"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."

"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!"

"We called Patrick to fix a sewer smell in our basement. After digging out a section of the floor, he found a pipe installed by the previous owner that had never been correctly attached to the sewer main. He and his crew worked on a Friday and Saturday to fix the issue. They jackhammered out the floor, dug up the old pipe and replaced it. Patrick was very attentive and showed me all the steps he was taking, carefully explaining everything that needed to be done. Cleaned up afterward and finished the job without issue. Highly recommended."

"Frank did an amazing job during our plumbing crisis. Our basement sewage ejector pump had burned out, causing a backup of waste. Frank and his brother heroically cleared out the waste and replaced the pump with a model better suited for the job. They were quick, friendly, and transparent through the entire process and their pricing is fair and straightforward. I definitely recommend calling Frank and SewerServ for any plumbing needs."

"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!!"

Basement Waterproofing questions, answered by experts

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

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.  

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.
