Denver's Gas Line and Plumbing Specialists — One Family, Full Scope

Specialization

Gas Line Installation & Repair

Gas lines require a master plumber — not a generalist. Jim Unger has been installing and repairing gas lines in Denver homes for 30 years. Stoves, fire pits, outdoor kitchens, new construction, and emergency gas line repairs done to code, every time.

Repair & Install

Tankless Water Heater Installation

Upgrade to endless hot water. We install and configure tankless water heater systems for Denver-area homes — proper sizing, correct gas line capacity, and clean installation that lasts.

Remodel

Bathroom Plumbing & Remodels

Planning a bathroom remodel in Littleton, Highlands Ranch, or anywhere in the Denver Metro? We handle the plumbing rough-in and finish work — coordinated around your contractor schedule, completed without surprises.

A Denver Plumbing Company Built on Family, Skill, and 30 Years of Trust

In 1994, Jim Unger started Colorado Plumbing & Gas Lines as a mom-and-pop operation. The idea was simple: be the kind of plumber that neighbors recommend — show up when you say you will, charge what's fair, and never cut corners on a gas line.

"Jim showed up exactly when he said he would — which almost never happens with contractors. He explained everything before starting, and the gas line install was clean, permitted, and inspected. Exactly right."

"Quoted me a fair price and charged me that price. He didn't try to sell me anything I didn't need. For gas line work especially, you want someone honest — this is your guy."

"Jim did our bathroom remodel plumbing and the new gas line for our outdoor kitchen. Showed up on time, coordinated with our contractor, and both jobs are perfect. Will use him again without hesitation."
