Most local jurisdictions require permits for gas line modifications, including capping, with fees ranging from $25 to $100. These permits ensure the work meets safety codes and building regulations. Your professional plumber often handles the permit application process as part of their service. Skipping required permits can result in penalties during home inspections or when selling your property.
Full gas line removal with capping at the source costs an average of $250, approximately double the price of simple capping. This more comprehensive service involves disconnecting the entire pipe run, removing it from the premises, and properly sealing the supply point. The higher cost reflects the additional labor time of one to two hours and the complexity involved in the complete removal process.
A professional completes a standard gas line capping in 30 to 60 minutes when the pipe is readily accessible. The process involves shutting off the gas supply, releasing any remaining gas in the line, applying the appropriate cap with sealing materials, and conducting safety tests. More complex situations requiring wall access or complete line removal may extend the job to one to two hours, with costs approaching $250 for the more extensive work.
