"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."
