Swapping out a failing gas hot water tank in Glenayre is one of the more predictable jobs on this list, but venting type changes the number more than most homeowners expect.

Quick answer
Replacing a gas hot water tank in Glenayre typically runs $1,800 to $3,200 for a standard atmospheric-vent tank, or $2,500 to $4,500 if the job needs a power-vent model or venting changes. That's a ballpark based on 2026 public market data, not a fixed quote — CANRO's certified gas technicians confirm the real price after seeing the existing tank, venting, and access.

A like-for-like swap — same size tank, same venting, same location — is the lowest-cost version of this job because the flue, gas line, and water connections are already in place and code-compliant. The price climbs when the old tank's venting no longer meets current code, when the mechanical room doesn't have a suitable chimney or vent run, or when a homeowner upgrades to a power-vent model that routes exhaust out a side wall instead of up through the roof. In a number of Glenayre's older split-levels, the original tank was vented into a shared chimney that also served a furnace, and if that furnace has since been replaced with a different venting type, the tank's vent path sometimes has to change too.
| Scope | Ballpark (CAD) |
|---|---|
| Standard atmospheric-vent tank, like-for-like swap | $1,800–$3,200 |
| Power-vent tank or venting changes required | $2,500–$4,500 |
| Municipal permit (District of North Vancouver) | $75–$200 |
A common call involves a tank in a below-grade utility room that's started weeping rust-tinged water at the base — a clear sign the tank itself has failed rather than a fixable component. In an older Glenayre split-level, the existing vent often ties into a shared chimney that also historically served a furnace, and if that furnace has since been swapped for a different venting type, the technician has to confirm the tank's chimney path is still adequate on its own before reusing it.
Access down a narrow basement stair is routine but does add some handling time compared to a garage-level install. Most of these calls are straightforward same-visit jobs once the venting question is settled, with the District of North Vancouver permit filed as part of the scope.
Most gas tank water heaters last somewhere in the 8-to-12-year range before internal corrosion or a failed component makes replacement the sensible call, though the soft North Shore reservoir water does mean less scale buildup than a hard-water region — the anode rod and tank liner are usually the limiting factor here rather than mineral scale. A slow leak at the base of the tank is the clearest sign it's past the point of repair; if you see rust-coloured water pooling under the tank, that's a replacement situation, not a repair situation, since the tank itself has failed.
Safety note
If you ever smell gas or suspect a flue or venting problem near a boiler or water heater, leave the house and call FortisBC at 1-800-663-9911 from outside before doing anything else. Never troubleshoot a suspected gas leak yourself.
A straightforward like-for-like swap is often done in a few hours; a job requiring venting changes or a power-vent upgrade can take most of a day.
Yes, the District of North Vancouver requires a permit for gas water heater replacement, and a licensed contractor handles that as part of the job.
It depends on household size and fixture count — a technician sizes it based on your actual usage rather than a one-size-fits-all rule.
Sometimes, if it still meets current code and matches the new tank's venting requirements — the technician checks this before quoting.
It's useful when there's no good chimney path available, since it vents out a side wall instead, but it isn't necessary if your existing vertical venting is sound.
Visible rust-coloured water or a leak at the base of the tank means the tank itself has failed and needs replacing, not repairing.
