The Advantage
The CleanSlate Advantage in Pittsburgh
From the slate roofs of Shadyside to the concrete driveways of the South Hills, Pittsburgh homes need more than a generic pressure washing service. We’ve spent years learning what the local climate, local materials, and local architecture actually require, and we bring that knowledge to every job.

Architectural Focus
Techniques matched to Pittsburgh’s traditional materials — brick, slate, concrete block, and older wood siding that demands a soft touch.

Why it matters
Dirt You Can See Is Just the Beginning
Algae, mold, and ground-in grime aren’t just cosmetic problems. Left alone, they eat into paint, accelerate wood rot, and work on your concrete from the inside out. Routine exterior cleaning isn’t a splurge — it’s basic home maintenance that pays for itself in avoided repairs.
what we clean
Every Surface. Done Right.
Algae, mold, and ground-in grime aren’t just cosmetic problems. Left alone, they eat into paint, accelerate wood rot, and work on your concrete from the inside out. Routine exterior cleaning isn’t a splurge — it’s basic home maintenance that pays for itself in avoided repairs.
Full House Wash
We clean your home from the roofline to the foundation — siding, trim, soffits, and everything in between. Biodegradable detergents loosen organic buildup while calibrated pressure removes it without lifting paint or damaging caulk. The whole exterior, not just the street-facing side.
Driveway & Sidewalk Cleaning
Concrete is porous and picks up everything — oil, tire marks, freeze-thaw staining, and years of foot traffic. We apply a specialized surface cleaner and degreaser, rinse thoroughly, then finish with a premium siloxane sealer that locks out moisture and slows down future cracking.

Deck, Patio & Fence Washing
Wood and composite surfaces need a gentler hand than concrete. We use a soft-wash technique that removes mold, mildew, and surface grime without raising the grain or splintering the boards. We move the furniture, do the work, and leave everything barefoot-ready.

Whatever Your Home Is Made Of
Different parts of your home call for different pressures, different temperatures, and different chemistry. We don’t take a one-size-fits-all approach, because your house isn’t one-size-fits-all.
Vinyl Siding
Low pressure, correct detergent, and attention to the seams where mold sets up camp. No streaking.
Brick & Stone
Porous surfaces need patience. We clean deep without driving moisture into the mortar joints.
Slate
A Pittsburgh original. We handle it the way it deserves — with soft-wash and chemistry that preserves the surface.
Composite & Hardie
Tough but not immune to surface staining and algae. We treat it gently and completely.
Concrete
We clean and seal — because sealing is the part most people skip, and it’s the part that actually prevents future damage.
Wood
Soft wash only. Too much pressure raises the grain and can cause splintering. We’ve been doing this long enough to know the difference.

Local Reviews
“I was embarrassed by how dark our roof had gotten. After one visit, it looked like we’d had it replaced. Couldn’t believe the difference.”
Patricia Holloway
Shadyside Resident
“Called on a Tuesday, they were out by Thursday. Fast, professional, and my gutters have never looked this clean. Highly recommend to anyone in the area.”
David Friedman
Squirrel Hill Resident
“The crew was on time, explained exactly what they were doing, and cleaned up afterward. Our 1920s colonial roof looks 20 years younger.”
