Gas fireplace insert installation cost — Lakewood, CO

Last updated: September 24, 2026

What affects the price

When you start planning a fireplace installation, the final bill depends on a few major factors. Choosing between a simple electric unit, a gas insert, or a full wood-burning masonry build creates the biggest difference in cost. You also have to consider the existing setup of your home; running new gas lines or venting through a roof will naturally add labor hours compared to a straightforward swap. Finishing materials like custom stonework or mantel pieces also shift the total.

About this service

The price varies based on the size of the insert, the condition of your existing chimney, and whether you need a new liner installed for proper venting. If your chimney requires significant repairs before the insert can be placed, that will also influence the total investment. We provide exact pricing confirmed free on the call.

Fall is the final window to get your fireplace ready before the heavy use of winter begins. As the air turns crisp, interest in installations spikes. We recommend getting your project on the books as soon as possible to ensure your fireplace is installed and inspected before the first frost arrives. It is the perfect time to ensure everything functions perfectly.
