"Cardinal Insulation was great! They cleaned out all of the old insulation from my attic and then did a new blown insulation in my attic to R38 and now the house feels so much more even temperature throughout. Very knowledgeable and easy to work with. My FPL bill went down around 15% as well as the AC does not need to work as hard now."

"Excellent service from true gentlemen! Florida Insulation Systems sprayed foam insulation in both our main house and our guest house. They did a fantastic job and were incredibly clean throughout the entire process. Their pricing is very fair, and Jonathan is a phenomenal communicator. What impressed me most was their follow-up care. Even a year after the installation, we reached out to ask them to check on a few areas. They came right back out and took care of everything meticulously. I highly recommend them for their outstanding workmanship and dedication to their clients!"

"I received two phone calls New year's day from two different companies. one of them said they would get back to me later that day with an estimate. the other one called left a voicemail and sent me a text message. so I called Craig from American insulation back. gave him the measurements of my roof over the phone he gave me a price over the phone of what it would cost to do it. I knew the pitch of my roof how many square feet my attic was etc. without going into specifics on cost and price he was $200 less than the estimate I got from treasure coast. love it insulation didn't call me back until the following day. so I scheduled appointment for January 2nd. two guys showed up I still had stuff in my attic while they were setting up their equipment we emptied the Attic. took them all of an hour to spray one end to the other. they put anywhere from 10 to 12 in of insulation all the way across my attic. they cleaned up their mess thoroughly and left nothing behind inside or outside of my home. I have referred American insulation 2 my parents. as they need to have some AC duct work done as well as insulation sprayed in. thanks to Craig for the prompt and courteous service"

Insulation FAQs, answered by experts

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.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.
