"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."

"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."

"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"

Insulation FAQs, answered by experts

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.

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

For a DIY solution to protect an outdoor faucet from freezing, you can craft a cover using spare rags, a durable plastic bag, and duct tape. However, be aware that this method may not be as effective as a store-bought cover. Fabric like rags or old towels can absorb water, which could freeze and cause problems. While a DIY cover can work as a temporary stopgap, a proper outdoor faucet cover is inexpensive (often $5 or less), easy to install, and readily available, making it the recommended long-term solution.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

Garden blankets and frost cloths are the best things to use to protect trees and plants from frost. They are made from polypropylene fabric, which is lightweight, breathable, and dries fast. If you can’t get garden blankets or frost cloths before the freeze, you should use lightweight blankets, sheets, or towels.
