"They arrived on time, it took about 2.5 hours, there is at least 18 inches or more of insulation, and I cannot wait to see the difference in the temperature in the house! Next weekend will be to do blown in insulation in the walls! Many thanks to owner Mike DePasquale and Energy Consultant Kevin Sweeney!"

"I our roofing consultant Steve was excellent and explaining insurance all that needed to be done is very knowledgeable about his job and we appreciate all the things that he did for us. He was very polite and courteous, and I always had a smile on his face.. all of the work was done in a timely manner and that is why I gave them a five star and we recommend this company to anyone who needs roofing work or replacement. The crew cleaned up after themselves and make sure there were no nails or old shingles on the ground before leaving."

"We scheduled them for a particular week months in advance as the project was on a tight timeline. They could not start until after the demo upstairs and had to be done before HVAC installers showed up. Everything was completed on-time and the price paid was as quoted despite having to make a few changes to the plan once the walls were opened. Fantastic company. They want to do a good job and it shows. We were concerned about residual odors from spray foam but there are none. Most importantly the house retains heat with way less fuel burned! We heat primarily with wood and used to have temps drop >20 degrees from the moment we loaded up the stove before bed until waking. Seriously, the fire would burn for hours with the house at 75 degrees after we got in bed, but when we woke, it was 53 inside the house. Now with similar outside temps we don't bother to load up the stove before bed and we wake up it is maybe 8 degrees cooler. I love a morning in the mid-60s compared to the low-50s INSIDE my house in the winter. If you are going to retrofit your house with spray foam insulation, it is a huge and messy job, so be prepared for that. There are little bits of spray foam you have to clean up later, in the driveway, yard, house. You have to live somewhere else for at least 24 hours, but we stayed away almost a week while odors decreased. We had one issue where the AirKrete leaked through the inside of the house wall in 3 location and was not noticed by the crew. We came home to see the job they did and found globs of hardened foam hanging down the walls in these locations. I called Torsten and he reported this had not happened before, most houses don't have holes in walls on the inside, and had they seen it they would have cleaned it up. He came on site and helped me clean it up and apologized, which went a long way with me."

"The customer service was outstanding. When I getting a quote from them, Justin had answered all my questions and I felt well informed when making my choice of insulation. At the day of install, the installers were on time, quick, and left my house as clean as when they got there."

Insulation FAQs, answered by experts

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more. 

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.
