Floor framing damaged by weather during construction

Acceptable Performance/Condition

The joists and subfloor shall be sound and free from damage caused by weathering and must provide a suitable base for finished flooring.


One-Year Work and Materials
Five-Year Major Structural Defect


Joists and subfloors damaged by weathering to the extent that they cannot carry the anticipated loads or are made unsuitable for finished flooring shall be repaired.


Composite panels such as oriented strandboard and plywood used for subfloors and webs of manufactured joists require more protection than solid-sawn lumber and can swell or delaminate if saturated over lengthy periods. Discolouration alone does not necessarily indicate a warrantable condition.
