"Mike (owner) and Kyle were very knowledgeable and hard working. In two days, they modified the venting in my attic and bathroom so it would work correctly and sprayed 13" of insulation in my attic. They were efficient, friendly, and professional. They left my house completely cleaned and explained everything that they had done. It was refreshing to work with a contractor that obviously has his customer's best interests at the top of his priority list. I would highly recommend Mike, Kyle and Bill Busters for any consulting and installation on insulating products."

"This whole experience has been nothing but a pleasure with all that have come out to put a new roof and gutters on and to also install insulation in my attic. The two gentlemen (Mike and Ethan) who did the insulation were outstanding. Curteous and very very nice young men and a pleasure to talk to. They did an outstanding job and I would HIGHLY recommend this company when it comes to having any home exterior jobs done. If I could give them a 100 stars I would!!!!"

"Down to earth and tells you the truth about what you are getting. The other installers were not like Matthew Harr. I put a star by his name after I talked to him. I knew I would be calling him back. Give him a call for your next insulation project. You will not regret it! I would definitely call him again."

Insulation FAQs, answered by experts

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.

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.

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.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.
