"Our central air conditioning system failed during the worst heat and humidity streak in more than a decade. When our AC contractor arrived to look at replacing the system, he pointed out that none of our 3 attics were insulated. We called Coleman Spray Foam. The put a highly knowledgeable rep on-site in less than 24 hours. One day later we received and signed their proposal. Crews arrived 2 days later and worked in unbearable heat and humidity in our attics until we had R50 insulation (needed for AC/Heat Pump). I would have them back in a heartbeat and highly recommend them for anyone in need of spray foam insulation."

"From start to finish Ecomax was a wonderful & professional experience during a much needed insulation change from fiberglass to spray foam. I'd hire this team again and want to thank them all, especially Herika who was extremely knowledgeable & on top of the entire job. She returned phone calls & emails answering questions promptly. Great job!"

"MEL did a spray foam insulation of my attic last fall. This was a complex job as it required careful co-ordination with separate HVAC and electrician teams (we were also replacing HVAC, which is located in the attic, and upgrading our electric wiring infrastructure). The MEL team was a blast to work with and did an outstanding job - and I don't use such adjectives freely when describing contractor work around our house. First, Mo went to great lengths to assess our attic and propose the right solution .. for example, during the proposal process, he was the only one out of 5 contractors who crawled into a narrow space in a distant part of the attic to inspect it. Second, the work the team did, was truly first class .. we went from massive ice dams before to literally not a single icicle hanging from the roof last winter! I was also very pleased with the clean-up they did, with two rounds of detail-like vacuuming of the attic. Third, MEL's co-ordination with HVAC and electricians was very effective, in spite of major hiccups with our HVAC contractors. Finally, these guys really understand and live the concept of 'customer focus'; their communication is very professional, and it is not unusual that they respond within an hour! The only weakness I would point out was their carpentry subcontractor (Adilson), who left a small piece of work unfinished and I felt he overcharged us for a minor change order. This spring, I hired MEL again to do a smaller project involving rim joint insulation in the basement. Josue led the project, while Mo was on vacation. The experience was as positive as the attic experience. I would recommend MEL without any reservations."

"Roland did an excellent job. He explained the things I needed and those that I didn't. He was right on time and finished the job in the time he stated. He was very professional and knew what he was doing. If you are looking for a straight shooter without any of the sales frills (and the larger cost) then Sav-On Insulation should be your choice."

"Following a MassSave audit, about 6 months ago Hugh's insulated our garage. We were very pleased with their work. When we decided to do additional work and insulate our attic, I called Tom again to arrange for Hugh's to do the work. It went very well. I would definitely recommend them to others."

Insulation FAQs, answered by experts

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.

The best type of insulation for your home depends on your specific needs, climate, and the area you are insulating. For new construction, structural insulated panels are a highly energy-efficient option that is easy to install during the building process. In very warm climates, reflective insulation can be a cost-effective choice. For cold climates, fiberglass is an excellent option due to its high R-value and resistance to settling over time. Spray foam works well in humid environments because of its moisture-resistant properties. For standard attics, loose-fill, spray foam, or blown-in insulation are all suitable options.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.
