Basement waterproofing and foundation repair company. Family owned since 1957 with over 300,000 dry basements. Free consultations. Lifetime warranties available. Award winning company.

"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

"Would HIGHLY NOT RECOMMEND. Requests to discuss significant concerns regarding our project went ignored and were only acknowledged after we filed a complaint with the Better Business Bureau & IL Atty General due to some of their practices. Be aware of your rights and would strongly advise you to document all encounters and request all details be finalized in written documentation no matter how small it may seem at the time. Lastly, know your rights to request a Sworn Statement (A document that lists the contractors and suppliers that provide material or labor to a construction project.

For 18 years I was an Outside Sales Representative for nearly all aspects for the building industry. Part of my success was the understanding of how these products worked, were installed and repaired. I have been servicing, repairing and installing every aspect of a home and yard for as long as I can remember. I will work with every customer to meet their needs for their project. Pricing is always fair and negotiable. Since I have sold most everything we would need for your project, I can also help you get the materials at a great price.

Foundation Repair questions, answered by experts

Trenchless sewer replacements are actually a great solution for sewer lines located under concrete. A professional can still sleeve and burst old piping to make room for a new one without having to dig up your slab.

Yes, thicker concrete is less likely to crack. The thicker the concrete is, the less susceptible it is to extreme changes in weather conditions that often cause concrete to crack or chip. If you’re unable to install a thicker concrete driveway for any reason, you can also ask your professional to install more rebar or wire mesh to provide greater strength and better resilience to damage.

Foundation repair can affect home value positively or negatively. If you address the underlying issue and hire a foundation repair contractor to complete the work—especially one that includes a warranty for the work—then your repair will likely increase your home’s value. If you fail to pull proper permits and cannot prove that a licensed expert completed the work, there’s a chance buyers will view your home in a negative light and end up offering less for your property.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.
