Commercial Exterior Cladding Inspection: What Property Managers Should Look For

Cladding failures lead to moisture infiltration and costly interior damage. Here's how to assess your building envelope.

Exterior cladding is the first line of defence against moisture infiltration. When it fails, water enters the building assembly, damaging insulation, structural elements, and interior finishes — often without visible signs until damage is extensive.

Different cladding types require different inspection approaches. Metal panels, EIFS (synthetic stucco), face brick, precast concrete, and glass curtain walls each have specific failure modes and inspection protocols.

Industry Best Practices

EIFS systems are prone to moisture infiltration at penetrations, window perimeters, and at-grade transitions. Probe suspected areas gently — soft substrate behind the exterior coat indicates moisture damage.

Brick facades develop cracks at structural movement points, masonry joint failure, and freeze-thaw spalling. Repointing deteriorated mortar joints and addressing cracks prevents accelerating deterioration.

How D&D Commercial Services Can Help

Metal panel systems fail at fasteners, sealant joints, and panel seams. Rust streaking, discoloration, and panel deflection are visual indicators of developing problems.

Curtain wall systems require specialized inspection. Failed IGU seals (foggy glass), deteriorated perimeter sealants, and structural clip failures are the primary concern areas.

Thermal imaging during heating season identifies heat loss — a reliable indicator of moisture infiltration or insulation failure within the wall assembly. This non-invasive tool supplements visual inspection significantly.
