"In July 2024 I hired Insulation Labs to add more insulation to our attic. They showed up on time with a truck full of insulation, and a few hours later they had put all of it inside our attic. They did a good job up there. I am very pleased with how everything turned out. One thing that distinguished Insulation Labs from some other outfits is that they did not try to up-sell us with services we didnâ t need."

"I love the insulation. My room has no insulation at all. Every time I entered the room after coming from work, it was like walking in an oven. With the insulation, my room now is cool in the afternoon. The price Pro Insulation, Inc. charged is reasonable. I just love it. It is a good investment."

"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"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!"

"Fibers Insulation was extremely professional right from the first call. I chose their service from Angie’s Lust and within minutes Geovany responded. He came out on a Saturday to provide a quote and followed up days later. Members of the company were here at the designated time and did a stellar job! I insulated my garage to add better barrier for my garage to enhance a new AC unit to offset summer heat. Geovany followed up after the installation to ensure all went well. To ensure a better look, taping will be added to keep it looking great. I will recommend them to others in my gated community as I am very pleased with the result."

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.

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.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.
