Gas fireplace insert installation cost — Denver, CO

Last updated: September 24, 2026

What affects the price

Fireplace pricing depends on your specific setup. If you already have a gas line or a chimney in place, the work is much simpler and cheaper. Installing from scratch requires more labor, including framing, venting, and finishing work with stone or tile. The type of unit—whether it is gas, wood, or electric—also changes the budget significantly. Larger units or custom hearth designs naturally add to the cost compared to basic inserts. We can discuss your project details and get exact pricing confirmed free on the call.

About this service

Installing an insert involves fitting a new gas unit into an existing masonry fireplace opening. The cost is influenced by the condition of your current chimney, whether a gas line needs to be extended, and the size of the insert. Simple replacements are less expensive than those requiring major liner upgrades. While costs vary, they are typically in the thousands. Exact pricing confirmed free on the call.

Summer might seem unusual for fireplace work, but it is actually the most efficient time to renovate. Contractors are often less busy, meaning you get more attention and faster installation times. By tackling this project now, you skip the waitlists that pop up once the temperature drops. You will be fully prepared well before the first frost arrives.
