Gas Line Services We Provide
Chase handles residential gas line work of all types throughout the Oregon City and Portland metro area. Whether you are running a new line to a gas appliance, repairing a damaged section of pipe, or connecting a gas system to a new home, our team can take it from start to finish.
If your home does not currently have gas service, or you want to extend your existing gas piping to reach a new appliance or a new area of the house, we handle the full installation. That includes mapping the pipeline route, pulling the necessary permits from your local building department, clearing existing utility lines, running approved piping materials, pressure testing the system, and passing final municipal inspections. Every step is accounted for before we leave.
Damaged, corroded, or leaking gas lines need to be addressed immediately. A poorly sealed gas line can release toxic fumes that cause headaches, nausea, or worse. If you have noticed a rotten egg smell, heard a hissing sound near a pipe, or seen physical damage to your gas piping, call us. Do not wait to see if it gets better.
Adding a gas stove, gas range, gas fireplace, water heater, gas dryer, or outdoor gas appliance to your home requires a proper connection point and shutoff valve installation. Chase handles the hookup and tests everything before we leave. If the existing gas piping in your home is not sized correctly to supply the new appliance, we will let you know and make the necessary upgrades.
Running gas to a backyard fire pit, outdoor kitchen, patio heater, or generator requires its own set of considerations, including proper burial depth, approved materials for outdoor and underground use, and coordination with NW Natural if a new gas meter connection is involved. We handle outdoor gas line installation throughout Clackamas County and the greater Portland area.
Natural gas powers some of the most reliable and cost-effective appliances in a home. If you are considering switching from electric to gas, or adding any of the following, a properly sized and installed gas line is required:
Furnaces and forced-air heating systems
Gas water heaters
Gas stoves and ranges
Gas ovens
Gas fireplaces and fireplace inserts
Gas clothes dryers
Outdoor grills and fire pits
Whole-home generators
Each appliance has a specific BTU requirement, and the total gas load of all appliances in the home must be calculated to determine the correct pipe diameter. An undersized line will starve appliances of pressure, leading to poor performance or equipment damage over time. Our technicians size every installation correctly for the full load of your home.
Why Gas Line Work Requires a Licensed Professional
In Oregon, it is illegal for unlicensed individuals to perform gas line work. Even minor gas piping modifications must be inspected by local building inspectors after completion. Homeowners who attempt to install their own gas lines risk fines, failed inspections, and liability exposure. Most home insurance policies do not cover damages resulting from unlicensed gas work, which means a leak caused by a DIY repair could leave you without coverage.
Natural gas is unforgiving when something goes wrong. Improper fittings, incorrectly sized pipe, or a bad seal can cause slow leaks that go undetected for weeks, exposing your family to toxic fumes or worse.
Chase is a licensed contractor with full liability insurance. Our work complies with Oregon and local building codes. When we pull a permit and schedule an inspection, you have a paper trail that protects your home's value and your family's safety.
What Goes Into a Gas Line Installation
Step 1: Planning and Permits
Before any pipe is run, we map the route, calculate the gas load for all connected appliances, and pull the required permits from your local building department. If digging is involved for any outdoor gas lines, we contact the Oregon Utility Notification Center to mark underground utility lines before breaking ground.
Step 2: Choosing the Right Materials
The two most common materials for residential gas piping are black iron pipe and corrugated stainless steel tubing (CSST). Black iron pipe is the long-established standard — it is strong, durable, and widely recognized by code. CSST is flexible and easier to route through walls and around obstacles, but its use is governed by local codes that vary by jurisdiction.
One important note: thread seal tape, sometimes called Teflon tape, is not recommended for steel gas pipe fittings. It does not seal threaded steel joints reliably and increases leak risk. We use pipe thread sealant compounds rated specifically for gas connections.
Step 3: Running the Pipe
We run the gas piping along the mapped route, connecting to the main line and working outward to each appliance connection point. Every joint is made for a tight fit, and no connections are left to chance.
Step 4: Shutoff Valves and Sediment Traps
A shutoff valve must be installed near each gas appliance — within 3 feet, per code — so the gas supply to that appliance can be isolated quickly for maintenance or in an emergency. These valves need to be easily accessible. We also install a sediment trap, sometimes called a dirt pocket, on the line feeding each appliance. The trap catches water, debris, and pipe scale before they can enter the appliance and cause damage. It sits downstream of the shutoff valve so it can be serviced independently if needed.
