Efflorescence can occur on concrete and masonry foundation surfaces.

None

The builder is not required to take any action.

Efflorescence is the formation of a typically white crystalline deposit on the surface of concrete or masonry foundation surfaces when moisture evaporates from the surface. Efflorescence can be removed using a stiff bristle brush and water. See Also: 4.17 EFFLORESCENCE (TYPICALLY A WHITE POWDERY FILM) IS PRESENT ON MASONRY EXTERIOR FINISHES

Concrete surfaces shall not disintegrate to the extent that the aggregate is exposed under normal conditions of weathering and use.

One-Year. Work and Materials · Surface deterioration due to owner-applied substances, improper maintenance, or normal wear and tear is excluded from the statutory warranty.

Where defective installation or product is determined, the concrete surface shall be repaired.

Scaling of exterior concrete surfaces including concrete porches, walkways, garage floor slabs, steps (including precast), etc, most often results from salts and de-icers being applied to the concrete surface, e.g. either intentionally for ice melting or unintentionally from road slush deposits. Cleaning salt deposits off concrete surfaces is normal home maintenance. Where repairs are necessary, colour and/or texture may not match the surrounding concrete.

Cracks resulting from normal shrinkage are acceptable; cracks in excess of 6 mm in width are not acceptable.

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

Concrete walls naturally crack during curing due to shrinkage. Where lateral or vertical movement is evident, further investigation may be required. The colour and texture of a repaired area may not match the surrounding concrete. See Also: 1.7 CONCRETE BLOCK FOUNDATION WALL IS CRACKED

Steel angle lintels supporting masonry shall be protected from corrosion, as per the Ontario Building Code. Corrosion protection applied to lintels shall not deteriorate to the extent of exposing the unfinished steel beneath and lintels shall not rust within one year of the date of possession.

One-Year - Work and Materials. Damage resulting from normal wear and tear is not covered by the statutory warranty.

Corrosion protection not meeting the acceptable performance shall be repaired to match the original condition as closely as possible.

Weathering of painted and primed exterior surfaces is normal. The use of factory primer only is acceptable unless otherwise specified in the Agreement of Purchase and Sale. Notes: This Article applies to all conciliations after January 1, 2019.

Vertical mortar joint thickness shall appear uniform when viewed from a distance of no less than 6 m, and shall be 10 mm with a tolerance of -5 mm to +10 mm in accordance with the Building Code.

One-Year - Work and Materials

Masonry with joints not meeting the acceptable condition shall be repaired.

Unintentional Dimensional variations of the courses are affected by the variations in the brick selected and the bond pattern. Non-uniform joints may be a feature of the wall and may be acceptable. Weep holes and/or vent holes are necessary in a masonry wall and shall not be blocked. This does not apply to randomly sized or designed masonry products such as (but not limited to) specialty brick products; tumbled or aged bricks, beveled-edged bricks or cultured stone or stone products.

The building envelope shall be constructed to prevent water entry.

Two-Year - Building Envelope Water Penetration. Two-Year - Cladding Detachment, Displacement or Deterioration. · Water penetration resulting from improper maintenance or normal wear and tear is not covered by the statutory warranty.

Building envelopes not meeting the acceptable condition shall be repaired.

Joints and cracks in exterior wall surfaces and around openings shall be properly sealed to prevent the entry of water. Caulking and sealants deteriorate under normal weather conditions and should be checked regularly. See Also: 1.14 FOUNDATION WALL LEAKS

When viewed from a perpendicular distance of 1,500 mm, painted or finished surfaces shall be free of visible mould and mildew.

One-Year - Work and Materials. · Damage resulting from improper maintenance or normal wear and tear is not covered by the statutory warranty.

Exterior painted surfaces not meeting the acceptable performance shall be repaired.

Mould or mildew is common in the natural environment. It can often form on painted surfaces and can usually be removed during normal home maintenance.
