Clean Crawlspace did a great job from start to finish including the initial free quote. I had them install a sump pump and french drains in my crawlspace and they completed the job in 3-4 days. They were booked up for a month but the wait was definitely worth it and I’m happy with the results. Only thing that I wasn’t sure about was the zoeller sump pump they installed, it didn’t really look like a brand new pump from what I could tell, but I forgot to ask.

Excellent workers, excellent front man. They did a great job. The only negative was that it was a bit pricey for what they did.

Excellent experience from the initial site survey through work completion. The provided information packet was very informative. Crawl space is now neat, pest free and no longer has a damp/musty odor.

My crawlspace had standing water show up during heavy rains. I had called clean crawlspace to send someone to take a look and suggest a fix. The crew was very patient and efficient, all the way from scheduling the appointments, communicating the issue, options for fix and pros and cons. They gave me a working solution to install a sump pump at a good rate compared to some other companies that suggested much more extensive and expensive fixes like French drains around the whole house. The installation crew finished their work in about 4 hours and were on their way with minimal disruption to my work day. I only had a minor and purely aesthetic issue is with the way the drain left the house through the front yard to the side of the street. There was a decent strip of the lawn that was dug up and backfilled, and more care could have been taken to preserve the sod on top. Now I have a feet width gap from my house to the street with no grass and with lots of ups and downs in it. While this part wasn't explicitly discussed with the crew, I feel it still could have been better.

Good service. Know what they’re doing. Not the cheapest. Some issues around communication. But overall satisfied.
