These guys were good to work with. I did some research and found them to be the only company that has the tool and equipment to do this kind of work. My garage floor has several large cracks and I was starting to get mice under the car door due to the gaps from sinking. Someone from there sales team came out and gave us a quote. They took a deposit for the work and scheduled an appointment. They didn't show up for the first appointment they scheduled but did call to say that they could not make it. The second time they came, the workers explained the process and told me what they where going to do. They said they could not guarantee it would turn out prefect. They suggested some other ideas of what could be done to fix it but didn't offer pricing for these options. After they left I was not completely satisfied with the repair. I called in to voice my concerns and they said they would send the guys back out. I almost wish I would not have had them come back. After the second visit the floor seamed worse. Wont hire them again but I think what they are doing is unique and I say give it a try and see what you think.
