Frederick is served by Black Hills Energy, so a gas smell means leave the house, call 911, then call Black Hills Energy at the emergency number on your bill. Leaks after the meter, new appliance lines and tankless upgrades are plumber work; call the number on this page to be connected with a local plumber in Frederick.

Signs to watch for
- A rotten-egg odor indoors. Leave before doing anything else.
- A hiss near a gas valve or behind the dryer or range
- Furnace flames that flicker orange instead of burning steady blue
- A water heater pilot that goes out repeatedly
- Sooty marks near a vent or draft hood
Gas lines in Frederick homes
Frederick began as a coal-mining town and is now one of the fastest-growing of the Carbon Valley Tri-Towns along I-25. Most homes are newer family subdivisions, with a smaller core of older houses near the original town center on Locust Street. Newer homes tend to have flexible tubing and a meter sized for the original appliance list. Trouble usually starts when owners add a gas range, a basement fireplace or a tankless water heater years later and the line was never sized for it.
Black Hills Energy is the gas utility here, not Xcel Energy. The Town of Frederick Building Department, at 401 Locust Street, issues permits and handles inspections, either with its own staff or through its private inspection partner. The Town also checks that the plumber listed on a permit holds the required credentials. The page reviewed did not say whether a straight water heater replacement needs a permit, so ask the plumber or the Building Department before the job.
Cost drivers
- Distance from the meter and the route through finished basements or attics
- Whether the existing trunk line needs to be replaced with a larger size
- Number of appliances being added or reconnected
- Bonding for flexible tubing
- Permit and inspection scheduling
What happens on the call
The number on this page connects you with an independent plumber who works on gas piping in Frederick. Be ready to describe the appliance, its BTU rating if you have it, and where it will go. The plumber will explain whether the work needs a Town permit and when the inspection can happen.
If you are not sure how much gas your existing line can carry, the plumber will add up the BTU ratings of every gas appliance in the house and compare that with the pipe size and length from the meter. That calculation is what decides whether a new range or tankless heater can tie into the current system or needs a dedicated line. Ask to see the numbers if you are curious; it is a straightforward check.
