Horizon in Markham

I was helping a client renovate their house and needed to open three bathroom exhaust vents on the roof. Then I found Addison. This was not the first time we had cooperated. With his suggestion, we chose metal vents because there were more trees around the house. Many animals often run onto the roof. It has been completed today. It is raining heavily outside and there is no leakage at all. Thank you.
