What Is a Masonry Fireplace?
A masonry fireplace is a site-built appliance using stone, brick, and mortar, containing a refractory brick firebox which leads to a smoke chamber and a chimney chase with a flue that extends above the roof. It is usually built onsite as part of the house. Despite the emergence of various prefabricated fireplace designs, many people still prefer masonry fireplaces for their classic, rustic appeal and versatility.

Here are some signs indicating that you are due for chimney masonry repair services:
- Cracks in the chimney crown: The chimney crown is the cement cover over the top of the chimney. It is usually the first part to wear out due to exposure to the elements. Normally, it needs to be replaced every 20 years, but a cracked one may need replacement sooner. Cracks in the crown can allow water in, which can freeze, expand, and cause more harm. Many times, a cracked crown can be fixed with a waterproof sealant. But if it is too damaged for this, a partial or full rebuild may be necessary to protect the chimney’s integrity.
- Damaged walls or ceiling near chimney: Any damage to the walls or ceiling near your chimney could be from too much moisture in the chimney or heat escaping through cracks in the flue liner. If you spot any of these issues, you need to take care of them right away, definitely before using the fireplace again.
- Spalling bricks: "Spalling" is when the outer layer detaches from the brick. This happens when water gets into brick, stone, or concrete, causing the surface to burst, peel, or chip away. You can usually spot spalling because there will be pieces of brick or stone on the roof or the ground from the chimney. If you don’t fix this issue, the bricks will continue breaking down, which could ultimately lead to the whole chimney falling apart.
- Ineffective mortar joints: Mortar joints help to keep bricks secure. If these joints get damaged, it could lead to problems with the entire brick structure. If the mortar joints are cracked or worn, they need called tuckpointing. When done correctly, tuckpointing lasts a long time, but elements like harsh weather and improper mortar mixcan affect a chimney more than other house parts. That is why it is so important to regularly inspect chimneys and keep an eye out for any problems or signs you need chimney masonry repair.
Other common issues that indicate you need chimney or masonry repair services include worn caulking, pieces of brick or flue tiles in your firebox, excessive smoke, or rust.
