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

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.
