We know our customers time is valuable, so we set exact appointments and do our best to stay on schedule. We don't think it is fair to give a 2 or 4 hour window of time. Just like a tune up on your car, your gas fireplace should be cleaned, serviced and adjusted every year to 2 years to keep it running more efficiently, pick up on any problems such as gas or CO leaks, and help the fireplace last longer and operate more safely. By using your fireplace, you can help cut down on heating costs in your home. Our Technicians are factory trained, NFIcertified and insured. All our work carries a 30 day warranty. *Ask for details We set exact appointments. We service 1,000's of fireplaces each year.
