Permaseal has been very thorough and knowledgeable about everything I needed to be done. While it was more expensive than I would have liked, I appreciate the peace of mind that PermSeal’s warranty and longevity provide. Andrew Casper was our consultant and he took our long decision process in strides. We asked lots of questions and he answered them professionally and patiently throughout the process. Isiah and Manuel did the work for two days at our home. They were respectful, courteous, knowledgeable, and professional through the entire process. They also answered all my questions, leaving me with no uncertainty on how things would work. I would definitely use them again.
