Booked commercial pressure washing for our medical plaza sidewalk in Walnut Creek. The gum removal alone was worth the price.

Our parking lot in Walnut Creek had a layer of grime that nothing else touched. Happy with the clean. Scheduling took a couple of follow-ups.

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