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

You need this service if you want an all-in-one project completed by professionals who handle the heavy lifting and technical certifications for you. 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.
