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

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.
