"I was really impressed with the quality and professionalism we received from Correct Energy. They gave us a fair price and performed the work almost immediately after the consultation. The end result was unbelievable too. The second floor is usually so hot but after the spray foam even without AC the temperature change was drastic, and it's far less noisy as well. I was also impressed with how well they taped off the walls, floors, and electrical to cut down on the mess afterwards. I didn't have to do any cleanup at all. Would highly recommend this company and we will be using their services in the future for subsequent projects."

"I had an Absolutely Fantastic Experience!! My husband & I were so lucky to have gotten Jason Scharf to come out to our home, he was very insightful, helpful, courteous and very professional. Jason explained step-by-step what he was doing along the way & what would work best within our home with 4 different price ranges that would work for us. Jason was very informative. He mentioned and advised me on some items that would require attention on a monthly basis which I was grateful for. Upon completion, he reviewed the bill and explained any questions that I had. I was very pleased. Overall, Jason’s work was outstanding. I would recommend Jason from Astar to anyone I know that is in need of a central air system in their home. He was one of the kindest, funny and coolest Design Specialists by far. Thanks again Jason you're the Best! We can't wait for everything to be completed."

"Justin is a true professional and his crew go above and beyond to complete the job. While spray foam insulation is not cheap I feel that the job I received will pay dividends years to come. Justin is deeply committed to his community and I work beside him every year as volunteers to build our ice palace before winter carnival. His ethics are shown thru this work and it translate into his business. Thank you. dave"

"We have had them for about three years and we have also been very satisfied. They have been responsive to us. Once we had a snake in the basement and I did not want to deal with it, I called them. They could not help me, but they referred me to somebody else who did."

"R-Factor Insulation Company does very good work. They insulated my crawl space and did a wonderful job. The owner Mr. Knapp was very professional and came out and gave a free estimate on the work. The job estimate was right on the price with no cost over runs at the completion of the
job. I had other estimates that were much higher on the same work to be done."

Insulation FAQs, answered by experts

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.
