Know the warning signs
Signs Your Gas Line
Needs Attention
The smell of gas
Treat any gas odor as an emergency. Follow the safety steps above first, then call Romero Bros once your gas utility says the area is safe.
Hissing near gas piping
A hissing or whistling sound near gas piping or a meter can indicate escaping gas. Leave and call your gas utility or 911.
Damaged, corroded, or exposed piping
Visible corrosion, damage, or piping that has been disturbed should be inspected by a licensed plumber.
Piping disturbed by other work
Digging, construction, or settling near a gas line can disturb it. Have the area checked if you are unsure.
Dead patches near a buried line
A dead or discolored patch of vegetation near where a gas line runs can be a sign worth reporting to your gas utility.
Aging gas piping
Older piping can wear out. An inspection helps show whether it is still in good condition or should be repaired or replaced.

Your options
Repair Or Replace?
It Starts With An Inspection.
When Repair May Make Sense
Some gas line problems are limited to one section or connection. Whether a repair is appropriate depends on what an inspection finds and on the condition of the rest of the piping.
When Replacement May Be Recommended
Replacement may be recommended when a line is leaking, damaged, corroded, or worn out. In our main gas line project, the damaged section was removed and a new line installed.
Gas line work involves safety and applicable code requirements. Romero Bros bases recommendations on inspecting your actual piping and will explain your options so you can decide.

Customer reviews
What Our Customers Say
βRomero Bros showed up the same day to check out my job and give me an estimate. They were cheaper and faster than the other company I had been talking to. They were back the next morning and got everything, and more, repaired. Vicente went the extra mile and covered a few other small things while they were there. I will definitely be using them and Vicente for my future needs!β
