What affects the price

When you budget for a new fireplace, the final number depends on several moving parts. Choosing between a simple electric insert and a complex gas or wood-burning setup changes labor needs significantly. If your home already has a chimney or gas line, costs stay lower. If we need to run new venting, cut into walls, or add custom stonework, the labor and material requirements increase. Every home layout is unique, and we look at your specific space to provide a plan. Exact pricing confirmed free on the call.
