About Us

Jay Waterproof has been repairing water problems in basements since 1965.

This is an industry that sometimes looks for ways to cut corners- but we get it done right, using the best in waterproof systems and foundation crack repair methods.

We are known for our structural foundation expertise and stand behind the basements we waterproof with an A + rating from the BBB and an uncommonly strong guarantee.

The only difficulty you could have would be finding another company to do the level of results we provide at price-points that typically saves money, and the savings can often be quite substantial.

We can create a dry basement in any home or business, and would like to thank you in advance for considering us.

Our location is 3950 Old State Route 21, St Louis, MO 63052. See map below. 

Jay Waterproof serves the St Louis area anywhere help is needed with basement water problems.  Once we are on the job, you'll be very glad you found this website.
