About this service
A ventless gas fireplace insert is a self-contained unit that slides into your existing masonry fireplace opening. You need this if you want to eliminate drafts from an open chimney and maximize heat output. Since it requires no venting, it is highly efficient at warming a living space. We verify your room size and ventilation requirements first, ensuring the unit operates safely while providing the warmth you need during the winter.
Many homeowners ignore their fireplace during the summer, but this is actually the best time to schedule an installation. Since demand is lower, you will likely find more flexibility in scheduling crews. You can get the project finished and out of the way, ensuring your home is ready to go the moment the first chilly breeze arrives.
