A As the fall season arrives in Illinois, the chill in the air means it’s time to check in on one of the most important structures of your home: your chimney and masonry. With dropping temperatures, your chimney endures a lot more wear and tear, making fall the ideal time for inspection and repairs.
Keeping an eye out for common masonry and chimney issues can help prevent costly damage and keep your home safe and cozy through the winter. Here’s a look at the top issues you should be aware of—and guidance on when it’s time to call in the professionals.
.
1. Cracked or Missing Mortar
Why It’s a Problem: Mortar holds the bricks of your chimney together. Over time, it can crack and deteriorate due to weather, moisture, and temperature changes. In cold weather, cracks in mortar can worsen as water seeps in, freezes, and expands, causing further damage.- When to Call a Pro: If you spot cracks, crumbling mortar, or even pieces of mortar on the ground around your chimney, it’s time for a professional inspection. A mason can perform tuckpointing, a process of filling in missing mortar to restore the structural integrity of your chimney.

2. Chimney Blockages
- Why It’s a Problem: Blockages caused by debris, birds’ nests, leaves, or other obstructions prevent smoke and fumes from escaping properly. This increases the risk of harmful gases, like carbon monoxide, backing up into your home.
- When to Call a Pro: You should have your chimney professionally inspected and cleaned each year. If you haven’t done this already for the season, schedule a cleaning right away to ensure a clear flue and safe venting.

3. Spalling Bricks
Why It’s a Problem: Spalling happens when moisture enters the bricks, causing them to chip, flake, or pop out as the temperature drops. It weakens the chimney and can lead to more significant structural problems if left untreated.- When to Call a Pro: If you notice any bricks that appear chipped, flaking, or damaged, contact a masonry professional immediately. They can help repair or replace affected bricks to prevent more extensive damage.
.
4. Damaged Chimney Crown
- Why It’s a Problem: The chimney crown protects your chimney from water entry. Over time, crowns can crack or degrade due to exposure to the elements, allowing water to seep inside. Water penetration can lead to internal chimney damage and, in colder weather, ice expansion, which can further weaken the structure.
- When to Call a Pro: A cracked or damaged crown needs professional attention. A specialist can seal small cracks or, in more severe cases, replace the crown entirely to prevent water damage.
.
5. Rust and Corrosion on the Chimney Cap
- Why It’s a Problem: The chimney cap prevents rain, debris, and animals from entering your chimney. If rust or corrosion affects the cap, it can lead to water and pest intrusion, blocking airflow and causing additional damage.
- When to Call a Pro: Check for visible rust or signs of corrosion. If you notice damage, consult a chimney professional who can replace or repair the cap to ensure it’s protecting your chimney effectively.
.
6. Efflorescence (White Stains on Brick)
- Why It’s a Problem: Efflorescence appears as white stains on the masonry, caused by water seeping through and bringing salt to the surface. While it’s not damaging itself, it’s a sign that your chimney may be absorbing too much moisture, which can lead to structural issues over time.
- When to Call a Pro: Regular cleaning can keep efflorescence under control, but if it persists, it’s wise to contact a professional. They can assess whether waterproofing or other preventive measures are needed to protect your chimney.
.
7. Draft Problems or Smoke Backing into the Home
- Why It’s a Problem: If you notice smoke coming back into your home instead of flowing out through the chimney, this could indicate a drafting problem, blockages, or an issue with your chimney height or cap.
- When to Call a Pro: Drafting issues can be complex to diagnose. A chimney professional can determine the cause of the problem and recommend solutions to improve airflow and keep your home safe.
