Door repair in North York usually starts with a size problem. The post-war bungalows and side-splits around Bathurst Manor, Downsview and Willowdale were framed with openings narrower than anything a builder uses today, so a replacement rarely drops straight in.
I am Sercan, and I do this work myself. Sometimes the answer is a new slab cut and bored to suit the old frame. Sometimes the frame itself is done, and a pre-hung unit with fresh trim is the honest call. I look at the opening, tell you which it is, and agree a price before I start.
