Parapet Brick Deterioration: When Repairs Are Needed

Brick and mortar deterioration is the most common parapet problem. Here's what to look for and when repairs become necessary.

Types of Deterioration

• Spalling: Bricks flaking or breaking off due to moisture and freeze-thaw cycles
• Mortar failure: Crumbling joints that weaken the wall structure
• Cracks: Structural cracks indicate movement or load problems
• Efflorescence: White salt deposits showing moisture penetration
• Bulging: Wall tilting outward — serious structural problem

When Repairs Are Necessary

Repairs should be done when:

• Inspector recommends it in the report
• Deterioration is visible or worsening year-to-year
• Mortar joints are significantly deteriorated
• Bricks are loose or falling
• Water is leaking inside the building

Typical Repair Costs

• Repointing (mortar): $50–$150 per linear foot
• Brick replacement: $100–$300 per brick
• Flashing repair: $500–$2,000+
• Full parapet rebuild: $1,000–$5,000+ depending on size

Preventative Maintenance

Regular inspections catch problems early when repairs are cheaper. Delaying repairs can lead to structural damage requiring major (expensive) reconstruction.
