Deck Cleaning
Restore your deck's natural beauty safely and effectively — without the damage that high pressure washing causes to wood surfaces.
Professional Deck Cleaning in Baltimore
Your deck takes more abuse than almost any other surface around your home. Constant exposure to sun, rain, foot traffic, and organic debris causes wood to grey, darken, and develop mold and mildew that makes surfaces slippery and unappealing. Without regular cleaning, that organic growth penetrates deep into the wood grain — accelerating rot and dramatically shortening the life of your deck.
Renewal Pressure Washing uses low pressure soft wash techniques specifically designed for wood and composite deck surfaces — removing years of dirt, mold, and algae buildup without raising the grain, causing splintering, or stripping your existing stain or sealant.
How We Clean Every Deck Type
Pressure Treated Wood
Pressure treated lumber is the most common deck material in Baltimore — but it's also prone to greying, mold growth, and tannin staining. We use a wood-safe brightening solution that restores the natural color of treated lumber while killing organic growth at the root.
Cedar & Redwood
Cedar and redwood are naturally resistant to rot but still develop surface mold, algae, and grey weathering over time. These premium wood species require lower pressure and more diluted cleaning solutions to preserve their natural oils and prevent damage to the wood fibers.
Composite Decking
Composite decking like Trex and TimberTech is low maintenance but not maintenance free — it develops algae, mold, and organic staining between the boards and on the surface. We use composite-safe cleaning solutions and low pressure to clean without voiding manufacturer warranties.
Painted & Stained Surfaces
Painted and stained deck surfaces require careful pressure control to clean without lifting or stripping the existing finish. We assess the adhesion and condition of the paint or stain before we start and adjust our approach to preserve as much of the existing finish as possible.

Our Deck Cleaning Process
Deck Assessment
We inspect the deck material, existing finish condition, and areas of concern before we start — identifying any rot, loose boards, or structural issues we notice during the assessment.
Furniture & Plant Protection
All deck furniture is moved and surrounding plants and landscaping are pre-wetted to protect them from cleaning solution contact.
Cleaning Solution Application
A wood-safe or composite-safe cleaning solution is applied to the entire deck surface and allowed to dwell — penetrating the wood grain to kill mold and algae at the root.
Low Pressure Soft Wash Rinse
The entire deck is rinsed at low pressure to remove the cleaning solution along with all loosened dirt, mold, and organic debris — without raising the wood grain or damaging the surface.
Final Inspection
We walk the deck with you to inspect every board and railing before we leave. We'll also advise on the best time to apply a new sealant or stain if needed.
