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).

A hearth often looks like a tile or brick floor that juts out from and surrounds your fireplace. A hearth can be made of stone, brick, ceramic, or any other fireproof material. Brick offers a classic and traditional vibe, whereas a hearth made of marble or ceramic may lean more toward modern aesthetics. The most common depth of a hearth is 20 inches.

Yes, you can have a gas line professionally installed to convert your traditional fireplace to natural gas; just know it’ll be an extra cost to budget for. The cost to run a gas line where you don’t already have one is about $540, though most homeowners pay between $260 and $820. Your total could be significantly higher if you don’t already have a main gas line running to your home.

A fireplace can increase a home's value by as much as 12%, with some reports indicating that homes with fireplaces list for around 13% more than the median sale price. Fireplaces are both functional and aesthetically pleasing, adding a charm that many homebuyers find desirable. The actual return on investment depends on the fireplace's size, type, and material.

However, a fireplace can detract from a property's value if it is unusable, not up to code, or in need of immediate repairs. The type of fireplace also matters; custom electric fireplaces and inserts can add value, while freestanding units that can be removed have less impact.
