"Exactly as the same as the first time I air sealed my attic in my previous house. Last year when we decided to sell our house I was inspecting my house as I would have if I was purchasing it. I noticed a small (1/4") gap between the master bathroom vent fan grill and the ceiling. I could not adjust it. Upon further inspection I realize it was because the foam that was installed when my attic was air sealed had expanded creating the 1/4" gap. I had that work done two years prior by Houle Insulation. I contacted Arne and inquired if he had any suggestions. His only suggestion was that he would correct the problem. Two days later he had two workers in my attic correcting the issue. Just like the first time, they were prompt and cleaned up after the work. I offered to pay, he would not have it. He said he should have noticed when the job was originally completed two years prior. There was no discussion or haggling, he simply said he would correct it. As impressed as I was with the lower energy bill, I was more impressed with how he and his team comported themselves. Also my house was more comfortable because the temperature was more uniform within my house. This year when we moved into our new house, built in 1992, the first thing I did was call Arne to air seal the attic. My choice of whom to hire for air sealing my attic was a no brainer, Houle Insulation. They also performed a blower door test. They also sent in all the information required for me to receive an energy rebate from my utility company. The best recommendation I can make is that when I decided to air seal our new home the first person I called was Arne. He made a wise decision to correct what needed with correcting without any questions. He did what should have been done, and therefore he got my repeat business and I was happy to give my business to him!"

"Paul bid our insulation job quickly and efficiently. He took before pictures and made recommendations so we could avoid ice dams in the future. We scheduled the job, he came on time, finished the work and took after pictures too. The cost exactly what was bid. Such a great experience. Also I goofed up the payment amount and they even handled that graciously. Will definitely hire again when we are ready to remodel our bathroom. Margaret and Franz R,"

Insulation questions, answered by experts

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

Yes, insulating your pipes can reduce plumbing noises because it dampens vibrations and reduces the transmission of sound, making your home a quieter place. So if you've ever been annoyed by the sounds of water rushing through your pipes or the clanging noises when someone turns on the faucet, insulation can help.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.
