Atlanta Winter Storm Warning: How Ice & Freezing Temperatures Damage Brick, Chimneys & Masonry

Why Winter Storms Are So Hard on Brick & Masonry in Georgia

Atlanta’s biggest masonry risk isn’t just freezing — it’s freeze-thaw cycles.

What Is a Freeze-Thaw Cycle?

A freeze-thaw cycle happens when:

1. Water enters small cracks or mortar joints
2. Temperatures drop below freezing
3. The water expands as it freezes
4. Temperatures rise and the ice melts
5. The process repeats

Each cycle widens cracks, weakens mortar, and shifts brickwork. Unlike northern states, Georgia masonry:

• Often isn’t designed for repeated freezes
• Uses older mortar mixes that absorb moisture
• Is exposed to rapid temperature swings

This makes Atlanta homes especially vulnerable during winter storms.

Hidden Masonry Damage Homeowners Often Miss After a Freeze

Not all damage is obvious right away. In fact, many masonry problems show up days or weeks after the storm, once temperatures rise.

Common Hidden Issues Include:

• Hairline cracks in mortar joints
• Loose or hollow-sounding bricks
• Subtle leaning in brick mailboxes or columns
• Chimney mortar separating from brick
• Water trapped behind retaining walls
• Brick faces beginning to flake or crumble

By the time visible damage appears, repairs are often more extensive.

Masonry Areas Most at Risk During Atlanta Winter Storms

Brick Walls & Home Exteriors

Brick absorbs moisture. When that moisture freezes:

• Mortar joints deteriorate
• Brick faces can spall or pop
• Structural stability weakens over time

Chimneys

Chimneys are highly exposed and frequently affected by:

• Cracked mortar
• Loose bricks
• Crown damage
• Poor ventilation caused by shifting masonry

A damaged chimney can become a serious safety hazard.

Brick Mailboxes

Brick mailboxes are especially vulnerable because:

• They’re freestanding
• Water pools at the base
• Ice expansion loosens foundations

Many mailboxes fail after the freeze, not during it.

Retaining Walls

Water trapped behind retaining walls expands when frozen, increasing pressure and causing:

• Bulging
• Cracking
• Partial collapse

This damage is often hidden until soil begins to shift.

Signs You Should Call a Mason After the Storm

Call a professional masonry contractor immediately if you notice:

• Cracks in brick or mortar
• Leaning brick structures
• Loose or missing mortar
• Crumbling brick edges
• Water intrusion near masonry
• Chimney debris in your yard
• HOA notices related to exterior damage

Waiting can turn a minor repair into a full rebuild.

Why Post-Storm Masonry Inspections Matter

A post-storm inspection allows a mason to:

• Identify freeze-related damage early
• Reinforce weakened areas
• Prevent water from re-entering masonry
• Extend the life of brick and stone features
• Save homeowners thousands in future repairs

Most inspections take less than an hour and can uncover issues homeowners wouldn’t spot on their own.

Can Masonry Damage Be Repaired After a Freeze?

Yes — and early repairs are usually:

• Faster
• Less expensive
• Less invasive

Common post-storm masonry repairs include:

• Tuckpointing and repointing mortar
• Brick replacement
• Chimney stabilization
• Brick mailbox repair or rebuilding
• Retaining wall reinforcement
• Brick cleaning to remove moisture-trapping residue
