We had a new home built almost fours ago, now we have been having cracks in the dry wall. Cracks have been in the seams of the vaulted ceiling. We turned our problems to the registor of contractors they made our builder repair the problem now for the last three years. Their solution is to caulk the corners and seams but the cracks come back about 4 to 5 months later.What can we do to repair it right? We have had cracks in our dry wall the last couple of times they took out the drywall and replaced the area with new material but the cracks come back. We also have cracks outside in our stucco can these be filled in?
