They cleaned the bank drive-up and the drive-thru lane at our St. Louis location. They worked overnight so we did not lose a single hour of business.

The apartment breezeway was slick with grease and now it is safe to walk on. They used hot water and a degreaser that actually worked.

They handled the parking lot at our St. Louis location overnight so we never closed. Only knocking a star because the start time slipped by an hour.

They pressure washed our drive-thru lane and the difference is night and day. The grease trap area finally does not smell.

Our brewery patio was a grease magnet — not anymore. They were fully insured and provided a COI without us asking.

They removed oil stains from our drive-thru lane that I thought were permanent. They worked overnight so we did not lose a single hour of business.

Our school walkway had years of gum, oil, and grime built up. The sidewalk is no longer a slip hazard.

Our loading dock needed degreasing before the health department visit. Very good work overall, though the noise during business hours was a factor.

We hired them for the brewery patio and ended up adding a recurring contract. Great outcome. I would have liked more notice before they arrived.

They pressure washed the gas station canopy and the dumpster area in one visit. Our inspection passed with zero cleaning-related notes.

Our warehouse apron in St. Louis had a layer of grime that nothing else touched. Solid work. The quote came in slightly above what I expected.

Our self-storage driveway had rust stains and graffiti — both gone. Happy with the clean. Scheduling took a couple of follow-ups.

They cleaned the retail center but left the surrounding area messy. The dumpster pad still had grease on it.

Acceptable job, but I expected the whole church parking lot to be done. The crew left before we could do a walkthrough.
