Gas fireplace installation cost — Trenton, NJ

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

The final price for installing a gas fireplace depends on whether you have existing gas lines, the type of venting required, and the complexity of the unit you select. If you need to run new gas lines or build a new chimney, expect the price to rise. While project totals vary, they are typically in the thousands. Exact pricing confirmed free on the call.

Summer might seem unusual for fireplace work, but it is actually the most efficient time to renovate. Contractors are often less busy, meaning you get more attention and faster installation times. By tackling this project now, you skip the waitlists that pop up once the temperature drops. You will be fully prepared well before the first frost arrives.
