I met with three others besides Felipe, and he stood out by far. He's a great guy--honest and…read moretransparent--never trying to sell me more than I needed. In fact, he even recommended cost-effective options. I ended up waterproofing the entire perimeter of the basement, with Alex managing the project. The team was friendly, hardworking, and respectful of the property. They not only cleaned up after themselves but actually left the basement cleaner than they found it, going above and beyond. Throughout the process, they were communicative and easy to work with. As I told Felipe before he left today, "I hope I never need to see you again, but if I ever have a basement issue, you'll be the only one I call or recommend."

Trust me don't deal with the water and leaks and mold just get it done. The price was reasonable for the amount of work that was performed. So glad I put that system in.

Last October or so, we had a huge rain (not this much), and our basement got soaked. we lost a lot of memories that we foolishly stored in the basement. Anyway, we reached out to a couple of well-known basement guys to permanently fix it. We stumbled upon United Waterproofing.. Matt, Jason, and their team came over within a day, impressively quick, and offered us multiple options. Within a few weeks, we got the French drain installed, and since then, we have had no issues with the basement. I thought of sharing this shout-out with a local small business. If anyone needs help with the basement, you can rely on these guys.

The crew of 3 worked aprox 5 hours each day and took 2 days to complete. It is hard dirty work and the guys were great. Respectful and pretty quiet. The system has been in for a week and the basement is dry...and getting better daily. A few downsides...the 70 feet of pipe in the ground has a giant mound over it the whole length which I now have to fix. We didn't have basement access from outside so the crew had to pass 1 bucket at a time out a window that unfortunately is right at our main entry. They did the best they could, but the decking and the shingle siding at the window area was trashed. Covered in mud/cement splatters and pretty scraped up despite the cardboard and plastic they laid out. I have some clean up work to do there as well. There is no "kim" copyright special cement...its quick crete... just add water home depot anyone can purchase. I figured about 1200 in labor and 2400 max in materials ( gravel,hoses,pitboss,matting and cement) I paid 9100.00 pretty big profit somewhere. All in all though....it was a flooding situation and the guys worked really hard and the system designed is definitely doing the job.

In…read morethe recent round of rain storms, my sump pump stopped working as it is supposed to, and I ended up with about 5 inches of groundwater in the basement. I was able to get the sump pump working again, but 3 days after it stopped raining, I was still getting a lot of water in the pit. I found a sticker for Contractors Waterfproofing, and figured they might of installed the system for the old owners, so I gave them a call. From the moment he picked up Greg was service oriented and responsive. He asked for my address to look up the job, and when he couldn't find it, he called back within 5 minutes to ask what was going on. I explained the problem, and he immediately told me that was normal for my part of town, and told me I just needed to replace the pump and I would be fine. He offered me a price that was half what his competitors charge, but I told him I would do the work myself since I am capable. He then answered a ton of questions about the install, and we had a great conversation about life and how my son could maximize his potential long-term, as he is currently a plumbers apprentice. The bottom line is that the system Greg installed 20 years ago is still working perfectly, and when the pump failed, he not only gave me a fair price, but then walked me through how to do the job myself. This is unheard of in 2025. Greg will get all my business going forward. Thank you.
