Preparing Your Home’s Masonry for Winter: A Fall Maintenance Checklist

As temperatures drop in Duluth and the snow starts to fall, your home’s masonry surfaces—brick, stone, and concrete—face a tough season ahead. Freeze-thaw cycles, moisture buildup, and temperature fluctuations can cause cracks, crumbling mortar, and water intrusion. Taking time this fall to inspect and maintain your masonry can save you from costly repairs come spring.

Here’s a simple checklist to get your home’s masonry winter-ready.

1. Inspect for Cracks and Gaps

Start with a visual inspection of your foundation, chimney, patio, and walkways. Look for cracks, flaking, or crumbling mortar joints. Even small cracks can allow water in, which expands when it freezes, worsening the damage over time. Repairing these issues early helps prevent long-term structural problems.

2. Clean Masonry Surfaces

Dirt, moss, and organic growth hold moisture against masonry surfaces, increasing the risk of freeze-thaw damage. Give patios, walkways, and exterior walls a good cleaning. For chimneys, professional sweeping is recommended before winter use to remove creosote buildup and check for hidden cracks.

3. Repoint Deteriorating Mortar

If you notice loose or missing mortar, tuckpointing is essential before the cold sets in. Repointing replaces damaged mortar and restores the wall’s strength and weather resistance. This step is especially important for chimneys and exterior walls that face strong winds and snow.

4. Seal Masonry Surfaces

Applying a breathable masonry sealer helps protect against moisture penetration without trapping vapor inside. This step is especially beneficial for concrete driveways, patios, and retaining walls, which often bear the brunt of snowmelt and salt exposure.

5. Clear and Reroute Drainage

Ensure gutters, downspouts, and grading around your home are directing water away from your foundation. Poor drainage contributes to foundation cracks and shifting during freeze-thaw cycles. Adding extensions to downspouts can help prevent water from pooling near walls and slabs.

6. Schedule a Professional Inspection

A masonry contractor can identify subtle issues that homeowners might miss—like weakened mortar joints or hidden moisture pockets. An inspection this fall can help you make small fixes now instead of major repairs later.
