"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."

"Hugh's Energy is a quality company and it starts at the top with owner-President, Tom Dromgoole. Tom made a site visit to my home to discuss details of the insulation including the process, timing, and outcomes; he answered all of my questions. He also came the day of the insulation to check on how things were going. His crew, led by Parris, was excellent - knowledgeable, efficient and clean. If you are considering insulating your home, just call this company and save yourself time."

"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

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.

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.
