Start by measuring the doors your parent uses every day: the bedroom, the bathroom, the main entry and the route to the kitchen. Then measure their walker or wheelchair at its widest point, including hands on the wheels. If a door is just a little too narrow, offset hinges may solve it. These swing the door fully clear of the frame and add useful width for a modest cost.
If you need to widen doorways for wheelchair use, the work becomes carpentry. In Burlington's older homes, plaster walls, older wiring and heating ducts can run through the wall beside the door, which adds steps. Some walls are load-bearing, which needs a proper header. Split-levels in Brant Hills and Headon Forest sometimes have short hallways where turning into a door matters as much as its width, so think about the approach too.
Prioritize a contractor who has done accessibility work and asks about your parent's mobility aid, not just the door size. Make sure they're insured, check for wiring and ducts before cutting, and give you a written quote that includes patching, painting and trim. Ask about lever handles and lower thresholds while they're there, since small changes add up.
Our advice is to try offset hinges first on any door that's close, then widen only the doors that still don't work. Widening every doorway feels thorough, but the trade-off is more cost and disruption than many families need. Burlington families often compare contractors from Hamilton, Oakville and Waterdown too, listed nearby. Keep receipts, since this work may qualify for the federal Home Accessibility Tax Credit.
