What Is Chimney Tuckpointing?

Tuckpointing, also known as repointing, is the process used to restore damaged or old masonry by repairing the mortar joints between the bricks or stonework. Over time, weather exposure and other environmental factors can cause the mortar to deteriorate, leading to cracks and gaps. Tuckpointing involves removing the damaged mortar and replacing it with new mortar that matches the original in color and texture.

In order to understand the importance of chimney tuckpointing, it is crucial to understand the role that mortar plays in your chimney’s structure. Mortar has a starring role when it comes to the integrity of your chimney. It is responsible for binding the stones or bricks of your chimney, and it also prevents moisture from getting in.

Tuckpointing is an effective way to help strengthen your chimney’s structure and reduce the risk of further damage that could result in more costly repairs.

How Do I Know If My Chimney Needs Tuckpointing?

Chimneys that show signs of defects or damage are often prime candidates for chimney tuckpointing. As a homeowner, being aware of the signs of chimney mortar damage can help you be proactive in getting a certified and experienced chimney professional – like the crew here at Wolfman Chimney & Fireplace – out to restore your system. Common signs of mortar and chimney damage are:

  • Cracked Mortar: If you notice any cracks, no matter how small, this warrants an inspection by a qualified chimney professional. Even the most minute cracks can be responsible for letting water seep into the masonry, causing extensive damage over time.
  • Flaking Mortar or Spalling: Spalling is a term used to describe chimney bricks that have begun to flake and crumble. It can also cause bricks to become loose – and even fall out! It is typically caused by harsh weather and fluctuating temperatures. Even though the San Antonio area tends to have milder winters, your chimney can still be susceptible to spalling.
  • Damaged Drywall: If you notice damage to drywall around your chimney, a leak in your chimney due to cracked or broken mortar joints could be to blame. 
  • Discolored Mortar: Is masonry looking discolored? This can be a clear signal that it is deteriorating. You may notice it becoming lighter or experiencing stains.
  • Rusty Metal Components: If you notice rust stains in your firebox, on your chimney cap, or on your damper, chances are you have a leak of some sort in the masonry of your chimney. 

It’s important to be aware of the signs above and to check the masonry of your chimney on a regular basis. If you notice any concerns, be sure to call our chimney professionals out to inspect your chimney and discuss how we can get things back into good shape.

How Is Chimney Tuckpointing Done?

Chimney tuckpointing is a complex process that requires skill and experience. Here are the steps involved in tuckpointing a chimney:

  1. Inspection: The first step in tuckpointing is to inspect the chimney and determine the extent of the damage.
  2. Preparation: The chimney is then prepared for tuckpointing by removing any loose mortar, cleaning the surface of the chimney, and creating a smooth surface for the new mortar.
  3. Mixing the Mortar: The next step is to mix the mortar to match the color and texture of the existing mortar. This can be an intricate and time-consuming process, especially if your current mortar is on the older side.
  4. Applying New Mortar: The new mortar is then applied to the joints using a trowel. The joints are carefully filled, then any excess mortar is removed to create a clean, uniform finish.
  5. Finishing: Once the mortar has been applied, it’s left to dry and cure for several days. After drying, the chimney exterior is cleaned to remove any excess mortar.
