Tank replacement in Grandview Heights is usually a clean swap given the neighbourhood's newer construction, though suite demand changes the sizing conversation.

Quick answer
Replacing a gas hot water tank in Grandview Heights typically runs $1,800 to $3,200 for a standard vent tank, or $2,500 to $4,500 if power-venting or venting changes are needed. That's a ballpark from 2026 public market data, not a quote — CANRO's certified gas technicians confirm the actual price once they've assessed your existing tank and venting.

Most Grandview Heights homes were built with modern venting and gas piping already in place, so a like-for-like tank swap is usually the lower end of the range — the existing flue and gas connector typically already meet current code. The bigger variable in this neighbourhood tends to be sizing rather than venting: many homes here run a legal suite or coach house, and the original tank may have been sized for the main house only.
| Scope | Ballpark (CAD) |
|---|---|
| Standard atmospheric-vent tank, like-for-like | $1,800–$3,200 |
| Power-vent tank or venting change | $2,500–$4,500 |
| City of Surrey permit | $75–$200 |
If the household has grown, or a suite was added after the original tank was installed, a same-size replacement may just repeat an undersized setup. This is worth flagging to the technician doing the replacement so they can properly size the new tank for actual current demand — main house plus suite — rather than defaulting to matching the old unit.
Homeowners weighing the shared-tank-versus-two-tanks decision sometimes find it helpful to track actual hot water usage for a week or two before deciding, since assumptions about peak demand don't always match reality — a suite tenant's schedule might not actually overlap with the main household's as much as expected, which can tilt the decision back toward a single larger shared tank instead of two separate units.
A family that's added a basement suite since their original tank was installed calls because hot water runs short most evenings. The existing tank, sized correctly for the main house alone, simply can't keep up now that a second household draws from it too. The replacement conversation here usually includes whether to install one larger shared tank or give the suite its own dedicated unit, weighing upfront cost against long-term convenience for both households.
Because the home is newer, venting and gas line work are rarely needed — the job is really about getting the sizing decision right the second time around.
Timing the replacement matters too. Doing it proactively, once a tank is showing early warning signs like a slower recovery rate or a faint rumble, generally means a scheduled daytime appointment rather than a Sunday-night emergency call after the tank has already started leaking onto a finished basement floor, which is a far more disruptive way to have this conversation.

Safety note
If you ever smell gas near a boiler or water heater, get everyone out of the house first, then call FortisBC at 1-800-663-9911 from outside. Don't attempt to locate or fix a suspected leak yourself.
Possibly — sizing should account for total household demand including the suite, not just the main house.
Yes, the City of Surrey requires a permit and inspection for gas water heater replacement.
A straightforward like-for-like swap is typically a few hours in a newer home with good access.
Rust-coloured water or a leak at the base of the tank means the tank body has failed and needs replacing, not repairing.
That's a reasonable option in some layouts, especially if simultaneous demand is high — worth discussing with the technician doing the assessment.
Usually, since venting is typically already up to current code, though upgrading tank size or type can still require adjustments.
