Signs of Wet Basements in Oshawa

There are several warning signs that show you may have leaks and water infiltration in your basement. The best course of action is to act on those warning signs before they become much more serious. Some of the most common signs include:

  • Damp Odours – Moisture and mould growth releases a musty/earthy odour.
  • Water Stains – Stains on cement walls or drywall that are yellowish or brownish suggest water infiltration.
  • Visible Mould – Mould comes hand in hand with the presence of water or high humidity.
  • Cracks – All cracks in walls and the floor, from hairline to wider, need to be addressed as they may indicate a hidden, more serious problem.
  • Efflorescence – This comes from water seepage that leaves behind minerals in the form of a chalky residue.
