Deck Cleaning in Northern Virginia

Decks in Northern Virginia sit under trees, collect leaves and stay damp for days after a storm. That is a recipe for green, slippery boards and black mildew spots. NovaBlastWash deck cleaning removes the buildup using methods matched to your decking.

Which decks can be cleaned?

• Pressure-treated pine — the most common deck material in the area
• Cedar and other softwoods — cleaned very gently
• Composite and PVC decking — cleaned according to manufacturer guidance

Some decks are not good candidates for cleaning alone: boards that are rotting or soft, or stain that is badly peeling and needs stripping. If that sounds like your deck, mention it and we will talk through what makes sense.

Why pressure matters on decks

Too much pressure on wood causes "furring" — raised, fuzzy wood fibers — along with gouges and wand marks that show through new stain. Proper deck cleaning relies on low pressure and appropriate cleaning solutions to lift mildew and grime, then a careful rinse. Composite decks are even more sensitive to aggressive methods.

What deck cleaning covers

• Deck boards and stair treads
• Railings, balusters and post caps
• Lattice, privacy screens and built-in benches
• Pergolas and other attached structures, where accessible

Cleaning before staining or sealing

Stain and sealer only perform well on clean wood. Cleaning first removes mildew, dirt and loose fibers so new stain can penetrate evenly. After cleaning, let the wood dry completely — typically at least a couple of dry days — and follow your stain manufacturer's directions before applying anything.
