Question: Does my chimney need repointing? (Lake Forest, IL)

Answer:

Repointing your chimney involves renewing the external part of the mortar joints between the bricks. Over time, weather and other environmental factors can cause the mortar to deteriorate, leading to gaps and weakened joints. Here are signs that your chimney may need repointing:

1. Visible Cracks in Mortar: If you notice cracks, gaps, or crumbling mortar between the bricks, it’s a clear sign that repointing is needed. This is especially important in Lake Forest, IL, where fluctuating weather can accelerate mortar deterioration.
2. Loose or Missing Bricks: If bricks are loose, missing, or have shifted, this indicates that the mortar has lost its ability to hold them in place securely.
3. Water Infiltration: If you’re experiencing leaks or notice water stains inside your home near the chimney, it could be due to compromised mortar joints allowing water to penetrate the structure.
4. Efflorescence: This is a white, powdery residue that appears on the surface of the bricks. It’s caused by water pulling salts from the mortar. While it’s not harmful in itself, it signals moisture issues that may require repointing to resolve.
5. Spalling Bricks: Spalling occurs when water penetrates the brick and, upon freezing, causes the brick surface to peel, flake, or pop out. This is often due to damaged mortar allowing water infiltration.

If your chimney shows any of these signs, it’s likely time for repointing. Repointing not only restores the structural integrity of the chimney but also enhances its appearance and prevents further water damage.
