Customers say: Super punctual

"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."

"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

"Bob is so easy to work with. He quickly gave a reasonable quote and came to install my new ducted range hood within a week and completed the job in couple of hours. He and his brother were just pros. It’s also very convenient that you can pay him with a credit card. I highly recommend Bob for your home projects. I’ll definitely keep him mind for my future home projects."

"We can't express how thrilled we are with the remodel of our den/bathroom. Eric and Tom took great care in making the outdated room a beautiful space that we look forward to using. Their work ethic is outstanding. The job was done quickly and with care, and their pricing was excellent. We'll be using them again in the future. This is a "go-to" company! A+++"

"We are beyond pleased with the services provided by Hughes. Their workers were exceptional. They showed up on time, were polite, explained the process as the job progressed, answered all our questions and were extremely respectful of our home. They cleaned up as they went along and were very quiet. This was not an easy job. The slant roof and small space must have made this job all the more challenging because you can't stand up straight. The guys still managed to get it done within the time frame they had committed to and never once complained. The works looks very professional and our home feels so much more comfortable than it was before we insulated."

FAQs for insulation service projects in Hanover, 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.
