Who Should Handle Gas Line Repair on Mercer Island?
Someone certified, working under permit, with the job inspected afterwards. Gas piping is the one part of residential plumbing with no sensible homeowner version, so before anything else, here is what to do if you can smell gas right now.

What Should You Do First If You Smell Gas?
Leave, then call from outside. The order matters more than the speed.
Get out. If you are indoors, leave the building.
Create no spark. No light switches either way, no garage door opener, no doorbell, no matches, no lighters. No phone inside the building either, landline included.
Use a phone outside, well away from the gas.
Call Puget Sound Energy on 1-888-225-5773, staffed 24 hours, or call 911.
Do not go back in to open windows. Do not look for the source. Do not shut anything off if that means going back inside. And if your gas has already been shut off for any reason, do not turn it back on yourself.
Smell is not the only sign. A hissing sound, bubbles rising in standing water, blowing dirt, or dead vegetation over a buried line all point the same way. Natural gas has no smell of its own, so the rotten-egg odour is an additive doing its job.
Our part starts after the utility has made the property safe, never instead of them. Any gas leak repair service Seattle Eastside residents call should say so plainly, rather than offering to attend first.
Which Pipe Is Yours, and Which Is Theirs?
The meter is the dividing line, and it decides who you call and who pays.
Everything from the street to the meter belongs to Puget Sound Energy. They maintain it, they locate it, and a fault on that side is theirs to fix at no cost to you.
Everything after the meter is yours. That covers the runs to your range, furnace, water heater, fireplace, dryer, grill and fire pit, including anything buried out to a garage, shop or outdoor kitchen. Buried metallic pipe corrodes if nobody ever looks at it, and that is the piping we work on.
One consequence surprises almost everyone. Call 811 before you dig and the utility will mark its own lines to the meter for free, but nobody marks your customer-owned piping. That needs a private locator, booked separately, before a spade goes in. If you are planning a patio, a fence, a pond or a raised bed on a property with a buried gas run, that call comes first.
We handle gas line repair Mercer Island WA properties need on that customer side: corroded buried runs, damaged sections, failed fittings, appliance connections, and pressure and sizing problems on systems that have had appliances added over the years.
What Happens When You Call Us?
Four stages, and the first two happen before anyone picks up a tool.
Locate and assess. We establish where the customer-owned piping actually runs, which on an older Mercer Island property is rarely where people assume. Buried runs get a private locate before excavation.
Scope and permit. The work is defined, the permit applied for, and the inspection scheduled. This is the stage cheap quotes skip.
The work itself. Repair or replacement of the affected section, or a new run sized for the appliance load. Gas is isolated for the duration and the system is tested before anything is closed up or turned back on.
Inspection and sign-off. The jurisdiction inspects, and you get the paperwork. That document matters later, at sale or at a claim, more than most people expect.
On a repair we would rather find the cause than patch the symptom. A fitting that failed once is a fitting; a run that has failed twice is usually a corrosion problem with more of it still buried.
Why Does a Blocked Sewer Matter Here?
Because of a hazard that connects two jobs which look entirely unrelated.
Gas lines have, on rare occasions, been installed straight through a sewer line. It is called a cross-bore. Run a drain-clearing cutting head into a blockage at that point and it can strike the gas line, with fire or explosion the result.
So before a blocked sewer is cleared on a property with buried gas, the utility should be called to confirm it is safe. They will usually attend within the hour.
We raise this ourselves on any recurring blockage, because a drain that blocks in the same place every year is exactly the pattern worth checking. Our Mercer Island drain cleaning guide covers how those side sewers are cleared and why the camera goes in before the cable.

What Permits, Inspections and Credentials Apply?
Gas piping is permitted and inspected work, and there is a practical reason beyond compliance: on a new installation, the utility will not set a meter and start service until the local jurisdiction has inspected and approved the piping. Skipping the permit can mean the gas never gets turned on at all.
Requirements vary between King County jurisdictions, so your own city is the authority on fees and timing. Mercer Island handles its own permitting, and our Mercer Island plumber guide covers the other boundary questions on the island.
On credentials, Washington asks for two things rather than one. The company holds a contractor licence registered with Labor & Industries. Separately, the person doing the work holds their own certification and carries photo identification with it. General contractor registration does not authorise gas piping.
Both are free to check on L&I's Verify a Contractor tool, which also shows the bond, the liability insurance and the workers' compensation account. That last one protects you directly if somebody is hurt on your property.

