What Burnaby homeowners typically pay to repair a Laars boiler, and the parts most likely to fail in older local homes.

Quick answer
A typical Laars boiler repair in a Burnaby home runs $250 to $1,800, with most jobs falling between $400 and $900, plus a $90 to $150 diagnostic visit that is usually credited toward the repair. That is a 2026 public-market ballpark, not a quote — CANRO's certified technicians, based right here in Burnaby, confirm your exact price after inspecting the boiler.

Burnaby's building stock spans nearly a century, and that shows up in repair calls. In character homes from the 1920s through 40s around neighbourhoods like Capitol Hill or the Heights, cast-iron radiator systems paired with an older boiler can develop circulator pump or zone valve issues after years of steady use. In 1960s and 70s bungalows, control boards and igniters are common failure points as original equipment ages out. Newer installs, including those serving laneway homes, more often see diverter valve or expansion tank issues tied to the added domestic hot water load these secondary dwellings put on a shared system.
Because Burnaby's water is soft, scale-driven heat exchanger failures are somewhat less common here than in harder-water communities, though age and normal wear still apply.
| Item | Typical ballpark (CAD) |
|---|---|
| Diagnostic / service call | $90 – $150 (often credited to the repair) |
| Typical repair bill | $250 – $1,800 (most $400 – $900) |
| Igniter / flame sensor | $100 – $400 |
| Zone valve replacement | $300 – $650 |
| Gas valve replacement | $200 – $1,100 |
| Licensed labour rate | $95 – $165 per hour |
For most Burnaby homeowners, a repair in the typical $250 to $1,800 range on a Laars boiler that has otherwise run reliably is the sensible choice, especially given how gentle the local soft water is on these systems over the long run. The conversation shifts once a heat exchanger is involved, or a boiler well past a decade old needs its second or third major repair — at that point ask your technician to lay out the repair cost against a full install so you can decide with real numbers rather than guesswork.
Since CANRO is based in Burnaby, response times here are typically efficient. Describing your exact symptom when you call — cold radiators in one room, a boiler that will not start, or a leak near the boiler — helps the technician bring the right parts on the first trip.
Safety note
Boiler repairs, especially anything involving the gas valve, ignition or venting, must be performed by a Technical Safety BC licensed gas fitter. If you ever smell gas, leave the home immediately and call FortisBC at 1-800-663-9911. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.
Igniter and flame sensor issues are among the most common and least expensive repairs, alongside zone valve problems on multi-zone systems in older homes.
Soft reservoir water does reduce scale buildup compared to harder-water regions, which can mean fewer heat-exchanger-related repairs over a boiler's life, though it does not eliminate normal component wear.
Most repairs fall between $250 and $1,800, with the majority landing in the $400 to $900 range depending on the part involved.
Yes, the $90 to $150 diagnostic visit is typically credited toward the repair cost once you approve the work.
It can add complexity since the shared system carries more domestic hot water demand, so a technician checks the diverter valve and controls carefully when diagnosing an issue.
If the repair involves the heat exchanger, or the boiler is over a decade old and has needed multiple major repairs already, it is worth comparing against the cost of a new installation.
