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.
