"We had insulation installed a week earlier by Koala. During the insulation, Jasper (insulator) suggested another area that we might consider installing blown-in insulation. We agreed and the second job was performed on Friday, the 24th. Jasper and Richard were on time, the insulation project was well done and they left the area very clean. Would use them again."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

These vents help your attic circulate air. With attics reaching over 120 degrees in the summer these are very important. They prevent mold and increase the lifetime of your insulation. Most other contractors miss installing these.
Look at the difference! Our foam is fire-rated which allows us to air seal around penetrations that contractors never could before.
Most homes have penetrations all over there attic. Imagine trying to blow up a balloon with a bunch of holes. It will never fill up. Now imagine trying to blow up your house with air conditioning and heating with a bunch of holes in the attic. It will never fill up.
Recessed can lights are notorious for leaking air. Recessed can light covers help with air-sealing your living space and prevent fires.

"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"I hired Atlas Home Energy Solutions to remove old insulation and replace it with the foam technique. However, I ran into numerous unexpected problems due to a slow leak from old pipes. It took awhile to sort out. Atlas Home Energy Solutions gave me lots of expert advice. They were willing to come out and review the situation. They were also willing to reschedule and wait until another contractor dealt with the water issue and its ensuing problems. They helped me make some difficult decisions before they could insulate the crawl space. When it was ready for them to come and insulate the area they bumped their schedule forward to get it done. This company did sterling work. Their expertise and professionalism were outstanding. They really know what they are doing and guided me through a more protracted process than originally envisioned. I would highly recommend them to anyone."

"Brian came out to perform an energy audit on my home. He arrived on time, was respectful of my home and showed me where my insulation was missing with his infrared camera! His report came two days later as promised with a reasonable quote."

"Highly recommend for any insulation project. Dan Hope is extremely knowledgeable concerning home insulation and was pleasant to work with. I have cantilevered second story floors and poor insulation was causing a duct vent to develop condensation with this 2024 heat wave which caused moisture to drip down inside of my first floor ceiling. Dan fixed the insulation issue and then some. He inspected the house and advised improving the insulation around a room that sits above our garage that was notoriously difficult to temperature control. I would hire him again for another project in a heartbeat."

Insulation questions, answered by experts

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

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.

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. 

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.
