About CMJ Installations

A proud family business bringing warmth and craftsmanship to Long Island homes for over four decades.

Our Heritage

Family-Owned & Operated Since 1981

For over 43 years, CMJ Installations has been the name Long Island families trust when it comes to fireplaces and stoves. What began as a small family operation has grown into one of the most respected names in the hearth industry on Long Island.

We believe that a fireplace is more than just a heat source — it's the heart of a home. That's why we approach every installation with the same care and attention to detail we would give our own homes.

Our team treats every customer like family, providing friendly, expert guidance every step of the way — from your first consultation through the final installation and beyond.
