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."

"Marcos was friendly and fast, and flexible in scheduling. He and his crew did a great job for us in removing asbestos tiles from our basement flooring so we could have interior drain tiling installed. In the process, they also discovered some mold, which they were able to deal with at the same time. He came with a large crew, so they finished a large job very quickly. The space was well cleaned afterwards, and we received the necessary clearances. Highly recommend."

Insulation questions, answered by experts

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.

One of the biggest disadvantages of glass garage doors is that they are not the best at insulating your garage. In the summer, heat can enter through the glass, while in the winter, heat can escape through the glass, increasing your electricity and gas bills as you crank up your HVAC unit. You can help mitigate the poorer insulation by investing in insulated glass and insulating your garage.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.
