Driveway Pressure Washing in Boston MA

Concrete driveways and walkways in Greater Boston accumulate years of dirt, oil stains, algae, and winter salt damage. Pressure washing concrete properly is different from washing wood or siding — here's how we approach it.

Concrete Handles Higher Pressure

Concrete can handle 2,500-3,500 PSI without damage, allowing more aggressive cleaning than softer surfaces. This is important for removing embedded oil stains, tire marks, and algae that have penetrated the surface. We use surface cleaners (rotating nozzle attachments) for flat concrete work — they clean evenly without the streaking that a wand can leave.

Oil and Stain Treatment

Road oil and automotive oil stains require pre-treatment with degreaser before pressure washing. We apply, let it dwell, then wash. Severe stains may not come out completely even with treatment — we're honest about what's achievable before starting.

Winter Salt Damage

Boston winters and aggressive road salting leave salt and calcium chloride on driveways and walkways. Annual pressure washing removes this buildup and helps prevent the surface deterioration that salt causes over time. This is one of the reasons spring driveway washing is popular in Newton, Needham, and Dedham neighborhoods where properties have significant concrete areas.
