Metrotown-area homes range from original post-war houses to recently renovated properties, and each brings a different water heater replacement to plan for.

Quick answer
Replacing a gas water heater in a Metrotown-area home usually becomes the right call once the tank is leaking, is roughly ten to fifteen years old with visible corrosion, or can no longer keep up with the household's actual hot water demand. The main planning question is whether the existing venting and gas line can be reused as-is or need updating to match current code, which a licensed technician determines before quoting a replacement.

Older houses in the blocks around Metrotown often still have their water heater in a small basement utility area, sometimes shared with the furnace or boiler in a single mechanical room, and those units have frequently already been replaced once or twice since the home was built. In more recently renovated properties, a water heater might be tucked into a smaller dedicated closet built during a basement finishing project, which can constrain what size and venting type will fit on the next replacement.
Because a lot of homes in this area have had a basement suite added at some point, hot water demand can be higher than the original tank was sized for, and a replacement is sometimes driven less by failure and more by the tank simply not keeping up anymore.
A leak at the base of the tank means replacement, no way around it. Short of that, rusty water at the tap, a rumbling noise from sediment, or a pilot that won't hold are all worth a service call to determine whether a repair is reasonable or whether the unit's age makes replacement the smarter spend. We're upfront when a repair is likely to be a short-term fix on an old unit rather than recommending it just to avoid a bigger conversation.
Tank sizing comes down to how many bathrooms draw hot water and how the household actually uses it, not just square footage. If a basement suite shares the same water heater as the main house, we size for combined peak demand rather than the main house alone. Where the existing venting is outdated or shared with another appliance in a way that no longer meets current code, we address that as part of the job rather than leaving it for a future problem.
Cost for a gas storage tank replacement depends on size, vent type, and site access, and is quoted after a short in-home assessment; where a tankless unit is the better fit given space or demand, that installation typically runs a ballpark of $3,500 to $7,500, which is a ballpark, not a quote.
Safety note
If you ever smell gas, hear a hissing sound near a gas appliance, or notice a burner flame that looks mostly yellow instead of blue, leave the home right away and call FortisBC at 1-800-663-9911 from a safe location before doing anything else. Gas piping, venting, and combustion equipment must only be installed, repaired, or adjusted by a Technical Safety BC licensed gas fitter.
The manufacture date is usually stamped on a data plate on the tank itself, and a technician can help you locate and read it during a service visit if you're not sure.
Yes, this is common, but it needs to be sized for combined peak demand from both units, which is worth reassessing if a suite was added after the original tank was installed.
This usually points to corrosion inside the tank itself, which is a sign the unit is nearing the end of its working life rather than something that can be repaired.
Not always, but if the existing venting is shared, undersized, or doesn't meet current clearance requirements, it needs to be addressed as part of the replacement.
A like-for-like swap with no venting or gas line changes is often done in a few hours, while jobs requiring code updates take longer.
It depends on what's failed. A minor part like a thermocouple is often worth repairing, but if the tank itself shows corrosion or the unit has had repeated issues, replacement is usually the better long-term value.
