Quick answer
In Dundarave, a tankless water heater repair typically lands between $250 and $900 once the technician has identified the failed part, and the $90–$150 diagnostic visit is normally applied to that total. That range is a ballpark built from 2026 public market data for the Lower Mainland, not a quote for your specific unit — CANRO's certified gas technicians confirm the real number after they've inspected the heat exchanger, igniter and venting in person.

Dundarave sits on the hillside above the waterfront, and a good share of the tankless units CANRO services in this pocket of West Vancouver were installed to feed larger view homes or older character properties that were re-piped years ago for on-demand hot water. When one of these units stops firing, loses ignition mid-shower, or starts throwing intermittent flow faults, the repair almost always lands in the same general band no matter which brand is behind the access panel.

Where a job lands inside that range has less to do with the street it's on and more to do with what actually failed. A flow sensor or an igniter is a quick fix near the bottom of the scale. A heat exchanger fault or a control board swap pushes a bill toward the top.
Labour on any of this bills at the standard licensed gas and HVAC rate, roughly $95–$165 an hour depending on how involved the call turns out to be.
A unit on its second or third repair in a couple of years, or one where the heat exchanger itself has cracked or corroded through, usually isn't worth chasing with more parts. CANRO's technicians will show you exactly what failed and talk through repairing versus replacing before you commit to either path — the goal is a decision you understand, not a sales pitch.
For a first-time failure on a unit that's still well within its working life — an igniter, a flow sensor, a fan motor — repair is almost always the sensible call, and most of these are done in a single visit.
Most repair visits don't need a municipal permit, since nothing about the gas line or venting changes — that only becomes a factor if the fix involves relocating or resizing the vent run. CANRO technicians carry the parts most common to West Vancouver tankless installs, which keeps the majority of these calls to one trip.
Because street parking near the village and along the hillside streets can be limited, it's worth flagging any access issues when you book so the technician can plan for them ahead of time.
Safety note
If you smell gas or hear an unusual hissing sound near the unit, leave the house and call FortisBC at 1-800-663-9911 from outside before doing anything else. Tankless water heater repairs on a natural gas line must be carried out by a Technical Safety BC licensed gas fitter — CANRO holds gas licence LGA0043870.
Most sudden shutdowns trace back to an ignition fault, a blocked flow sensor, or a venting obstruction that trips the unit's built-in safety cutoff. A technician pulls the fault history off the unit's control board to narrow it down before pricing a repair.
No — CANRO applies the $90–$150 diagnostic visit toward the repair once you approve the work, so you aren't paying twice for the same trip.
A homeowner can sometimes manage a basic descaling flush with a pump kit, but if the unit is already faulting, opening it up to trace the real failure should go to a licensed gas fitter.
The North Shore's Capilano-fed supply is quite soft, so scale-driven failures show up less here than in communities on well water, though regular flushing still extends the unit's working life.
Most single-part repairs finish in an hour or two on the first visit; anything needing a special-order part means a short return trip once it arrives.
You'll get a plain breakdown of each item and its ballpark cost before anything beyond the diagnostic goes ahead, so you decide what to approve.
