If You Smell Gas, Do This First
A rotten-egg odor, hissing near a gas line, dead grass over buried piping, or unusual appliance behavior can all point to a leak. Take those signs seriously.
If you smell gas or suspect a leak:
- Leave the home or building right away.
- Do not turn lights or switches on or off.
- Do not use phones, appliances, lighters, matches, or electrical switches inside.
- Move a safe distance away from the building.
- Call 911 and your gas utility from outside.
- Call Caputo Mechanical after emergency responders have handled the immediate hazard and it is safe for service.
Caputo does not replace your gas utility or emergency services. Utilities often handle emergency investigation and meter-side response. Caputo helps locate and correct problems on the building side of the system: piping, valves, fittings, and appliance connections.
If you notice a rotten-egg odor and are not sure whether it is natural gas, sewer gas, or a water heater issue, read Caputo’s guide to rotten egg smell in your house. If the smell is strong or you are unsure, leave first and treat it as a safety issue.
What Professional Gas Leak Detection Covers
Gas leak detection means finding, confirming, and documenting a leak or unsafe condition in the piping or appliance connection system. That can include exposed piping, shutoffs, fittings, valves, connectors, and lines installed or repaired during a remodel.
It could be something as simple as a loose appliance connector, damaged buried line, corroded pipe, or a run that was never sized for the appliance load. Professional detection answers the practical questions:
- Is there an active leak on the customer-side piping?
- Is the smell coming from an appliance connection or somewhere else?
- Does the line need repair or replacement?
- Is the issue tied to recent installation work?
- Does the system need further inspection or pressure testing?

Signs You May Have a Gas Leak
Natural gas utilities add odorant so leaks are easier to notice, but smell alone is not a perfect detector. Odor can fade, get masked, or be harder for some people to pick up.
Common warning signs include:
- Rotten-egg or sulfur-like odor near appliances or throughout the building
- Hissing or whistling near a gas line, meter, valve, or appliance
- Dead or discolored grass near a buried gas line
- Dirt or dust blowing up from the ground near an underground line
- Pilot lights that keep going out
- Gas appliances that will not operate normally
- Headaches, nausea, or dizziness that improve after you leave the area
- An unexplained rise in gas usage
A carbon monoxide detector is not a natural gas detector. CO detection matters, but it does not replace the steps above if you suspect a gas leak.
What Happens During a Gas Leak Detection Visit
Every property is different. In general, Caputo’s technician starts by learning what you noticed, where the concern began, and whether the utility or emergency responders already visited.
A visit may include:
- Visual inspection of accessible gas piping and fittings
- Checks around appliance connectors, shutoffs, and valves
- Electronic leak detection where it fits the situation
- Bubble testing in suitable areas
- Pressure testing when the job calls for it
- Isolating affected sections when possible
- Clear recommendations for repair, replacement, or further inspection
If a leak is found, Caputo can provide gas line repair or gas line replacement as needed. For urgent work, see emergency gas line repairs.
Leak Detection, Repair, and Emergency Service
These services are related, but they answer different questions:
- Leak detection: Where is the problem, and what is causing it?
- Repair: How do we fix it safely?
- Emergency service: What happens when this cannot wait?
A faint odor near a stove may lead to connector and shutoff checks. Damage in an older line may mean pipe repair or replacement. A strong odor throughout the home usually means utility and emergency response first, before any contractor work begins.
Local Service for Nashville and Middle Tennessee
Caputo Mechanical is based in Old Hickory and works throughout Middle Tennessee. Homes and commercial buildings here range from older gas piping to newer appliance additions and outdoor lines for grills, fire pits, generators, pool heaters, and outdoor kitchens.
That variety is why leak detection is not a one-size checklist. A technician needs the layout, appliance load, line age, recent work, and where the issue shows up.
Caputo can help with:
- Suspected leaks around stoves, ranges, water heaters, furnaces, fireplaces, grills, and other gas appliances
- Follow-up repairs after utility safety checks
- Repair and replacement recommendations
- Inspection of building-side piping before or after remodels
- Commercial gas piping concerns where appropriate

FAQs About Gas Leak Detection
What should I do first if I smell gas?
Leave the building immediately, avoid switches and electronics inside, and call 911 and your gas utility from a safe place. After the emergency concern is handled, call Caputo at (615) 209-9196 for detection, repair, or follow-up service.
Can Caputo come out before I call the utility?
If you suspect an active leak, call the utility and emergency services first. Caputo can inspect, detect, repair, or replace building-side piping once the area is safe.
Is gas leak detection the same as gas line repair?
No. Detection finds or confirms the source of a suspected leak. Repair fixes the damaged or unsafe line, fitting, valve, or connection after the problem is identified.
Does a carbon monoxide detector detect natural gas?
Usually no. Carbon monoxide detectors and combustible gas detectors are different tools. Do not use a CO detector to decide whether a gas odor is safe.
Can I use soap bubbles to check for a gas leak?
Some DIY guides mention soap-bubble checks, but they are not a substitute for leaving the building and calling the utility when a leak is suspected. Gas work belongs with trained professionals.
What if the rotten-egg smell might be sewer gas?
Caputo’s rotten-egg smell guide covers gas, sewer, water heater, and drain-related causes. If the odor could be natural gas, leave first and treat it as a safety issue.
Do gas leaks always smell like rotten eggs?
No. Odorant helps people notice gas, but smell can fade or get masked. Hissing, dead vegetation, and appliance problems can also signal a gas issue.
