"We were so happy with our experience with Randy from Paragon Services, we have had him out 2 times in the last month to address both the attic and the crawl space of our new home. After Randy and his team replaced our fiberglass insulation in the crawl space with spray foam, it raised the average air temperature on our first floor by over 15 degrees! I has made a HUGE difference right away and I can’t wait to see the $$ we save on our heating/air conditioning. Paragon Services is fast to respond to messages and phone calls. Randy was able to come out for a quote within a few days we were on the schedule within a week or two. On installation day, the crew was on time and professional. I was blown away by Randy’s knowledge and honesty. I never felt rushed during our conversations or pushed to commit to a purchase. He took his time to investigate the issues, develop an appropriate plan of action, and prepare a thorough quote. He went over everything with me to make sure I understood what he was proposing and why. I learned so much just in our few conversations. I also loved that he not only addressed the issue I called him out for, but made sure any related issues were addressed as well. The prices are very reasonable and their customer service is excellent! I definitely recommend Randy and Paragon Services!"

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."

Spray foam insulation services FAQs

Yes, you should remove old insulation if it's damaged, contaminated, or deteriorated. Signs like water damage, rodent droppings, mold, or gaps mean removal is essential to maintain energy efficiency and a safe living environment. If the insulation is intact and functioning well, removal isn't necessary. However, compromised insulation can increase energy costs and pose health risks.

Attic insulation lasts 80 to 100 years; however, its performance starts to decline after 15 years. Insulation loses effectiveness as materials like fiberglass become dirty, wet, or affected by mold and other contaminants. Regular evaluation is critical because reduced insulation performance leads to higher energy loss. A professional inspection confirms when replacement is necessary, ensuring that your home maintains peak energy efficiency and comfort.

Excess attic insulation does not enhance energy efficiency beyond an optimal threshold. When insulation surpasses the necessary level for your region’s climate, additional material does not improve heat retention and may cause moisture buildup. Maintaining the correct balance is essential because over-insulation can lead to unintended issues without lowering energy costs. A professional assessment ensures that the amount of insulation is ideal for performance and efficiency, and helps avoid unnecessary expenses.

R-value is the measure of a material’s ability to resist heat transfer and directly determines insulation performance. A higher R-value means the material retains heat efficiently during winter and minimizes energy loss in warmer months. Selecting insulation with the appropriate R-value for your specific location is essential because environmental conditions and installation areas significantly influence energy efficiency. Over time, external factors like moisture may degrade the R-value, which underscores the importance of periodic evaluation.

Insulation damage occurs in several forms, including mold growth, pest infestations, water intrusion, and electrical harm. Damaged insulation compromises heat retention and significantly increases energy expenses while posing serious health risks. Immediate removal and replacement of compromised insulation are imperative to restore optimal performance and ensure the safety of your home. Regular inspections will identify these issues early, allowing for swift corrective action that maintains efficiency and protects occupants.
