Their service has completely went downhill since QSI was bought out. They refuse to stand by their products. Need their storm door handle replaced. They refuse to stand by the products that they use. Not only will they not cover it under warranty - they flat out refuse to assist or fix their products even as a paying customer. I still have thousands of dollars of windows to replace and I WILL NEVER RETURN TO QSI. I pity any one that turns to this company. They don't care about their products or customers. Bottom of the barrel company. Please go elsewhere
