood plank showing mildew, graying, fading, cracking, warping, splintering, UV damage, nail popping, cupping

For the Love of Wood!

Wood must be protected and nourished. When the elements have stripped it of its natural oils, then we must replace those oils to prevent further damage. Restoring wood costs pennies on the dollar when compared to the cost of replacement. Click here for a thorough discussion of the factors governing deck finish product performance.

Cleaning a wood surface

Cleaning a wood surface with the proper detergents is what produces the desired results. Without the proper solutions the novice is prone to rely too much on pressure alone, which will damage the wood grain, never fully restore the wood's natural beauty and the results will be short-lived.

This unique hardwood deck in Nantasket

This unique hardwood deck in Nantasket, MA was restored beautifully. It required some paint stripping, our normal approach PLUS some creative use of brighteners. This is perfect example of the need for the proper solutions and knowledge of how to use them.

This gorgeous New Jersey cedar shake roof​

This gorgeous New Jersey cedar shake roof was hiding under 30 years of moss and lichen growth. There were even tree frogs living up here! The cedar was, for the most part, in surprisingly good shape under the decades o lichen and moss. A preservative was then applied, once the surface was dry, to seal out further encroachment. It's never too late to stop the decay and protect your investment.​
