"The team from McLaughlin Weatherization, who completed the work from my Mass Save Program energy audit to install insulation in my attic was AWESOME! They were a team of 3, who ensured the job got done efficiently and well. Professional, courteous and personable! I was very pleased with how they entered my home, treated my home and me while in it and when they left they even brushed up the very last of any dirt they might have brought in. I cannot rave enough about how great the experience was because I was able to work downstairs and stay out of their way but they definitely went above and beyond in my opinion! I didn't know the front door would get a package of weather stripping too. So while that was nice, the guy in charge of the team of 3 not only removed the old to install the new, the front door closes properly now! I cannot thank you enough for this small act of kindness (even if it was fixed with the new trim) because I had been so worried about my kitties getting out one day because the latch would not catch to keep the door closed. Also, the senior member leading the team demonstrated his years of experience and knowledge and explained everything to me and answered all my questions. I highly recommend this company as a partner for Mass Save and I would personally pay them for any future work needed if not covered by Mass Save."

"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."

"Peter was extremely flexible on when the work was to be done. He "listened" when I spoke about what I wanted done and he made sure I was happy with every step of the job. I wish all contractors were this attentive! I would recommend Peter to anyone looking to improve their homes insulation."

FAQs for insulation service projects in Dover, MA

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
