We needed the apartment breezeway cleaned before a corporate walkthrough in San Francisco. The building looks like it was just built.

Our sidewalk was a grease magnet — not anymore. Our inspection passed with zero cleaning-related notes.

Our retail center in San Francisco was the first thing customers saw — now it is spotless. No damage to the paint, signage, or landscaping.

I manage the property and hired them for the dealership lot in San Francisco. They sealed the concrete after cleaning it.

We had them out to our San Francisco location for the office building entrance and the loading area. Great outcome. I would have liked more notice before they arrived.

They cleaned the apartment breezeway at our San Francisco location before we opened for the day. The grease trap area finally does not smell.

We had them out to our San Francisco location for the apartment breezeway and the loading area. They came back to touch up an area at no charge.

Work was fine. Communication was poor throughout. The gum on the sidewalk was only partly removed.

Our apartment breezeway needed degreasing before the health department visit. Good result overall. One section of the lot needed a second pass.

The result was okay. Getting a quote took three calls. Water pooled in the loading area and nobody squeegeed it.

We had our fast-casual patio pressure washed before a health inspection in San Francisco. Good service. They had to come back for the dumpster pad.

They worked around our business hours in San Francisco without a single complaint. Solid work. The quote came in slightly above what I expected.

Booked commercial pressure washing in San Francisco and they handled the water and permits. The concrete looks much better. A few stubborn stains remain.

The warehouse apron at our San Francisco site had a black film of grime on it. They cleaned the dumpster pad and the smell is gone.

Our parking lot in San Francisco is now part of our monthly maintenance. The gum removal alone was worth the price.

Our convenience store forecourt had years of gum, oil, and grime built up. They worked overnight so we did not lose a single hour of business.
