DAMAGED SIDING and INSULATION: FSM cut a hole in my siding, leaving the insulation exposed for months (not resolved); DAMAGED FLOORING: FSM staff cut a large unnecessary hole in my floor (not resolved); FSM staff helped himself to what he wanted out of my yard, then entered my garage without permission, despite being banned from the property himself. POLICE and Ordinance had to be called. NOT SAFE to hire them. POOR quality: Seams not taped. Cuts in the liner. Grading NOT completed, leaving the entire project needing to be redone (not resolved); You end up doing the work: I had to dig my own crawl with their staff for 4 hours! REPEATED SAFETY RISK: FSM staff became aggressive on site and demanded more money from me. Spray foam, dirt, tools, and trash left behind on the liner. DUMP PILE left on the property. POOR COMMUNICATION: FSM either does not respond, or it takes weeks of nagging them. Even in severe instances of personal harm, they will leave you hanging. There is no difference in email, salesman, supervisor, foreman, text, calls, office- they are all the same and do NOT communicate with you or one another. BUYER BEWARE! DON'T do it! You pay a fortune to have this company destroy your property and cause you serious harm.

I hired Foundation Systems of Michigan to encapsulate my crawlspace. The crew they sent did the…read morejob in 5 hours, way to fast. I went down there to inspect and saw a horrible job. There were a couple rips in the material, the taping on the seams between sheets zigzagged; and this is on the factory cut edge that's perfectly straight. They used the spray foam to adhere the tarp to the cinderblocks. Some spots have huge spray foam globs that sank and pushed the material out creating air gaps. The only way that can happen is there is a critical shortage of fasteners holding the material up, I've seen less than 10 on the whole job so far. There are spots where the spray foam looks like melted cheese, its disgusting. The entire area has a layer of dirt and hundreds of spray foam turds along the walls. The two 'doors' they put on for $1000 were 2x4 and pvc board with 2 screws, absolutely unacceptable. When I called to talk to the crew they said they had swept out the area, I laughed and hung up on those liars. There is numerous work material trash left under there including a 2 tank spray foam setup. They also spray foamed 2 interior walls that were not part of the work plan and didn't need it. I had the supervisor come out to take a look and he pointed out more things wrong and said this needed to get made right. Guess someone forgot to write something down because when the next crew came to make repairs, they didn't have the materials they needed cause it wasn't written on the work service order thing. It's a month later and I still haven't received any before or after photos from them of their work but boy am I glad I went down there and took my own. I know it can be grueling work, but for something that is supposed to bring peace of mind about your home, this has been a nightmare. If you need go with anyone else

Formerly known as Foundations Systems 360 - note, they rebranded in March 2025 according to their…read morewebsite. Rebranded? Bought out is probably the case. It looks like US Waterproofing (USW) is a big player in IL & IN.... I had a huge crack in my basement wall that leaked bad enough that sand started pooling at the base of the crack. I had 6 estimates from $750 - $32,000, which ranged from just filling the crack all the way to interior & exterior foundation drains. USW was a mid quote, but the most bang for your buck and they offered a military, teacher, or first responder discount. With USW I got the crack filled/repaired, an interior floor drain dug from the crack to my sump pump (complete with a 90 mil wall liner), and a new battery back up sump pump installed. Their quote was reasonable, but installation of a new sump pump was the kicker for me and why I went with USW. They got me on the books the next week and took about 5 hours to the complete the job. What they got right: 1. They wrote into my quote that all exposed carpet from the entry of the house to the job would be covered. And they did an excellent job of this. 2. The team that was sent over was professional, friendly and let me watch and ask questions throughout the whole process. 3. Although they put up plastic walls around the work area, they warn you the process can stir up lots of concrete dust that will get everywhere. 4. My salesperson kept an open communication with me via text throughout, and after, the whole process. What they got wrong: 1. The exhausting sales binder they are required to go through with you. It's a 4 inch binder! 2. Although the binder is HUGE, they don't represent the final product transparently enough. I was quoted an access port to clean out the drain, but it stuck up 2 inches out of the floor, and they location they chose for it would've messed up my laundry set up, so I had them remove it (they need a flush access port option!). Another example is they did not have a great picture of what the wall liner looks like, nor did they have a physical example on hand. The salespeople should carry an example of the wall liner with them. 3. The 'crew boss' shows up and just walks right into my house and down to the basement, without announcing or introducing himself. I did not appreciate this, whatsoever. #2 & 3 of what they got wrong is why I took off a star, all in all, I'm pleased with the final product and what I paid for it.
