—Vicki. | Colorado HomeownerWe had a gas leak on a Sunday morning. Cooper came out very quickly and diagnosed the gas leak right away. Our gas was turned off immediately and then someone else came out a few hours later and explained what needed to be done and scheduled us for a repair a few days later. The technicians were all very reliable, and professional and knew exactly what the problem was and how it could be fixed. I was really impressed because having a gas leak is a huge safety issue. I am grateful that I called Cooper Heating and Plumbing, these people really care and are very knowledgeable. I am grateful this company is in business and I highly recommend them. Arnold, John, and Brendan were amazing, we appreciate your fast response and knowledge.

Gas lines are sized to code based on what's being used in the home. The farther your gas appliances are from the main supply, the more time, labor, and material the job takes — so longer runs cost more.
A single gas line can support multiple appliances, but each added appliance needs its own hookups and shut-off valves, which increases the cost.
Costs vary with the scope of work and permitting. Underground gas line installations require piping that meets specific standards and generally cost more than above-ground work. Cooper pulls all the permits for you, so that's one less thing to worry about.
The most common signs are a rotten-egg or sulfur smell (an odorant added to natural gas), a hissing or whistling sound near a line or appliance, bubbling in standing water, dead or dying plants near a buried line, an unusually high gas bill, or pilot lights that won't stay lit. Physical symptoms like headaches, dizziness, or nausea can also point to a leak. If you suspect a gas leak, leave the home right away, don't touch light switches or anything that could spark, and call 911 or your gas utility from outside — then call a licensed plumber.
No. Gas line work is dangerous and, in Colorado, must be done by a licensed plumber with a permit and inspection. A small mistake can lead to a leak, fire, explosion, or carbon monoxide exposure. Always hire a licensed, insured professional for any gas line installation, repair, or extension.
Gas piping should be replaced when it's corroded or rusted, leaking, made of outdated or non-code materials, or too small to safely supply the appliances connected to it. Older black iron pipe showing rust, repeated leaks, or a failed inspection are all signs it's time. A licensed plumber can inspect your lines and tell you whether repair or replacement makes more sense.
Yes. Gas lines can be extended or added for a new range, dryer, water heater, fireplace, outdoor grill, pool heater, or backup generator. The existing line has to be sized to code to handle the added demand, and it may need to be upsized. A licensed plumber will confirm capacity, run the new line, and pull the required permit.
Yes. Gas line installation, replacement, and most modifications require a permit and a code inspection in Colorado. This protects your home and keeps the work compliant. Cooper handles all permits and inspections for you.
There's no single price — cost depends on the distance from the gas supply, the number of appliances, whether the line runs above or below ground, and permitting. That's why we offer free in-home estimates with upfront, down-to-the-penny pricing before any work begins.
