Deck Cleaning in the Quad Cities, IL & IA
Low-pressure, wood-safe cleaning that lifts grey weathering and green film without furring the boards or carving lines into the grain.
Decks are the easiest surface to ruin
Wood is soft, and high pressure does not clean it so much as erode it. Push a wand too close to a cedar or pine deck and you shred the soft summer growth between the grain lines, leaving a fuzzy, splintered surface that looks worse than the dirt did and will not take stain evenly. Those marks do not sand out easily.
So the pressure comes down and the cleaning solution does the work. A wood-appropriate cleaner is applied, allowed to dwell and break down the grey oxidized layer and the algae in the grain, then rinsed at low pressure with the boards. Grey weathering lifts, the wood tone comes back, and the surface stays smooth.
Composite boards get the same treatment for a different reason. Trex, TimberTech and similar surfaces build up a film of mold and mildew in the embossed grain, and most manufacturers explicitly prohibit high pressure. Chemical cleaning and a rinse is the approved method.
The full deck, not just the floor
- Deck boards, cleaned with the grain
- Railings, balusters, posts and caps
- Stairs, stringers and the landing
- The underside of the rail and the skirt board where growth hides
- The wall and siding behind the deck, rinsed as part of the job
- Furniture moved and put back where it was
Cleaning before staining
If you are staining or sealing this season, the cleaning is not optional prep — it is most of the job. Stain applied over a grey oxidized layer or over mildew bonds to the dirt instead of the wood, and it peels within a season.
The other half is drying time. Wood needs roughly forty-eight hours of dry weather after washing before it will take stain properly, longer if the deck is shaded or the humidity stays up. Book the cleaning with that window in mind and the stain will last years instead of months.

Pricing
Quote-only, and firm. Price depends on the size of the home, access, and the condition of the surface, so instead of publishing a starting-at number that changes the moment we see the property, we look at the actual job and give you a fixed price before any work begins. No hourly meter, and the number we quote is the number you pay. Call (309) 507-6816 — most homes can be quoted in one conversation.

Deck Cleaning questions we get
- Will pressure washing damage my deck?
- High pressure will, which is why we do not use it on wood. We clean chemically at low pressure and rinse with the grain. The fuzzy, striped look on so many decks is pressure damage, and it is permanent.
- How long should I wait before staining?
- About forty-eight hours of dry weather for most decks, longer if it is shaded or humid. Staining damp wood traps moisture and the finish fails early.
- Can you clean composite decking?
- Yes, and the method matters more there than on wood. Composite manufacturers prohibit high pressure; the approved approach is a cleaning solution with dwell time and a gentle rinse, which is what we do.
- Do you move the furniture?
- Yes. Furniture, grills and planters get moved off, the deck is cleaned, and everything goes back roughly where it started.
