Driveways and concrete
Driveways, patios, walkways and steps. This is the surface where pressure belongs, and the results are hard to argue with.
Same slab, one pass apart. That line is not a shadow. It is how much of what you have been looking at is growth rather than the actual color of your concrete.
Everywhere else on your property, I keep the pressure down. Concrete is the exception. It can take it, and it needs it. A surface cleaner and real pressure is what pulls years of embedded grime out of the pores instead of just darkening it with water.
It's also the most satisfying thing I do, and the reason half the photos on this site are driveways.
Not new concrete. Not sealed, not coated, not resurfaced. That is the actual color of the slab you already own.
No two driveways price the same. A newer slab with good drainage and a little green on it is a completely different job from an old one that holds water and has twenty years of organic staining in it. That's why I like to see a photo before I quote.
Driveway and apron. Drainage and age decide how long a slab takes, which is why no two price the same.
Side drive by the garage. North facing and shaded, so it goes green long before the front does.
Back patio. Organic staining, years of it. Nothing was resurfaced.
Concrete steps. Moss on a shaded stair is a fall risk, not just an appearance problem.
Brick patio. The color change is the whole job. Nothing was sealed or painted.
Pressure washing takes out organic staining, which is most of what makes concrete look bad in Atlanta: algae, mildew, mold, dirt, pollen residue, the general green film that grows on anything shaded and damp.
Rust and oil usually lighten a lot, and how far depends on how long they have soaked in. Send me a photo and I'll tell you honestly what to expect before I start.
Most of it usually does, and sometimes all of it. Oil that has soaked into a slab for years goes deep, and old rust can stain for good. Send a photo and I'll tell you what I honestly expect.
Drainage and age, mostly. A newer slab that sheds water is quick. An older one that holds water, sits in shade and has decades of organic staining takes considerably longer. I price by how long it will actually take.
Yes, and you should. Setup is most of the overhead on a small job, so anything done on the same visit costs less than bringing me back out.
Cleaning first is what lets a sealer bond properly, so yes, and the order matters. Ask me about sealing when you send photos.
Send a photo of the driveway or patio. That's usually all I need to price it.
Most quotes come back the same day. You don't need to be home.
