About this service

When your gas fireplace fails to turn on, makes unusual noises, or has soot buildup, it is time for a repair. We troubleshoot the ignition system, gas lines, and venting to find the source of the problem. Sometimes a simple cleaning of the sensors is all it takes; other times, a part needs replacement. Addressing these issues early prevents minor mechanical failures from turning into larger safety hazards.

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.
