Read about the must-haves for chimney maintenance.
A chimney is more than just a feature – it’s a part of your home that makes your fireplace safe and looks great. Whether you have a traditional brick chimney or a modern metal chimney, maintenance is key to prevent damage and extend its life. Here’s how to look after your chimneys.
1. Check for Cracks and Damage
Chimneys, especially brick ones, get small cracks over time from heat, freezing, and moisture. Checking for cracked brick or mortar joints will prevent water damage, structural issues, and even safety hazards in your home.
What to Do: Inspect regularly—both inside and out—to catch cracks or deterioration early.
Pro Tip: If you see mortar or bricks deteriorating, call a professional to fix them before the damage worsens.
2. Water Damage
Water is the enemy of brick chimneys. Without waterproofing, bricks absorb water, which freezes and expands in cold weather, causing further cracks and weakening of the structure. Metal chimneys can rust and tear from prolonged exposure to the elements.
How to Protect:
- Install a chimney cap to keep the flue dry from rain and debris.
- Apply masonry water repellent to stop water from getting into the bricks.
3. Check and Fix Flashing
Flashing, the material that seals the chimney to the roof, can deteriorate over time. Leaks around the flashing can cause water to drip into the ceiling and rot and mold.
How to Maintain:
- Check the flashing for gaps or rust.
- Replace damaged flashing to seal tight.
4. Chimney Crown
The crown protects your chimney from the elements. However, over time, it can crack, allowing moisture to enter the chimney system.
How to Fix the Crown:
- If there are small cracks, use a sealant to smooth and fix them.
- For severe damage, the crown may need to be replaced by a pro.
5. Clean Regularly
Whether you have a brick or metal chimney, cleaning the inside flue is key to removing soot, creosote, and debris from wood-burning fireplaces. High temperatures from wood-burning fireplaces can cause excessive creosote buildup, which is a fire hazard. Excessive creosote buildup is a fire hazard.
Cleaning:
- Done with specialized tools like brushes.
- Schedule a pro cleaning annually to be safe.
6. Repair or Replace Damaged Parts
As chimneys age, builders recommend replacing worn-out parts like cracked bricks, deteriorated mortar, or corroded metal parts. Repairing these areas will extend the life of your chimney and keep it safe.
7. Masonry and Stone Repairs
For brick chimneys, mortar joints are the backbone that holds everything together. Over time, these joints can crumble and leave your chimney vulnerable to collapse. Stone chimneys are more robust but still need attention to prevent damage.
Tips:
- Repoint to fix weak mortar joints.
- Use good quality materials for a long-lasting repair.
8. Inside and Out
The inside flue and the outside structure need equal attention. While cleaning takes care of the inside, the outside needs attention to prevent moisture and deterioration.
9. Seasonal Maintenance
Chimneys face different challenges throughout the year. In summer, inspect for water damage or cracks formed during cold weather. Before winter, make sure your chimney is ready for regular use and high temperatures from frequent fires.
10. Call a Pro When in Doubt
DIY can handle small cracks, but bigger problems like major damage or extensive repairs require expert knowledge. A pro can figure out the solution and build a solution for your chimney.
