Gas insert for fireplace — St. Paul, MN

Last updated: September 24, 2026

What affects the price

When estimating a gas fireplace project, several variables shift the final number. The type of unit—whether you choose a direct vent, vent-free, or an insert—plays a big role. You also have to account for the labor required to run new gas lines or update venting through your walls and roof. Customizing the surround, including stone, tile, or a new mantel, adds to the material costs. If you are converting an existing wood-burning fireplace, the complexity of the chimney liner installation will impact the total. Exact pricing confirmed free on the call.

About this service

An insert is a metal firebox designed to slide into your existing masonry fireplace to improve heating efficiency. Many homeowners choose this when their open-burning chimney loses too much heat or produces too much smoke. The installation involves sealing the chimney flue and running a gas line to the new unit. This upgrade transforms a drafty, inefficient fireplace into a powerful heater. Costs vary based on the unit size and venting requirements. Exact pricing confirmed free on the call.

Summer is the smartest time to plan a new fireplace installation or replacement. Because contractors are not dealing with the winter rush, you often have more flexibility with scheduling appointments. It is the perfect opportunity to renovate your fireplace surround or upgrade to a more efficient model while you aren't reliant on it for daily heat.
