I recently had my house washed by an amazing service in Calvert County, and I couldn't be happier with the results! The team was professional, punctual, and did a fantastic job making my home look brand new. If you're in the area and need a house wash, I highly recommend them!

Why We Stand Out

What Deck Washing Removes

Our deck cleaning removes algae, mildew, pollen, dirt and organic buildup that can make outdoor surfaces look weathered or feel slippery. We adjust the cleaning method for wood and composite decking.

Wood and Composite Deck Care

Wood, composite and painted deck surfaces do not all tolerate the same pressure. We inspect the material and condition first, then use surface-appropriate cleaners, pressure and rinsing to protect the finish.

Our Deck Cleaning Process

We inspect the deck, identify problem areas, apply the appropriate treatment, clean the boards and railings included in the quote, rinse thoroughly and review the results with you.

Why Choose 
Restore Exterior?

Can Pressure Washing Damage a Deck?

Too much pressure or an incorrect tip can mark wood and damage coatings. Professional deck washing uses controlled pressure and the right cleaning solution for the surface instead of relying on force alone.

When Should a Deck Be Cleaned?

Consider cleaning when algae, mildew, dark buildup or slippery areas appear, or before staining or sealing. The best schedule depends on shade, trees, moisture and how heavily the deck is used.

Preparing for Deck Cleaning

Before service, remove small furniture, grills and fragile items when possible. Tell us about loose boards, peeling stain, electrical concerns or areas you want excluded so we can plan the work safely.
