A natural gas boiler replacement in Kerrisdale generally falls in a wide ballpark, and the final figure depends on venting, zones, access and the state of the existing piping.

Quick answer
A natural gas boiler replacement in Kerrisdale in 2026 is generally in the ballpark of $7,500 to $15,000+, ballpark, not a quote, confirmed by the CANRO office after a short assessment. Where a house falls in that range depends on venting, the number of heating zones, the condition of the existing piping and radiators, and how easy the mechanical room is to work in.

For a like-for-like gas boiler replacement in Kerrisdale, the ballpark is $7,500 to $15,000+, ballpark, not a quote. The CANRO office confirms an actual figure after a short assessment of the house, because two boilers that look the same from the basement stairs can involve very different work behind the walls.
What moves the price is rarely the box itself. It is the venting route, the number of zones and pumps, the pipework that has to be modified to suit the new boiler, any required permits and inspections, and how much time the crew spends working around a tight or finished space. A straightforward swap in an open basement sits near the lower end. A rebuild with several radiant manifolds, a buried vent route and an indirect water heater sits much higher.
Timing also plays a role in how the process feels rather than what it costs. In October the heating trades are busy but not yet overwhelmed, a replacement can be planned for a specific day, and the house is not yet at risk of a hard cold spell while the old boiler is out. By mid-winter, a failed boiler can mean temporary heat and a rushed decision, which is the situation to avoid if you can.

Kerrisdale has two broad housing types that sit beside each other. There are the established houses from the middle of the last century, often with plaster walls, brick chimneys, cast-iron radiators and a boiler in a basement room that was designed around an older appliance. And there are large rebuilds, with several floors, multiple zones, radiant floors in bathrooms and living areas, and a boiler that may also serve an indirect water tank.
In the older houses the cost question is often about the chimney. If the old boiler vented into a masonry flue, a modern replacement will normally need a new venting route, and getting that through finished walls or around joists affects labour. Old iron piping may be reused, but it may also need flushing, isolating and some replacement of aged valves. In the rebuilds, the question is more about the controls, the number of zones and how much of the existing manifold work needs to be touched. Replacing a boiler in a house with a complicated radiant layout needs careful balancing after the swap.
Another Kerrisdale detail is how the house is heated overall. Some of the older houses have been converted in part to forced air with a boiler still serving a portion of the radiators, and sorting out which loops the new boiler needs to serve is part of the assessment. A technician who looks at the whole picture before pricing tends to produce a quote that does not change on the day.
| Factor | Tends to lower the cost | Tends to raise the cost |
|---|---|---|
| Venting | Short, direct run to an exterior wall | Long run, chimney abandoned, finished walls to open |
| Zones and controls | One or two zones, simple thermostat | Many zones, radiant manifolds, mixing, indirect tank |
| Piping condition | Clean, sound pipework that can be reused | Corroded valves, sludge, leaks that must be fixed |
| Access | Open basement, clear route for equipment | Tight room, stairs, finished space, restricted parking |
| Gas supply | Existing line suits the new boiler | Line needs upsizing or rerouting |
| Condition of system water | Clean | Heavy sludge needing a flush |
| Permits and inspection | Standard | Additional work flagged by the inspector |
The table speaks in qualitative terms because no one can honestly quote a number for a house they have not seen. The $7,500 to $15,000+ ballpark is the honest framework.
Do not compare totals only. Ask each contractor to list what is in the price: the make and rated output of the boiler, the venting material and route, the pump and expansion tank, the controls, the permit, the warranty terms as the manufacturer states them, and who handles the inspection. A very low quote that leaves out the venting or the permit is not low. Look for quotes that explain why the boiler was sized the way it was, based on the house and not a rule of thumb.
It is reasonable to ask whether the boiler is a condensing type, where the condensate will drain, what happens if the inspector requires changes, and how the old piping condition was assessed. Warranty terms are set by the manufacturer, so ask to see the certificate rather than relying on a verbal summary.
A boiler repair is usually in the range of a few hundred dollars up to roughly $1,800, with most jobs well below that. The question is not whether a repair is cheaper than replacement today, but whether the repair buys real life. A new circulator on a sound boiler is a sensible repair. A cracked heat exchanger on an old boiler is usually the end of the road, since the repair can cost a large fraction of a new unit.
Replace rather than repair when the boiler is old and leaking from the body, when failures are repeating, when the venting is no longer to current standards, or when the boiler cannot be parts-supported. Plan replacement for a quiet season if you can, since summer work is easier to schedule. A boiler discovered to be failing in October can still be replaced before winter, and a technician can often keep a marginal system running safely while the work is arranged.
Safety note
If you smell gas, leave the house immediately, avoid switches and phones inside, and call FortisBC at 1-800-663-9911 from outside. If a carbon monoxide alarm sounds, get everyone out and call 911. Boiler replacement and gas piping must be done by a Technical Safety BC licensed gas fitter under a City of Vancouver permit.
The ballpark is $7,500 to $15,000+, ballpark, not a quote. The CANRO office confirms the figure after a short assessment, because venting, zones and access change the work.
Because the work varies. A simple swap in an open basement and a multi-zone radiant house with a new vent route are very different jobs.
A proper quote lists the gas permit and inspection. Confirm that it is included so you can compare quotes fairly.
Often yes. The radiators are usually sound, and the work is in connecting a new boiler to them correctly and flushing the system.
A straightforward replacement generally runs a day or two on site. Houses with complicated piping or new venting routes can take longer, and the technician will tell you after the assessment.
If the boiler is failing, leaking or unsafe, October is a good time. If it is simply old but passes inspection, waiting is a legitimate choice. A tune-up will show which situation you are in.
