"Wayne and â My Insulation Guyâ did a super job. Wayne and I had several discussions by phone and set up an appointment to install the insulation. This is a family business. Waynesâ s son, Wayne Jr and Wayneâ s brother, Lawrence, introduced themselves when they arrived and worked flawlessly to insulate my attic by adding cellulose insulation. Was on time, on budget and just most importantly - 100% clean up. I would highly recommend Wayne and â My Insulation Guyâ for your insulation needs. You wonâ t be disappointed. And - you will be supporting a small local business with personalized service. Thanks Wayne, Wayne Jr and Lawrence for taking care of my insulation needs! Great Job!!"

"Koala replied to me quickly. I had 3 quotes, Koala provided the insulation I needed at a good price, but beyond that, the customer service from the quote to the work was great. It was seemless and all done with kindness, willing to take time to explain and answer questions. Prompt, in fact I made my decision on a Friday with a Monday completion. THANK YOU"

"So far we only had the energy survey and report (sales pitch). The technician and sales rep were courteous and provided answers to our questions. Neither were pushy. We are doing comparatives on the cost of adding insulation to the attic and sealing leaking vent, ducts and returns. We told them we were not interested in Solar and they did not force the issue. They did suggest we do the outlets and door molding ourselves."
