Why Leak Repair Costs Vary So Much
There is no single price for a water heater leak, because the word leak covers everything from a 20-minute valve swap to a full tank replacement. The cost depends on what is leaking, how accessible the unit is, whether parts are seized or corroded, and whether your installation needs to be brought up to current BC code.
In Greater Vancouver, labour rates, parts availability, and the condition of older homes all play a part. A tank tucked into a tight crawlspace costs more to work on than one in an open garage. That is why we quote each job specifically rather than throwing out a figure that may not fit your situation.
Typical Cost Ranges by Scenario
These are general ranges to help you set expectations. They are not quotes — your exact cost depends on your unit and your home.
Drain valve replacement: a lower-cost repair, since the part is inexpensive and the job is quick when the valve is accessible.
T&P valve replacement or expansion tank install: a modest range, higher if a pressure-reducing valve is also needed.
Tightening or replacing inlet/outlet connections and unions: generally a lower-to-moderate range, depending on whether fittings are corroded or seized.
Full tank replacement (tank has rusted through): the largest range, driven by tank size, venting requirements, and any code upgrades to the gas line, venting, or seismic strapping.

The Hidden Costs People Forget
The repair itself is only part of the picture. A leak that has run for a while can soak into flooring, drywall, and subfloor — common in older Lower Mainland homes — and water damage remediation is a separate cost from the plumbing fix.
Code upgrades are another factor. When an old tank is replaced, current BC requirements for venting, expansion tanks, drain pans, and seismic strapping may apply, and those can add to a replacement that looks simple on the surface. A reputable technician will flag these up front so there are no surprises. The cheapest quote that skips required code work is not actually the cheapest.
Accessibility and disposal add to the picture too. A tank wedged into a finished closet or a low crawlspace takes longer to remove and install than one sitting in an open garage, and the old unit has to be hauled away and recycled responsibly. None of these are reasons to delay a needed repair — they are simply why two homes with the same leak can see different totals, and why an in-person assessment beats a number pulled off a generic price chart online.
How to Get an Accurate Quote
The fastest way to a real number is to give us the details: the age of the unit, the tank size, where the water is coming from, and a photo if you can. With that, CanroHeat can scope the job accurately and give you a firm price before any work begins.
Beware of anyone who quotes a leak sight-unseen or pressures you toward an immediate replacement without diagnosing the source. A drain-valve drip and a perforated tank are worlds apart in cost. Tank and tankless water heaters are serviced by our parent company CanroHeat — call 604-359-1081 for an honest, itemized quote with no surprises.
