Is mould affecting your home and health?

Is mould affecting your home and health?

All homes can be susceptible to mould growth. In fact, mould could be present without you even realizing it. Exposure can cause an array of health issues from coughing, wheezing, headache and nausea to nasal stuffiness, sore throat, skin irritation, fatigue and more.

Virtually anywhere can be a breeding ground for mould, as long as there's air, moisture, organic material (a food source) and adequate temperatures––between 40˚F (5˚C) and 104˚F (40˚C). It's most commonly found in areas where moisture levels tend to be higher, like basements, kitchens, bathrooms or near water leaks in roofs, attics, walls, and pipes.

Identifying a mould problem can be a challenge, because mold can grow in hidden areas such as behind walls. Signs include discoloration of indoor surfaces, dark spots or patches. Musty odours can also be an indication that harmful mould is present.

Swift action is necessary to ensure your health and prevent mould from damaging your home. Start by containing it, then begin remediation. Resolving small amounts of surface mould can be a simple to moderate DIY project, but large areas should be left to professionals. Finally, take preventative measures to keep mould away for good.

Several mould prevention strategies can safeguard your home and health. When building, renovating or remediating an existing mould issue, it's wise to carefully consider building materials, especially within your wall assembly, which is a common area for mould growth. Certain types of insulation are especially vulnerable. Only use insulation with high drying potential, made from inorganic material that will not promote the growth of mould when exposed to moisture. I recommend a stone wool insulation, like Roxul Comfortbatt and Safe 'n' Sound. It's Greenguard certified to the highest standard for indoor air quality. Mould-resistant wood, drywall, caulking, paint, and other moisture management materials are also available.

Always be sure to immediately dry any areas in your home that get wet. Prevent moisture with proper ventilation. Monitor indoor humidity, aiming for 30 to 50 per cent. Direct water away from your home and its foundation. Keep gutters clear and stay on top of roof maintenance and repairs. Improve air flow in your home.

Finally, inspect your home regularly to ensure your family breathes easy.
