How Michigan Winters Can Damage Brick and Masonry

How Michigan Winters Can Damage Brick and Masonry

Michigan winters aren’t particularly gentle on the exterior of a home.

Snow and freezing temperatures are obvious concerns, but one of the biggest challenges for brick and masonry is something homeowners may not actually see happening: the repeated freezing and thawing of moisture.

A masonry surface that looks perfectly solid can contain small cracks or openings that allow water to enter. Once temperatures begin fluctuating above and below freezing, those small vulnerabilities can gradually become larger problems.

Understanding how winter affects masonry can help homeowners recognize damage early.

The Freeze-Thaw Cycle

Brick and mortar are porous materials.

Depending on their condition and construction, they can absorb or encounter moisture from rain, melting snow, drainage issues, and other sources.

Problems can develop when temperatures drop.

Water expands as it freezes. Moisture trapped within vulnerable masonry can therefore place additional pressure on the surrounding material.

When temperatures rise, the ice melts. When temperatures drop again, it freezes.

Michigan can experience this cycle repeatedly throughout a single winter.

Over time, existing weaknesses may become progressively worse.

Cracked Mortar Can Allow More Moisture In

Small mortar cracks may not look particularly concerning during warmer weather.

Winter can change that.

A crack provides an opening where water can enter. If that water freezes, expansion can make the opening larger.

As mortar deteriorates, even more moisture may enter during future rain and snow events.

That’s why repairing deteriorating joints can be an important part of protecting exterior masonry.

Brick Faces Can Begin Flaking Away

Freeze-thaw damage can sometimes appear as spalling.

The outer surface of a brick may begin peeling, chipping, or breaking away. In more advanced cases, larger portions of the brick can deteriorate.

Once the protective face has been significantly damaged, the brick may become increasingly vulnerable to weather exposure.

A masonry contractor can determine whether the affected bricks should be replaced and whether there are underlying moisture issues contributing to the damage.

Chimneys Face Significant Exposure

Your chimney is one of the most weather-exposed masonry structures on your home.

It rises above the roofline and can be hit directly by rain, snow, wind, and ice.

The chimney crown, mortar joints, and bricks can all deteriorate over time.

Homeowners should watch for cracked mortar, missing pieces of masonry, loose bricks, damaged crowns, and other visible changes.

Catching deterioration earlier can make a substantial difference in the scope of the repair.

Porches and Steps Can Develop Problems Too

Brick porches and masonry steps are also exposed to Michigan weather.

In addition to precipitation and temperature changes, these surfaces experience foot traffic and may encounter snow removal products and other environmental conditions.

Cracked joints, loose masonry, shifting bricks, or deteriorated surfaces can affect both appearance and usability.

If masonry steps begin moving or deteriorating, professional evaluation is particularly important.

Spring Is a Good Time to Inspect Your Masonry

After months of winter weather, take a walk around your property and look closely at exterior masonry.

Look for changes that weren’t present before winter.

You may notice fresh cracks, missing mortar, flaking brick surfaces, movement around steps, or deterioration around a chimney.

Early identification gives homeowners an opportunity to address damage before another winter puts the masonry through additional freeze-thaw cycles.
