Customer Reviews & Testimonials of Our Services


5/5 based on 29 ratings and reviews for Service.


  • "I recently hired OJ Insulation to insulate the walls of my 1950s vintage home. There was virtually no insulation in most of the walls of my house. The west facing walls would be hot to the touch in the summer. Now with the insulation, those same walls feel cool. This is the second time I used OJ for insulation. A few years ago, I had them install insulation in my attic space. I would highly recommend them for your insulation needs. The prices are very competitive, and they will generate an invoice that can be submitted for a rebate from the Gas Company. The salesman, Mark Teagle, and the crew that did the work, were all very easy to work with, and provided helpful information."
