Service overview
What Gas Line Installation in Lakewood CO Actually Involves
A gas line carries natural gas from the meter to an appliance — and the work is governed by sizing, materials, permits, and testing, in that order.
Most Lakewood homes heat with gas, and the gas system in a mid-century home was sized for the appliances of its era: a furnace, a tank water heater, and a range. Add a tankless water heater, a gas dryer, a fireplace, or an outdoor kitchen, and the line that was adequate in 1965 may not carry the new load — especially at Lakewood's altitude, where derating of about 4% per 1,000 feet above 2,000 feet trims every gas appliance's output. The first step is always a load calculation: what the meter can supply, what the existing line can carry, and what the new appliance demands. Our tankless water heater installation page explains why that check matters most for tankless units, which draw far more gas at full fire than a tank heater.
The pipe itself is usually steel or corrugated stainless steel tubing, and the choice depends on the run, the access, and the code. Every joint is tested, every line is pressure-tested before use, and the work is permitted through the City of Lakewood and inspected at final — the 2021 International Fuel Gas Code applies alongside the 2021 International Plumbing Code adopted by Lakewood. What gas work is not is a do-it-yourself job: no homeowner install guidance belongs on this page, because the permit, the sizing, and the testing are the job. And the safety rule bears repeating: if you smell gas or hear hissing near a line, leave the property, call 911 or Xcel Energy from outside, and only then call us at (720) 909-6690.
- Leave first for a suspected leak — Smell gas or hear hissing: leave, call 911 or Xcel Energy from outside, then call us.
- Load calculation first — The meter, the existing line, and the new appliance's demand are checked before any pipe is run.
- Altitude derating — About 4% per 1,000 feet above 2,000 feet trims gas appliance output at Lakewood's elevation.
- Permit required — Gas piping needs a City of Lakewood permit — confirm the valuation-based fee with the Permit Counter.
- Pressure-tested — Every line is pressure-tested before it is used, as part of the inspection.
- Aging steel lines — Mid-century steel gas pipe and old fittings are the most common replacement candidates.
- No DIY gas work — Sizing, permits, and testing are the job — this page gives no homeowner install guidance.
The service timeline
How a Gas Line Install Runs
Safety Check First
If the call is a suspected leak, the instruction is to leave and call 911 or Xcel Energy from outside. We do not diagnose a gas smell over the phone.
Load Calculation
We check what the meter can supply, what the existing line can carry, and what the new appliance demands — at Lakewood's altitude.
Route and Material Plan
The run is planned for the shortest safe route with proper support, and the pipe material is chosen for the run and the code.
Permit
The City of Lakewood permit is arranged before work starts. Permit fees are valuation-based — confirm with the Permit Counter at 303-987-7500.
Install, Test, Inspect
The line is installed, pressure-tested, and inspected at final before the appliance is connected and fired.
Tools and methods01 02 03 04 05 06
Tools and Methods We Use
Load Calculations
The meter, the line, and the appliance demand — checked together, at altitude, before any pipe is run.
Pressure Testing — tools and methods
Proves the line holds before it is used, and the test is part of the permit inspection.
Gas Leak Detection
Electronic detection and bubble testing at every joint after install, and for tracing a suspected leak once the property is safe.
Pipe Threading and Fitting
For steel runs, where the house and the run call for it.
Corrugated Stainless Tubing
For runs where flexibility and fewer joints suit the route and the code.
Locating Equipment
Marks buried utilities before any exterior gas line work begins.
Where this service helps
When Lakewood Homeowners Need a Gas Line
A Green Mountain home adds a gas range to a kitchen that was electric.
The existing line serves the furnace and water heater only. A new dedicated line is run from the meter, the load is recalculated, and the range is connected after the pressure test and inspection.
A Carmody split-level converts to a tankless water heater.
The tankless unit draws far more gas at full fire than the tank it replaces. The gas line is upsized and the meter is checked before the heater is installed.
A 1950s Eiber home has aging steel gas pipe with old fittings.
The line is corroded at the fittings and the run is due for replacement. The new line is installed, tested, and inspected, and the old steel is removed.

