Facade sealants: an early inspection guide

Start with movement, adhesion, and exposure

Sealants are designed to accommodate movement at joints, but their performance depends on joint geometry, adhesion, backing material, and exposure. Early inspection should note cracking, cohesive splitting, edge separation, staining, and areas where water can sit at the joint.

Inspect the interfaces, not only the sealant bead

Review transitions around windows, cladding changes, penetrations, parapets, and drainage details. A visible defect can be a symptom of movement, detailing, or water-management conditions that should be understood before specifying replacement work.
