They cleaned the gas station canopy and the drive-thru lane at our Mitchell location. The concrete looks much better. A few stubborn stains remain.

Mixed results on our office building entrance in Mitchell. Water pooled in the loading area and nobody squeegeed it.

We use them quarterly for the brewery patio at our Mitchell storefront. Happy with the clean. Scheduling took a couple of follow-ups.

Booked commercial pressure washing for our self-storage driveway in Mitchell. They were fully insured and provided a COI without us asking.

The cleaning was acceptable but the scheduling was a headache. The crew left before we could do a walkthrough.

The fast-casual patio was slick with grease and now it is safe to walk on. Good service. They had to come back for the dumpster pad.

Our dumpster pad in Mitchell had a layer of grime that nothing else touched. Our inspection passed with zero cleaning-related notes.

Our school walkway had years of gum, oil, and grime built up. Very good work overall, though the noise during business hours was a factor.

They cleaned the medical plaza sidewalk but left the surrounding area messy. The gum on the sidewalk was only partly removed.

Our warehouse apron in Mitchell is now part of our monthly maintenance. The gum removal alone was worth the price.
