"I would highly recommend John P. Insulation. I got three quotes for my insulation job and they were the most professional during the estimate. They provided pictures of what they were going to do. They fully explained the job and what I should expect. The quote was fast and equal or lass than the others. On the installation day, they arrived when they said they would, covered my floors and completed the work exactly as they said they would. I had them foam seal, blow in insulation, install soffit vents and vent a bathroom fan. You will not be disappointed in the quality."

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."

"I highly recommend Green Way. The folks from Green Way were professional and they delivered high quality work at a great price. The work involved applying foam to exposed roof deck in the attic, and applying blow-in insulation between unexposed roof deck the interior walls. I'm very pleased with the outcome."

"Rob was a great communicator and his promptness and knowledge were one of the main reasons we went with him over a slightly lower estimate we got. His sons did a good job of doing the work we required, which was messy work, and they left the place in pretty good shape with just some leftover bits of insulation here and there. If I have any additional insulation needs, Calnan would be my first call."

"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!"

Insulation FAQs, answered by experts

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

Energy-efficient homes generally have higher appraisals and appeal to buyers.

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.
