Deck Cleaning

Cleaning for wood, composite, and other deck surfaces.

Starting at $149

Our Process

1. Inspect Material & Condition. We inspect the deck material and condition before starting.

2. Clear Furnishings. Accessible furnishings are cleared from the deck.

3. Surface-Appropriate Treatment. We apply a surface-appropriate treatment at a pressure suited to the decking material.

4. Thorough Rinse. We rinse thoroughly.

Why it matters: Wood and composite decking respond very differently to pressure. Matching the technique to the decking material is what protects the surface while still removing buildup.

Common Questions

How do you clean a wood or composite deck without damaging it?

Decks are cleaned with a surface-appropriate solution and controlled pressure suited to the decking material, not the pressure used on concrete. Wood is worked with the grain so boards aren’t furred or gouged, and composite is cleaned with a low-pressure wash and solution so the embossed surface isn’t scarred. We inspect boards, railings, and fasteners first and clear accessible furnishings before starting, and we point out any soft or failing boards we find.

What is the difference between soft washing and pressure washing?

Soft washing uses low pressure and surface-appropriate cleaning solutions for delicate materials such as many roofs and siding types. Pressure washing is generally reserved for durable hard surfaces, such as applicable concrete. SurfaceWorks ProWash selects the method based on the material, condition, and project scope.

Will pressure washing remove that chalky residue or fix oxidized siding?

No. Washing removes dirt, pollen, and organic growth sitting on the siding, but oxidation is the siding's own surface layer breaking down, not something sitting on top of it. On siding that's already chalked unevenly, an aggressive wash can lift some of that loose surface film and not the rest, leaving it looking blotchier than before. Our standard wash uses a controlled, low-pressure approach so it cleans evenly without making existing oxidation worse. Restoring color under the chalk is a separate, optional treatment we offer on request.

Will soft washing damage my roof shingles or siding?

Soft washing uses low pressure and a solution matched to the material, which is why it is the recommended method for shingles, painted wood, vinyl, and other surfaces that high pressure can damage. Concentration, dwell time, and rinse approach are adjusted to the surface and its condition rather than applied the same way everywhere.

Do you clean paver and stamped-concrete patios?

Yes. Patios are cleaned at a pressure matched to the material, which for pavers and stamped or decorative concrete means a gentler approach than a plain utility slab. On pavers we work in controlled passes to limit how much joint sand is disturbed, and we tell you if joints will need re-sanding afterward. Sealing is available as a follow-up once the surface is clean and dry.

Can brick and masonry be cleaned without damaging the mortar?

Yes, when the pressure is kept off it. Brick, block, and stone are cleaned with a low-pressure application and a solution appropriate to masonry, because aged or soft mortar joints erode under pressure that modern concrete shrugs off. We check joint condition, prior coatings or paint, and window and door openings first, and test an inconspicuous area when the material is uncertain. Where joints are already failing, we tell you that cleaning will reveal it rather than hide it.

Can faded color on oxidized siding be brought back?

Often yes, as an optional treatment separate from a standard wash. A house wash removes the dirt and organic growth sitting on the siding; restoring color means treating the oxidized surface layer itself, which is a different product and a different process. How much comes back depends on how far the oxidation has progressed and how evenly the panel has chalked, and heavily degraded siding can improve without returning to its original color. We look at the siding and tell you what is realistic before you commit to it.

What happens if I’m not satisfied with a spot after you leave?

Tell us right away and we come back and look at it. If something inside the agreed scope was missed or came out uneven, we return and address it. If the marking is something cleaning was never going to remove — a deeply absorbed stain, etching, or damage that was hidden under the dirt — we explain what it actually is instead of washing the same area harder and risking the surface. We try to flag those areas during the estimate so expectations are set before the first pass.

How long will the work take?

Most single-family house washes, driveways, and patios are finished in a few hours on a single visit. Roof soft washing, larger homes, several surfaces at once, or heavy staining that needs pre-treatment and dwell time take longer, and commercial sites are worked in sections around operating hours. You get a realistic time window with the estimate so you can plan access, parking, and vehicles.

My Alliance home is older, with painted wood trim and porch columns. Can it still be washed?

Yes — older homes with painted wood, porch columns, and mixed materials are exactly why soft washing exists, since high pressure damages aging paint and wood. We inspect paint condition, trim, glazing, and any loose or failing material first, and we tell you where washing would lift paint that is already letting go rather than doing it and handing you the result. Porches, steps, and entry concrete are commonly cleaned in the same visit as the house.
