Where can mold be found?

Many renovation projects will involve mold. Whether it started out as cleanup from a flood or the mold was found along the way, mold needs to be dealt with. If you're not sure how to handle a project involving mold, consider hiring a professional.

Mold typically flourishes in moist, dark areas. It can grow in bathrooms, basements, attics and even inside the catch trays of refrigerators and air conditioners. Mold can irritate individuals with seasonal allergies and other respiratory conditions, and act as a potential trigger for asthma attacks.

If I find mold should I have it tested?

Probably not, mold testing is not usually recommended. Testing is expensive and provides very little useful information. If you can see mold or smell mold, there's mold. All molds should be treated the same in terms of cleaning and removal and the time, money and energy devoted to testing are better spent removing the mold. Even if testing is done, there are no standards to determine if the types of mold or the concentration, will cause an adverse reaction.

What you can do...
  • Use a hygrometer to monitor the relative humidity level in your home. Typically, it's recommended that it should be between 35 and 55%. Dehumidifiers can be used to lower humidity levels that are above this range.
  • Encourage the use of exhaust fans in our bathrooms
  • Repair roof and plumbing leaks as soon as they are noticed
  • Vent clothes dryers and exhaust fans outside
  • Make sure that basements and crawlspaces are kept dry through the use of sump pumps and dehumidifiers
  • If you have flood or other water damage, take care of it before mold has a chance to grow.
