Power Washing in Potomac, MD

Force versus chemistry, essentially. Soft washing applies a solution, lets it work, and rinses gently, so what is growing is killed off rather than ground away.

For masonry, coated trim and cedar, soft washing is the correct method. Easier on the material, and longer lasting, because the growth was killed. Concrete is the exception: driveways get pre-treated and then washed at genuine pressure. There is a good general overview of pressure washing, and this power washer vs pressure washer comparison covers the terminology.

Which is why every surface sets its own limit here. Masonry and cladding are soft washed. Cedar and decking take dedicated wood products at low pressure. Only concrete gets a stronger wash, and only after pre-treatment.

Anything already weak outside, open joints, lifting coatings, a soft sill, mention it on the walkthrough. Changing the approach is free. Hand you a repair.

Two to four hours on a mid-sized job. Potomac properties frequently exceed that simply on square footage, and a full exterior can run most of a day. A realistic number comes at the walkthrough, not after we have started.

Surfaces, footprint and access all move the number, and on acreage the footprint moves it most. So we measure in person, at no charge, and quote your property rather than a number over the phone.

No charge for the visit, and no commitment attached to it.

Licensed, registered and bonded, and happy to show the certificate on site. Worth asking of anyone who brings equipment onto your property.

Yes, and it is worth raising when you book, because a good part of Potomac is not on public water and sewer. Montgomery County’s own Glen Hills Area Sanitary Study, carried out under the Potomac Subregion Master Plan, records that the majority of homes in that area depend on private wells and septic systems, most of them built between the 1950s and 1970s, before current well and septic testing and permitting rules existed.

Two things follow from that. Your water is coming out of your own well rather than a municipal main, so recovery rate matters on a long job and we plan the sequence around it instead of running a well hard for hours. And rinse water landing over a drainfield is worth avoiding, so we position and direct runoff away from it.

The county facts above are accurate and cited. What is not stated here is whether the crew carries its own water tank for well-served properties, which would be a genuine selling point in 20854. Confirm it and we will add one line.

Standard answers are “no, you don’t need to be home once the walkthrough is done” and “yes, we use an outdoor spigot”, but both are operational facts we shouldn’t guess at. This question stays in: it’s one of the most common objections and answering it lifts form fills.

Spring fills up first, once the pollen drops and the winter growth shows. Given how long these properties stay damp under tree cover, autumn works just as well and the calendar is far easier.
