"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.

"WOW! Mitch is GREAT! We had the slab under the Carolina Room collapse. We were devastated by what would be needed to repair or what caused it. Mitch came in, explained the process and went to work. Clean, friendly, informative, proud of his company, confident. All traits you want when you hire a contractor. Ba-da-bing, the job was done. He pumped foam in to lift, support and stabilize the slab. It was amazing to watch. Mitch said even after doing this work for so long, he still gets a wow out of it. I like that! Someone who truly enjoys his work. Price was expected and we considered most fair."

"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."

"Our builder had never used spray foam, so once we decided to go spray foam, we got a great education from Rich Brown of Prime Energy group. He was wonderful to work with, and helped guide us on some very important issues including HVAC sizing. His company had all their paperwork ready for Orange County NC inspectors, and he was very flexible given all the delays we experienced before we were ready. When our spray day finally was approaching (4 months after the initial consultation), Rich came out again to go through the job again with us, answer any last minute questions, and make sure he did not see any concerns for going forward. Once we were ready, the company sent two crews. Rich went through the job with them and they finished it in one day! The crews even did a good job of keeping the mess to a minimum, despite the fact the trimmed foam bits are very much like styrofoam to manage. The inspection went off without a blink, and the job looks great! I really would recommend them as top notch, and priced fairly for the level of job they did for us. My only remark for those considering spray foam: make sure all outlets, vent pipes or air inlets are in their final place and fastened down before spray. You cannot easily reposition or push them into place afterword, and who wants to damage their new insulation? Thankfully, we thought of that for the outside vents because those would have been a nightmare to fix. On inside, we had two outlets that were screwed only from one side rather than nailed and the dryer vent 'hutch' that was not fastened that were pushed out by the foam which are going to be difficult to fix. My husband will also have to pull the sides of our shower pan liner and cut some foam back before that area is tiled since the flexible liner pushed in, but that should be simple. We used open cell foam and are very happy with the results, and there are no weird odors or fumes after a day's curing. Call Rich, he knowns his stuff."

Insulation questions, answered by experts

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

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.
