Wood fireplace installation cost — O'Fallon, MO
Last updated: September 24, 2026
What affects the price
When you start planning a fireplace installation, the final bill depends on a few major factors. Choosing between a simple electric unit, a gas insert, or a full wood-burning masonry build creates the biggest difference in cost. You also have to consider the existing setup of your home; running new gas lines or venting through a roof will naturally add labor hours compared to a straightforward swap. Finishing materials like custom stonework or mantel pieces also shift the total.
