I had my energy efficiency test done through Clean Nova Scotia a few years ago and was lucky the person who did the assessment was a seasoned veteran in the industry with lots of good suggestions. When I was informed I need to insulate I asked him who I should consider and he suggested Uniacke Insulators. I called them and Mike Zinck came over a few days later.
The assessment suggested adding insulation to the walls would not make a big difference. Mike felt this was worth investigating and drilled a few test holes. I was absolutely amazed by what I saw - or should I see did NOT see? There was hardly any insulation in the walls so Mike was spot on! He made more recommendations regarding insulating the house and I cannot thank him enough. My house now stays warm in the winter and cooler in the summer.
