Cost of a gas fireplace 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.

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.
