I wanted to wait to write a review to allow for a really good test of the new system Giovanni and team installed in my home. After these many weeks of on and off heavy rains, I can say that I can rest easier during storms like the ones we've had. The french drain has more that handled the load thrown at it. Thank you United for keeping my basement dry!!!

United Waterproofing installed french drains around the perimeter of my finished basement eight years ago, after repeated incidents of minor flooding and displaced tile flooring. Since then, there have been no problems. Earlier today, I noticed that the pipe leading from the basement outside the house had cracked, likely due to an encounter with a lawnmower. With heavy rain expected tonight, I reached out to United. My call was returned within minutes. By early afternoon, Giovanni came (and I live about 45 minutes away from United's office) and handled the repair. It's raining steadily now, and I don't have to be concerned with water cycling back into the basement, which likely would have happened if the pipe hadn't been repaired. It's rare to find this level of customer service today.

You can't beat the service you get with United Waterproofing! My husband called Giovanni today due to our pump constantly running but it didn't appear to be expelling water. Giovanni worked with my husband over the phone and then came in person in very quickly to check out the issue! They were able to get it resolved in a matter of minutes as well as were able to come up with a plan of action in the case this issue happens again. You truly can't beat the service!
