This contractor filled cracks & seal coated our driveway November 15, 1907. The next day the sealant & most filled cracks washed off our driveway and onto our lawn, killing the grass. The contractor was paid in full on 11/15. I called J&R the next day and he refused to return and repair the work or refund our money. He said he would return in the spring and reseal the driveway. We haver called J&R at least five times since May 08 and our calls are not returned and they haven't repaired their defective work, material or poor workmanship.
