Direct answer

What do you do if you smell gas?

Leave immediately -- do not flip light switches, use your phone inside the home, or stop to grab belongings, since a single spark can ignite an explosive gas atmosphere. Once outside and clear of the building, call 911 and your gas utility -- Puget Sound Energy in the Bothell area, at 1-888-225-5773, available 24 hours -- and do not reenter until the utility has shut off the meter and confirmed the building is safe. Only after that clearance should you call Pine Rooter to locate and repair the leak; we use electronic gas detectors and pressure testing to find the exact failure point, make the repair, and pressure test the repaired section before documenting the work.

Why choose Pine Rooter

Why Bothell homeowners choose Pine Rooter for gas line services

Licensed for gas work in Washington State

Gas line work in Washington State requires a plumber licensed for gas piping. We carry the correct licensing and insurance for both natural gas and propane systems. Unlicensed gas work voids homeowner's insurance coverage for any resulting damage and creates legal liability that attaches to the property, not just the person who did the work.

Emergency response for gas leaks

We prioritize gas leak calls. After the utility has shut off service and confirmed safe reentry, we dispatch as quickly as possible to locate and repair the leak. Getting gas service restored quickly -- correctly -- matters, especially in winter when a home without heat becomes a secondary emergency.

Experience with natural gas and propane systems

Natural gas and propane require different fitting materials, different pressure ratings, and different connector specifications. We work with both systems across the Bothell area, including Eastside neighborhoods where propane serves properties outside Puget Sound Energy's natural gas distribution footprint.

Pressure tested after every repair or installation

We do not connect appliances and restore service without a documented pressure test on the affected section. The pressure test is the only way to confirm with certainty that a gas repair is complete. A visual inspection of fittings is not sufficient. Every job is pressure tested before it is closed out.

Written documentation for permit and insurance

Every gas line job gets written documentation: what was done, what materials were used, and what the pressure test results showed. This matters when you sell the home, file an insurance claim, or a future technician needs to understand the history of the gas system. Gas work without a paper trail creates problems years down the road.

Signs you need this

Warning signs of a gas line problem

Rotten egg or sulfur smell anywhere in the home -- natural gas is odorized with mercaptan for detection
Hissing sound near a gas appliance, line, or fitting -- indicates pressurized gas escaping
Dead or dying vegetation in a line directly above where a buried gas line runs in the yard
Gas appliance not igniting reliably when it previously lit without issue
Yellow or orange flame instead of blue on a gas burner -- indicates incomplete combustion
Recent physical impact or damage to a gas line connection or appliance

What not to do

Actions to avoid if you suspect a gas leak

Do not flip any light switches on or off -- the electrical arc from a switch can ignite accumulated gas.
Do not use your phone inside the building -- make calls from outside once you have evacuated.
Do not open windows to try to air out the space before evacuating -- get out first, ventilate later after the utility clears reentry.
Do not try to locate the leak yourself by running a flame near fittings -- this is extremely dangerous and never appropriate.
Do not turn the gas back on yourself after it has been shut off for a suspected leak -- restoration requires utility sign-off and a pressure test by a licensed technician.
Do not use soapy water to check connections on active gas lines unless the utility has confirmed the line is at safe operating pressure and there is no active leak in the area.

Not sure what you need?

Match your situation to the right service

Not every gas-adjacent problem is a gas line issue. Here is a quick way to tell which service actually solves what you are dealing with.

Gas smell, hissing fitting, or a new BBQ hookup

Leak detection, repair, and new gas line installation for appliances and outdoor connections are exactly what this service covers.

This service handles it

Gas leak combined with water damage or flooding

If a gas failure also caused water damage -- from an appliance connection or during the emergency shutoff -- emergency plumbing coordinates both repairs at once.

See Emergency Plumbing

Gas water heater not igniting or heating inconsistently

When the problem is specific to a gas water heater rather than the supply line itself, water heater repair evaluates both the appliance and its gas connection.

See Water Heater Repair

Planning a tankless water heater upgrade

Tankless units need a gas line sized for a much higher BTU load -- our tankless installation service and gas line sizing work together on this project.

Emergency vs. scheduled compared

Gas emergencies versus scheduled gas line work

A gas smell anywhere in the home is an emergency that requires immediate action -- evacuate, call 911 and the utility, do not wait to see if it gets better. A gas smell at an appliance connection when the appliance is in use can indicate a leak at the flex connector that warrants same-day service even if it is not strong enough to require evacuation.

Scheduled gas line work covers a broad range of non-emergency jobs: running a new gas line to a kitchen island for a range, adding a BBQ connection to the patio, connecting a new gas dryer, or replacing aging flex connectors as a preventive measure. These jobs are planned, permitted where required, and scheduled at a time that works for the homeowner.

A third category is proactive inspection. If your home has original gas piping from the 1960s or 1970s, a pressure test and visual inspection can identify corroded fittings, aging connectors, and line sections approaching end of life before they become an emergency -- far less disruptive than an emergency repair after a connector fails.

How the job runs

How gas line work gets done safely

Every gas line job follows a strict sequence. Safety assessment comes first and work does not begin until the gas supply is confirmed off. The final pressure test happens before any appliance is reconnected.

