Gas insert in fireplace — Manchester, NH

Last updated: September 24, 2026

What affects the price

When you are looking at gas fireplaces, the final cost depends on several moving parts. It starts with whether you are installing a brand new unit or upgrading an existing masonry hearth. You will need to consider the complexity of the gas line installation, the venting requirements, and any custom stonework or finish carpentry needed to make it look right in your living room. Size and heat output also play a role, as larger units for bigger spaces naturally require more materials. Exact pricing confirmed free on the call.
