Why Your Deck Looks the Way It Does

In North Carolina's humid climate, decks don't just get dirty — they accumulate multiple overlapping problems. Green algae grows in shaded areas and along board gaps. Black mold develops on the surface and works into the grain on wood decks. UV exposure causes gray weathering and bleaching. And pollen, leaf tannins, and moisture cycling lock all of it in.

The most important thing we assess before any deck job is the material. Composite and Trex decks require low-pressure soft washing — high pressure on composite creates visible strand damage, fuzzing, and voided manufacturer warranties. Wood decks — pressure-treated, cedar, pine — can handle more pressure, but need the right chemistry to lift embedded mold without bleaching the wood unevenly.

We identify your deck material before we quote and before we touch it. The right method for your deck is built into the job from the start — not guessed at on the day of service.

Deck Cleaning — Frequently Asked Questions

Can you clean composite or Trex decks without damaging them?
Yes — but only with the right method. Composite decking including Trex, TimberTech, and Azek requires low-pressure soft washing, not standard power washing. High pressure on composite creates surface damage: visible strand fuzzing, board scarring, and in severe cases, delamination. We always identify composite decking before quoting and use a low-pressure approach with appropriate cleaning solutions that remove mold and algae without physical damage to the board surface. Manufacturer warranties are preserved.
How do you remove green algae from a wood deck?
Green algae on wood decks requires a combination of chemistry and appropriate pressure. We apply a biodegradable algaecide solution that breaks down the algae at the cellular level, dwell time allows it to penetrate into the grain, and then we rinse with controlled pressure that clears the dead algae without raising the grain or creating surface furring. The result is uniform — no blotchy bleached patches — and the deck is ready for staining or sealing once it has dried.
Should I stain my deck after you clean it?
For bare wood or previously stained decks where the stain is worn, cleaning followed by staining or sealing is highly recommended. Cleaning removes the contaminants that prevent stain adhesion and opens the wood grain for better penetration. Timing matters: wood decks should dry for at least 48–72 hours after cleaning before staining, depending on weather. If staining is the plan, mention it when you call — we can discuss surface prep that specifically optimizes for stain absorption.
How often should a deck be cleaned in North Carolina?
In NC's humid climate, most wood decks benefit from annual cleaning — especially if they're shaded or near tree coverage. Composite decks typically need cleaning every 1–2 years depending on debris and algae growth. Pool decks may need more frequent attention due to water splash and chemical runoff. If you can see green growth or the deck surface feels slippery when wet, it's time. We'll tell you what we see and recommend a schedule based on your specific deck at the time of estimate.
Do you clean docks?
Yes. We service dock decking throughout the Lake Hickory area and surrounding waterfront properties in Catawba County. Dock decking — especially pressure-treated and composite in waterfront environments — accumulates algae, lake sediment, and biological growth faster than land decks due to constant moisture exposure. We use methods appropriate for dock materials and are careful with runoff management near waterways.
