We bought a Cape Cod style house in a few years ago and soon found out it was poorly insulated. I found out that Cape Cod style houses are one of the most difficult types of houses to insulate due to the many voids that are built into the construction. The house also needed a new roof so after researching spray foam insulation and talking to Brad the owner of Weather Seal Insulation and Roofing I decided it would be the best option. Weather Seal is one ,of the few companies that does both roofing and spray foam insulation. The advantage of which benefited us because while they were tearing off the old roof they discovered that the gable at the front of the house and over part of our living room, had no insulation. Brad was able to quickly come and spray foam that space so the roofers could continue their work. Now our living room is much warmer. Another advantage of spray foam insulation applied to the underside of the roof deck is that the insulation on the attic floor can be removed, which we had done, providing easy access to electrical wiring if it needs to be repaired or upgraded. When inspecting our house for a quote, Brad suggested spray foaming the basement walls, because a significant amount of heat is transferred through the walls. I was skeptical at first, but after thinking about it, it made sense, and with the added coat of protective white paint over the spray foam, I would brighten up the basement which needed to be painted anyway. Now my basement is the warmest level in the house, and the basement looks cleaner and brighter. Even my father in law, who has many years experience in the construction trades, was impressed at how well it looked. The whole house is noticeably warmer and the furnace comes on less often.
Brad was given a near impossible task after another contractor left me high and …wet… (insulation). After multiple walkthroughs to make sure he covered every scenario, and ensuring he had a step by step plan, his team executed a near flawless job. Incredible communication, incredible work ethic, and willing to go above and beyond to make sure I was happy. Count yourself lucky if you get the chance to work with Weatherseal and Roofing. Thanks again, Brad!
I am a Single Woman owning a home and found rodent damage on my roof. Upon searching for Roofing Repairs, Weather Insulation and Roofing Called back came right away after holiday weekend and came over at 6:45pm and stayed until repair was done. Then he found things that when I had roof installed they failed to do during insulation and also took the time to take care of that. I am amazed with this Company and Highly Recommend using this service. Brad I thank you for all your honesty and extra mile you took for me. I will call you if needing repair again for sure. Thank You

Had the basement rim joist air sealed/spray foam insulation done at my home yesterday and the technician Quintin did a fantastic job. Working with Matt was great and I would definitely recommend this company.
We needed our attic insulation replaced due to rodents. Contacted Matt and knew i made the correct call right away. Justin came out to inspect the attic and determine several problems. They were able to schedule us within two weeks. The very professional crew came out and kept everything as clean as when they got here. Found and fixed a few problems we didn't know about and finished the whole job in less than a day. Attic looks like new, all the fans are vented properly and things are sealed up as they should be now. Price was in line with other estimates but I know these guys do more than other companies do for the price. Would definitely recommend this company if you need new insulation or a complete replacement like we had done. Communication was great also.
Matt and his team were a pleasure to work with, all were very professional. We had vermiculite in our attic, and they were extremely professional on how to remove it without it getting in the house at all. The vermiculite did not once enter the house once. If I need to have more insulation work done, I will certainly work with Matt and his team again.
