Pressure Washing and Soft Washing in Kennesaw, GA

Driveways, walkways, patios, decks, fences and siding. Georgia humidity and shade grow algae and mildew on everything that holds moisture, and a wash is the cheapest thing that makes a property look cared for again.

Straight about how we do it: the washing itself is done by a specialist rather than by our own crew — the same person on every job, someone we know personally and work with regularly. We quote it, schedule it and stand behind it. He does this work every day, which on soft-washed siding is exactly what you want.

What it costs around Atlanta

2026 market rates, so you can judge any quote you are handed:

• Whole house — averages about $257, with most between $181 and $366

• Driveway — $83 to $207

• Patio — $83 to $166

• Fence — $124 to $249

• Siding — $124 to $1,161, depending entirely on size and material

By house size: 1,500 sq ft runs $124 to $622, 2,000 sq ft runs $166 to $829, and 2,500 sq ft runs $207 to $1,036. Per square foot it lands between $0.08 and $0.41, and the material is what moves it — brick $0.08 to $0.33, vinyl $0.17 to $0.41, stucco $0.25 to $0.41, wood $0.25 to $0.46.

Wood and stucco cost more because they cannot take pressure. That is not an upsell; it is a different technique, and it is the thing worth understanding before you hire anyone.

Pressure washing and soft washing are not the same thing

This is the distinction that decides whether your house looks better or worse afterward, and plenty of cheap quotes ignore it.

Pressure washing uses force. It belongs on hard, non-porous surfaces that can take it — concrete driveways, walkways, block and brick patios.

Soft washing uses low pressure and a cleaning solution that kills the algae and mildew rather than blasting it off. It belongs on everything else: vinyl and painted siding, stucco, wood, and roofs.

Put a pressure washer on vinyl siding and you drive water up behind the panels, where it sits in the wall. On wood you raise the grain and leave permanent lap marks. On stucco you take the finish off. On asphalt shingles you strip the granules and take years off the roof.

There is also a difference in how long it lasts. Blasting algae off leaves the spores; a soft wash solution kills them, so the surface stays clean months longer. A cheaper wash that comes back green by spring was not cheaper.

Power washing and pressure washing — what people mean by each

Most people asking for power washing in Kennesaw and most people asking for pressure washing are describing the same job, and we take both words as the same request. If you call and ask for power washing, nobody here is going to correct you.

There is a real distinction in the trade and it is a narrow one: a power washer heats the water, a pressure washer does not. Heat earns its keep on grease, salt and heavy mildew on concrete, which is why the word shows up more often around commercial pads and equipment yards than around houses. On a Cobb County driveway or a stretch of siding it seldom changes the result.

The choice that does change the result is the one above — whether a surface gets pressure or a soft wash. Get that wrong on vinyl, wood, stucco or a roof and no amount of hot water undoes it. So that is the call we make for you when we come out, surface by surface, and we will tell you where a wash is not worth doing at all.

What Georgia does to a house

The north side goes green first. It gets the least sun and stays damp longest, which is why one wall looks years older than the rest.

Under pine and oak canopy, everything grows faster. Shade plus humidity plus organic debris off the trees is ideal for algae, and it is why shaded Cobb County lots need washing more often than open ones.

Black streaks on the roof are not dirt. They are gleocapsa magma, an algae that feeds on the limestone filler in asphalt shingles. Scrubbing or pressure washing a roof damages it. A proper soft wash is the only sensible treatment.

Concrete near beds and downspouts stains worst, because that is where the water and the organic matter sit. Fixing a downspout that dumps onto the driveway is often worth more than washing it again next year. Gutter cleaning and downspout flushing →

How often it needs doing here

Driveways and walkways: every one to two years on an open lot, annually under heavy shade.

House siding: every two to three years, sooner on the shaded side.

Decks and fences: annually, and always before you stain or seal — sealing over algae just seals it in.

Roof: only when there are visible black streaks, and only soft washed.

Questions we get asked

Will it damage my plants?

Soft wash solution can burn foliage if beds are not wet down first and rinsed after. That is standard practice and it is one of the reasons to use someone who does this daily rather than a rented machine.

Can I just rent a pressure washer?

For a concrete driveway, honestly, yes — it is a reasonable weekend job and we will tell you so. For siding, stucco, wood or a roof, the damage a rented machine does costs far more than the wash.

Do you do it while you are here for other work?

Usually the most efficient way to handle it. If we are already doing a cleanup, gutters or beds, we schedule the wash into the same window so you are not booking two visits.

Does it need to be done before painting?

Yes, and it is not optional. Paint does not bond to algae or chalked siding.
