Install a gas fireplace insert — Thornton, CO
Last updated: September 24, 2026
What affects the price
When estimating a gas fireplace project, several variables shift the final number. The type of unit—whether you choose a direct vent, vent-free, or an insert—plays a big role. You also have to account for the labor required to run new gas lines or update venting through your walls and roof. Customizing the surround, including stone, tile, or a new mantel, adds to the material costs. If you are converting an existing wood-burning fireplace, the complexity of the chimney liner installation will impact the total. Exact pricing confirmed free on the call.
Summer is the smartest time to plan a new fireplace installation or replacement. Because contractors are not dealing with the winter rush, you often have more flexibility with scheduling appointments. It is the perfect opportunity to renovate your fireplace surround or upgrade to a more efficient model while you aren't reliant on it for daily heat.
