A good water heater quote should answer more than "how much." Here are the licensing, permit, sizing, and warranty questions every Metro Vancouver homeowner should ask before signing off on installation or replacement.

Quick answer: Before hiring a water heater contractor in Metro Vancouver, ask about their Technical Safety BC gas licence number, whether they'll pull the required permit, what brand and size they recommend and why, whether the quote is fixed or estimated, what the warranty covers (parts vs. labour), and whether they carry liability insurance and WorkSafeBC coverage. A written, itemized quote protects you from surprise costs.

A water heater replacement is not a purchase most homeowners make often, which makes it easy to focus only on price and miss details that matter more over the next 10-15 years: correct sizing, proper venting, and whether the person doing the work is actually licensed to touch a gas line. In Metro Vancouver's older housing stock, condos, and townhomes, mechanical rooms are often tight and venting runs are not always straightforward, so the questions you ask upfront can prevent a rushed or undersized installation. A contractor who welcomes detailed questions and answers them clearly is usually the one worth hiring.
Any contractor doing gas water heater work in BC must hold a valid Technical Safety BC gas licence, and it is reasonable to ask for the licence number directly. Confirm they carry liability insurance and WorkSafeBC coverage, since this protects your home and you as the homeowner if something goes wrong on the job. Ask whether the technician doing the actual work is Red Seal certified or working under direct supervision of someone who is. A contractor with nothing to hide will give you this information without hesitation.
The right water heater size depends on household size, peak hot water demand, and available space and venting, not just the size of the unit you already have. Ask the contractor to explain how they calculated the recommended tank size or, for tankless, the flow rate in gallons per minute your household needs. If you're considering switching from tank to tankless, or from electric to gas, ask what changes to venting, gas line sizing, or electrical service that switch would require, since those add-on costs matter as much as the unit price itself.
| Question | Why It Matters |
|---|---|
| What size or flow rate do you recommend, and why? | Undersized units run out of hot water; oversized units waste energy |
| Tank or tankless for my household? | Tankless needs different venting and gas line sizing |
| What brand and model, and is it in stock? | Availability affects install timeline |
| Does my existing venting meet current code? | Older homes often need venting upgrades |
| Will you need to modify the gas line? | Gas line work must be done by a licensed gas fitter |

📞 (604) 359-1081 Request a free quoteAsk for a written, itemized quote rather than a verbal ballpark, and ask what it includes: the unit, labour, permit fees, disposal of the old tank, and any venting or gas line modifications. As a general reference point for Metro Vancouver, installed tankless water heater installation typically runs in the $3,500-$7,500 range, though your exact price depends on sizing, venting complexity, gas line changes, and permit requirements specific to your home. If a quote seems unusually low, ask what's excluded, since gas line or venting upgrades discovered mid-job are a common source of surprise charges. A contractor offering a free written quote before any work begins is giving you the clearest way to compare against other bids.
Ask what warranty covers the tank itself versus the labour to replace it if something fails, since these are often different lengths from different parties (manufacturer vs. installer). Ask whether the contractor recommends any follow-up maintenance, such as annual flushing to manage sediment from Metro Vancouver's moderately hard water, or installation of an expansion tank if your home doesn't already have one. It's also worth asking about current rebate programs: the Canada Greener Homes grant is closed to new applicants, but the Canada Greener Homes Loan (interest-free, up to $40,000) and the Oil to Heat Pump Affordability program may apply depending on your situation, along with CleanBC, BC Hydro, and FortisBC rebates for qualifying equipment. Ask the contractor to confirm exact current figures and eligibility at quote time, since program details change.
Before calling a contractor, homeowners can safely check a few things themselves: whether the pilot light is out on an older tank, whether there's visible water pooling at the base of the tank, the age of the unit (usually on a manufacturer sticker), and roughly how much space is available in the mechanical room or closet. What should never be attempted without a licensed technician is disconnecting or reconnecting gas lines, adjusting gas pressure, modifying venting or flue pipe, or working on the electrical connection for an electric or hybrid unit. BC gas and electrical code requires licensed trades for this work, both for safety and because unpermitted gas work can affect home insurance and resale.
⚠️ Safety note: If at any point during a water heater inspection or installation you smell gas (a rotten-egg odor), do not operate switches or the water heater itself — leave the home immediately, do not attempt to relight anything, and call the FortisBC gas emergency line at 1-800-663-9911 from outside the house. Gas water heater work in BC legally requires a Technical Safety BC-licensed gas fitter; never let an unlicensed handyman connect or move a gas line, flue, or venting. If a gas water heater has ever produced soot, a pilot light that won't stay lit, or you experience headache/dizziness/nausea near the unit, treat it as a possible carbon monoxide concern — leave for fresh air and have a licensed technician inspect the venting before restarting the appliance.
