You can build a fireplace on an existing house, but it’s much easier to construct a masonry fireplace when building a new house. To add to an existing house, you’ll need to build a chimney and ensure the foundation can support a true masonry fireplace. Alternatively, you can purchase a gas or electric fireplace insert, which isn’t as complicated to add to an existing structure.

The cost to replace a chimney is about $10,000 on average and can cost up to $15,000, depending on the size, accessibility, materials, and extent of the replacement. Sometimes tearing the chimney down to the roof line and rebuilding it is an option. But if the chimney's internal structure deteriorates badly enough, a complete demolition down to the fireplace or the foundation may be necessary.

Both vented and ventless gas fireplaces have pros and cons, and the best choice depends on your needs and preferences. A ventless fireplace may be a good option if you do not have a chimney, but you should check local regulations as they are banned in some areas, such as California. On the other hand, if anyone in your household has allergies, asthma, or other respiratory sensitivities, a vented fireplace is a better choice for health and air quality.

Professional chimney cleaning, also known as chimney sweeping, typically costs between $130 and $400, with a national average of about $260. The final price depends on several factors, including the size and accessibility of your chimney, the number of chimneys being cleaned, and the type of chimney you have. A standard cleaning involves a chimney sweep scraping creosote, dirt, and other debris from the entire flue. Many professionals also include an inspection with this service, but the cost of any necessary repairs is typically extra. Additional services, such as installing a fireplace damper, will also increase the total cost. It is recommended to schedule a cleaning and inspection annually, preferably before you begin using your fireplace for the season, and to get price quotes from at least three companies to find the best deal.
