Your chimney is designed to withstand Michigan’s harsh weather, but even the highest quality chimneys suffer wear and tear over the years. You may assume loose, cracked, or crumbling bricks around your chimney are just a cosmetic issue. However, it doesn’t take long for chimney damage to worsen, especially once water gets inside small cracks and weakens the mortar joints.
If you’re noticing signs of deterioration, it’s important to get your chimney inspected by a professional masonry contractor in Michigan before things get worse.
What Causes Chimney Bricks to Crumble?
Chimneys are exposed to everything from rain and snow to ice and temperature fluctuations, all of which can take a toll on brick and mortar. Water infiltration is the worst offender. Masonry is porous, which means it’s easy for moisture to make its way into small cracks.
When temperatures drop below freezing, that moisture can freeze and expand. As temperatures rise again, the ice thaws. Repeated freeze-thaw cycles gradually weaken the masonry and cause bricks to crack, flake, or crumble.
Other potential causes of damage include:
- Aging or deteriorating mortar
- Improper installation or previous repairs
- Excessive moisture exposure
- Damage to chimney flashing or caps
- Natural settling and movement
This is why it’s so important to identify the underlying cause. You can’t just replace a damaged brick without addressing the reason it deteriorated in the first place.
Why Loose Bricks Are a Problem
Loose chimney bricks are a sign that the surrounding masonry is compromised. As individual bricks deteriorate or become loose, water can enter the chimney, affecting surrounding bricks and mortar and expanding the damaged area.
Instability can result with enough time, which compromises structural integrity. Plus, loose bricks can fall from the chimney and land on your roof, driveway, patio, or other areas around your property.
Don’t Ignore Crumbling Mortar
Most Michigan homeowners notice damaged bricks first, but deteriorating mortar joints can be just as important.
Mortar naturally wears down over time, and damaged joints invite moisture deeper into the chimney. If the mortar is cracked, missing, or crumbling, repointing or tuckpointing may be necessary to restore the joints and help protect the surrounding masonry.
A Michigan masonry contractor can determine whether the problem is limited to the mortar or whether the bricks themselves also need to be repaired or replaced.
What Should You Do About Damaged Chimney Bricks?
Schedule a professional inspection at the first sign of trouble. An experienced masonry contractor can inspect the chimney, determine the cause of the deterioration, and recommend the appropriate repair.
The type of repair will depend on the underlying problem. Your contractor may:
- Replace individual damaged bricks
- Repoint deteriorated mortar joints
- Repair or replace damaged chimney components
- Address moisture or drainage issues
- Rebuild sections of severely damaged masonry
