"My husband and I had a wonderful experience with The Real Seal in July 2024. They fixed a bowing foundation and waterproofed the basement for future finishing. Their team was prompt, respectful, organized and thoroughly educated us on the drainage tile system, installation process and prevention. Thank you, Real Seal for being the flawless first step to our dream basement/family space!"

"I had been having water leakage problems into my lower level family room for quite some time. Real Seal correctly diagnosed the problem, quoted a reasonable price, showed up to perform the work per agreed upon date and fixed it permanently. Even with the wet spring this year, I have not had any further water leakage problem. I highly recommend this company"

"A previous owner of our home built out the basement but the construction company he used did a poor job of insulating and placing the pipes coming  into the basement bathroom.  In the winter, on the coldest days,  we were forced to let the faucet drip and ran a heater to prevent the pipes from freezing.  Toptec was one of four plumbers I called to explain my situation.  All on Angies List with good ratings.  One didn't return the call, two must have wanted a simpler situation and declined to even come out to see my problem.  Toptec came out, gave an estimate in a day and did all the work I needed done.  They were very professional.  And they did all with a minimum amount of needed drywall work when finished.  I highly recommend their work.

"We are new homeowners and had a hole in our septic tank made of concrete block, which was sending wastewater into the foundation/basement of the home. It was my first time using Angie's List, and I would recommend Illinois Sewer and Drain to anyone. Joe and his team of experts solved our issue immediately at an affordable price. They even went above and beyond to install a sump pump in our basement to help with the rain water. Quality work!!"

"I needed to have a slip proofing put on the pergo for my dogs in addition to the replacement of a bathroom fan and a repair to my garage ceiling drywall. Daniel read up on how to apply the slip proofing for the pergo before coming to the house and recommended a nice ceiling fan. The price was very affordable and all of the work was done well. I am posting this review now because I came looking for him to do some more work in my house."

Basement Waterproofing questions, answered by experts

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.
