What affects the price

The final price for a new gas fireplace depends on a few moving parts. First, you have to consider whether you are installing a unit into an existing chimney or creating a new opening in a wall, which adds labor. The type of venting required and the current proximity of your gas lines also play a big role in the complexity of the install. Aesthetic choices, like premium stone surrounds or remote-controlled flame features, will adjust the total as well.
