Cost to install gas fireplace insert — Boulder, CO

Last updated: September 24, 2026

What affects the price

The final price for your gas fireplace installation depends on several moving parts. It starts with the unit itself—whether you choose a basic insert or a high-end designer model with custom stone work. We also look at your existing venting setup; if we need to run new lines or modify your chimney, labor costs will increase. Gas line access and electrical requirements are other variables that shift the total investment. We can provide exact pricing confirmed free on the call.

About this service

The cost to install an insert depends heavily on whether your chimney needs a new stainless steel liner and how far the gas line must be routed. We assess your home's unique configuration to provide a clear estimate before any work begins. Exact pricing confirmed free on the call.

Summer is the best time to upgrade or install a new system. Since demand is lower, you can often coordinate installation around your vacation schedule or home renovation projects. Tackling the installation now means you will be ahead of the rush when the first frost arrives later in the year.