Safety assessment and gas shutoff confirmation

Before any tools come out, we confirm the gas supply is off at the appropriate shutoff -- appliance valve, branch shutoff, or meter. We use an electronic gas detector to verify no residual gas is present in the work area. Work does not begin until the environment is confirmed safe.

Pressure test to locate or confirm the problem

For leak detection, we isolate the affected section and apply test pressure to confirm and locate the leak. For new installations, we test the existing system before tying in to confirm the starting point is sound. Pressure testing before work eliminates surprises after the work is done.

Repair or new line installation

Repairs are made using code-compliant materials -- corroded fittings cut out and replaced, flex connectors swapped for new code-rated connectors, cracked pipe sections replaced. New lines are run in the correct pipe material for the location, sized for the appliance BTU load, supported at code-required intervals, and fitted with shutoff valves at each appliance connection.

Pressure test after all work is complete

Every repaired or newly installed section is pressure tested at operating pressure before any appliance is reconnected or the meter is reopened. We hold the test pressure for a full monitoring period and confirm there is no pressure drop before proceeding. This test is not skipped or abbreviated.

Appliance reconnection and ignition check

After the pressure test passes, appliances are reconnected, the gas supply is restored, and each appliance is operated to confirm correct ignition and flame character. A natural gas burner should produce a steady blue flame. Yellow or orange flame indicates incomplete combustion and requires further investigation before the appliance is left in service.

Written documentation

We provide written documentation of the work performed, the pressure test results, and the materials used. This record is important for your insurance company, for any future inspections, and for the utility if service was interrupted. Gas line work without documentation creates a gap in the record of your home's systems.

Local conditions & guidance

Bothell gas service and Puget Sound Energy

Bothell is served by Puget Sound Energy for natural gas distribution. Many Bothell neighborhoods were converted from oil heat to natural gas in the 1980s and 1990s, leaving behind original black iron pipe and first-generation corrugated stainless steel tubing (CSST) that has now been in service for thirty to forty years. Black iron connections develop corrosion at threaded joints over time, and older CSST without proper bonding can be vulnerable to lightning-induced pinhole arcing -- homes of this era are good candidates for a proactive gas line inspection. Newer Bothell neighborhoods on the Eastside and in suburban growth areas sometimes fall outside PSE's natural gas footprint and rely on propane delivered by tank, which uses different regulator pressures and requires appliances configured specifically for propane rather than natural gas.

Code and licensing guidance: Gas line work in Washington State must be performed by a plumber or gas fitter holding the appropriate state license, and new gas line installations, extensions, and most significant repairs require a permit and inspection -- like-for-like flex connector replacement at an existing appliance is a common exception. Never connect a natural-gas-configured appliance to a propane supply or vice versa without a proper conversion kit, since mismatched fuel and appliance configuration can produce dangerous carbon monoxide levels. Gas work performed without required permits or by an unlicensed party can void homeowner's insurance coverage and create issues when the home is later sold.

FAQ

Gas line questions Bothell homeowners ask

In most cases, yes. Washington State and the City of Bothell require permits for new gas line installations, gas line extensions, and significant repairs. Like-for-like appliance connector replacement -- swapping an old flex connector for a new one at an existing appliance connection -- typically does not require a permit. We assess the permit requirement for every gas line job and handle the application when a permit is needed. Gas work done without required permits creates issues when selling the home and may void insurance coverage for related damage.

Yes. Outdoor gas line installations for BBQ grills, patio heaters, and fire tables are a common request in Bothell. The work involves running a gas line from the existing distribution point inside the home -- usually the basement or utility room -- through the exterior wall or under the slab to a shutoff valve at the outdoor connection point. Outdoor lines must be run in approved materials rated for burial or exterior exposure, and the connection requires a dedicated shutoff valve accessible near the appliance. We permit and pressure test every outdoor gas installation.

CSST stands for corrugated stainless steel tubing -- a flexible yellow-jacketed gas line material that became widely used in the 1990s. Early-generation CSST without arc-rated jacketing can be vulnerable to lightning-induced electrical arcing that creates pinhole perforations in the tubing wall. Current code in most jurisdictions, including Washington State, requires bonding of CSST at specific intervals to reduce this risk. If your home has CSST that was installed before current bonding requirements and has not been inspected or upgraded, a bonding evaluation is worth scheduling. Not all CSST is a problem -- properly bonded arc-rated CSST is a safe and code-compliant product.

Appliance flex connectors -- the short corrugated metal hose that connects the gas shutoff valve to the appliance -- should be replaced if they are more than ten years old, show any signs of corrosion or physical damage, or are made of uncoated brass (the older gold-colored connectors that are no longer code-compliant in most jurisdictions). If you have never replaced the flex connector behind your range or dryer and the appliances have been in place for over a decade, replacement is a straightforward preventive measure. We replace flex connectors at appliance installation calls and can also schedule a standalone connector inspection and replacement visit.

Natural gas and propane are both delivered through gas lines, but they operate at different pressures, have different BTU content per cubic foot, and require different appliance configurations. Natural gas appliances are not directly compatible with propane without a conversion kit, and vice versa. The regulator that controls pressure at the meter or tank is different for each fuel. When we service a propane system, we account for these differences in pressure settings, fitting materials, and appliance compatibility. Never connect a natural-gas-configured appliance to a propane supply or vice versa -- the appliance will either fail to operate correctly or produce dangerous levels of carbon monoxide.
