"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."

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."

"Home Repair Fraud. Theft by deception. We got a new floor and the installer said his brother was the field estimator and was authorized to remove the "Kitchen Cabinets"? We never wanted cabinets from a flooring company, But they targeted the owner because she is 91 years old and took them. Months later we got them back from the ex-con and hoodlum they sent to rob the owner totally destroyed and had to pay another $1300 to get them back. We feared for our safety because they wanted to know if the house was for sale and what types of cars we were driving. They prey upon the elderly. Do not use this company unless you have a criminal attorney on retainer. Stay away from DeSitter at all costs."

Yes, insulating an unfinished basement delivers meaningful benefits even if you don't plan to finish the space. Proper insulation reduces heat transfer through basement walls, which can account for up to 30% of a home's total energy loss.
This improvement enhances comfort throughout your home while potentially reducing energy costs. Insulation also helps manage moisture levels, protecting your home's structure and improving indoor air quality.
Rigid foam board and spray foam insulation provide superior moisture resistance for basement applications. These materials create effective vapor barriers while delivering high R-values per inch of thickness. Rigid foam boards resist water absorption and can withstand occasional dampness, while spray foam creates an airtight seal that blocks humidity infiltration.
For basements in humid climates or with moisture concerns, these options outperform fiberglass or wool alternatives.
Insulating basement walls provides the greatest benefit by reducing heat transfer through your foundation. This approach helps maintain consistent temperatures throughout your home and keeps floors above the basement warmer during cold weather.
Ceiling insulation might be appropriate if you specifically want to isolate the basement from living spaces above. In most cases, addressing the rim joists and exterior walls delivers the best performance for energy efficiency and moisture management.
Many building codes require vapor barriers when insulating below-grade spaces like basements. These barriers help control moisture migration through foundation walls and floors. Certain insulation types, including rigid foam and spray foam, provide inherent vapor barrier properties. When using fiberglass or wool insulation, a separate vapor barrier becomes necessary. Always check local building codes for specific requirements in your area.
Signs that basement insulation needs replacement include persistent cold spots, unexplained increases in energy bills, visible moisture damage, musty odors, or mold growth. Physical deterioration, such as compression, sagging, or discoloration, also indicates potential problems.
In older homes with outdated insulation materials, upgrading to modern options with higher R-values can significantly improve performance. When in doubt, professional inspection can help determine whether repair or replacement represents the best approach.
