Mining-era concrete and masonry in Georgetown has had over a century to weather, more than the newer construction on the surrounding forested lots, which also shed more pine debris onto driveways and walkways.
Driveways, patios, decks, fences, walkways, siding — if it is outside and it is dirty, it is on the list. We bring our own high-pressure equipment; all we need from you is a water tap, and it does not need to be hot. What a job costs comes down to two things: how much surface there is, and how badly it has weathered. A patio that gets swept every week and a driveway that has not been touched in five years are not the same job even at identical square footage, which is why the quote follows a look at the actual surface rather than a table of rates. There is one surface we will not put a pressure washer on, and that is your roof. Pressure strips the protective granules off asphalt shingles, and on soft roofing it does real damage — so roofs get a different method entirely, mechanical removal of heavy moss followed by a treatment that kills lichen at the root. If someone quoted you a pressure wash for your roof, that is the part worth asking about. Siding gets the same care as a roof, just a different fix: some people call washing the outside of a house a house wash, or a soft wash when it runs at lower pressure, and that is closer to what siding actually needs. Stucco, wood siding and painted surfaces do not take a driveway-strength blast the way concrete does, so on those we back the pressure down and change the tip, the same adjustment we make for a wood deck. Small jobs meet a $220 floor. The washer has to be trailered out, hooked to your tap and primed whether it then runs for one hour or five, and that setup is the part of the day a single walkway cannot carry on its own.
