We Fix Foundations. We Stop Leaks. Now We're Sealing the Deal on Insulation Too.

Quality Waterproofing has built its reputation on a simple foundation, showing up on time, doing the job right, and making sure your home is protected from water damage and foundation problems for the long haul. That hasn't changed. But starting June 1, we have something more to offer.

We're excited to announce that Quality Waterproofing and Foam Engineers are officially coming together as one company: Quality Waterproofing + Insulation.

Why this matters for your home

Water and insulation problems are more connected than most homeowners realize. A damp basement and a drafty, inefficient home often share the same root causes, gaps in your home's envelope that let moisture in and conditioned air out. For years, solving both problems meant calling two different companies. Starting today, you only need one.

Water intrusion and poor insulation lead to costly structural damage and unhealthy living conditions. We repair foundations, stop leaks, and insulate homes so you can feel confident your home is healthy, protected, and built to last.

That's not just a tagline, it's the full picture of what our expanded team can now deliver for you under one roof.

What's staying the same

The faces you know, the craftsmanship you trust, and the commitment to getting it right. The Foam Engineers team brings decades of insulation expertise to a company that already has deep roots in waterproofing and foundation repair. Together we're stronger, and your home is better protected for it.

What this means for you

If you've ever wondered whether your home's water issues and energy inefficiency might be connected, they probably are. Now one team can inspect, diagnose, and solve both sides of the equation in a single relationship.

We're proud of what this company is becoming, and we're grateful to serve the St. Louis community.
