Mould

Mould needs air with at least 60% moisture to grow and when it goes on detected, it can create an environmental health problem for people living here in Ottawa who are sensitive to airborne allergens. Along with health issues mould is a sign of severe dampness, which can cause structural damage to the dwelling be it a residential or commercial building. This is particularly important with a residential home because of the amount of wood involved.

Damp wood will rot and along with that accumulate mould and mildew. In certain cases here in Ottawa, depending on the quality of the concrete used to pour a patio or basement and footers, water can seep in through the porous concrete where mould and mildew can accumulate and create the same issue present with wet wood. This is why it is important to seal a concrete slab designated for carpet coverage.
