nothing good to say about them
After the storms that came through this spring, we needed some roof repairs. We signed a contract with cornerstone, and then started getting excuses as to why they weren't there to do the work. After several weeks we spoke to a supervisor who ensured us that it would be taken care of. Several more weeks went by (with us calling once a week to check up) and they stopped returning our calls all together. Finally after two and a half months went by, we had to send a certified letter to the owner and company to break the contract so there would be no penalties. This is the worst company I've ever had the dis-pleasure to work with.
