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

When your gas fireplace acts up, it usually involves problems with the ignition system, thermocouple, or burner assembly. If the flames look weak, the fireplace won't turn on, or the remote isn't communicating with the unit, a technician needs to inspect the internal components. We diagnose the root cause to restore warmth to your living space. Getting these issues fixed promptly ensures your unit stays safe and functional throughout the colder months. Let us handle the technical side of your fireplace.

Many people think about fireplaces only in the cold, but summer is actually a great time to schedule an installation. Since demand is lower, you can often get your project finished without the long wait times seen during the peak winter months, making sure you are ready before the first frost arrives.
