How Do I Know if I Have a Gas Leak?

Common signs include a sulfur or rotten egg smell, hissing sounds near gas lines, or unexplained physical symptoms like dizziness. Dead plants or bubbling water outdoors can also signal a leak. If you suspect one, evacuate immediately and call for professional help.

Is Gas Leak Detection Safe to Perform in an Occupied Home?

Yes, licensed plumbers use non-invasive tools designed for safe leak detection in homes. Most methods, like electronic sensors or pressure testing, don’t require any demolition. Safety is always our top priority during inspections.

Can You Detect Leaks Under Concrete or in Walls?

Absolutely. We use electronic leak detection equipment that identifies gas concentration levels even beneath slabs or behind drywall. This allows us to locate leaks with minimal disruption to your home.

Do I Need to Leave My Home During Gas Leak Testing?

In most cases, you can stay home during testing, especially if the leak is minor. If the leak is severe or dangerous, we may advise temporary evacuation for your safety. We’ll always guide you through the safest course of action.

Don’t Mess Around With Gas Leaks. Here’s How to Know When to Call Us

Gas leaks demand urgent attention, and Olympic Plumbing Technology is here to help Olympia-area homeowners stay safe. If you notice any of these signs, don’t wait to get professional help:

Rotten egg smell: A strong sulfur-like odor indoors or outdoors is a classic indicator of a leak.
Hissing sounds: Gas escaping from pipes or appliances often makes a soft but telling noise.
Dead patches in grass: Leaking underground lines can kill vegetation or create discolored areas in your yard.
Bubbling in water: Unexplained bubbles in puddles or wet spots could mean gas is escaping below the surface.
Physical symptoms: Dizziness, nausea, or headaches indoors may point to long-term gas exposure.
Higher gas bills: A sudden spike in usage without added appliances often signals a hidden issue.

What Our Customers Say About Us

I had a severely clogged kitchen sink drain that I had tried everything myself to unclog. Finally called in the big guns at Olympic Plumbing. They sent us Technician Steven Shoopman and he went way above and beyond to make certain we have a long lasting, trouble free drain. He ran the camera down several times afterwards to ensure he got a good fix. When he spotted remaining grease pockets he didn't call it good enough, he kept at it until it was fully cleared. I was extremely impressed by his tenacity and professionalism. Definitely got our money's worth....thank you Steven, well done!!

Rafael is an excellent plumber. Honest, knowledgeable, helpful and great communicator. Addressed an outdoor backyard spigot issue quickly and carefully. The replacement spigot system is better and more modern than the original that came with the house.

I had Robby J. come out and take a look at my spare bathroom valves and we had some issues finding a replacement valve at first but we did find one. Since I have an older home it’s been difficult repairing/replacing certain things which has been incredibly frustrating. But Robby was a big help on walking me through everything and even provided me with some financing options to lessen the blow which makes me incredibly happy that I have options. Thank you again for really helping me figure out my next steps and what options would guarantee a long-term solution. I appreciate your time and what you do for the community.

Great job along with being patient and working with me to answer any questions I had! Highly recommend! Follow-Up 18 May 2026: First off, every employee has been kind and courteous. This actual physical installation of the system is great, the plumbing is clean and tidy and looks great. The problem is the system. It really hasn’t worked, or at least hasn’t worked like I expected. I get a maximum of 100 gallons of water before iron starts to appear in the water again. When I got the work done I was given three options, so I the middle priced option that was presented as a “good” option, but not then “best” or “Peace of Mind” as Olympic put it. Anyway, I had a tech come back out and they checked the controller setting and nothing seemed out of order. I am still having them problem, and yesterday 17 May, the system only gave me 60 gallons of water before iron/color came back into my water. I have another appointment today 18 May, and will continue to post updates. No one ever told me what kind of Iron is in my water, but I think the “Good” system option would still give me enough water to have hundreds of gallons. Right I have to regen every day, maybe twice because if our water needs. I hope they can come up with a solution.

Once he got to my home he apologized for the time it took to get back to me. He went straight to work. He had to snake out the sink three times. Finally got it cleared. He gave me suggestions to make clearing clogs better next time He was very polite and professional.
