Saint Paul’s Mortar Emergency: Why 2025’s Temperature Extremes Are Making Tuckpointing More Critical Than Ever

If you’re a homeowner in Saint Paul, Minnesota, your chimney’s mortar joints are under assault. The Twin Cities has the coldest average temperature of any major metropolitan area in the nation, with winter temperatures colder than any other major metropolitan area in the continental United States. But it’s not just the cold that’s the problem—it’s the dramatic temperature swings that are wreaking havoc on masonry structures throughout the region.

The Perfect Storm: Why Saint Paul’s Climate Is Devastating for Mortar

In Saint Paul, temperatures typically vary from 9°F to 83°F and are rarely below -10°F or above 91°F. This extreme range creates what masonry experts call a “freeze-thaw emergency.” Minnesota winter temperatures are famous for freeze-thaw activity. When water seeps into cracks in your masonry and freezes, it expands.

The science behind the damage is straightforward but devastating. Bricks, and especially the mortar between your bricks, is porous. When it gets wet, water can collect in the tiny air pockets within it. And when moisture gets into those pockets the universal solvent we call water begins to weaken the mortar. When cold weather rolls around the tiny bits of water trapped in your mortar will freeze. When water freezes, it naturally expands. The size of the water will literally get bigger, putting pressure on the bricks and making any gaps even bigger.

2025: A Year of Weather Extremes

Weather forecasters are predicting that 2025 will bring particularly challenging conditions for Minnesota homeowners. Winter temperatures will be above normal, with the coldest periods in much of December, early and late January, and early February. Precipitation and snowfall will be below normal. While this might sound like good news, it actually creates more dangerous conditions for masonry structures.

Above-normal winter temperatures mean more frequent freeze-thaw cycles—the most destructive force your chimney can face. Instead of staying consistently frozen, your mortar joints will repeatedly freeze and thaw, each cycle expanding existing cracks and creating new ones.

The Cascading Effect of Mortar Failure

Freezing weather makes mortar joints erode and crack. When that occurs, water can freely enter the building and cause additional damage. This isn’t just a cosmetic issue—it’s a structural emergency waiting to happen.

Minnesota winters create intense freeze-thaw cycles that are detrimental to chimney brick and stone mortar work. With each rain or snowfall chimneys are exposed to water which works into hairline cracks in the surface. When that water freezes it expands, creating a slightly larger place for water to find during the next precipitation event.

The damage compounds rapidly. Even small cracks become expensive structural damage when exposed to Minneapolis winters or Wisconsin snow. What starts as minor mortar deterioration can quickly escalate into major structural issues, including:

• Water infiltration leading to interior damage
• Brick spalling and deterioration
• Structural instability
• Decreased property value
• Safety hazards

Why Professional Tuckpointing Is Your Best Defense

Properly sealed mortar joints prevent water penetration and moisture buildup within the masonry. This protection is crucial in climates prone to freeze-thaw cycles, as water ingress can lead to cracking, spalling, and further deterioration of the bricks or stones. By maintaining tight mortar joints, tuckpointing helps to extend the lifespan of the masonry.

Professional tuckpointing involves carefully removing deteriorated mortar and replacing it with fresh, properly matched material. This isn’t a DIY job—the expertise required to match mortar composition, color, and texture while ensuring proper adhesion and weather resistance requires professional training and experience.

When you see mortar beginning to crumble don’t hesitate to call in a professional to replace it.
