What affects the price

The final cost of a wood fireplace depends on several key variables. First, consider the complexity of the installation, specifically if you require new chimney venting or structural modifications to your wall. The size and heat output capacity of the unit also play a major role, as larger models naturally cost more to source. Choosing between a prefabricated insert and a custom masonry build changes the labor intensity significantly. You might also add custom finishes, such as stone or brick surrounds, which adjust the total investment. Exact pricing confirmed free on the call.
