What replacing an aging gas boiler costs for a Hamilton, Richmond homeowner, and what determines where you land in the range.

Quick answer
A full boiler replacement in Hamilton, Richmond typically runs $7,500 to $15,000 or more as a 2026 ballpark based on public market data, not a quote, plus a City of Richmond gas permit usually around $75 to $200. CANRO's certified technicians confirm the exact figure after assessing your existing system.

Hamilton is one of Richmond's older residential pockets, built on low, flat Fraser River delta land with a persistently high water table. A lot of the boilers CANRO evaluates here are original to mid-century builds and have spent decades in crawlspace or ground-level mechanical rooms where ground moisture is a bigger factor than in a drier, elevated basement elsewhere in the region. That combination of age and environment means piping and structural components around the boiler sometimes need attention alongside the unit itself when it's time to replace.
Newer infill homes in the area tend to have better-sealed, drier mechanical spaces, so the replacement conversation there is usually driven by straightforward age and efficiency rather than moisture-related wear.
| Item | Ballpark range |
|---|---|
| Boiler replacement, full job | $7,500 – $15,000+ |
| City of Richmond gas permit | $75 – $200 |
Where a job lands in that range depends on the size and output the house actually needs, whether existing piping is being reused or needs updating, and how much venting and gas line work is required to bring the install up to current code. A straightforward swap in an accessible mechanical space sits toward the lower end; a job needing piping repairs or elevated equipment placement to address flood-level concerns runs higher.
For a boiler under about 12 years old, another repair almost always makes more financial sense than replacement. Given how many Hamilton systems are original to older builds and have spent years in a ground-moisture-heavy environment, a boiler past 15 years with a failed heat exchanger or a pattern of repeat repairs is usually a stronger case for replacing outright — a heat exchanger repair alone can approach a meaningful share of a new system's cost.
The job covers a proper load calculation to size the new boiler, removal and disposal of the old unit, assessment and any needed upgrades to gas line and venting, connection to existing or updated piping, the City of Richmond gas permit, full commissioning and combustion testing, and a controls walkthrough. All work is performed by a Technical Safety BC licensed gas fitter — CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.
Safety note
Boiler replacement involves gas connection, venting, and combustion equipment that must meet Technical Safety BC code. If you smell gas at any point, leave the house and call FortisBC's emergency line at 1-800-663-9911.
It can influence where equipment is placed — sometimes elevated above typical ground level as a precaution — which a technician will discuss as part of the assessment.
Most gas boilers are reasonable candidates for replacement somewhere in the 15 to 20 year range, though ground moisture exposure in crawlspace installs can be an additional factor in older homes here.
Yes, the City of Richmond requires a gas permit and inspection for boiler replacement work.
Sometimes, especially if the existing piping has corrosion from years of ground moisture exposure; a technician assesses this during the site visit.
A straightforward swap typically takes one to two days; jobs involving piping repairs or equipment elevation can take longer.
FortisBC and CleanBC programs exist and change over time; confirm current eligibility rather than assuming a past program applies.
