Keep Chimneys in Good Shape, Part 2: Types of Maintenance

Masonry chimneys are always exposed to elements that cause deterioration and structural problems. When there are damaged components, it is important to have them repaired immediately to prevent bigger issues.

At Garlock-French Corporation, we specialize in the following maintenance services that will extend the life of your chimney and keep your home safe.

Tuck-Pointing

Tuck-pointing is a process where the damaged mortar is replaced with fresh ones. We grind out the old mortar and fill the empty space with mortar that matches the chimney. This is one of the most common maintenance tasks for any masonry chimney. Tuck-pointing offers the following benefits:

  • Increased water resistance
  • Enhanced chimney look
  • Prevention against firebox deterioration and moisture damage

While checking the chimney on your roofing in St. Paul, we sometimes notice that the entire chimney will need tuck-pointing. In this situation, we use a concave shape to provide the best weather resistance.

Clay Flue Replacement

Clay flues are the lining placed inside your chimneys to contain the combustion of byproducts and direct them outside. It also protects chimneys from corrosion, debris, and rain. These liners come in varying sizes and are supported by masonry. Replacing liners keeps all unnecessary things away from your chimney.

Chimney Crown Rebuilding and Replacement

The chimney crown, also called chimney caps, protects the rest of the chimney components. It is specially designed to keep moisture away from the system. It is sloped away from the flue or liner to direct water effectively.

Chimney crown replacement prevents mortar, discovers and cleans up rot. When we rebuild the chimney crown, we apply sealant around the flue and assess other components of the system.

Rebuilding

When your chimney is too damaged upon assessment, we will recommend a complete rebuilding of the system. This typically happens when the damage is further down the base or is around several areas. Broken or cracked clay flues also need complete reconstruction of the chimney.
