"Highly professional and extremely accommodating. There were bats in my attic when they went in to redo the insulation. They calmly (as they could) told me the situation and came back at a later time with no added cost. Did an excellent job, and had a incredible attitude throughout. Cannot recommend enough. Thank you!"

"Everyone was very courteous, on time, and the personalities of the entire team were amazing. Edgar and crew made this project very easy and we are very very very very pleased! AJ kept us updated and was very helpful as well with the project. I will keep them in mind for our next projects and would definitely recommend to our friends and family members. Also Iâ ve already noticed the air quality difference from our new roof and now insulation. Job well done all around"

"I liked that the first questions we were asked was "Have you had a home energy audit done? Did you know you can get a rebate on your insulation project?" Before even knowing the scope of our project, they were looking to help make it more affordable for us."

"Perfect wall LLC service was amazing! They went over the job with me and explained everything and taught me a thing or 2 about insulation. After the job I went to look at the results and it was exactly how he explained it! They use measuring templates you can see the actual depth of the insulation in all parts of the attic which was awesome. The vent out the exterior wall was so perfect I couldn?t even find it unless I really looked. Everything came out perfect they took the time to clean up very well also which my wife was very happy about! 10/10 would use again."

"Recently had my attic insulated by Best Homes. Chris and his crew were professional and very efficient with their work. They insulated my attic within a few hours and left my house cleaner than it was before they got there. I wouldn't want the job done by anyone else."

Insulation FAQs, answered by experts

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.

Insulating your ducts offers several benefits, including:

  • Improved energy efficiency: Duct insulation prevents energy losses, reducing heating and cooling costs.

  • Cost savings: Lower energy bills make insulation a cost-effective investment.

  • Environmental benefits: Enhanced efficiency reduces your carbon footprint.

  • Consistent comfort: Insulated ducts help maintain a stable indoor temperature.

  • Better indoor air quality: Reduced allergens and pollutants improve air quality.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.
