What affects the price

The final price for your gas fireplace installation depends on several moving parts. It starts with the unit itself—whether you choose a basic insert or a high-end designer model with custom stone work. We also look at your existing venting setup; if we need to run new lines or modify your chimney, labor costs will increase. Gas line access and electrical requirements are other variables that shift the total investment. We can provide exact pricing confirmed free on the call.

About this service

Adding a gas insert involves several factors that shift the bottom line, such as the size of your existing masonry opening, the complexity of the gas line plumbing, and the venting requirements for your specific chimney. We provide a professional assessment to ensure your setup is safe and efficient. Exact pricing confirmed free on the call.

Summer is the best time to upgrade or install a new system. Since demand is lower, you can often coordinate installation around your vacation schedule or home renovation projects. Tackling the installation now means you will be ahead of the rush when the first frost arrives later in the year.
