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

Gas fireplace installation is the process of setting up a new heat source, which may involve framing, gas line plumbing, and exterior venting. It is an ideal project for homeowners looking to add warmth to a room that currently lacks a fireplace or for those upgrading from outdated equipment. We ensure the entire system is properly ventilated and safe for daily use. Exact pricing confirmed free on the call.

Summer is the smartest time to plan a new fireplace installation or replacement.
