We include Gas Leak Detection in every full home inspection free of charge. This is because we believe this is a critical safety check that should never be skipped. Gas Leak Detection is the process of identifying gas leaks in the home using a handheld combustible gas leak detector. Both natural gas and propane gas are commonly used in homes to power heating systems, water heaters, dryers, stoves, fireplaces, etc. We use a handheld gas leak detector to trace the visible and accessible gas piping within the home, concentrating on unions (connections with in the piping) and any accessible appliance connectors. This can also be used to detect leaks at or near a gas meter.
