Drywall repair in North York usually starts on a ceiling. The bungalows and side-splits around Bathurst Manor, Willowdale and Don Mills went up in the 1950s and 1960s, when board was nailed rather than screwed, and those nails work loose over the decades.
I am Sercan and I handle each job on my own. I pull the loose fasteners, screw the board back to the joist, then fill, sand and feather the patch out far enough that it disappears under a roller. If the ceiling is stippled, I match the texture before you repaint.
