Robert Carroll, the owner, has 30 years of experience in the insulation and ventilation business. Attic Air has been in business since 1996 and specializes in insulating and ventilating residential homes. Attic-Air will come out free of charge to evaluate your home. Robert Carroll will be at every site to ensure a job well done and that you will be a satisfied customer. (No subcontractors used)

"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."

Insulation questions, answered by experts

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

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.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.
