Foundation Repair & Waterproofing in St. Louis
## Protecting St. Louis Homes From the Ground Up
Your foundation is the most important part of your home — and in the St. Louis area, expansive clay soil, heavy rains, and freeze-thaw cycles put it under constant stress. Over time that leads to foundation cracks, settling, bowing basement walls, and water seeping into your basement or crawl space. Left alone, small problems turn into expensive structural damage.
Fred's Foundation Repair & Waterproofing helps homeowners across Oakville, Mehlville, Affton, Arnold, Fenton and the rest of South County keep their homes dry, level, and structurally sound. From helical and push pier installation to full basement waterproofing systems, we diagnose the real cause and fix it for good — not just patch the symptom.
Whether you're dealing with an emergency flooded basement after a storm or planning routine maintenance to protect your investment, we're ready to help with a free, no-obligation inspection.

FAQ
## Foundation Repair & Waterproofing FAQs
Answers to the questions St. Louis homeowners ask us most.
How much does foundation repair cost in St. Louis? +
Foundation repair costs in the St. Louis area vary widely depending on the cause and severity — a simple crack repair may run a few hundred dollars, while pier installation for a settling foundation can run into the thousands. The only way to know for sure is an on-site evaluation, which is why we offer a free, no-obligation inspection and a written estimate before any work begins.
What are the signs I need foundation repair? +
Common warning signs include stair-step cracks in brick or block, bowing or leaning basement walls, doors and windows that stick, uneven or sloping floors, gaps around trim, and water seeping into your basement. If you notice any of these, it's worth getting an inspection before the problem grows.
Do you offer emergency or flooded basement service? +
Yes. If you have water actively coming into your basement after a storm, call us at [(314) 350-6678](tel:3143506678). We provide emergency basement waterproofing and water-removal solutions to protect your home and get things dry as quickly as possible.
How do I know if my basement needs waterproofing? +
If you see water after rain, damp or musty smells, white chalky residue (efflorescence) on walls, mold, or a sump pump that runs constantly, your basement likely needs waterproofing. We'll identify whether you need interior drainage, exterior waterproofing, a sump pump, or a combination — and recommend only what your home actually needs.
What areas of South County St. Louis do you serve? +
We serve Oakville, Mehlville, Affton, Arnold, Fenton, Imperial, Barnhart, Concord, Lemay, Crestwood, Sunset Hills, Kirkwood, Webster Groves, and the greater St. Louis City and County area. Not sure if we cover your town? Just give us a call.
