Fireplace insert installation cost — Ontario, CA

Last updated: September 24, 2026

What affects the price

When you budget for a new fireplace, the final number depends on several moving parts. Choosing between a simple electric insert and a complex gas or wood-burning setup changes labor needs significantly. If your home already has a chimney or gas line, costs stay lower. If we need to run new venting, cut into walls, or add custom stonework, the labor and material requirements increase. Every home layout is unique, and we look at your specific space to provide a plan. Exact pricing confirmed free on the call.

About this service

This involves retrofitting a new, efficient firebox into an old masonry fireplace. The cost depends on the type of fuel—gas, wood, or electric—and the work required to prepare the existing chimney. We assess your chimney’s condition to determine the final scope of work. Exact pricing confirmed free on the call.

Installing during the summer is a smart way to prepare for the colder months ahead. While it may seem counterintuitive to think about fire when it is hot outside, this is often the best window to get better pricing on units and shorter wait times. Your fireplace will be ready to go the moment the first chilly evening arrives.
