Get matched with top foundation, basement or crawlspace waterproofing / encapsulation pros in Northbrook, IL

"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."

"I just bought a house in Glenview. I was looking for a company that could install a drainage solution to one side of my house. The grade runs towards the north side of the house causing excess water runoff and potential seepage into the basement. I did my research and found ULB-DRY Waterproofing. I have to say that the entire process was absolutely flawless. Their estimator came out to assess the situation and provide solutions. They had to come out a second time to perform a site survey to make sure their solution would work properly (making sure there was enough pitch from the front of the property to the back to drain the water). Once everything was assessed we scheduled a day for their crew to come out to perform the work (installing a french drain to move excess water build up away from the side of the house). They also connected one of my gutter downspouts to the pipe to drain that water away also. The crew was very professional, hard working, and technically sound. Not many companies have all these attributes. They really knew what they were doing. This company is awesome."

"Louis was concerned with Doing The Job Right ! He took his time and was very willing to explain what he was doing. I highly recommend LA Basement Waterproofing"

"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 have worked with Jeff Kowalik from Perma Seal for many years. As a Realtor, I have recommended them for all kinds of jobs. The work I have seen them do ranges from filling cracks to drain tile systems to vapor linings and even straightening out a bowed wall on a home. I have a cinder block basement in my home built in 1921. In order to keep moisture and ultimately mold away, Perma Seal installed a vapor barrier, a membrane, around the whole inside of the basement. And then with their suggestion of the dehumidifier, the basement is ready for finishing. First, their sales department is terrific. I use Jeff Kowalik, and he is knowledgeable and instills confidence with his knowledge of what is needed. The workers are on time, organized and get the job done. My personal experience was a 10+. I would highly recommend Jeff Kowalik & Perma Seal for any of your waterproofing needs."

"They did a great job.  They came out a couple of times to make sure they knew what they were going to do and explained everything to me.  When the time came for the job to start I wasn't able to be on site during the work so I gave them the keys and they did what needed to be done and I was very pleased. It took about four or five days. I can't say it enough, I'm still pleased whenever I go to the basement."

"My basement experienced water flooding in multiple locations after very heavy rain. A well-known company provided an estimate of 14K for floor tiles, a new sump pump and told me the bathroom would have to be remodeled because of the floor tiles. Allegro Design came out for an estimate and told me that they would have to cut the drywall in the rooms because they could not diagnose the problem by guessing. After hiring them, they cut the drywall which revealed there were huge wall cracks by the windows. They sealed them from both inside and outside. They dug up my yard and applied liquid rubber and cleaned up so well that you could not tell they were there. They also cut the drywall neatly so we could reattach them ourselves later. I appreciate their honestly, fair pricing, cleanliness and the fact that they did not try to sell me on an expensive new sump pump or floor tiles. I highly recommend them."

"I found this company to be honest and very knowledgeable about foundation issues. They not only found the problem and fixed it, they did so without leaving a mess. 1 week after they made the outside repair, no could tell were they dug the hole and back filled it."