Step 5: Pressure Testing
Before the system is activated, we pressure test the entire gas piping installation. Professionals conduct pressure testing for a minimum of 24 hours to confirm there are no leaks anywhere in the system. If anything fails, it is repaired and retested before gas is ever introduced to the line.
Step 6: Inspection and Activation
Once the installation passes pressure testing, we schedule the required inspection with the local building department. The inspector verifies that the work meets Oregon building codes and local requirements. After the inspection is passed, we activate the system, relight appliances, and confirm everything is operating correctly before we leave.
Signs You May Have a Gas Line Problem
Gas leaks do not always announce themselves dramatically. Here are the signs Oregon City homeowners should know:
A rotten egg or sulfur smell near an appliance, pipe, or gas meter
A hissing or whistling sound near a gas line or connection
Dead or dying vegetation in a specific area of the yard, which can indicate an underground leak
Higher than normal gas bills without a change in usage
Appliances that pilot out frequently or have weak, inconsistent flames
Physical rust, corrosion, or visible damage on exposed piping
If you notice any of these, leave the home, avoid using any electrical switches, and call your gas company from outside. Once the gas company has confirmed the line is safe, call Chase and we will inspect the piping and make the necessary repairs.
The process is straightforward. Call us or request service online and we will get you scheduled for an estimate or a service visit. When we arrive, we assess the existing gas system, confirm what work is needed, and give you a clear picture of scope and cost before anything starts. No surprises.
For new gas line installation, we handle permits and coordinate with NW Natural if a new meter connection is required. We serve Oregon City, Clackamas, Happy Valley, Milwaukie, Gladstone, West Linn, Lake Oswego, Canby, and the broader Portland metro area. If you are in Clackamas County or east Portland and need gas piping done right, give us a call.
Frequently Asked Questions
Is it legal to install my own gas line in Oregon?
In most cases, no. Oregon requires that gas line work be performed by a licensed contractor, and virtually all gas line installations must be permitted and inspected by local building inspectors. Homeowners who attempt unlicensed gas work risk fines, failed home sales, voided insurance coverage, and serious safety liability. Hire a licensed professional.
What does gas line installation cost in Oregon City?
Cost depends on the scope of the job. Simple runs to a single appliance in an accessible location are generally less expensive. Longer runs, outdoor lines that require trenching, or installations that involve coordinating a new gas meter with NW Natural will cost more. Chase provides a clear estimate before any work starts so you know exactly what you are agreeing to.
How long does gas line installation take?
Most residential gas line installations are completed in a single day. More complex projects involving multiple appliance connections, outdoor lines, or new gas service from the street may take two to three days, including time to schedule and pass the required inspection.
What is CSST and when is it used?
CSST stands for corrugated stainless steel tubing. It is a flexible alternative to black iron pipe that is easier to route through walls and around obstacles. Both materials are code-approved in most jurisdictions, though local codes vary on where and how each can be used. Our technicians will specify the right material for your project based on your home's layout and local requirements.
What is a sediment trap and do I need one?
A sediment trap is a short section of capped pipe installed in the gas line just before each appliance. It creates a pocket where debris, moisture, and pipe scale can collect instead of entering the appliance. Oregon code requires sediment traps on furnaces and other gas equipment. We install them as a standard part of every appliance connection.
Do I need a shutoff valve for each gas appliance?
Yes. Code requires a shutoff valve within 3 feet of each gas appliance so the gas supply can be cut to that specific appliance for service or in an emergency. Every appliance connection Chase installs includes a properly positioned shutoff valve.
Can Chase run a gas line to my outdoor grill or fire pit?
Yes. We install outdoor gas lines throughout Clackamas County and the Portland area. Outdoor installations require specific materials rated for underground or exterior use, proper burial depth, and in some cases coordination with NW Natural. We handle all of it.
What is the difference between natural gas and propane?
Natural gas is delivered through the utility's pipeline directly to your home via the gas meter. Propane is stored in a tank on your property and delivered by truck. Chase works with both. If your home runs on propane and you are considering converting to natural gas, or vice versa, talk to us about what that conversion involves for your gas piping system.
What should I do if I smell gas?
Leave the home immediately. Do not turn lights on or off, do not use your phone until you are outside, and do not try to find the source of the leak yourself. Call your gas company from outside or from a neighbor's home. Once they have cleared the line, contact Chase and we will inspect the gas piping and make any needed repairs before the system is reactivated.
Does Chase handle the permits?
Yes. We pull all required permits and coordinate inspections as part of the job. You do not need to navigate the building department on your own.
