"Coleman did a wonderful job on our remodel. They did spray foam on the roof of the entire house and installed bats to insulate the walls of our demo'd side. They also had to remove old bats in half of the attic. They were very clean in the disposal of the old insulation and clean up of the overall job when they were done. Communication was great from the start...Shant was very communicative from the initial estimate through to the completion of the job. They were very competitively priced I'd recommend to anyone looking for an insulation contractor."

"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."

"I was plagued with recurring ice dams in a few areas of my roof. After investigation, it was discovered that the insulation in a few visible areas was sub-par. Roland came in and quickly spotted the problem areas. He assured me that the could fix these problems immediately. He used a combination of rearranging existing batts, blown-in fiberglass and spray foam to seal the attic space, over the course of two visits. He's extremely personable and always called me back or answered the phone right away."

"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."

"We called Sean with New Found Construction and he personally came out and gave us a quote to insulate our attic and the ceiling in the unfinished part of our basement. His price was far more reasonable than other quotes we had gotten and seemed to offer a more complete job. It all came out AWESOME and we can absolutely feel a difference in temperature in the house (especially my office above the unfinished basement which used to be an icebox in the winter) and the heat kicks on a lot less. We have already planned to have him and his crew do other jobs around our house. Two thumbs way up!!"

Insulation FAQs, answered by experts

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills.
