Gas Fireplace Service questions, answered by experts

Chimney crowns should be at least 2 inches thick at their thinnest point. If the crown is thinner than 2 inches, it’s more likely to be damaged and allow water to seep into the chimney.

Fireplace inserts can increase home value when installed correctly. Since they improve heating efficiency significantly, this will be a bonus to homeowners who are looking for a functional alternative heat source. Plus, inserts are less maintenance and less of a liability than a traditional fireplace. You’re very likely to recover fireplace insert installation costs when you sell your home.

If you have a chimney, you need a flue or chimney cap. The right covering keeps rain, debris, and animals from getting into your flue or chimney and causing damage. A flue or chimney cap also provides fire protection. The mesh insert around the cap keeps sparks from flying out of the chimney and igniting leaves and other materials.

Wood is classified as either hardwood or softwood. While both are good options for firewood, hardwoods like oak, hickory, beech, cherry, elm, and maple tend to be the best quality. These woods burn longer and hotter than softwoods and often produce less smoke. As an added bonus, woods like oak, hickory, and cherry emit a sought-after scent that is sure to make your home extra cozy.

Yes, you can install a liner in an old chimney that is in good working condition. In fact, it's often necessary for safety and efficiency. Older chimneys may lack liners or have deteriorated ones, leading to heat damage, gas leaks, or reduced performance. Installing a stainless steel, clay tile, or cast-in-place liner improves safety, protects the chimney’s structure, and boosts energy efficiency. This upgrade can extend the life span of an old chimney while meeting modern safety standards.
