"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!"

"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"

"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 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

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.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits
