Deck & Fence Cleaning

Wood is where DIY pressure washing goes wrong most often. Too much pressure fuzzes the fibers, carves lap marks into deck boards, and shreds the surface of cedar pickets. But left alone, a deck in our climate goes gray, grows slick mildew, and rots years early.

We clean wood the way it needs: the right detergent to kill growth and lift the gray, gentle pressure to rinse, and a finish that’s smooth enough to walk barefoot — or to take stain evenly, if that’s the next step.

Sound familiar?

Signs it's time

If any of these describe your place, a wash will make a bigger difference than you'd think.

  • A deck that’s turned gray or green and feels slick when wet
  • Mildew spots across composite decking (Trex and similar)
  • A fence that’s lost its color and looks weathered out
  • Prepping to stain or seal and needing genuinely clean wood first
  • Mold creeping up shaded porch posts and railings

Our approach

Wood-safe means chemistry first, pressure second

We apply a wood-safe cleaner that breaks down mildew and the gray, dead surface fibers, then rinse with wide-fan, low-pressure passes moving with the grain. No gouges, no fuzzing, no lap marks.

Composite decking gets its own treatment — manufacturers void warranties over high pressure, so we keep it gentle and let the detergent handle the mildew that grows in the texture.

If you’re planning to stain or seal afterward, tell us — we’ll finish with a brightener that opens the grain and evens the tone so the stain takes beautifully.

What's included

  • Deck boards, railings, spindles, stairs, and skirting
  • Fence lines — both sides where access allows
  • Wood-safe detergents matched to the material (pine, cedar, composite)
  • Optional wood brightener prep for staining projects
  • Furniture moved and replaced, surrounding plants rinsed

What affects the price

Every property is different, so we quote each one individually — free, fast, and with no obligation. These are the things that move the number:

  • Deck or fence square footage (fences priced by linear foot)
  • Material — softwoods and composites need slower, gentler work
  • Condition, and whether stain-prep brightening is included

FAQs

Deck & Fence Cleaning questions

Can you clean a deck without ruining the wood?

Yes — that’s the whole point of how we do it. Detergents do the killing and lifting; low, wide-fan pressure just rinses. The damage you’ve seen on other decks comes from high pressure used as a substitute for chemistry.

Is it safe for composite decking like Trex?

Yes. We use low pressure and cleaners appropriate for composite, which is exactly what the manufacturers call for. High pressure on composite can void the warranty — we stay well clear of that.

How soon after cleaning can I stain?

Give the wood two to three dry days after our brightener prep. Clean, dry, open-grained wood is the difference between stain that lasts and stain that peels.

Will my plants along the fence line be okay?

Yes — same protection as every job: pre-wet before, rinse after, and cleaners diluted to plant-safe levels.

While we're there, we can also handle…

Bundling services in one visit is the cheapest way to do this — one setup, one trip charge, better price per surface.
