Customers say: Super punctual

"We hired McLaughlin & Williams through the MassSave program, which had performed an energy saving audit for our house and made a clear checklist of work to be done that we could confirm with the contractors. We scheduled the job months in advance, but they were flexible when we needed to reschedule at relatively short notice. Jay and his team showed up early the first day, and clearly laid out the work they were going to do, and why. When weather and scheduling issues prevented work on the second day, they sent a double team on the third to make sure everything got done within the scheduled time. In general, the workers took good care. The exterior siding that was removed for injection was cleanly replaced, though some shingles that were already damaged or waterlogged were a little worse off. Despite all the dust that comes with blown cellulose, there were only a few traces inside. They also made sure our cats didn't get out. During the course of the job, they also found that there was already some wall insulation in one section of our house, and only charged us for the work done."

"Rob was a great communicator and his promptness and knowledge were one of the main reasons we went with him over a slightly lower estimate we got. His sons did a good job of doing the work we required, which was messy work, and they left the place in pretty good shape with just some leftover bits of insulation here and there. If I have any additional insulation needs, Calnan would be my first call."

"I could not have been more pleased by the work and the professionalism and the cost and the results. ABI was the first company to respond to my request for bids on the project. They were at the house within days of the request and were knowledgeable about putting insulation over light fixtures embedded in the ceiling. The attic did not have access from within or outside the house and they problem-solved this in a way that was a great solution. They lay down mats so as not to dirty up the carpets and stairs and they wore gear to protect themselves from the insulation. MY house was cleaner when they left than when they arrived. All of the people working on the project were professional and knowledgeable and the cost was extremely reasonable. For the first time this winter, my house feels like it can hold the heat. Looking forward to this summer, because I'm betting it will also improve my air conditioning!"

"I am VERY late in writing this review, but as I was in the Angies List site I thought I'd put this review in. I can't say enough good things about Vaillancourt Roofing. I had a leak in my roof, winter was coming on and no other roofer would call me back. As an act of humanity Adam and Dave drove down from NH to look at my roof even though they don't do repairs in my area - Carlisle, MA ( I understand they could possibly do roof replacement in my area). They came when they said they would and they found the leak quickly. The leak was from my chimney. They aren't mason's necessarily, but they put a temporary fix to the chimney, so I could rest easy until the next Spring when I could address it. They didn't charge me and were done in about an hour. I wish my roof itself needed replacement, if it did I'd all them in an instant. Just wanted to put in this review as I owe it to these great folks."

Insulation questions, answered by experts

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

There are two reasons why cellulose insulation repels rodents (and insects). First, the insulation has been treated with boric acid, which is a natural pest-repellent. In addition, the loose-fill style of cellulose creates less-than-ideal conditions for mice and other rodents to nest and burrow, helping to keep them at bay.
