Gas Leak Detection

FlowFast connects you with an independent local plumber who systematically traces the system to find the exact leak location so it can be repaired safely.

View all Gas Lines servicesA suspected gas leak is the one plumbing problem where the order of operations matters most: safety first, detection second. If you smell gas right now, leave the home and call the gas utility or emergency services from outside before reading further. Once the immediate danger is addressed and the area is declared safe to work in, professional detection finds exactly where gas is escaping, which is rarely obvious, since gas is invisible and odor can travel along pipes and through walls.
FlowFast connects you with an independent local plumber equipped for gas leak detection. The pro uses a combustible-gas detector to survey piping runs and joints, isolates sections of the system, and applies pressure tests to confirm which segment is losing pressure. Leak detection solution on each joint then marks the precise fitting. This methodical approach avoids tearing open walls blindly and ensures the repair targets the real leak, not a guess.
Warning signs
Signs you need this service
- You smell the rotten-egg odor of mercaptan near piping, appliances, or the meter. Leave and call the utility first.
- A hissing sound comes from a pipe joint or appliance connection even when nothing is running.
- Houseplants die suddenly near a gas line, or you notice dead vegetation patches above a buried line outdoors.
- Your gas bill spikes without increased usage, which can indicate a slow leak somewhere in the system.
What to expect
The process, step by step
The pro confirms the area is safe to work in and that emergency responders have cleared any immediate danger.
They survey all accessible piping, joints, and appliance connections with a combustible-gas detector.
Suspect sections are isolated and pressure-tested to confirm which segment is losing pressure.
Each joint in the leaking section is tested with leak detection solution to mark the exact fitting for repair.
Prevention
How to avoid this problem
- If you smell gas, evacuate immediately and call the gas utility or 911 from outside; never use phones, switches, or flames near a suspected leak.
- Have gas piping inspected periodically, especially older steel lines in damp areas prone to corrosion.
- Keep the area around the gas meter clear and protected from vehicle or equipment damage.
