"The guys from Atlas Insulation were great from the beginning. From our first meeting where they explained the benefits of foam insulation, and broke down the plan of action and how long it would take. Very professional crew was there on the agreed days and did an outstanding job. I m very excited about the savings this will bring!! Highly recommend this company!"

"I had an amazing experience with this spray foam insulation company. From the first phone call, they were upfront, honest, and very knowledgeable. The crew showed up exactly when they said they would and walked me through the whole process before starting. They insulated my attic and part of my garage, and the difference was noticeable the same day ? the rooms stay cooler, and the AC doesn?t run nearly as much"

"Hired A Kool to replace my AC ducts. I received 3 quotes from different companies Company 1 - Good price but told me he couldn?t work from the attic due to lack of space so he suggested I cut holes in the ceiling so he could work from inside Company 2 - Quote 21K ? A Kool - Price was right and I did not have to cut any holes in the ceiling as they did all work from the attic. Crew was very professional, and very thorough in their work. Salesman Promised the job would be done in a day and job was done in a day. Crew showed up at 7am and didn?t leave until the job was done (8:00 pm) Will Hire them to blow insulation in the attic as they found that the attic was not properly insulated. Excellent experience."

"Attic Fanatics did an outstanding job from start to finish! The team was professional, punctual, and explained every step of the process clearly. They removed the old insulation, sanitized, sealed air leaks, and then installed new insulation — everything was done with attention to detail and care for our home. What impressed me most was how clean they left the job site and how much cooler and more comfortable our home feels now. They even shared before-and-after photos so we could see the difference in our attic. It’s rare to find a contractor that goes above and beyond like this. I would highly recommend Attic Fanatics to anyone looking for attic insulation or ductwork — you won’t be disappointed!"

"Aldo and his Team at A Best Insulation were very responsive and did a great job. They were especially helpful in terms of protecting our equipment & furniture and working around our schedules. They cleaned everything up when the job was complete and were very concerned about our safety, during and after the install. We have already noticed a dramatic difference in not having to keep our Air Conditioning set as low as we used to and less humidity in the house has made us much more comfortable! I highly recommend the Spray Foam Insulation done by A Best!"

"They guys were on time, did the work very quickly and completely, and explained what they were doing along the way. I was able to observe, ask questions, and learn about how the insulation was blown in and what R-30 vs R-38 means."

Insulation questions, answered by experts

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.

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.

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.
