Mould on glass


Listed under: Interior, glass, windows, moisture, mould

Cause

High moisture levels

Repair

  • avoid using unflued gas heaters and avoid drying laundry inside – these add a lot of moisture to the air

  • opening windows for at least 10 minutes every day can make a difference to indoor air quality

  • increase the amount of ventilation provided. In particular, add a rangehood over the kitchen stove and an exhaust vent near the shower in the bathroom, both vented to remove steam to outside the house.

  • an alternative to reduce bathroom steam is to fit a proprietary acrylic dome over the shower to keep the steam inside

  • check that there is insulation in the ceiling space and under the floor. If not, add insulation. See the website www.level.org.nz for more details. There may be funding available to help with the cost
