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

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.

DIY is possible for basic rolls or batts, but professional installation ensures even coverage and efficiency.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.
