Door repair and installation in Ajax depends on which side of Taunton Road you live on. In Pickering Village and south Ajax the doors are older and solid, hung in frames that have moved. North of Taunton the subdivisions are recent, with lighter hollow-core doors and bifold laundry closets.
I am Sercan, and I do the work myself. Older doors usually want planing, shimming and a set of new hinges. Newer ones usually want hardware or a straight swap. I look at yours, quote for free, and agree the price before I start.
