"We highly recommend US Waterproofing. Unfortunately, after repeated issues (we’ve had water getting through a basement door, water backing up from drain/sewer pipe, foundation cracks – all which were addressed) we now have had issues with hydrostatic water pressure delivering a great deal of water to our finished basement. Only one solution – drain tiles and sump pump installation. US Waterproofing was outstanding, every step of the way. They communicated clearly what was needed, and much to our surprise, what was not. They did not ever try to sell us anything that was not needed – only what was – installation of drain tile, window well drains, sump pump, and all work related. All of the crews involved were outstanding – in particular, the crews installing the drain tile and sump pump. The supervisor clearly and concisely explained every step – and when issues arose, they were dealt with promptly. The teams removing drywall and reinstalling also did very good work, and were very responsive. Everything was done correctly, and on schedule The work is now complete – and the basement is back to normal. I commend USW on all facets – they explained everything, did not try to oversell anything, and were responsive to issues as they arose. All the way around – sales, customer support, install teams – outstanding. If you have an issue with water in your home, please consider US 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!"

"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

"I own a multiunit building and in the last year I cannot tell you how many times I’ve had contractors not show up, give a quote and not return, overcharge, not complete the work, complete the work poorly, make excuses, waste time, or refuse to do business on the south side.....it’s been very stressful. So much so that I considered selling the property because it was so difficult to get the help I needed. I decided to keep trying and found HomeAdvisor. They recommended Aco/Daniel. We talked on Thursday evening and he said he could probably do Tuesday. I wanted to cry because I had just hired someone who didn’t complete the work but told my tenants he’d be back Saturday and his was like the 4th guy. So I really wanted someone to show up and get it done. Daniel said he could do Sunday if I really needed. I did. We agreed on a price and he said to let him know. I decided to go with him and we confirmed via text. I kind of expected him not to show based on the number of bad experiences I’d had. That’s how done I was. Sunday morning, he texted to let me know he was on the way. I arrived at the building and walked through unit by unit with him and Peter. They understood what I wanted and kept asking what else to be sure nothing was missed. They left to get materials. I left to get doorbells. When I came back they were almost done with a door on one floor. Then they moved to the next floor. It was then that I realized I had been holding my breath. This was working out! The work looked good. They were going the extra mile. They were professional. They were working hard and focused. They asked if I was happy with each item they completed before moving on. Even my picky tenant was happy with the work. I can’t tell you how pleased I am with these guys and their performance. This is the first time I’ve felt like I could rest because my tenant’s checklists were completed. Some have been waiting since August. The work is great. Their attitudes are great. I told Daniel that I’ve never been so happy to pay for something. I cannot wait to recommend them and they will be the first people I call in the future. Thank you guys so much."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Waukegan, IL

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
