I have no idea on the prices. I just know that I think it would be too hard for him to be able to REALLY tell you an install price without seeing what he has to work with. I have seen it in the past------"Oh yeah your foundation will be fine! I can do it for $$." He just did not want to come out to the house. I asked for it in writing and that is the ONLY thing that saved me! Once he got here and saw where the water had washed some of the sand out he wanted to up the price. NOPE! Here is the writing quote that you gave me AND it stated that you had NOT seen the work area. So sad, too bad!
