"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."

"The quality and professionalism demonstrated by Rich and his crew was exemplary. I was offered a modest but helpful military discount and it helped overall because i had both my attic and crawlspace insulated. The thermostat has not been touched since the install and the house maintains a cool 74 degrees easily. My energy bill has already gone down."

Insulation questions, answered by experts

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.
