Cost to Outdoor Fireplace Construction in Boston, MA (2026)

If you’re budgeting a outdoor fireplace construction in Boston, most projects run $3,573-$17,864, 19% above the $7,500 national average. What moves that number most is usually one thing: Prefab Kit vs. Custom Masonry. On its own it can swing the cost by $3,000 - $15,000, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Use a prefab kit instead of full custom masonry. A quality prefab fireplace insert costs $1,500-$3,000 and installs in a fraction of the time. Add manufactured stone veneer around it for a custom look at a fraction of the price.
