What pressure washing actually does
It uses 2,500–4,000 PSI of water (often with detergent) to lift oil, moss, salt stains, and embedded dirt out of porous concrete, pavers, or brick. Done right: driveway looks new. Done wrong: surface etching, cracked joints, landscaping damage.
The 4 things DIYers get wrong
- Too much PSI. Box-store rentals are often 3,500+. On older concrete, that etches the surface permanently.
- Wrong nozzle. A 0° (red) nozzle leaves visible lines. Use 25° (green) or 40° (white).
- No pre-treatment. Oil and organic stains need a degreaser or sodium hypochlorite soak first — not just high-pressure water.
- No containment. Runoff with detergent kills grass and is technically illegal in Cook County if it reaches storm drains.
When DIY makes sense
Small concrete patio, newer surface, no oil stains, no landscaping to protect. Budget a full afternoon.
When a pro is the move
- Driveway larger than 400 sqft.
- Pavers or stamped concrete (needs re-sanding/sealing after).
- Oil stains older than a year.
- Siding, decks, or brick facades (one wrong angle = water intrusion behind the siding).
What we charge
