What we started with
The concrete was covered in a gray film, with darker staining along the edges and around the walls where water and debris collect. On light-colored concrete, that buildup makes the whole space look older than it is.
Before
AfterHow a patio like this is cleaned
Stained areas are pre-treated first. The open concrete is then cleaned with a rotary surface cleaner for an even finish, and the edges and corners are detailed by hand. Walls and wall caps around the patio can be cleaned in the same visit.
Why the result looks even
The open area was cleaned with consistent distance and overlap, so there are no light and dark stripes. The edges were matched to the middle, which is where many DIY jobs fall short.
Keeping it clean longer
Sweep leaves before they sit and stain, keep sprinklers off the concrete where possible, and wipe up spills quickly. Most LA patios look their best with a professional clean once a year, or more often in shaded spots that stay damp.
What a patio clean costs
Our calculator prices patio cleaning at $0.65 per square foot as of October 2026, with a $195 minimum per visit. Adding a driveway or walkway in the same visit earns a bundle discount.
