Stucco & Lath Inspection
Stucco is one of the most common exterior cladding systems in Florida and one of the most frequently deficient. Problems with lath installation or stucco application that go undetected at this phase become water intrusion, cracking, and costly remediation after the home is occupied.
Lath Installation — ASTM C 1063 Complianc
Metal lath installation is verified against ASTM C 1063. Common deficiencies include improper lath overlap at seams and corners, incorrect fastener spacing and penetration depth, missing or improperly positioned weep screed at the base of wall assemblies, and inadequate lath support at openings. Weep screed placement is particularly critical in Florida — it must be positioned to allow moisture to exit the wall cavity.
Stucco Application — ASTM C 926 Compliance
Stucco application is verified against ASTM C 926. This includes scratch coat thickness and consistency, proper curing time between coats, control joint placement and spacing, and integration with window and door flashing at all penetrations.
Why this Phase Matters
Once the finish coat is applied and paint goes on, deficiencies in the lath and base coats are completely hidden. Water intrusion through a compromised stucco system is one of the most expensive repairs a homeowner can face. An independent inspection at this phase provides documented protection.
