"DANA Insulation had my attic insulated with blown-in cellulose. Prior to the insulating my attic, my bedroom upstairs felt like a sauna and I always had a miserable time sleeping. I noticed a huge difference and I can now sleep comfortably in the hot summer nights. The crew did a superb job and was very kind to answer my all the curious questions."

"Another contractor had moved things around so much, that it botched my previously scheduled insulation appointment with another insulation company. In a panic, I reached out and was properly given an estimate work completed within days. They arrived earlier than first estimated and that was more than welcome. Handled with care and our property was protected and insulated with care."

"From Tom Mackey the GM, to Judi in the office, to Al the job site foreman, this was one great company to have done work in my home. I have had a lot of different crews out over the years and Dana Insulation is at the top. Honest and professional all the way through, and the outstanding work was completed sooner than I expected. Highly recommend this company for insulation needs."

Insulation questions, answered by experts

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

DIY insulation installation is feasible, particularly for basic rolls or batts, if you have the right protective gear and knowledge. However, hiring a professional ensures even, full coverage for maximum efficiency.

Reduces energy costs, improves comfort, and prevents ice dams in winter.

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.
