"The roof and trim were done, and look great. But I have a couple of issues .The crew was very unfriendly. I came out just to say hi, and they sneered at me and walked away without a word. Also, after they left I found out that they apparently cut an electric wire as I had a tripped breaker and now some of my electric baseboard heaters don't work. This was in an area where they replaced sheathing material right over my breaker box. I contacted the rep, who acknowledged my issue and I am waiting to hear back."

"Perma-Seal was out to insulate my attic this week and did an excellent job. David did a thorough inspection, explained everything, answered our questions, and even told us that we didn’t need certain work that we thought we needed. He was very honest, polite and personable, and gave us a fair quote with some options without being pushy. Luis and his crew began the work two days later. They were prompt, courteous, professional and knowledgeable. Luis explained how the project would be done and shared progress photos with me along the way. He even curtained off the area around the attic ladder to contain any waste and cleaned up everything perfectly. I would highly recommend Perma-Seal to anyone who is considering their services."
