While a hot fire can help heat up and loosen tar within your chimney, making it a recommended step before using a creosote log, it will not burn off significant existing buildup on its own. Attempting to remove built-up creosote with a hot fire is dangerous and can cause a chimney fire. For safe and effective removal of caked-on creosote, the best approach is to hire a professional chimney sweep.

A well-constructed and regularly maintained brick chimney can last 50 to 100 years, potentially spanning multiple generations of homeowners. The exact lifespan depends on the quality of construction, materials, local environment, and maintenance. In contrast, a metal chimney typically lasts 15 to 20 years. While the main structure is durable, individual components have shorter lifespans and require more frequent replacement. For example, mortar may need repointing every 20 to 30 years, chimney crowns last 50 to 75 years, and liners can last anywhere from 15 to 50 years depending on the material (e.g., stainless steel vs. cast-in-place).

The cost to install a pre-fabricated gas fireplace ranges from $2,000 to $7,500. The final price is influenced by several factors, including the specific model and size of the unit, the complexity of the venting, labor rates, and whether any structural modifications are required.

A sneaky but important element to how long your new fireplace runs is choosing the right burner size. Avoid choosing a bioethanol fireplace with a small burner (less than two gallons) and opt for one that holds between two to four gallons for a longer burn time or else you’ll be stuck frequently refilling your fireplace.
