Concrete cleaning prices per square foot
Flatwork is priced by the square foot, measured on site, so the number is the same whether it is a patio or a loading dock. Most residential concrete runs 15 to 30 cents a square foot. Recurring commercial work runs lower, because a surface that is cleaned on a schedule never gets the chance to build up again.
| Surface | Typical size | Typical range |
|---|---|---|
| Driveway, two-car | About 600 sq ft | $120–$200 |
| Patio | 200–400 sq ft | $60–$120 |
| Front walk and steps | Usually priced with the drive or patio | $0.15–$0.30 / sq ft |
| Pool deck | 400–800 sq ft | $120–$240 |
| Commercial flatwork, recurring | Quoted per visit | $0.08–$0.20 / sq ft |
Driveway cleaning
A Triangle driveway collects three things: oil where the cars park, tire marks at the turn-in, and a gray-green film of mildew wherever the slab sits in shade. Pollen and red clay settle on top of all of it every spring. We pre-treat the oil with a degreaser, run a flat surface cleaner across the whole slab with hot water for an even, stripe-free finish, then wand the edges, the expansion joints and the apron by hand. Stamped, sealed and exposed-aggregate drives get lower pressure and a wider fan so the finish stays where it is.
Patio cleaning
The patio sits in the shadiest, wettest corner of the lot, so it is usually the greenest surface on the property and the slipperiest. We treat the growth first so it dies rather than rinsing off and returning, then surface-clean the slab. Pavers get a lower-pressure pass that leaves the joint sand in place. Furniture, the grill and the planters are moved and put back.
Sidewalk and walkway cleaning
The entry walk and the public sidewalk out front are the first concrete a visitor steps on, and they are where gum, bird droppings and the dark drip line under the eave collect. Hot water lifts gum and grease that cold water only spreads. Steps and stoops are included, brick or concrete. For HOAs, apartment communities and storefronts we put the common-area walks on a schedule, so the path to the door never gets the chance to go green.
