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

The process was great - Andy and his crew did a fantastic job! How nice to have a company show up on time fully prepared to do the job and keeping us informed of what was happening every step of the way. I would not hesitate to recommend this company!

HIGHLY RECOMMEND! My…read moreinteraction with Mr. Sponge Waterproofing Inc. has been nothing short of satisfactory. Honesty, dependability and quality workmanship are qualities I look for when doing business with companies. Mr. Sponge has met my expectations in those regards. I was first introduced to the company in 2018 when I inquired with them about the sealing of foundation cracks in the basement of a property I owned at the time. I submitted an online request for consultation and within hours I received a response from the owner, Sherrill Dean Teaster. Although my problem did not require Mr. Teaster's services, I was very appreciative of the time he took to provide an informative, detailed explanation of how my problem came about and the steps I could take personally to bring about its resolve. Mr. Teaster's empathy and honesty were admirable and left an everlasting impression on me, which is why I sought his services just recently. I observed Mr. Teaster as he completed my service repair and it is apparent that he is a master of his craft as he performed with the level of care, accuracy and thoroughness you'd expect from a skilled professional. My customer experience with Mr. Sponge has been gratifying and I expect the results of their work to be just as pleasing.

This time Dean came out and did a great job. 22 tie rod leaks and 2 cracks were repaired. Dean also gave me recommendations on companies to call for the remaining leak that Dean's company can't handle. Mr. Sponge's scheduler and Dean were able to accommodate my having to care for my Mom and being available to assist with showing Dean what I needed done. Mr. Sponge is a great company.

Why would a customer pay for a job that is not done. 2nd visit they had the very same trouble with injection gun, and then spilled brake fluid on my newly sealed driveway. Apparently brake fluid is used to clean the gun. 3rd visit they finally had equipment that actually worked. But I would not let them apply the seam sealant because it was gray and did not match my colored stamped patio, in which the sales representative said they would at least try to match the best they could. Gray was not even close. 4th visit they applied the sealant and added the colored sand to surface to match the patio. On the final visit they only offered $100 discount for my stained driveway. I reluctantly agreed just to get them out of my yard. They should of offered more because of the four visits to do a small job and the permanent stain on my driveway. My father was asking if Ayers should level his sidewalk, my response; Heck no, find someone else. I do not recommend this company at all. See photos of permanent stain that they didn't even try to remove, they left it for me to clean the best I could.

Update to Complaint/Review HomeSpec Waterproofing and…read moreFoundation Repair I am writing to provide an update regarding my experience with HomeSpec Waterproofing. In 2024 I entered into a contract (which I paid cash for) with HomeSpec to have my basement waterproofed and a sump pump installed. Over the following two years my basement continued to take on water after heavy rainfalls. After multiple visits that yeilded no answers and a periood where communication stalled, I posted a negative review to express my frustration. Shortly after posting, HomeSpec reached out and sent a team back to my home. Thats when management representative Brian stepped in and took full accountability for finding the root cause. He used a practical methods to track the water flow, he placed paper towels around the perimeter to pinpoint the entry point and found it. After the next rain he had his crew to remove the drywall and insulation to expose the hidden leak. Once the leak was identified, the crew repaired the issue. As of 9/2/2026, HomeSpec has restored my basement by installing new insulation, putting up and painting new drywall as replacing my electrical fixtures in the area where there was water damage. While the overall process took a long time and required significant peristance to reach a solution, I want to extend my sincere appreciation to Brian for his professionalism, determination to making things right, Hopefully the issue is now resolved, and I will be monitoring the basement during upcoming rainfalls to ensure the fix remains permanent. I have to give credit where credit is due. Thank You Brian.

High strength epoxy injection was chosen since there had been no water leaks and both inductive and thermal imaging confirmed there was no moisture concern in any of the basement walls. Throughout the entire process HomeSpec were very professional and courteous, from their office staff through to the field technicians.

The cracks were repaired proficiently and the work site was well cleaned and all debris removed before departing. Overall 5 stars.

Michigan Basements absolutely delivered for us in Northville…read more For a while we tried to "solve" our basement water issue with epoxy crack injections. It would look good for a bit, then fail again, and we realized we were basically putting a bandaid on a bigger problem. We finally decided to stop chasing it and do full waterproofing with Michigan Basements. They installed an interior drainage system tied into a new sump pump, and finished it off with a vapor barrier on the walls. From the first visit through the install, the team was professional, clear about what they were doing, and didn't oversell anything. The work was done cleanly and efficiently, and you can tell they take pride in doing it the right way. I also purposely waited to post this until we had real storms and heavy rain so I could honestly say the system works. We've now been through multiple downpours and the basement has stayed dry. On top of that, everything is backed by a full lifetime warranty, which gave us a lot of peace of mind. If you're tired of quick fixes and want it handled the right way, I highly recommend Michigan Basements.
