New Westminster's dense heritage housing stock means a lot of the boilers CANRO repairs here are decades old, which shapes both the typical fault and the fix.

Quick answer
A Slant/Fin boiler repair in New Westminster typically runs $250–$1,800, with most jobs landing between $400–$900, plus the $90–$150 diagnostic visit most shops credit toward the repair. Treat that as a 2026 market ballpark rather than a firm price — CANRO's office sends a certified gas technician to confirm the actual number after a short on-site look.

Queens Park, the Brow of the Hill, and other established New Westminster neighbourhoods carry a lot of boilers that are original to homes built well before modern hydronic standards, which means repair visits here often involve older-generation parts and piping.
A clean part swap on an accessible older unit sits toward the lower end. Cost rises when a part has to be sourced for a discontinued or older model, when narrow lots and tight basements slow access for equipment or parts, or when a circulation complaint turns out to be sludge throughout the original piping rather than a single failed component.
On a heritage home with an aging boiler, CANRO looks closely at whether the cast-iron radiators and piping are still in good shape before recommending repair versus replacement — if they are, a straightforward repair or even a full boiler swap onto that existing system usually makes more sense than a bigger renovation.
The City of New Westminster doesn't typically require a permit for a standard repair. On some older, narrower properties, confirming vehicle parking and equipment access ahead of the visit helps keep a repair call on schedule.
Diagnosis includes testing the suspect component, checking the condition of original piping for sludge or corrosion, and inspecting venting for moisture-related wear. On any heritage system, a technician also confirms whether a part is realistically available before quoting a repair rather than discovering a sourcing problem partway through the job.
On narrower properties, a technician also plans exactly how a replacement part will get from the street to the mechanical room before the visit, rather than working that out on arrival, since some of these older basements only allow one practical route in.
If a New Westminster boiler is already on its second or third repair in a couple of years, it's worth asking directly whether the unit is approaching the point where a planned replacement, done on your schedule rather than during a breakdown, makes more sense than continuing to chase individual faults one at a time.
Safety note
Boiler repair work involves gas piping, combustion, and venting. If you ever smell gas, hear an unusual burner sound, or suspect a carbon monoxide problem, leave the house immediately and call FortisBC at 1-800-663-9911. Diagnosis and repair on a gas boiler must be done by a Technical Safety BC licensed gas fitter — CANRO holds both a gas licence and a boiler licence.
This is often sludge buildup in original piping that's never been flushed, rather than a single failed part — a technician can flush the system to confirm and resolve it.
It depends on the specific model and age — for some older units, sourcing a matching part becomes harder, which is part of an honest repair-versus-replace conversation.
Higher humidity can accelerate corrosion on exposed flues or fittings in older systems, which a technician checks as part of a thorough repair visit.
If sludge is contributing to the fault, a flush alongside the repair can prevent the same issue recurring quickly — a technician will recommend it when it's actually warranted, not by default.
Access can add some time on tight, older properties, though it's usually a smaller factor than the part and diagnostic cost itself.
A technician checks for leaks, sludge, and general condition during a repair visit, which is the reliable way to know rather than guessing from the piping's age alone.
