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.

About this service

The cost of installing a gas insert depends on your home’s existing setup, such as the condition of your chimney, the need for new gas lines, and the specific model you select. You should look into this when you want to convert a drafty wood-burning fireplace into an efficient, easy-to-use heat source. 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.
