The Most Common Chimney Issues in Innisfil — And How We Fix Them
.jpg)
At Chameleon Masonry, we’ve worked on countless chimneys across Innisfil and the surrounding area — and we’ve seen it all. Whether you're dealing with an older brick chimney or a newer build that wasn’t properly maintained, chimney problems in our region tend to follow a few common patterns. The good news? We know exactly how to fix them.
Here’s a look at the most common chimney issues we see in Innisfil, and how our team at Chameleon Masonry handles each one.
1. Cracked or Spalling Brickwork
The Problem:
With our harsh freeze-thaw cycles in Ontario, brickwork takes a beating. Water seeps into the bricks and freezes, causing the outer layers to flake off — a process called spalling. Left unchecked, it compromises the chimney’s structure.
How We Fix It:
We remove and replace damaged bricks using high-quality, weather-resistant materials. We also inspect the mortar joints and repoint them if necessary to restore structural integrity and prevent future damage.
2. Deteriorating Mortar Joints
The Problem:
Mortar doesn’t last forever — especially in a climate like Innisfil’s. Over time, it can erode, crack, or crumble, allowing water and cold air to penetrate your chimney.
Our Solution:
We perform tuckpointing (also known as repointing), where we carefully remove the damaged mortar and replace it with new mortar that matches your existing structure. This not only strengthens your chimney but also restores its appearance.
3. Chimney Leaks
The Problem:
If you’ve noticed water stains on your walls or ceiling near the fireplace, chances are your chimney is leaking. Causes may include a damaged chimney cap, cracked crown, or deteriorating flashing.
How We Fix It:
- Chimney Cap Repair or Replacement: We install high-quality caps to prevent water, animals, and debris from entering.
- Crown Sealing: We repair or replace the chimney crown and apply waterproof sealant to stop leaks at the top.
- Flashing Repair: We replace rusted or cracked flashing at the chimney base to ensure a tight seal against your roof.
4. Creosote Buildup
The Problem:
Creosote is a highly flammable substance that builds up inside chimneys when wood is burned. Too much creosote puts your home at risk of a chimney fire.
What We Do:
We recommend annual chimney cleaning and inspections. Our team safely removes creosote buildup and checks for blockages, ensuring your chimney is clean and safe to use year-round.
5. Chimney Leaning or Tilting
The Problem:
In some cases, a chimney may begin to lean due to poor footing, soil erosion, or extensive water damage. This is not just a cosmetic issue — it’s a major structural concern.
Our Fix:
We assess the foundation and structure to determine the cause, then rebuild or reinforce the chimney as needed. This often includes adding proper drainage and support to prevent the problem from recurring.
6. Animal and Debris Blockages
The Problem:
Birds, squirrels, and even raccoons love making chimneys their homes — and it only takes a few twigs to cause a dangerous blockage.
How We Solve It:
We remove any debris or nests safely, then install a chimney cap with a built-in screen to keep wildlife and leaves out for good.
