"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."

"Wishing there were more stars to give to Newtonian's Renovation than the 5 offered! For their estimate for more attic insulation at our house they arrived on time and went into the attic and took photos to show my husband what we currently had and what their plan was to bring us up to the R49 level. My husband discussed with them his concerns about the baffles and the HVAC unit in the attic. This company listened and discussed w hubby what their plans were to fix any issues first so the extra insulation will do the job it is for which is to make the attic more energy efficient. When the workers came to do the job they cleaned up as they went along and let my husband know their progress and again took photos to show him what the end result looks like now. This is an upstanding company and they offer more services than just attic insulation! Happy we found them through Angi.com!!"

"Won the job with the best bid and gave me the best impression during consult. Work involved removing all insulation in crawl space, hydrogen peroxide blasting the subfloors and crawl space, and putting in new insulation and vapor barrier. While the price was high, it seemed to meet / beat market pricing. Company was nice to talk with and told me exactly what they were going to do, when they were going to do it....and did it. Good communication. Too many contractors are just awful in this area, but not this one. Would recommend (but hopefully not have to use again!)"

Insulation questions, answered by experts

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.
