You will know if you have this type of chimney by looking at the firebox. If you see yellowish firebrick, a specialized masonry material that can withstand extremely high temperatures, then you have a masonry chimney. It is durable and dependable, a masonry chimney and fireplace system should give you years of cozy and warm fires.

However, you do need to keep up with a few important maintenance responsibilities to prolong the life of this system. To help you with these tasks, All Seasons Chimney provides professional chimney sweeping and inspection services. It is recommended by the industry experts like the Chimney Safety Institute of America (CSIA) to have at least one sweeping and inspection a year. We also offer waterproofing treatment services to protect your masonry chimney against water penetration.


If you look into your firebox and see refractory panels, you have a prefabricated chimney system. This type of chimney system is manufactured from metal, and it is designed to be installed as a complete unit. Growing in popularity over the past several decades, factory-built systems typically include a chase made of wood or masonry materials. The wood or masonry materials hide the metal chimney pipe so that it looks like a traditional chimney.

Although this type of chimney can give you years of service, you should know that they don’t last as long as masonry chimneys. For safety reasons, you should look out for signs of aging such as cracks in the firebox panels. Cracks and aging of these systems can lead to an increased risk for residential fires. You should also be careful to not overuse your prefab fireplace, as these units are generally not made for heavy use.

The installation instructions of a prefabricated chimney must be followed exactly.

Prefabricated chimney systems have specified clearances from the firebox and the chimney to any combustible materials. If these clearances are not met, it can be a dangerous fire hazard. This is why professional installation of prefabricated chimney systems is so important. You can trust All Seasons Chimney to follow all clearance guidelines when installing your system.

Prefabricated fireplaces are tested and listed as decorative heating appliances.

This means that a prefabricated fireplace cannot take severe overfiring as this can result in devastating chimney fires. Before you use your new fireplace system, it is essential to read the instructions thoroughly. Keep the operating manual in a safe place so that you can reference it if needed. Regular maintenance of your prefabricated chimney system is also recommended.

Prefabricated chimneys can be a favorite nesting spot for birds and other animals.

The importance of covering your prefabricated chimney with a chimney cap equipped with meshing on its side is crucial to prevent birds and animals from nesting within the chimney. Many times the chimney caps that come with prefabricated chimney systems are not very effective at keeping birds and animals out. Our technicians at All Seasons Chimney have years of experience in making prefabricated chimneys safe from bird and animals invasions, and we can help you find the perfect chimney cap to prevent bird and animal nesting from blocking your chimney and becoming a fire hazard.

Regular maintenance of your prefabricated chimney system is essential.
