OUR SERVICES
Gas piping is the kind of work you want a licensed plumber doing, not a handyman. Natural gas at residential delivery pressure is safe when the system is tight and properly sized, and dangerous when it isn’t. The margin for error is small. Every job we do is permitted, pressure-tested, and inspected.
We handle gas piping across Sherwood, Tualatin, Tigard, and the rest of Washington County. Common jobs: extending an existing gas line to a new appliance, running a new line for a tankless water heater, replacing old black iron that’s reached end of life, repairing confirmed leaks, and handling the permitting and inspection coordination that gas work requires.

WHAT YOU NEED TO KNOWWhat we do
New gas line installation
Running a new line from the meter or from an existing trunk to feed a new appliance. Common requests in our service area:
Gas line extension
Adding to an existing line when a new appliance is going in near an existing gas source. We assess whether the existing line can handle the added demand, upsize if necessary, and run the new branch.
Gas line replacement
Older Sherwood-area homes often have black iron gas piping running through walls, ceilings, and crawlspaces. Black iron has a long service life but isn’t forever. Corrosion, old joint compound, and failed fittings all eventually need attention. CSST (corrugated stainless steel tubing) is now common for new installs and extensions where flexibility is useful. We work with both.
Gas leak detection and repair
If you smell gas, the first call is to NW Natural (800-882-3377) and evacuation of the house. They handle the emergency shut-off. After the gas is safely off, we’re the ones who find the leak and fix it. Leak repair is typically a joint that has failed, a fitting that has loosened, or a section of pipe that’s corroded through.
Appliance hookup
Connecting a gas appliance to the line with the correct flex connector (if appropriate for the appliance and jurisdiction), shut-off valve, and pressure test. Many appliance warranties require professional installation; we provide the documentation.
OUR PROCESSHow gas piping jobs actually run
Assessment. We look at the existing system and the appliance(s) you’re adding. Measure pipe lengths, check pipe diameters, calculate BTU demand, determine whether the existing capacity supports the new load. Sometimes the bottleneck is the supply line from the meter. You may have an appliance you want, but not enough capacity to feed it without upsizing.
Design and quote. We map the route, size the pipe for the combined demand, and quote the job in writing. Route matters: running through a finished wall costs more than running through an accessible crawlspace.
Permit. Almost all gas work requires a plumbing or mechanical permit in Oregon jurisdictions. We pull the permit as part of the job.
Install. Black iron, CSST, or a combination depending on the run. All joints pipe-dope sealed or tape-wrapped per code. Every section pressure-tested before being put into service.
Inspection. The local jurisdiction (City of Sherwood, Washington County, or applicable municipality) sends an inspector to verify the work. We’re there for the inspection and handle any corrections that come out of it.
Commissioning. Connect the appliance, light pilot if applicable, confirm correct combustion, leave you with documentation.
WARNING SIGNSGas leak warning signs
If any of these are happening in your home, stop what you’re doing:
Evacuate, don’t use light switches or electronics (the spark can ignite gas), don’t start a car in the garage, and call NW Natural’s emergency line at 800-882-3377 from outside. Then call us to find and repair the leak once the gas is safely off.
WHY SHERWOODWhy Sherwood for gas work
Gas work is the category where you most want a licensed plumber who actually understands the system rather than a handyman running a flexible line. The margin for error is small — undersized gas lines starve appliances, oversized risk other code violations, and bad joints leak. We pressure-test every section before it goes into service.
This is also a category where Devin’s tankless specialty matters. Most tankless conversions in our service area need the gas line upsized — the BTU demand on a tankless unit is often higher than the existing tank water heater, and the existing line was sized for the tank, not the tankless. We catch that during the assessment before the unit ships, not after it’s installed and the unit is starving. Solving the problems other shops can’t.

FREQUENTLY ASKED QUESTIONSFrequently asked questions
In nearly every Oregon jurisdiction, yes. Even a seemingly small job like extending a line to a new range is a permitted install. We handle the permit and the inspection.
We don’t quote gas work over the phone. Length, route, whether the existing supply needs upsizing, permit fees, and accessibility all matter — a short run to a kitchen appliance in an open crawlspace is a different job than a long run through finished walls for a new tankless water heater. We come out, measure, calculate the BTU demand, map the route, and give you a written quote before any work starts. Service-call jobs are billed on completion. For larger projects (multi-appliance hookups, full system extensions, or anything that runs longer than a single service-call window) we collect a deposit at the start and work through a milestone pay schedule.
If gas service is available to the house and there’s an existing trunk with capacity, yes. The cost depends on how far the appliance is from the existing gas source and how accessible the route is.
CSST is code-approved and widely used. It does need proper bonding to the home’s electrical grounding system to protect against lightning-induced arcing. That bonding is part of a correct install.
We handle the corrections. Failed inspections on our gas work are rare because we follow the code closely the first time, but if the inspector flags something, we address it and re-inspect.
