If you smell gas: leave immediately, don't flip switches, and call your gas utility and 911 from outside. Once the area is safe, our plumbers locate the leak with electronic detectors and pressure testing, repair or replace the faulty section and verify the whole system holds pressure before restoring service.
We repair black iron, CSST and copper gas lines for furnaces, water heaters, ranges, dryers, fireplaces, grills and generators.
