New Hampshire winters are rough on wood. Freeze, thaw, wet, dry — by spring most decks in Rochester are gray, slippery, and growing things they shouldn't be. A proper deck cleaning removes all of it: mold, algae, tannin stains, and surface graying.
If you're planning to stain or seal, we get the deck ready. Clean wood absorbs stain evenly and lasts years longer than stain applied to a dirty surface. If you just want a clean deck to use this summer, same process — just stop there.
Algae and mold on deck boards turn slippery when wet. That's a hazard for kids, guests, and anyone using stairs. Cleaning it isn't just cosmetic — it's a safety issue.
Mold and moisture work into the grain over time and accelerate rot. Regular cleaning adds years to the life of the wood and pushes off the cost of replacement.
If you're planning to stain, cleaning is non-negotiable. Stain applied over algae, mold, or old failing stain won't adhere properly and will peel. Clean it first. Then stain.
You paid for that deck. A gray, stained surface you avoid using in the summer is a waste. One afternoon of cleaning gets you back out there.
We check for loose boards, protruding fasteners, soft spots, and areas of concern. We'll let you know what we find before we start cleaning.
A biodegradable deck cleaner is applied to the full surface. It breaks down mold, algae, surface oxidation, and old tannin stains before we add any water pressure.
We use the right pressure and tip for the surface type. Wood gets lower pressure to avoid grain raise. Composite gets even lower. No gouging, no splintering.
After cleaning, we let you know the dry time before staining — usually 48–72 hours. The surface is open, clean, and ready to accept stain evenly.
Tell us about your deck and we'll send a price — usually within a few hours.
