"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"We had our basement waterproofed last year and were very happy. This year's project was adding two support beams. Again, we were very happy with the quality of the work and the people we dealt with. Both Gunnar and his team and Perfecto were skilled, efficient, and very professional. Highly recommend."

"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!"

"Arrived on time. Outside spigot had burst and water leaks into house when spigot is turned on. Required a new spigot and replacing some copper tubing in the basement ceiling. Worker wore booties and laid down a tarp so there was no damage to the basement, which is finished.  Took about 2 hours.Was very professional and explained everything.

"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 realized one of the water pipes in my upstairs bathroom was frozen- no water coming out. The other sinks/tub were fine. I called Four Seasons for an appointment based on Angie's List,  and was able to get someone that afternoon! (I was thrilled!)

     He came out as promised during the 4 hour window of time they said. He checked and found out that the pipe had defrosted by then. He then checked every sink and shower/tub in the house, including the basement. He patiently answered our questions on how to prevent this from happening in the future. It was reassuring to have it all checked.

      It was great to have someone able to look at all of the other water pipes in the house just to be sure it was ok. I will be calling them for future work.

Basement Waterproofing FAQs, answered by experts

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.