What Does It Cost, and What Can We Install?
How much does gas line repair cost? It turns on where the fault sits, how reachable the pipe is, and what the fix involves. A failed fitting at an accessible appliance connection is a modest job. A corroded buried run needs a private locate, excavation, reinstatement and a permit, and prices accordingly.
How much does it cost to install a gas line? The drivers are distance from the meter, the pipe size the appliance load demands, whether the run is interior or buried, and how much finish work gets disturbed. Sizing is the part homeowners underestimate. Reaching an appliance is easy; delivering enough volume at the right pressure with every appliance running at once is the actual engineering, and it is why adding a range to an old system sometimes means upsizing more than the last few feet.
We install for ranges and cooktops, fireplaces and fire features, dryers, water heaters, outdoor kitchens, grills and fire pits. The gas line installation King County WA homeowners ask for most often is an outdoor kitchen, which nearly always means a buried run, and therefore a locate before digging.
Related work sits on our specialized plumbing page, routine jobs on general plumbing, and urgent water problems with the emergency team. For gas specifically, the utility and 911 come before us. We serve Mercer Island plus Bellevue, Kirkland, Sammamish, Issaquah and Redmond, with the full list on our locations page and finished work in the gallery.
Searching for the best gas line repair plumber near Mercer Island WA, or wondering who repairs gas lines near me and who does permitted gas line work in the Seattle Eastside area? Ask two questions: is this permitted work, and can I see the certification.

Frequently Asked Questions
1. What should I do first if I smell gas?
Leave the building first, before anything else. Do not operate any electrical switch, garage door opener or doorbell, do not light anything, and do not use a phone indoors, landline included. From outside and well clear of the property, call Puget Sound Energy on 1-888-225-5773 or 911. Do not return to open windows or hunt for the source, and if the gas has already been shut off, leave it off until the utility restores it. If neighbours share a wall or a driveway, tell them on your way out.
2. How much does gas line repair cost in the Mercer Island area?
Most repairs fall into two bands. An accessible fault, typically a failed fitting or connection at an appliance, is a short job at the lower end. A buried run that has corroded is the higher band, because it brings a private line locate, excavation, reinstatement of whatever was dug up, and a permit with an inspection. Two things change the figure more than anything else: whether the pipe can be reached without excavation, and whether the fault is isolated or a symptom of a run that is failing along its length.
3. Is a permit and inspection required for gas line work?
Yes. The part worth knowing is the consequence rather than the rule: on new installations the utility will not set a meter and begin service until the jurisdiction has inspected and approved the piping, so unpermitted work can leave you with no gas rather than just a paperwork problem. Keep the signed-off documentation somewhere findable. It gets asked for at sale, and occasionally by an insurer after an unrelated incident, and reproducing it years later is considerably harder than filing it.
4. Are you licensed and certified for gas piping work in Washington?
Yes, and there are two separate things to check on any contractor. The business holds a contractor licence registered with Labor & Industries. The individual doing the work holds a personal certification and should be carrying photo identification with it on site. Registration as a general contractor does not cover gas piping. Look both up free on L&I's Verify a Contractor tool, and while you are there check the workers' compensation account is open, because that is what protects you if someone is injured at your property.
5. Do you install gas lines for ranges, fireplaces, and outdoor grills?
Yes, along with dryers, water heaters, fire features and outdoor kitchens. The question to settle early is capacity rather than distance. Every appliance adds demand, and a system that coped with a furnace and a water heater may not deliver proper pressure once a range and a fire pit join it, which shows up as poor burner performance rather than an obvious fault. We work out the total load first and size the run to it. Outdoor installations almost always involve buried pipe, so a private locate comes before any digging.
