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."

"It went very well for large items such as windows, flooring, paint, guthers and screen doors. The finishing details could be better. Like puting back on curtains rods.

Insulation questions, answered by experts

For a truly DIY solution to protect your outdoor faucets from freezing, you can craft your own faucet sock out of spare rags, plastic shopping bags, and duct tape—but this method might not be as effective (or attractive) as store-bought. If you choose to DIY your own outdoor faucet cover, be aware that rags, old towels, and other fabric you might use to wrap the faucet can absorb water like a sponge and could cause problems if it freezes.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Reduces energy costs, improves comfort, and prevents ice dams in winter.

Whether or not you need to insulate exposed ductwork depends on state and local building codes. There is no national requirement for duct insulation. Even if your local codes don't require it, duct insulation can be useful to increase the efficiency of old, thin, or flexible duct materials. Ducts should also be insulated in basements and ceilings to avoid condensation.

Even though spray foam insulation typically comes at a higher price point than other insulation types, the benefits make up for the investment. Some benefits of spray foam insulation include:

  • Improved air quality, as this type of insulation helps minimize indoor allergens

  • Easy installation 

  • Lifespan of 80 to 100 years.

  • Added home strength, protecting it from humidity and wind.

  • Additional soundproofing

  • Energy bill savings
