Your Old Fireplace, Reborn as a Real Heater
Why Choose a Gas Insert
An open masonry fireplace sends most of its heat up the chimney—and pulls warm room air with it. A gas insert seals that hole with a high-efficiency firebox that heats the room instead of the sky.
We fit inserts from Mendota, Kozy Heat, and more into existing fireplaces every week: measured right, lined right, and finished with the surround panels that make it look born there.
Bring a photo and the opening's measurements—you'll get a straight answer on what fits and an installed estimate in minutes.

What the Tri-State Says
Reviews From Our Customers
What customers say after the work is done.
"Can’t begin to say enough about our positive experience with Tate Builders Supply. Fourteen years ago we visited their show room looking for a fireplace costing $8,000, but the salesman, Tim Duncan, suggested a lower costing brand. It has been just wonderful all these years. Embarrassing we have not had the fireplace serviced until today. Jimmy did a wonderful job. He showed us several things about the fireplace we never knew, like that there are ambient lights in the rear. I highly recommend Tate Building Supply and their employees."

"Tate Builders did a phenomenal job working on my natural gas fireplace. I could not be happier! They promptly scheduled my appointment, diagnosed and fixed the problem within 30 minutes, cleaned the fireplace to make it look like new, added some aesthetic charm, charged me an exceptionally reasonable rate, and Jim could not have been better to work with. He was professional and courteous and took the time to educate me about my fireplace as he was working. Perfect experience all around. I will absolutely go back to them again for regular maintenance and any further issues."

"Tate Builders did an absolutely fantastic job repairing my chimney and replacement my entire fireplace. The work was extensive and my family and I were amazed at how efficient they worked. Within two days, 95% of the work was done! Plus, the men were kind and friendly around my family and that was very surprising. I couldn't recommend Tate Builders more highly!"

What is a gas insert?
A sealed gas fireplace that slides into your existing masonry fireplace and vents through the chimney with a flexible liner. It turns an open, drafty fireplace into an efficient heater you run from a remote.
Will a gas insert fit my fireplace?
Most masonry fireplaces accept an insert, but the opening size determines which models fit. Bring the width, height, and depth of your opening to your appointment, or send a photo, and we'll match it.
