We had 8 windows replaced, 5 of them large panels. Given the pandemic and supply line issues, response time for installation was good. Upon completion, Abby's quality satisfaction follow up was conducted and they found several issues that needed attention. As a result, several areas were redone to their and our satisfaction. We are very pleased with the type and quality of the windows. As a result, our rooms are now warmer in cold weather. Their quality standards and follow up are exceptional. We are fully satisfied.
