"I hired Waterproof Solutions in January 2022 to install an interior drain and sump on two walls ($5,000, lifetime warranty on treated walls). In June 2025, after an extremely wet spring in St. Louis, water entered through a wall they treated. The sump pit has been bone dry and the pump has never run since installation. I requested a refund, per the terms of the contract. On June 11, their representative said the company had changed ownership and would not honor the prior warranty. As of today, the issue remains unresolved. I will update this review if the company provides a fair resolution."
