Your chimney sits high above your roof and is one of the most exposed parts of your home. Because of this, it is subjected to all the outdoor elements, year after year—rain, snow, wind, heat, and ice. In time, this exposure can result in the mortar deteriorating between the bricks that hold your chimney together. 

This is why repointing is necessary. 

Unfortunately, many New York homeowners do not realize that their chimney is quietly failing until major damage is visible. So, knowing the early warning signs of mortar deterioration can help you to avoid major repairs in the future. 

What is Chimney Repointing? 

Repointing is the process of removing the mortar that has started to chip away, clearing out the joints between bricks. It is then replaced with fresh mortar. While this is a very important step in restoring the integrity of your chimney, its benefit does not stop there. 

Chimney repointing is also helpful in keeping moisture out. If you enjoy having a functional fireplace at your fingertips, ensuring the chimney is healthy and structurally sound is essential. 

Tip: Mortar is softer than brick, and it will wear down first. Once it begins to take action. 

Gaps in Mortar or Visible Cracks

Sometimes you can simply look at your chimney and notice when the mortar is crumbling. Maybe you will only see cracks, with mortar that is sandy and flaky. Or, maybe mortar will be missing in its entirety. These are all signs that should catch your attention. 

Anytime the mortar is impacted, moisture can seep in, and damage will only accelerate going forward. What’s worse, it is amplified during freeze-thaw cycles that are so common throughout New York during the colder months. 

Loose Bricks

Mortar holds the bricks in place. As they begin to wear, often appearing cracked or chipped, they can lose the support they need. The bricks will eventually begin to come loose and break apart, a condition known as spalling.

If you find yourself in this situation, repointing is critically necessary to prevent the need for an entirely new chimney. 

Water Leaks or Interior Staining

Since mortar issues can lead to moisture problems, if you have signs of water leaks or staining inside your home, you may be able to trace it back to your chimney. Keep an eye out for stains that appear on the walls or ceilings near the area, as well as dampness in the fireplace or musty odors. 

All of these things can indicate that your chimney has failing mortar joints. Investing in chimney repointing can seal up these vulnerable areas and keep water out. 

Appearance of Efflorescence 

Have you ever noticed a chalky white residue on the outside of your chimney? This is known as efflorescence. This residue is not dangerous, but it should signal to you that moisture is getting through the masonry and dissolving salts inside the mortar. 

If you are paying attention, this could be your first sign that your chimney needs help. 

The Age of the Chimney

With age, a chimney requires repointing, even if it was made with high-quality material and craftsmanship. If yours is between 20 and 30 years old and has never undergone this treatment, there is a good chance your mortar could start making a scene at any moment. 

Regular inspections will allow us to catch any signs of deterioration early, making repointing easy and more affordable. Don’t overlook this routine care so that you can count on your chimney for years to come.
