The main problem is that they don't return calls (from months to years) and promise they will. I have been promised repair work on concrete deficiencies for two years now and the best I've received are empty promises. I'm not sure if they just over commit and can't get to anything (yet say they will) or if they simply choose to ignore customers.
The guy who used to do their concrete work (who did my slab two years ago) did a poor job on a few things:
1. joint between stub wall and slab leaks (guaranteed by him it wouldn't)
2. finish on one wall full of holes (admitted inexperience guy did vibrating)
3. parts of slab spalling.
After many calls I finally got a visit from Jason who's crew did the work and he promised to fix these problems. That was the summer of 2011 and that was the last I heard of him.
I've had dozens of calls to the company and sent them copies of my invoices. Out of that I only had two conversations where they said they would look into it. Then complete silence.
Not sure what to do now. They all seem friendly and helpful when I finally talk to them, but the lack of follow-up and service is appalling.
Go with someone who actually knows concrete work and is capable of providing customer service; not these guys.
