Deck Cleaning & Pressure Washing
Deck-specific cleaning that lifts mildew, algae and gray weathering without damaging wood fibers or composite surfaces.
Cleaning Done Right, Not Just Fast
Plenty of companies advertise a cheap, $99 "blast-and-go" pressure wash — but generic high pressure on the wrong setting can strip wood fibers and drive water into seams it shouldn't reach. We do it differently: deck-specific cleaning products and controlled pressure — generally 1,500 to 3,000 PSI through a 25° or 40° nozzle for wood surfaces — to lift mildew, algae and gray weathering safely, whether it's a wood deck, a Trex composite deck, a fence, or a boat dock.
Every deck gets tested on a small, inconspicuous area first, and we never let the wand sit in one spot long enough to gouge the wood. Once the surface is clean, we rinse away all soap and cleaner residue and let the deck dry completely before any sealant or stain goes down — skipping that drying step is one of the most common reasons a fresh coat of stain fails within a year.
Composite and Trex decking needs an entirely different approach than wood. Early-generation composite without a protective cap can mildew and stain if it isn't cleaned semi-annually, while newer high-performance Trex lines like Transcend, Enhance and Lineage generally only need soap and water or a gentle wash. In every case, excessive pressure can damage uncapped composite boards, so we adjust our pressure and technique to the specific material we're working on.
