Chimney ownership comes with maintenance duties and this includes the crown of the chimney; it needs servicing from time to time. This is an important part of the chimney that has the responsibility of shielding it from the weather conditions.

However, many homeowners do not know the times when the crown requires any attention. Should you choose to do repair work or go for a complete overhaul? By being able to identify the signs of damage and be able to act on it, you can prevent major problems in the future.

What Is a Chimney Crown and Why Is It Important?

The chimney crown is located above the chimney; the role of the structure is to prevent direct penetration of rain, snow or any other object falling on the flue. It is usually of concrete, stone or metal material and is of a permanent type. Well constructed chimney crowns assist in the prevention of water infiltration into the chimney system and overall damage of structure or potential development of hazardous mold.

In case the crown is removed, badly torn or worn out, your chimney becomes incapable of repelling water. This may lead to masonry decay, mainly with exposure to excess moisture, corrosion of metallic parts and in extreme conditions, chimney fires.

Signs Your Chimney Crown Needs Repair

Here are some indicators that a repair, rather than a full rebuild, may be the solution:

a. Minor Cracks or Chips

Some minor cracks are normal due to the thermal expansion or contraction of the material and can be repaired using a sealer to avoid worsening of the condition.

b. Surface Deterioration

When the deterioration is just on the surface, and the structure of the chimney crown is still strong, then repair should be enough.

c. Leaking or Moisture Signs

If water stains are present on the inner or outer walls of the chimney, then it may be possible to rectify the issue with a simple sealant.

When a Chimney Crown Needs Rebuilding

Sometimes reconstruction can also be needed on the chimney crown—for it to be as effective as needed. Here are the key reasons why a full rebuild may be required:

a. Extensive Cracking

It is also important also to note that if a crack goes deep into the crown or is widely spread, then repair might as well be the only option. It is usually better to rebuild, for it ultimately provides a safer structure.

b. Severe Water Damage

In case water has damaged the walls and the masonry or some of the internal chimney parts severely, a simple remedy will not be enough. A rebuild guarantees that there is maximum protection of both the chimney crown and all other adjacent areas.

c. Structural Weakness

When the crown has been compromised structurally due to the effects of time and battering, then it has to be reconstructed. Damaged chimney crowns may cause the chimneys to collapse, thus posing some danger to life and property.

Deciding to Reconstruct or to Repair

Crucial factors that determine the repair or reconstruction of the chimney include the intensity of the damage, the age of the chimney, and the construction materials. Hiring a chimney specialist is crucial since they are in the best position to determine whether your chimney crown needs repair or not.
