For property owners and managers, deciding how and when to address aging terra cotta can be overwhelming. You want solutions that protect your investment without unnecessary headaches or hidden risks.

Every effective repair plan is bolstered by ongoing maintenance:

• Regular inspections catch developing issues early and protect public safety.
• Maintenance programs typically include mortar repointing, sealant replacement, crack repair, pinning, and cleaning.
• Minimal or delayed intervention can result in more frequent, invasive, and expensive repairs over time.

Why Terra Cotta Needs Expert Attention

Have you noticed cracks, discoloration, or loose pieces on your building’s terra cotta façade and wondered what it means for your property’s safety and value? 

Are you concerned about the costs, disruption, and long-term effectiveness of repair options? 

Architectural terra cotta has stood the test of time due to its durability and design flexibility but is susceptible to unique forms of distress. 

Common issues include moisture penetration, corrosion of metal anchors, cracking from building and façade movements, and spalling or loss of glazed finishes. Many of these problems stem from discontinuous support methods and natural aging.

Engineered Repair Approaches

A structural/building envelope engineering firm can address terra cotta issues using a range of strategies including:

• Repairs: If cracks result from unaccommodated movement or frame shrinkage, engineers may route and seal cracks, sometimes adding supplemental anchors. The material used—flexible sealant or rigid mortar—depends on whether cracks are cyclical or static. However, if steel corrosion is involved, superficial repairs may only delay further deterioration, and more substantial action is required.
• Mortar Joint Repointing: Water infiltration is often minimized by repointing mortar joints between terra cotta units, a process best handled without sealants (except for upward-facing joints) to avoid trapping moisture and exacerbating decay.
