Start with the entrance you actually use most. Many Hamilton homes have their real living space up a short flight of steps, and older houses downtown or in the North End often sit close to the sidewalk with awkward stoops. A good installer will measure the rise and design a ramp with a safe, gentle slope (about one foot of ramp for every inch of rise), plus level landings where the door and any turns are. That slope math matters more than looks. A ramp that's too steep is harder and riskier to use in a wheelchair or with a walker.
Prioritize installers who work with seniors and understand accessibility, not just general handymen. Ask whether they're licensed and insured, and whether the ramp meets Ontario Building Code where a permit applies. In our experience, the details that make a Hamilton ramp last are a proper non-slip surface, sturdy handrails on both sides, and a design that sheds snow and ice instead of trapping it. Winter here is long, and salt and freeze-thaw are hard on cheap materials. Also ask about warranty and how quickly they respond if a board loosens or a handrail wobbles.
Our recommendation: for most families, choose a modular aluminum ramp over a custom wood build. Modular ramps go in fast, need almost no maintenance through Hamilton winters, and can be removed and resold if your parent's needs change or the home is sold. Custom wood can look more built-in and sometimes costs less up front, but it needs sealing and repairs over time and holds less value later. The trade-off with modular is honest: it can look more utilitarian, and a permanent wood ramp may blend better with a heritage home's front porch. If appearance near the street matters to you, weigh that against the years of upkeep you're signing up for.
