Agreed upon price, than once started said he underestimated the price and want to re negotiate, we discussed, I agreed for an upgrade but never got anything I was promised. No crack filling, only got a light coat of sealer, they left, promised to come back and never did. I waited two weeks called them and got BS from him.. Said they promised nothing and they were four people and I was one, since all I had was a phone number, have to track them down before I pursue taking them to court.. Late FYI, part of sealer from first rain has already washed off, think they water theirs down a lot, so beware, and they do look more professional than any of the others I have used over the years.. Maybe I should have taken that into account; they were way to clean for this type of work.
