What affects the price

When you are looking at wood fireplaces, the final cost depends on several moving parts. Choosing between a pre-fabricated insert and a custom masonry build is the biggest factor. You also have to think about venting requirements, the type of chimney lining needed, and the finish materials like stone or brick veneer. If your home needs structural modifications to meet current safety codes, that will add to the labor hours. We look at your specific setup to provide a clear path forward.

About this service

A wood-burning insert is a metal box designed to slide into your existing masonry fireplace. It transforms an inefficient open hearth into a high-output heating source. You should look into these if your current fireplace smokes, sends all the heat up the chimney, or feels drafty. These units use glass doors and internal air circulation to trap heat inside your living space rather than losing it to the outdoors, making them a practical upgrade for colder months.
