"We had water problems in our basement. Andrew was willing to not only answer our call, but offered to walk us through it via video call. He then went above and beyond and offered solutions as well as a written report that explained everything."

Customer Testimonials
We think we're good at waterproofing, but don't take our word for it. Listen to what our customers have to say!
Greg Dunn and Quality Waterproofing were very responsive when we had a sump pump problem. They were able to get a tech here even with the high workload after a storm, spotted the problem, and got it fixed quickly.

I have trusted Quality Waterproofing with many home projects and they have never failed me! Andrew Timp and the service team are amazing! Will continue referring them as well as using them for my own projects!

Quality Waterproofing is a company of integrity. They focus on “going the extra mile” to see that their customers receive exactly what’s needed at reasonable cost. They don’t oversell. In fact they will counsel you to follow the most prudent approach.

They were amazing! They found a plumbing problem that could be the water issue. Rather than recommending expensive work off the bat like another company I contacted, they recommended I fix the plumbing issue first and see if I still had the problem. Fantastic.

We had four leaking cracks in our basement repaired and we’re very happy with the service received. All of the employees were very kind and professional. The repairs were done quickly and no messes were left! Highly recommend!

They didn’t try to sell on anything unreasonable and even recommended alternative solutions as to not run my bank dry. Will be calling for any and all related issues in the future.
