About Sioux Falls Basement Pros
Locally owned. Locally trusted. Built to fix wet basements and unstable foundations the right way the first time.
Why We Started
Sioux Falls Basement Pros was founded by people who grew up in this town and saw too many friends and neighbors get burned by out-of-town contractors who showed up, oversold, underdelivered, and disappeared. We started this company on three principles: be honest, do the work right, and stand behind it forever.
That's why every waterproofing system we install carries a lifetime transferable warranty — and why we still answer the phone when you call about a job we did years ago.
What Makes Us Different
The waterproofing business isn't glamorous. There's no shortage of fly-by-night operators who quote a job high, push a contract on the kitchen table, and either disappear or do shoddy work. We've had to fix more than our share of those installations. Here's how we're structured to be different:
1. We Fix the Cause, Not the Symptom
Most basement leaks have a specific source. A horizontal crack from frost pressure. Hydrostatic seepage at the cove joint. A failing sump pump. Flashing that was never installed correctly above an egress window. Our inspectors are trained to identify the actual root cause, explain it to you in plain English, and recommend a fix that's targeted — not a one-size-fits-all $15,000 system you don't need.
2. We Quote Fixed Prices, Not Pressure
The estimate you receive at the inspection is the final price. No "today only" discounts that disappear if you ask for time to think. No surprise change orders mid-project. If we run into something unforeseen, we stop and discuss it with you before adding a dollar.
3. We Stand Behind Our Work — Forever
Our interior waterproofing systems carry a lifetime transferable warranty. That means the warranty stays with the home if you sell, which is genuinely valuable at closing. Our foundation repairs carry a 25-year structural warranty. We register every warranty against your address, so even if you lose the paperwork, we have you on file.
4. We Hire Locally and Train Heavily
Every technician on our crew is a Sioux Falls-area resident. We don't use traveling subcontractors. Our installers go through a structured training program that covers diagnosis, installation methods, customer interaction, and cleanup standards. The crew that arrives at your home is our crew.
5. We're Fully Licensed and Insured in South Dakota
We carry general liability insurance, workers' compensation insurance, and the specialized environmental insurance required for mold remediation. Documentation is available for any homeowner who asks.
