Pressure Washing
Clean surface. Better results. Longer-lasting work.
A clean surface is the foundation of every maintenance service we provide. Sealcoat applied over oil stains, moss, and road debris won't bond properly — it peels within a season. Striping over a contaminated surface fades fast and lifts at the edges. Crack filler applied to debris-packed cracks doesn't seal the crack; it just sits on top of it.
Pressure washing is how we prepare surfaces for the work that follows. It's also a standalone service for commercial property managers who want their lots, drives, and concrete surfaces looking professional — or who are dealing with moss, algae, or oil contamination that's affecting surface condition.
What our Pressure Washing service covers.
- Parking lot surface cleaning (asphalt and concrete)
- Driveway and access drive cleaning
- Concrete sidewalk and flatwork cleaning
- Oil and fuel spot treatment and washing
- Moss and algae removal from asphalt surfaces
- Pre-sealcoating surface prep washing
- Pre-striping surface prep
- Loading dock and industrial surface washing
How Pressure Washing works.
Surface assessment
We identify areas of heavy contamination — oil spots, moss, standing stain patterns — before washing begins. Oil spots require a degreaser treatment prior to pressure washing; otherwise the oil gets spread rather than lifted.
Degreaser treatment (where needed)
Commercial degreaser is applied to oil and fuel contamination and allowed to dwell before washing. This breaks down the petroleum residue so it lifts cleanly rather than getting pushed around the surface.
Pressure washing
Hot water pressure washing is more effective than cold water for petroleum contamination and moss removal. We use equipment appropriate to the surface — high pressure on concrete, lower pressure on older or weathered asphalt where surface aggregate is exposed.
Rinse and inspection
The surface is rinsed clean and inspected for residual contamination. Oil-saturated areas may require a second treatment. We confirm the surface is ready for whatever comes next — sealcoating, striping, or just a clean finished appearance.
Why choose A-Team for Pressure Washing.
Prep that matters
We pressure wash before sealcoating because it makes the sealcoat last longer. Not everyone does.
Commercial equipment
Truck-mounted pressure washers, not consumer units. The difference in cleaning power is significant.
Oil contamination in asphalt doesn't just look bad — it breaks down the binder. Petroleum from vehicle leaks softens the asphalt surface and accelerates raveling. Heavy oil saturation may require that section to be removed and patched rather than just cleaned.
The Puget Sound's mild, wet climate is ideal for moss and algae growth on asphalt and concrete. Moss holds moisture against the surface, accelerating deterioration. Regular pressure washing — typically annually — prevents accumulation from becoming a structural issue.
Pressure washing alone doesn't seal, waterproof, or protect your asphalt. It prepares the surface for the work that does. If you're washing to prep for sealcoating, plan to seal within a few days after washing.
We provide pressure washing for asphalt and concrete surfaces throughout the Puget Sound — Puyallup, Sumner, Tacoma, Auburn, Federal Way, SeaTac, Covington, Maple Valley, Bellevue, and the greater Seattle area.
