"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"The sales rep, Bryan, went above and beyond to answer all my zillion questions and concerns. He was responsive, knowledgeable and shared his expertise in not only insulation, but all in LED canned lights and dimmers. He was amazing and I would only ask for him again. I plan to refer others to him also in the near future. The installers were good too, letting me climb the ladder and look at the work, cleaning out the old insulation and advising me they found no termites or rodent droppings. I wish they would have vacuumed the bedroom where they brought in a lot of dirt on the carpet, and also used the shop vac in the garage afterwards, as I had to clean up afterwards, which took me an extra hour. However, overall, I was pleased."

"We had a problem where rats used to get in the attic via the air spaces. This big problem caused an infestation that required us to solve this problem and to replace the insulation.
Adam from Attic master,  was very nice to us and understood the problem very well. He sent to our house one his main guys to check and see how he can help us solving this problem. As part of his great service, he was also able to close all the openings on top of the new insulation. 
I'm very happy that 1 company could solve this problem once and for all.

"Tony and Green Apple were awesome. He gave a quote and stuck with it, even when the job turned out to be more extensive than he anticipated, showed up 15 minutes early (after giving me a courtesy phone call to let me know he was on his way), and worked very hard for three hours to clear at least 30 years of dust and debris out of the duct work. He had a sense of humor, respected the property, left the house clean and ducts spotless. Don’t hesitate to use Green Apple!"

Insulation questions, answered by experts

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

No, you shouldn’t wrap a towel, old T-shirt, or other porous fabric around your faucets. These materials absorb water, which can make your faucet more likely to freeze. Instead, you want to use waterproof, insulative covers that can seal tightly around the spigots for the best protection against frozen outdoor faucets and pipes.

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.

When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit. 

Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.
