Our medical plaza sidewalk in Durham had a layer of grime that nothing else touched. They worked overnight so we did not lose a single hour of business.

Our warehouse apron had years of gum, oil, and grime built up. Pleased with the result. Communication could be more proactive.

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