Pyrite and pyrrhotite

Pyrite is a mineral which is found in stone and produces sulfuric acid when it oxidizes upon contact with humidity and oxygen. When this phenomenon occurs under foundations, it can cause the heaving and cracking of the concrete slab.

Pyrrhotite is a mineral species composed of iron sulfide and is of a bronze yellow color, blackening when exposed to air. When it crystallizes in blades, pyrrhotite can produce cracks in the concrete structures.

You are not or no longer covered by the Guarantee plan for new residential buildings

The guarantee offered by the plan expires five (5) years after the acceptance of your house or condo.

If your house or condo has been built more than 5 years ago, it is no longer covered by the Guarantee plan for new residential buildings. If you try to make a claim with the manager of the plan, he/she will likely give a decision based on the fact that the guarantee has expired.

Even though such a decision may be appealed in arbitration, you may also examine your possible rights of recourse with a legal advisor. Such rights include the possibility of appealing to civil courts.
