"I communicated with Ron directly and he was determined to solve our insulation problems. He had to remove drywall in our entranceway and add in insulation where there were large gaps and air was getting in. He had a worker drywall and patch up the wall. The drywall worker did an amazing job! 
Ron also fixed an ongoing issue we had in our garage ceiling that was causing our living room floor to be cold and drafty. He worked around our schedule and made multiple visits to our home to fix the issue. We are happy customers and happy to say that the problem is fixed. We were very pleased with Ron and his company and do recommend him highly.

"I contacted six companies for estimates to remove attic insulation, air seal and sanitize the attic, and blow in new insulation to R49 specs. Air-Tight's estimate was in the middle of the pack. Justin Wolfe, owner and CEO of Air-Tight LLC, gave me an estimate over the phone, answered every one of my follow up questions, and scheduled my work within the week. He stopped by at the beginning and end of the job. The crew did exactly what he said theyâ d do and were very mindful of my property. My neighbors commented on how nice they left the area. He even sealed an area under my steps and at the back of my home where Iâ d seen chipmunks enter and had an opportunity to sell more work when I asked him to check the attic above my garage but said I didnâ t need it and stayed with his original estimate. I recommend Air-Tight LLC without hesitation and am thankful I chose them."

Insulation questions, answered by experts

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.
