Earlier this year we completed a custom, passive house, whole house renovation in Toronto. Scotty was introduced to us by our contractor. The house required significant Roxul insulation in all walls of this 4 level (including basement) renovation. It also required the installation of a specialized vapour barrier that had to be sealed with special tape to ensure a complete air tight envelop.
Our goal was to reach an air tightness level that was below 1.0 ACH50 (air exchanges per hour at 50 pascals of pressure). We tested the house after Scotty's work was complete and we achieved 0.87 ACH50, exceeding our goal!
Needless to say, we are very happy with the work Scotty did. There were many tricky areas that needed to be sealed in an air tight manner and Scotty spent significant time making sure it was done properly without cutting corners. He is also an absolute pleasure to deal with one of they very few trades we met through our two year project who truly, truly takes pride in his work.
I highly recommend him.
(Scotty, thank you for all your hard work! We are now in the house and enjoying the comfort resulting from all your hard work - John)
