Our grocery store sidewalk in Walnut Creek is now part of our monthly maintenance. They cleaned the dumpster pad and the smell is gone.

The school walkway at our Walnut Creek site had a black film of grime on it. Very good work overall, though the noise during business hours was a factor.

Our office building entrance in Walnut Creek had not been cleaned in years. They were fully insured and provided a COI without us asking.

They cleaned our gas station canopy and the concrete looks new. Great outcome. I would have liked more notice before they arrived.

We hired them for the parking garage and ended up adding a recurring contract. Our inspection passed with zero cleaning-related notes.

Work was fine. Communication was poor throughout. The crew left before we could do a walkthrough.

The result did not match what was quoted. We were billed for work that was not performed.

Average service. The invoice did not match the original quote. The final invoice was higher than the quote.

We needed the fast-casual patio cleaned before a corporate walkthrough in Walnut Creek. Good service. They had to come back for the dumpster pad.

They handled the restaurant patio at our Walnut Creek location overnight so we never closed. They came back to touch up an area at no charge.

They removed oil stains from our convenience store forecourt that I thought were permanent. They used hot water and a degreaser that actually worked.
