Cost of gas fireplace and installation — Ontario, CA

Last updated: September 24, 2026

What affects the price

When you look at getting a fireplace installed, several variables change the final bill. The biggest factor is the type of unit you choose—gas, wood-burning, or electric models all have different requirements. You also have to consider your home's existing ventilation and whether a chimney or direct-vent pipe needs to be built from scratch. If we need to run new gas lines or electrical circuits, that adds labor time and complexity. Your exact pricing is confirmed free on the call.

About this service

The total cost for a fireplace project combines the price of the appliance with the labor to install it, hook up the gas, and finish the surroundings. Factors like custom stonework, mantle installation, and venting runs significantly shift the final number. We walk you through all the options to fit your budget. Exact pricing confirmed free on the call.

Many people overlook summer for fireplace installations, but it is actually an ideal time. Because demand is lower, you can often secure a time slot that fits your schedule perfectly. It gives us plenty of time to focus on the technical details of your installation, ensuring a smooth process before the busy season hits.
