A 1954 build is 72 years old. A house of this age usually has supply pipes as old as the building, and a repipe is a five figure job. Here is what tends to be true at that age, what each one costs in 2026 Canadian dollars, and the sentence to say to the agent.
Ordered by what tends to matter most.
Homes heated with oil before about 1975 often had the tank abandoned in place when they converted to gas rather than removed. A leaking buried tank is an environmental problem rather than a repair, and it is the single item in this list most likely to stop a policy being written until it is resolved.
Removal runs $1,800 to $3,000, to remove, with soil remediation commonly $5,000 to $15,000 and documented cases far beyond that.
Look for a fill pipe or vent stub poking out of an exterior wall, and for capped copper fuel lines at the basement wall. If the listing says converted to gas, the question is whether there is removal paperwork.
Say this to the agentWas this house ever heated with oil, and if it was, is there a record of the tank being removed and the soil tested?
Homes from before the 1960s were commonly plumbed in galvanized steel. It rusts closed from the inside over decades, so the symptoms are weak pressure, brown water after the house has sat, and eventually leaks. Unlike most things on this list it degrades on a schedule rather than by chance.
A whole house repipe runs $6,000 to $18,000, and $10,000 to $20,000 in Metro Vancouver, where the labour rates are higher.
Galvanized is dull grey, has threaded joints, and a fridge magnet sticks to it. Copper and PEX are the good answers. Check at the water heater and under a sink.
Say this to the agentWhat are the supply pipes made of, and how much of the original pipe is still in the walls?
Houses of this age were often built with 60 to 100 amp service, and a fuse box rather than breakers is a common sign of it. A hundred amps is the modern minimum, so a smaller service is less a safety problem than a limit on what the house can run and a cost waiting on any renovation.
Upgrading the panel and service is $1,500 to $4,000, plus the Hydro disconnect and the ESA permit on top.
The main breaker at the top of the panel has the amperage printed on it. If there are fuses rather than breakers, that answers it a different way.
Say this to the agentWhat is the service amperage, and has the panel ever been upgraded?
This is what is typical for the year. It is not a finding about this house.
Photographs of the panel, the basement and the water heater would tell you whether any of it applies here.
Every dollar figure on this page comes from the Casaroo repair cost dataset, published openly with its methodology, version and licence. Each item links to the guide that lists its own sources. Figures are 2026 Canadian dollars and are ranges, not quotes.
That is what is typical for the year, and it is the part almost nobody walks in knowing. It is not yet what is true of the house in front of you. The next step is how you find that out.
The order to walk the rooms so you do not double back, what to photograph at each stop, what a bad answer sounds like, and the exact sentence to say out loud. Read it on your phone with one hand.
One email unless you tick the box. No list, no newsletter, and nothing above is held back if you would rather not.
