Average service. The invoice did not match the original quote. The final invoice was higher than the quote.

They pressure washed our church parking lot and the difference is night and day. They finished ahead of schedule and under the quote.

Our convenience store forecourt had rust stains and graffiti — both gone. They were fully insured and provided a COI without us asking.

I manage the property and hired them for the apartment breezeway in Peninsula. The grease trap area finally does not smell.

Our retail center had years of gum, oil, and grime built up. Great outcome. I would have liked more notice before they arrived.

They handled the church parking lot at our Peninsula location overnight so we never closed. Happy with the clean. Scheduling took a couple of follow-ups.

The storefront at our facility was embarrassing before they came out. Pleased with the result. Communication could be more proactive.

They did the work, but the crew arrived well outside the window. Water pooled in the loading area and nobody squeegeed it.

We hired them for the brewery patio and ended up adding a recurring contract. Good result overall. One section of the lot needed a second pass.
