Some squeaking resulting from normal shrinkage of materials after construction is acceptable however; floors shall be reasonably free from squeaks caused by movement in the floor system connections under normal seasonal indoor humidity and loading conditions.

One-Year - Work and Materials · Squeaks resulting from normal shrinkage of materials caused by drying after construction are excluded from the statutory warranty.

Loose connections causing floor squeaks shall be repaired.

Extended low-humidity indoor environments can cause excessive shrinkage in the wood resulting in loose floor connections. Excessive high-humidity indoor environment can cause expansion in the wood resulting in pressure-related floor squeaks. The homeowner must maintain indoor humidity levels to prevent excessive drying or expansion of materials. A permanent squeak-free floor may not be attainable.

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. Seven-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.

Materials that can be significantly damaged by weather should be protected during storage and construction. 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.

The exterior portion of foundation walls exposed to view above grade shall have no holes (including “honeycombing”) larger than 50 mm in diameter or 25 mm deep.

One-Year – Work and Materials

Walls with holes exceeding the acceptable condition shall be repaired.

It is impossible to completely eliminate all surface voids. At the builder’s discretion a brush coat may be applied. The colour and texture of a repaired area may not match the surrounding concrete. See item 1.15 “Brush coating on above grade poured concrete foundation wall is falling off”

Hairline cracks are normal in parged surfaces; parging that is separating from the concrete block base is not acceptable.

The Building Code only requires parging (a cement-based layer) on concrete block foundation walls below grade.

Brush coating, however, is only a cosmetic application over poured concrete foundation walls and is covered by item 1.15 “Brush coating on above grade poured concrete foundation wall is falling off”.

Slight variation in the colour or texture of repaired areas is acceptable
