MGA Plumbing is the O'Fallon plumbing company to call for gas leak repair. Our local plumbers are available 24/7, arrive on time and fix the problem right the first time. Transparent flat-rate pricing before any work begins.
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.
Because we dispatch from the St. Louis Metro area, a MGA Plumbing plumber can usually reach any address in O'Fallon fast — including St. Louis and St. Charles. For gas leak repair emergencies, that speed is the difference between a simple repair and major water damage.
