"The customer service was good. They showed up when they said they would, and completed the project early. However, they didn't do a great job paying attention to details when trimming the foam & cleaning up afterwards. I had to spend a few hours trimming foam they missed, so that drywall could go up without interference, and dealing with staples and foam on painted walls."

"We chose ABI because we were comfortable with their assessment, quote details, and ability to answer our questions thoroughly. We went with polyiso boards and cellulose as the materials. The price was very fair. The day they did the work, with Flo and Carlos onsite and part of the crew, they were focused, professional, friendly, and careful with our home and belongings. Any hiccups along the way were problem-solved and dealt with immediately. They not only left the inside clean, vacuuming after they removed the runners they brought, but made sure to check the outside of the house and swept the driveway for any small debris. The final check included a walk around the outside of the house. We knew they had to remove the siding to drill the holes to blow in the cellulose, but you would never know that the siding had been disturbed. We would not hesitate to recommend this company to anyone else looking for a fair and honest home insulation company!"

"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 FAQs, answered by experts

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels.
