They cleaned the hotel entrance at our Portland, ME location before we opened for the day. They used hot water and a degreaser that actually worked.

They removed oil stains from our warehouse apron that I thought were permanent. They were fully insured and provided a COI without us asking.

Average service. The invoice did not match the original quote. They did not cover the landscaping and some plants were flattened.
