Pressure washing in Philadelphia

Philadelphia's tap water is moderately hard or hard, the Water Department says, and how hard depends on which treatment plant serves your part of the city. Hardness comes from minerals like calcium and magnesium. The department says they react with soap to form insoluble deposits, and that can affect everyday washing. Hose water carries the same minerals as the kitchen tap.

A house on the city's historic register brings in the Historical Commission. Its rules list cleaning masonry as an alteration, alongside reroofing and replacing doors and windows. Its staff also write limits into approvals. Two entries in the June 2024 permit log carry the same condition: power washing not to exceed 500 psi.

Back at the hose, it helps to know which plant fills it. In the department's 2025 report, Baxter, which serves the Northeast, the Far Northeast and much of North Philadelphia, averaged about 6 grains per gallon. Belmont, which serves everything west of the Schuylkill, averaged about 9, though most of that area also gets some water from the other two plants. South Philadelphia and Center City get a mix as well. Queen Lane, which serves the Northwest, came in hardest, at about 10.

Questions homeowners ask

How accurate is a photo estimate?
It’s a ballpark, not a quote. A photo gives us a good read on the surface and how dirty it is, but a pro who sees the whole property will always be more precise. Use our number as the range to expect before you start calling around.
How is pressure washing priced?
Mostly by the square footage and the surface — a concrete driveway is cheaper per foot than siding or a wood deck, which need a gentler soft-wash. Heavy algae, mildew, or oil stains add to it because they take detergent and a second pass.
Will pressure washing damage my siding or deck?
It can if it’s done at full pressure on the wrong surface — that’s why good pros soft-wash siding and wood. Our ballpark factors in the gentler method for delicate surfaces.
Is this really free?
Yes. No signup, no credit card, no spam. We only make money if you choose to connect with a local pro — and that’s up to you.
What photo works best?
One shot showing the full surface you want cleaned — the whole driveway or the side of the house — gives the best read on the size and how dirty it is.
