A gray, mildewed deck is not a sign that the wood is finished. It is almost always just dirty. The Hydro Bros deck wash uses a deck-safe cleaning solution at low pressure so the algae, mildew, and graying lift cleanly and the wood grain stays intact. No fuzzed-out boards, no zebra stripes, no shredded finish.
What you get with a Hydro Bros deck wash
- Soft-wash cleaning solution sized to wood or composite.
- Low-pressure rinse that protects the wood grain.
- Spindles, railings, stair treads, and underside detailed by hand.
- Pre-wet landscaping and rinsed throughout the job.
- Before-and-after photos sent the same day.
- Flat-rate quote up front, no add-ons at the truck.
Why soft wash, not pressure wash
High-pressure water on wood does three things you do not want. It raises the grain so the boards feel fuzzy. It gouges softer cedar and pine where the wand stays in one spot too long. And it strips old stain or sealer unevenly, which means your refinishing job starts with a sanding pass that should not have been necessary.
A real soft wash uses a biodegradable cleaning solution that kills the algae and mildew at the root. The low-pressure rinse carries it off without touching the wood grain. The deck ends up cleaner, smoother, and ready for stain or sealer if you are planning to refinish.
What we wash on every deck
- Cedar: soft wash only. Cedar fuzzes fast under high pressure.
- Pressure-treated lumber: the most common Long Island deck, cleans up dramatically.
- Mahogany and ipe: careful dilution to protect the natural oils.
- Composite (Trex, TimberTech, AZEK): composite-specific chemistry, no direct wand pressure.
- Railings and spindles: hand-detailed so the vertical surfaces match the deck boards.
- Stairs and stringers: walked individually with attention to the front edge of each tread.
The Hydro Bros deck wash process
Every wash starts with a walk-around. We move planters, pre-wet the landscaping, and check the wood for any soft spots that need a lighter touch. Then the cleaning solution goes on, dwells for a few minutes, and the deck gets a low-pressure rinse from one end to the other. Spindles, railings, stair treads, and the underside of the deck all get detailed by hand.
Most decks take two to four hours. After the rinse, the deck needs 24 to 48 hours to dry before refinishing. If you are planning to stain or seal, we will give you a clean dry surface to work from.
