"Ed came when he said he would and had a proposal to me the next day.  This company is busy and I see why.  Each crew that showed up was professional and hard working.  We had a little communication glitch, but it was not a big deal and they went above and beyond.  I'm happy with the work and the price and I would recommend them and use them again in the future.

"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."

"I was considering foam insulation for the last two years and got several quotes from different companies but it was always unaffordable till I came across NC foam Pros, the price was very affordable so I decided to try their service on rental home first , The process was smooth , promptly responded to my questions .Had same week appt, and the difference the foam insulation made was very noticeable, the house was old built in 1958 and barely kept heat now it feels very comfortable, so this week we gave them three more jobs and I will consider them for any future insulation job because I can Finally say I found a good deal without surprises"

"I used Vanco for attic and crawlspace insulation. They told me it would take two and a half days and they completed on time. Also, they cleaned up after they finished. I'm very pleased I employed them. I would definitely recommend them."

Insulation questions, answered by experts

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.

The cost to install a radiant barrier ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot—which can add up quickly.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.
