Gas Leak Detection

When Gas Leak Detection Is the Right Follow-Up

• A utility or emergency responder isolated or tagged part of the gas system. Share the notice, reference number and description of what was shut off so the follow-up begins with the known system status.
• A defined section failed a pressure test. Detection may help investigate the tested scope, while additional sectional testing may be needed to narrow the question. See Gas Line Pressure Testing.
• Visible damage or recent work raises a non-active concern. Renovation, drilling, impact, excavation, fire or flooding may justify assessment after the scene is safe. Appearance alone does not prove that gas is escaping or decide the repair scope.
• The suspected source remains unresolved. A defined investigation can separate accessible observations, measured results, inaccessible areas and uncertainty before a repair decision is made.
• A valve, connection, appliance landing point or branch is in question. The result may remain within detection, or it may route to repair, pressure testing, installation or appliance-specific service.

An intermittent or faint odour does not establish size or severity. If gas is suspected now, leave and call FortisBC from outside. Do not remain inside to investigate.

Natural Gas and Carbon Monoxide Require Different Responses

Natural gas is given an odour that may smell like rotten eggs or sulphur. If you smell it or otherwise suspect a gas leak, leave and call FortisBC or 911 from outside. Do not try to determine the source or severity yourself.

Carbon monoxide is colourless and odourless. A carbon-monoxide alarm or suspected exposure is a separate combustion and venting emergency, not proof of a piping leak. Get everyone outside, call 911 or FortisBC from outside, seek medical attention for symptoms and do not re-enter or troubleshoot equipment until emergency responders say it is safe.

Gas leak detection does not automatically diagnose appliance operation, combustion or venting. When the concern points to a water heater or another fuel-burning appliance, the follow-up must address that appliance and its venting under the appropriate service scope.

What the Investigation Should Clarify

1. Whether emergency response comes first. An active suspected gas leak is routed to FortisBC or 911, not to contractor booking as the first action.
2. The defined investigation scope. The visit should begin with the known finding, system status, affected area, accessible piping and any utility, responder or inspection notice.
3. The evidence and its limits. Observations and measurements should be separated from inference, inaccessible areas and remaining uncertainty. The methods used should match the actual question.
4. Whether pressure testing is relevant. When a tightness test is needed, the scope and purpose should be stated. The result should not be extended to untested piping, capacity, appliance operation or future condition.
5. Which service owns the next step. A confirmed defect belongs to repair. A defined tightness question belongs to pressure testing. A new or unsuitable route belongs to installation. An appliance landing or commissioning concern belongs to appliance connection or the applicable appliance category.
6. Which authorization route may apply. If the findings lead to regulated work, the applicable permit or authorization process depends on the scope and jurisdiction. The address and actual work must be confirmed before stating the route.
7. What remains unresolved. The homeowner should understand what was inspected, what evidence was found, what remains inaccessible or uncertain and what condition must be addressed before any affected system is returned to service.

What Affects Scope and Price

The scope and price depend on the question the investigation must answer. Important factors include:

• What FortisBC, emergency responders or a previous contractor isolated, tagged, tested or reported.
• Whether the concern involves one connection, one branch, a defined tested section or a broader unresolved scope.
• Access to piping, valves and connections, including finished areas, crawlspaces, exterior routes and buried piping.
• The number of branches and appliances affected by isolation or follow-up work.
• Whether a defined pressure test or additional sectional investigation is needed.
• Whether the findings route to repair, installation, appliance connection or regulated follow-up work.
• Property access, shared-system coordination and authorization requirements for detached, rental, townhouse, apartment or other strata settings.

An estimate should state the intended investigation scope and identify the findings that could change it. No single duration, instrument set or repair path fits every suspected leak.

Property Conditions That Change the Investigation

Property details are more useful than assumptions based on a city, neighbourhood or construction era. Relevant questions include:

• Which gas piping, appliances and shutoffs are original, and which were added, relocated or replaced during renovations?
• Is the property detached, a rental, a townhouse, an apartment or another strata setting?
• Who controls the affected shutoff, piping, common area and access process?
• Does the route pass through a crawlspace, finished wall or ceiling, garage, addition, exterior area or buried section?
• Did drilling, excavation, impact, fire, flooding or building work occur near the route?
• What utility, responder, permit, inspection or previous service records are available?

A construction era can prompt questions about renovation history, but it does not prove the piping material, condition or cause. Shared-property responsibility and the authorization route must be confirmed from the actual component, property documents, address and work scope.

How is gas leak detection priced?

The price depends on the defined investigation scope, access, affected branches and appliances, testing needs and whether the findings route to another service. Ask what the estimate includes and which findings could change the scope.

What to Prepare After the Scene Is Safe

After FortisBC or emergency responders say the immediate scene is safe, gather information that can define the follow-up:

• Any utility, emergency-response, inspection or previous-service notice, tag or reference number.
• What was smelled, heard or observed, recorded from memory rather than through re-entry.
• What the utility or responder shut off, isolated or tagged.
• Which appliances were operating before the concern.
• Recent renovation, appliance replacement, drilling, excavation, impact, fire or flooding near the gas route.
• The property type, access conditions and any strata, rental or shared-system contact.
• Existing gas, appliance, permit or service records.
• Appliance details and photographs only when the area is safe to access.

Do not re-enter a suspected area, remove a lock, operate gas equipment or collect photographs from an unsafe location. Use information available from outside, existing records and the responder handoff.

Schedule Gas Leak Detection

If you smell gas or hear hissing now, leave and call FortisBC at 1-800-663-9911 or call 911 from outside. Do not wait for a contractor appointment.

After the active scene is safe, share the service address, utility or responder notice, system status, property type, recent work and known access limits. Schedule Your Plumber or Call The Crazy Plumber at (236) 552-0190.
