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.

About this service

The total cost for a gas fireplace insert is driven by the type of insert you select, the existing condition of your chimney, and the labor required to connect gas and electrical lines. Choosing a unit with higher efficiency or premium decorative features will impact the final amount. Exact pricing confirmed free on the call.

Many people think about fireplaces only in the cold, but summer is actually a great time to schedule an installation.
