The last waterproofing call you'll have to make

Some contractors offer a quick fix knowing you'll have to call them back for more business later. Our goal is to be the last call you make so that you never need to worry about basement fixes again.

Our History

Serving St. Louis since 1955

Quality Waterproofing was started in The Grove district in 1955 to meet the needs of the St. Louis housing boom after World War II.


By the 1980's Quality Waterproofing was leading innovation by becoming one of the first waterproofing applicators in America to embrace the new technology of spray-applied waterproofing.


For over 40 years, Quality Waterproofing has called Valley Park home as it continues to serve the St. Louis metro area with industry-leading waterproofing, foundation repair, concrete raising, and garage floor coating.

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 had an excellent experience with Quality Waterproofing! Eric came to bid the work, and he was fun to interact with. Also gave me an honest and fair assessment/bid, thoroughly explaining the process. Great attitude and enthusiasm! Greg performed the work, and he also had a positive attitude and energy! Very polite and professional, easy to engage with. The end result was better than I expected, and from the first call to the end was around two weeks.

I recently purchased a home in St. Peters and had some concerns about water damage in an air duct running through a slab, as well as the grade on one side of the home. Eric came to inspect and was highly knowledgeable and professional, taking time to answer questions and explain his findings without coming across like a salesman with a pitch. I would absolutely recommend Quality Waterproofing.

They were amazing! They found a plumbing problem that could possibly be the source of our 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.

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.

FAQ

Frequently Asked Questions

We know that fixing the structure of your property can bring a lot of questions. We hope this helps. Please contact us if you need further clarification!

How long have you been in business?

Many companies will state that they have a certain number of years of combined industry experience, but they do not tell you how many years they have been in business as a company. Since most services are accompanied by a warranty that extends beyond the date of work completion, it is important to know you have a company that lasts. Quality Waterproofing has been in business since 1955. We belong to both the Basement Health Association and the Home Builders Association of St. Louis.

Is your warranty verbal or in writing?

Are you accredited with the BBB?

Are you fully licensed and insured?

Do you perform a drug and background check on your employees?

Are you a franchise?