How Gas Line Work Runs in Lakewood
Lakewood's gas story is a mid-century one: most homes heat with gas, the gas systems were sized for the appliances of the 1950s-70s, and every new gas appliance since has added load to lines that were never recalculated. Aging steel pipe and old fittings in those homes are the most common replacement candidates, and the 2021 International Fuel Gas Code governs the work alongside the plumbing code.
Eiber
1950s homes with aging steel gas pipe and old fittings — the most common replacement candidates.
Daniels Gardens
1940s smaller-lot homes where the gas system was sized for a furnace and a tank heater only.
Carmody
1970s split-levels where a tankless conversion is the usual reason a gas line gets upsized.
Green Mountain
Larger homes adding gas ranges, fireplaces, and outdoor kitchens to lines sized decades ago.
Applewood
1960s ranches where a new gas dryer or range is the first added load in sixty years.
Gas-heavy housing
Most Lakewood homes heat with gas, so the load question comes up on nearly every gas job.
Altitude derating
About 4% per 1,000 feet above 2,000 feet trims every gas appliance's output.
Aging steel pipe
Mid-century steel gas lines and old fittings corrode and loosen over decades.
Tankless demand
A tankless water heater's full-fire draw is the largest single load a home gas line will see.
Before and after
What a Successful Gas Line Install Changes
A new range, properly supplied
Before
Before: a kitchen was electric, and the gas line at the house serves the furnace and water heater only.
After
After: a dedicated line is run from the meter, the load is recalculated, and the range is connected after the pressure test and inspection.
Maintenance: The meter capacity is the limit — a line cannot carry more than the meter supplies, and the calculation comes first.
A tankless conversion, fed properly
Before
Before: a tankless unit is planned, but the existing gas line cannot carry its full-fire draw.
After
After: the line is upsized, the meter is checked, and the heater fires at full output without starving the furnace.
Maintenance: A tankless unit on an undersized line underperforms in February, when every gas appliance is working hardest.
An aging line, replaced
Before
Before: a 1950s steel gas line is corroded at the fittings and the run is due for replacement.
After
After: the new line is installed, tested, and inspected, and the old steel is removed.
Maintenance: Old fittings are the weak point — the replacement covers the run, not just the visible section.
Problems we solve
Gas Line Problems We Solve
Gas work is two kinds of problem: new capacity, and old pipe. The safety problem — a suspected leak — is different from both, and it comes first.
A new gas appliance needs a line
A range, dryer, fireplace, or outdoor kitchen needs a dedicated line sized to its demand, run from the meter and tested.
A tankless heater needs more gas
A tankless unit's full-fire draw exceeds what a tank heater's line carries. The line is upsized and the meter is checked.
Aging steel lines
Mid-century steel gas pipe and old fittings corrode over decades. Replacement is the answer when the fittings are the weak point.
A line that cannot carry the load
Added appliances without a load calculation starve the furnace or the heater. The calculation comes first, and the line follows it.
A suspected gas leak
Smell gas or hear hissing: leave the property, call 911 or Xcel Energy from outside, then call us. This is not a wait-and-see problem.

What We Bring to Your Lakewood Home
Gas work is the most permit- and test-heavy work we do, and the discipline is the point: the load calculation before, the pressure test during, and the inspection after.
- Safety first, always: a suspected leak means leaving the property and calling 911 or Xcel Energy from outside — before any plumbing call.
- Load calculations at Lakewood's altitude, where derating of about 4% per 1,000 feet above 2,000 feet trims appliance output.
- Pressure testing on every line before use, as part of the permit inspection.
- Permit process knowledge: gas piping needs a City of Lakewood permit, with valuation-based fees confirmed at the Permit Counter, 303-987-7500.
- Material choice by run and code — steel or corrugated stainless tubing, not a default.

Homeowners across Lakewood call us when a main line fails, a water heater quits, or a drain will not clear — and the reviews describe the same things we aim for on every visit: a clear explanation of what is wrong, the options before work starts, and a clean job site when we leave. Call (720) 909-6690 — open 24 hours, every day — to talk through what is happening at your home.
What should I do if I smell gas in my home?
Leave the property immediately and call 911 or Xcel Energy from outside. Do not use light switches, phones, or appliances inside the house. Once you are outside and have called for help, call us at (720) 909-6690.
Do I need a permit for a gas line in Lakewood?
Yes. Gas piping needs a City of Lakewood permit. Permit fees are valuation-based, so confirm the fee with the Lakewood Permit Counter at 303-987-7500.
Can my existing gas line handle a tankless water heater?
Often not without changes. A tankless unit draws far more gas at full fire than a tank heater, so the line and the meter must be checked. If the line cannot carry the draw, it is extended or upsized as part of the job.
Do you work on propane lines in Lakewood?
No. Lakewood homes run on natural gas, and propane is a negligible share of the city's housing. This page covers natural gas lines only.
