"I would highly recommend John P. Insulation. I got three quotes for my insulation job and they were the most professional during the estimate. They provided pictures of what they were going to do. They fully explained the job and what I should expect. The quote was fast and equal or lass than the others. On the installation day, they arrived when they said they would, covered my floors and completed the work exactly as they said they would. I had them foam seal, blow in insulation, install soffit vents and vent a bathroom fan. You will not be disappointed in the quality."

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."

"Jacob and his team were great ! Everyone was super nice. I felt very comfortable in what I was told in regards to what needed to be done. After talking to many different insulation companies this was the only one that knew what I needed done and was able to do it at a great pirce. They managed to finish same day which was amazing. The results are so nice ! We didn't know what to expect as the end result since this is my first time dealing with insulation problems. But everything looks great !! I will definitely be going to them for any future projects. A million thanks to them ! I highly recommend these guys for your insulation needs. A trustworthy and hard working company."

Insulation questions, answered by experts

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process. 

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.
