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

An insert is designed to fit inside your existing masonry fireplace. The cost fluctuates based on the size of the insert, the condition of your current chimney, and the complexity of the gas line hookup. If your chimney requires a new liner, that adds to the total labor. 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.
