"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"Met Mike, had a nice visit on my front porch. I accepted his proposal and his men came to install the insulation. I made a pathway for his men s access, showed them the area to be done. A few hours, they were done. They cleaned up after themselves."

"They simply did a great job. I had them remove the old insulation, install new batt insulation, and add radiant barrier in my attic. Now my attic and house are a whole lot cooler. It is noticeably cooler in the house. The person who contacted me was Dustin. He was very professional and did a great job explaining things to me and laying out my options. The crew, which included Aldo, Roman, and Aaron were very professional and respectful to the care of our home and performing their job. I would definitely recommend and am willing to rehire them again for possible future projects. Thanks guys."

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"I couldn't be happier with the experience I had with this company. From start to finish, they were extremely professional, honest, courteous, and respectful of our home. They did an excellent job blowing insulation into our attic, and they made sure to keep everything clean and tidy throughout the entire process. What I especially appreciated was dealing with a family-owned business consisting of a father and his two sons. It's refreshing to see a family take such pride in their work and treat their customers with honesty and respect. Their pricing was also very reasonable, especially considering the quality of their work. It's not often you find a company that checks all the boxes: great workmanship, fair pricing, professionalism, and integrity. I would highly recommend them to anyone looking to have insulation work done. They definitely earned my five-star review!"

Insulation FAQs, answered by experts

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

The lifespan of crawl space insulation depends on how well you maintain your insulation and the type of insulation. Fiberglass will need replacing every 15 to 20 years on average if you don't have a vapor barrier in place. If you do have vapor barriers in place, then your insulation could last much longer. Spray foam insulation can last anywhere from 80 to 100 years. 

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. 

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.
