"We had this company come to do insulation for our whole home - attic and walls (through Mass Save). Not only did they do what was in the original contract, but they also added insulation to our garage ceiling AND to an open wall that was being worked on for an unrelated home reno project! They did 3 days of work in 1 day & stayed late to vacuum and clean up. They were very professional, extremely efficient, and I love that it's a family operated company. Ivan, their office resource who helped book the appointment, was also a pleasure to work with throughout the process. We highly recommend using this company for any insulation needs."

"EZ insul did a great job removing old fiberglass under an addition of our home. Due to rodents we needed this removed and replaced swiftly. Jake communicated quickly and effectively. This allowed us to continue with our other projects. Additionally the EZ insul team rolled out drop cloths to keep everything clean and were very respectful of my home."

"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."

"Our central air conditioning system failed during the worst heat and humidity streak in more than a decade. When our AC contractor arrived to look at replacing the system, he pointed out that none of our 3 attics were insulated. We called Coleman Spray Foam. The put a highly knowledgeable rep on-site in less than 24 hours. One day later we received and signed their proposal. Crews arrived 2 days later and worked in unbearable heat and humidity in our attics until we had R50 insulation (needed for AC/Heat Pump). I would have them back in a heartbeat and highly recommend them for anyone in need of spray foam insulation."

Insulation questions, answered by experts

If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.
