"They did an incredible job. Took out all the blown in insulation and spray foamed whole attic. Making it a useable space for storage and helping to regulate the temperature in our home. Will be calling on them for future projects."

"Larry, President of Coastal Isulation was extremely responsive to my calls, questions and a quick turnaround on the estimate. Larry was able to wor with me on the price and gave me a price that worked with my budget. I was impressed with the timeless and responsiveness from Larry. The insulation was complete within one day. Larry even followed up with me a few days later to make sure I was happy! (dont ever get this from contractors!). Larry even sent me a nice hand written note thanking me as a customer."

"E&Bs gave me some possible options. They did an excellent job on replacing my floor to waterproof vinyl flooring. Would definitely hire for new services."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"They custom make the windows and Fed-Ex them to you. We installed them ourselves to save money. Once we put them in, we couldn't hear outside noise anymore. It made a world of difference. I think it has also helped insulate my home a little. For the cost, I think it would have been twice as much to have the windows replaced."

"EXCELLENT PROFESSIONAL SERVICE! Called them cold on a Sunday night from my DC home to repair many shingle caps that had blown off the peak of our roof of our townhome in OC- I could see daylight from the attic and the insulation was wet. They were on my roof Monday morning, in the rain, fixing it completely. They took before and after photos on the roof so I could see exactly what they had done. They also replaced a cracked vent pipe boot.
Very easy to deal with, good communications, knowledgeable and professional.

"Due to the weather they have only been able to complete the interior portion of the house, however, they have been remarkably responsive. They have been great to work with and everything I've requested they said they could do. Even spraying areas around the house. Both the rep and the tech were very friendly and answered all of my questions.
