If you smell gas right now, stop reading. Leave the building, take everyone with you, don't flip switches or use your phone inside, and call your gas utility and us from outside. Gas is the one plumbing hazard where the first step is always to get out.
For everything else — a new gas range or dryer hookup, a line for a generator or pool heater, a suspected small leak, or an aging line — our licensed gas line service in King of Prussia handles it safely and to code. Gas work requires proper qualification, pressure testing, and inspection. We do all three, every time, with no shortcuts.

Know the Signs of a Gas Leak
The classic sign is the rotten-egg odorant added to natural gas, but you should also know the sound (hissing), the physical symptoms (headache, dizziness, nausea), and the outdoor signs (dead grass over the line, bubbling in standing water). We walk through all of them in our King of Prussia gas leak safety guide.
When in doubt, treat it as real: get out, then call. We provide 24/7 response for gas emergencies alongside our emergency plumbing service.

Frequently Asked Questions
Leave immediately with everyone in the home. Do not turn lights or switches on or off, do not use your phone inside, and do not light anything. From outside or a neighbor's, call your gas utility's emergency line and call us. Do not go back in until it is declared safe.
Yes. We install gas lines for ranges, dryers, water heaters, fireplaces, generators, pool heaters, and outdoor kitchens — sized correctly for the appliance, pressure-tested, permitted, and inspected.
No. Gas work must be done by properly qualified personnel and, in most cases, permitted and inspected. The risk of an improper connection is fire or carbon monoxide. This is one job to always leave to a licensed pro.
Not every leak is strong enough to smell. Watch for a hissing sound near a line or meter, a higher-than-normal gas bill, a pilot that will not stay lit, or dead grass over a buried line. If you suspect one, leave and call — we test lines to locate even small leaks.
In almost every case, yes. Gas work in this area must be permitted and inspected, and for good reason — an improper connection risks fire or carbon monoxide. We pull the permit, build the line to code, pressure-test it, and coordinate the inspection so it is legal and safe.
