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."

"This is the most negligent contractor I've dealt with in my life. They suggested to not be home for our attic insulation since we have a newborn at home which I appreciated. They seemed careful and thoughtful in the sales process which is why I ended up picking them for our project. However, when it came time for the job they were reckless with security and safety. Before the job I sent multiple notes via text and email, and had a phone call asking them to contact me at the end of each day so I could set the alarm and lock the doors remotely. Day one they didn't do this. I sent another ask to please be mindful of this so I could keep our home secure. Day 2 they did not do this again, and ended up leaving our front door wide open which triggered a burglar alarm at 2am requiring us to deal with the security company and police throughout the night. Afterwards it took days for anyone to reply. They lacked empathy or ownership for how negligent their team was. I would not recommend working with these people. Mistakes happen, but the response to these mistakes was almost as bad as their dangerous actions themselves."

Insulation questions, answered by experts

While freezing pipes are less of a concern in warmer climates, pipe insulation can still be beneficial because it helps prevent condensation on cold water pipes, reducing the risk of moisture-related issues like mold growth. It also helps maintain water temperature, reducing the energy needed to heat and cool the water, which can ultimately lower your utility bills.

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.

Periodic checks for moisture or pest issues ensure consistent performance.

You can buy pipe insulation materials in your local hardware store or in major home improvement stores. You can also shop for insulation online, where you may be able to more easily buy in bulk. When shopping, make sure you know your pipe's dimensions so you can buy the correct size of pipe insulation materials for your pipes.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.
