Great Lakes waterproofed my basement that had leaks on three of four walls. They also patched cracks in the walls . Their guarantee is great. I still had a small leak where the sewer pipe exited the basement and they came back and fixed it promptly and at no charge to me. I am very happy with this company.

Because I knew the problem I had was due to eaves trough overflow and not a ground water problem, I selected Great Lakes exterior sealing process before contacting them for an estimate. The representative who gave the estimate was very professional and efficient and the proposed cost was much less than I expected. The day the technician came to do the waterproofing, was so cold the equipment was frozen and could not process the material. There was 2 feet of snow on the ground also but he was undeterred and tried to thaw his equipment anyway. He was unsuccessful and had to schedule to return in two weeks. Before he left that day, he patched the cracks and holes inside the basement to be ready for the material to be pressured into the ground. Upon the return there was more snow but the temperature was lower. The job was completed within a couple hours despite needing to shovel a path around the house through 2 - 3 feet of snow. The outcome is that the basement has not leaked at all even though we have had all that snow melting and a couple early spring heavy rains.

The initial young man who treated the house was prompt and very kind. He went right to work and completed the job well. He checked on the interior wall throughout the process and cleaned up any material that came through cracks inside. A month later we had them come back out as expected to do some cement treatments on the interior of the walls where the walls were porous from the water that had infiltrated it prior. We had no other leaks until this spring when a spot at the bottom of the wall where it meats the floor brought in a small amount of water. They came out a week later and cemented the base of the wall from the inside and even applied a bit more bentonite on the exterior. We have seen a huge difference in the wall itself since the original treatment last spring. We believed that we would need to strap the wall due to a significant bow in the wall. Due to the treatment and the drying of the cinder the bow as actually decreased and the wall looks sound and strong. With a bit of patience with the process of correcting years of water damage to our cinder wall we see excellent results. Thank you.

My contractor believes the ceiling wasn't secured enough to handle the weight of the insulation. Cracks formed in the ceiling sand the drywall started separating from the roof joists in several rooms. I can't blame the insulation contractor but it would of been nice if they could of warned me about this happening.

They showed up on time and completed on time. They called on arrival and after the job was complete. They offered follow-up visits as part of their service and a follow-up phone call. Very pleased, thus far.

Fine - good crew, quick, efficient.

Salesman was prompt went through the whole basement inside and out.  Explained the procedure, application, product.  Explained the warranty, LIFETIME guarantee transferrable to new owners.
Worked with our work scedule when to come out. 
They did not leave the areas they worked on very well. 
They have yet to follow up to see how things are looking.

From start to finish, this was an excellent experience. The person who came out to do the inspection was knowledgeable, and did not pressure me at all. The technicians who did the work came a little early that I expected, so they had to wait a bit until I could get someone there for them, but this was not a problem. Office staff were courteous on the phone. Most important, their treatment worked. No more water in the basement. And they guarentee their work.

They came on the date as promised and finished the work promptly. Over all we are very happy with their work. I would use them again.

they were very professional and saved  me and saved me alot of money. it would have cost me over $4000 to install sump pump and it worked like a charm ni more water problems for me.

Good.

The quality of work was great. I had one spot that was still leaking and they came right our and fixed it. They were prompt. The did everything they said they were going to do.

They did a fine job, they did what they were supposed to do.  Their process is different than everyone else's. they inject clay in the outside. It worked for us. Everyone else wants to come in and tear down the landscape and tile. We could not do that because we only have a foot and a half between our property and our neighbor who is selling his property. That put us in a bind but they just came in with a big syringe and inject clay. It takes about 30 days to set , then they came back to fill in the gaps which were about every foot by the time they got done. It worked. They did what they promised. They guaranteed the work forever, it is transferable. I called three references before we started.

They did a great job except for cleanup. They dumped the leftovers in the front lawn and it took me 45 minutes to clean it up. They were very friendly and the gentleman who gave us the bid did a fine job. We were quite satisfied with the quality of work and I would recommend them; I just suggest you have a bucket ready so they can dump the leftovers in that instead of your lawn.

They did a very good job and they solved the problem. They had to remove a couple boards on the deck and they did replace them. I would recommend them.

They guarantee their work and they have been out to redo a few places since I have called them.
