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 cost to install a gas insert depends on your home’s venting setup, the size of the unit, and any necessary gas line modifications. You will need this service if you are looking to convert an existing wood-burning masonry fireplace into a more efficient, cleaner-burning gas system. An inspection of your chimney and flue is required before we start to ensure safety and code compliance. Exact pricing confirmed free on the call.
