Hi Lesley it doesnt sound like you have had a good quality job here, it should be ok but fibreglass installations during adverse weather conditions are never recommended and patch repairing at 3mths old? . the problem lies in the fact these materials are avalable to all with either none or minimum amounts of training, always seek out quality time served firms and check up on their referrals.
