Gas Leak Smell in Your Friendswood Home? Evacuate, Then Call
If you smell that specific rotten-egg or sulfur odor in your Friendswood home, that is not a coincidence — it is an intentional additive to natural gas (mercaptan) designed to warn you of a leak.
Step 1: Leave the Home Immediately
Get every person and pet out. Do not stop to grab valuables. Do not stop to try to find the leak. Do not open windows on your way out.
Step 2: DO NOT Touch Any Electrical Switch
Do not flip lights on or off. Do not use a phone or garage-door opener inside. Do not start a vehicle inside the garage. Any spark can ignite a gas concentration.
Step 3: Once Outside, Call
From a safe distance, call CenterPoint Energy Gas Emergency at 713-659-2111, then Friendswood Plumbing Co. at (831) 290-4327. Call 911 if you also see fire or smoke.
Step 4: Do Not Re-Enter Until Cleared
Wait outside. Do not let anyone go back in. CenterPoint will tell you when it is safe.
Prevention: Once-Every-5-Years Gas System Check
For homes with older black-iron gas piping, we recommend a professional gas system inspection every 5 years.
What CenterPoint Does When You Report a Gas Leak
When you call CenterPoint's gas emergency line (713-659-2111), a utility technician is dispatched to your address within a target of 45 minutes. Their job is not to fix your leak — it is to secure the situation. They check for the leak source, shut off gas at the meter if warranted, and ventilate the area. Once the immediate danger is cleared, they leave and CenterPoint red-tags the meter. That red tag stays until a licensed plumber (us) locates and repairs the interior leak, passes City of Friendswood inspection, and CenterPoint restores service. The full sequence typically takes 24 to 72 hours from initial leak report to gas restored.
Gas Line Age Is the Real Underlying Question
Most Friendswood gas leaks happen at the same handful of places: an aging black-iron joint that has worked loose over decades, a corroded outdoor union near the meter, or a poorly-installed CSST (yellow flex) connector that was never properly bonded. Any home built before 1990 with original black iron gas piping is worth a professional gas system inspection every 5 to 10 years — a bubble test at every joint, a pressure test of the whole system, and a written report you can hand to your homeowner insurance carrier for a possible discount.
Preventive Gas System Inspection
Call (831) 290-4327 for a preventive gas system inspection at your Friendswood home. Licensed gas plumber, electronic combustible-gas detector, bubble test on visible joints, whole-system pressure test, and a written report. Small investment, catastrophic-risk mitigation.
The Carbon Monoxide Detector Placement Every Gas Home Needs
Beyond gas leak detection, every Friendswood home with gas appliances (water heater, furnace, range, or fireplace) should have working carbon monoxide detectors installed per current code — at minimum, one on every level of the home and one within 10 feet of every sleeping area. CO is odorless and produced when gas combustion is incomplete, most commonly by an aging water heater with a blocked flue or a furnace with a cracked heat exchanger. Battery-powered CO detectors cost $25 to $40 and take 5 minutes to install. Combination smoke/CO units are marginally more expensive and consolidate what would otherwise be two separate wall placements. Test both types monthly and replace batteries at daylight-saving time changes.
When Ventilation, Not Repair, Is Actually the Fix
Some Friendswood homeowners smell what they think is a gas leak and it turns out to be a ventilation issue with a gas appliance rather than an actual gas line leak. A water heater flue with restricted draft can spill combustion gases (including trace mercaptan smells and, more dangerously, carbon monoxide) into the room. A furnace with a cracked heat exchanger can produce similar symptoms. A range hood that isn't venting cooking gas properly can create pockets of unburned methane odor. When a licensed plumber responds to a gas smell call in your Friendswood home, a proper diagnosis includes checking appliance ventilation, not just testing gas lines. If the fix is a $75 draft hood adjustment instead of a $600 line repair, that's the honest answer we deliver.
