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).

Yes, it is possible to convert a wood-burning fireplace to gas. The average cost for this conversion is $3,000, with a typical range of $500 to $5,500. The project involves running a gas line, professionally cleaning the chimney, and installing gas logs.

Cost factors include the type of gas fireplace and whether a new gas line is needed. Installing a natural gas line can add $200 to $1,000 to the cost. Vented gas fireplaces are more expensive, averaging around $5,000, while ventless options are more cost-effective at about $1,500.

Most projects take 5-10 days, including foundation work, masonry, and finishing.

While you have some flexibility in the types of wood you can use in your outdoor furnace, it's important to make wise choices for optimal performance and efficiency. Hardwoods, such as oak, maple, and cherry, are generally recommended for their higher energy content and cleaner burn. These hardwoods produce more heat per volume and tend to produce fewer creosote deposits, which can accumulate and cause a chimney fire, according to the U.S. Environmental Protection Agency.
