"Very Professional job. Adding insulation to the walls of our home has dropped our energy bills. Would absolutely tell somebody else to have this done especially if you have an older home."

"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."

"These guys, from GW the sales man to Bradley and Adam the installers were first class. I would recommend them to anyone, both the salesman and service techs were here at the time they said , not one min. late and their care for their work is second to none. Having been in the building business for years, I can say these guys are growing a co. on quality service bar none. Also the care they have for your house is great, from start to finish, couldn't tell anyone ever set foot in my house. Also the price was hard to beat.

"My family and I have been living in an RV for over a year now, due to hurricane Florence. It has been a nightmare dealing with shady, lazy and difficult tradesmen but doing business with Mitch has been the easiest thing in this whole process. I called him on a Friday to insulate my entire home and he was completely done by the following Tuesday, before lunch time. He s extremely friendly and an excellent communicator. He kept me in the loop the entire time and showed up when he said he was going to. He does quick work but he is very proficient and he actually cleaned up after himself, which seems to be completely unheard of. We called around to multiple businesses for spray insulation and Mitch is by far the BEST price you will find out there. He even gave me a really good discount because I think he s just a nice guy. I highly recommend Mitch. He will make your life easier in regards to upgrading your home."

"Mike and Enrique showed up early and worked non-stop insulating my attic and my basement ceiling. I would recommend Farrell Holdings to anyone seeking to have insulation work done. Mike Morin explained exactly what he would be doing, before blowing the insulation in the attic he filled what he considered vulnerable or weak areas with a sealant. He did a pressure test before and after the application of the insulation to determine how well we would benefit from the added insulation. If you're looking for professionals this is the place to call."

"I would highly recommend Prime Energy!! Rich (Sales Mgr.) was exceptional from the first contact to the last experience. The crews were top notch in all they did and finished a large project in just 3 days (removal & installation). Very pleased with the final results and the temp difference in our attic has gone from 150 down to upper 70 s. I would definitely recommend this type of insulation and Prime Energy to do it. Very Satisfied Customer, Jason C."

Insulation questions, answered by experts

A radiant barrier is a form of insulation topped with a reflective material designed to keep homes cool during hotter months. It is generally considered worth the investment if you live in a hot, sunny climate, as the cost can be recouped over time through lower energy bills. Installation costs typically range from $0.10 to $1 per square foot. After installation, homeowners in warm climates may save between $7 and $15 per month, potentially reducing their electric bill by 5% to 10%. The exact savings will vary depending on your location and the type of barrier chosen.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.
