"Warren did foam insulation to a gruesome crawl space and also installed a dehumidifier/fan to dry it up. He was very responsive, answered all my questions, was extremely polite, stayed under budget, excellent work done, and cleaned up every day. I m very pleased with all the work he did. I will hire him for more jobs. I highly recommend N.E.E. Construction and Spray foam."

"I could not have been more pleased by the work and the professionalism and the cost and the results. ABI was the first company to respond to my request for bids on the project. They were at the house within days of the request and were knowledgeable about putting insulation over light fixtures embedded in the ceiling. The attic did not have access from within or outside the house and they problem-solved this in a way that was a great solution. They lay down mats so as not to dirty up the carpets and stairs and they wore gear to protect themselves from the insulation. MY house was cleaner when they left than when they arrived. All of the people working on the project were professional and knowledgeable and the cost was extremely reasonable. For the first time this winter, my house feels like it can hold the heat. Looking forward to this summer, because I'm betting it will also improve my air conditioning!"

"Quality Insulation of Portsmouth did two jobs for me: They added blown in insulation to my attic last fall and installed gutters plus leaf guards this spring. Both jobs were excellently done at a reasonable cost. I would certainly recommend them and will likely use them again in the future."

Insulation questions, answered by experts

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

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.

Yes, insulating hot water pipes helps your system run more efficiently. This is especially true in basements in colder climates, where cold air likes to settle in. There are a few ways to insulate water pipes (foam is common) to keep hot water hot, reducing the need for your water heater to constantly heat the water in the tank or your circulator to kick on more than necessary.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.
