Can you clean composite decks, or just wood?

We clean both wood and composite decks. The method differs slightly — composite requires lower pressure and specific cleaners to avoid surface damage — but both come out looking significantly better. We'll tell you exactly what we're going to do before we start.

How long after cleaning can I stain or seal my deck?

Typically 48 to 72 hours for wood to fully dry before staining, depending on weather. We'll let you know the right window when we finish. Don't rush it — staining wet wood wastes money.

Will pressure washing damage my deck boards?

Done wrong, yes — a consumer machine on a fan tip can raise the grain and splinter old wood. We use the correct pressure and tip for the surface type. Worn or rotted boards won't survive any washing, and we'll point those out before we start.

Can you clean my fence at the same time as the deck?

Yes. Fence cleaning pairs well with deck cleaning and we can quote both together. Wood fences get the same treatment — cleaned, brightened, and ready to stain if that's the plan.

How often should I clean my deck?

Annual cleaning is ideal for New Hampshire decks. Wet winters and spring moisture create perfect conditions for mold and algae growth. If you're seeing green or gray, it's time. Don't wait until it's slippery.

Deck Cleaning That Brings Wood Back to Life

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.

Why It Matters

A Dirty Deck Costs More Than You Think

Slippery Decks Are a Liability

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.

Extends the Life of the Wood

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.

Stain Won't Stick to a Dirty Deck

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.

Your Backyard Should Be Usable

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.

How It Works

From Weathered to Ready.

Inspect the Surface

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.

Apply Cleaning Solution

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.

Controlled Pressure Wash

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.

Dry & Stain-Ready

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.

Usually not. We've brought back decks that homeowners assumed needed full replacement. If the boards are structurally sound, a proper clean and stain will extend the life significantly and cost a fraction of new decking. Send us a photo and we'll give you a straight answer.
