Gas fireplace insert installation cost — Joliet, IL

Last updated: September 24, 2026

What affects the price

Fireplace pricing depends on your specific setup. If you already have a gas line or a chimney in place, the work is much simpler and cheaper. Installing from scratch requires more labor, including framing, venting, and finishing work with stone or tile. The type of unit—whether it is gas, wood, or electric—also changes the budget significantly. Larger units or custom hearth designs naturally add to the cost compared to basic inserts. We can discuss your project details and get exact pricing confirmed free on the call.

About this service

Installing an insert involves fitting a new gas unit into an existing masonry fireplace opening. The cost is influenced by the condition of your current chimney, whether a gas line needs to be extended, and the size of the insert. Simple replacements are less expensive than those requiring major liner upgrades. While costs vary, they are typically in the thousands. Exact pricing confirmed free on the call.

Fall is the busiest season for fireplace professionals. As the air turns crisp, everyone wants their hearth ready for the holidays. While this is a popular time, we recommend calling as soon as you decide to move forward. We will do our best to find a slot that fits your timeline before the real cold sets in.
