About Us

We used Northern Illinois Waterproofing for some issues we had. My husband and I highly recommend them. Matt, the owners son is very knowledgeable and went above and beyond for us. They were out the very next day after I called. Dawn, the office manager is very sweet and personable. What a great experience!

I found water in my basement after a heavy rain coming from a wall crack hidden by the previous owner. Northern Illinois Waterproofing was able to fit my "small" project in a few short hours after my call as they had a crew already in my area. Excellent customer service, a lifetime warranty on the repair, and high quality job done faster than I could have hoped for!

We had a small crack in our basement wall. The quote process was very simple and efficient, asked for some pictures of the job area and got a very reasonable quote a little while later. Excellent next day service. The very experienced technician came an did a very professional job sealing the crack. Would definitely call back or recommend.

Northern Illinois Waterproofing is an excellent company. They are very knowledgeable, efficient and professional and their prices competitive. This is the second time I've used them and both times they exceeded my expectations. I highly recommend them.

NIW has done multiple crack repairs for us over the years. We have been very happy with their services. They recently installed a new sump pit and pump at our newest home. They are friendly, fair, honest, and they stand behind their work. I would highly recommend them.

Absolutely wonderful experience. We simply needed an old foundation crack re-sealed, it was a minor leak. Got a second opinion after US Waterproofing tried to bleed us with major repair - tearing out landscape, drywall, and air ducts. So glad I found this family run business - came out a day after calling, gave a super reasonable quote that was minimally evasive, and had it all said and done within a week. Great quality of work as there we major rain this week and not a single drop of water in the basement. My wife and I would strongly encourage everyone use this company. If it was possible to give more than 5 stars, we would in a heartbeat.

Called a bunch of places, these guys were the best. Dawn was amazing and so easy to work with. She was so helpful and patient with all of my inquiries. I discovered water in my finished basement shortly after buying the house (which was marketed as having a dry basement.) I wasn't sure what to do and after a year of weighing options, went with Northern Illinois Waterproofing. They could have easily taken advantage of my lack of knowledge but instead educated me. They proceeded to fix the water problem at a very affordable price. We have had some heavy rains since they have been out, and there has been no water. I honesty wish I could give them more than 5 stars. Outstanding.

Used them for window well repair. Excellent and reasonably priced.
