"So happy I went with USA Insulation. After learning about foam insulation, I knew it was the right option for my house. They insulated my walls and attic in a day and a half, and I could feel the difference right away."

"We recently worked with Evergreen Foam & Insulation on a new construction project where they applied spray foam insulation to the walls and roof deck. Their team was professional, efficient, and maintained clear communication throughout the process. The quality of their work met our expectations, and they completed the job on schedule without any issues. The attention to detail during application was excellent, and the site was left clean and ready for the next phase of construction. We’re pleased with the results and look forward to working with Evergreen Foam & Insulation on future projects."

"Charles was awesome all around!! Came out for an inspection, advised me of issues and the route I should take. We followed through and couldn’t be happier with the results, and how easy the process was. We got a full encapsulation with a dehumidifier and the difference in the air is amazing. Highly recommend if you are thinking about getting your crawlspace encapsulated!"

Insulation questions, answered by experts

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

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 can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency. 

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.
