"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"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."

"We had no problem or issue with this company. They came and did exactly what they said and promised. The service was fast too. We were able to schedule them for the same week and the work was completed after 2 days of work. According to the technician that worked at our house, it was better to use the opportunity when the attic empty from the old insulation and to replace the ducts as well. For the price that we were able to got, we decided to do that too.
so overall, we are in the stage that we will use this company in the future and we will refer them to people that we know and might need the same kind of work to be done.

"These guys saved us during the recent heatwave. I looked for days for someone to come help us service our airconditioner, which was working....except for the cold air part. These guys were so easy to get in touch with and they put us on the schedule for the next day. They took a look and the fix was really easy. They serviced the AC, made some recommendations for future upgrades (but made sure to let us know they weren't emergencies) and left us with a house full of cold air. It was one of the easiest home services we've had in our new house. HIGHLY RECOMMEND."

"GC Heating and Cooling put in a 3 zone furnace and AC system for our 3100 sq ft house in Manhattan Beach back in 2018. We recently had an issue due to the unprecedented heat wave and Gustavo and Jordan fixed the issue under short notice. You can always expect quality work and great service from them."

"Mario is an amazing technician! He came to my home on time, was professional, courteous, and knowledgeable. The visit was only for a maintenance of my heating and AC unit, but Mario noticed some concerns with my insulation. He took an immense amount of time to explain to me the entire process of how they will clean out and replace the insulation. I was extremely satisfied with the service provided. Mario really embodies the core values of Home Comfort and went out of his way to make sure that I was comfortable with the plans being made and that I was happy. He also worked out an amazing deal for me on the insulation project. He is the best technician and I left feeling that I am a valued member of the Home Comfort family. Thank you, Mario!!!"

Insulation questions, answered by experts

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

If the outside temperature drops below 20 degrees Fahrenheit, it will take around six hours for your pipes to freeze—and they might even burst. That’s why keeping your mobile home’s temperature around 50 to 60 degrees Fahrenheit is necessary, even if you’re leaving it vacant for the winter. In addition, having ample skirting around the mobile home's underbelly will help keep pipes insulated during the winter.
