Start with the contractor's actual experience building for older adults, not just general bathroom work. An accessible-bathroom remodel is its own skill. You want someone who has done curbless showers, reinforced walls for grab bars, comfort-height fixtures, and lever taps that arthritic hands can manage. Ask to see photos of aging-in-place jobs they've finished, and ask who did the work.
Ottawa's housing stock shapes the job. In older neighbourhoods like the Glebe, Sandy Hill, or Westboro, you're often dealing with narrow doorways, uneven subfloors, and outdated plumbing behind plaster walls, so budget mentally for surprises once the tile comes off. Condos downtown and in Kanata bring their own hurdles, since you'll likely need approval from the condo board and have to coordinate around building rules. Split-levels and bungalows in Nepean, Barrhaven, and Orleans usually give a contractor more room to reconfigure a layout properly. Winters here matter too: crews book up fast in warmer months, and material deliveries can slow when the weather turns, so plan ahead.
Insist on a written quote, a realistic timeline, and a clear warranty on both labour and fixtures before anyone starts. Confirm the contractor carries liability insurance and WSIB coverage, and that any electrical or plumbing changes are permitted and inspected. Good communication counts. You want someone who returns calls and flags problems early rather than after the invoice.
Our advice: hire a contractor who specializes in accessible and universal-design work, even if a general renovator quotes less. In our experience, the specialist gets the slope of a curbless shower, the blocking behind grab bars, and the turning space right the first time, which is exactly where cheaper jobs fail your parent. The trade-off is honest: specialists book further out and cost more, so you'll wait longer and pay a bit more for work that holds up.
