  • Allergic reactions
  • Infections

Check the following areas for mould stains: Under the sink Around wall tiles Along caulking Behind wallpaper Under carpeting Many remodelling homeowners may even find mould behind tiles and under the tub. Consequently, you should leave no corner or crevice unsearched when you inspect for mould. Once you find mould, you can take stepsto remove it.

  • Open windows to dry the mould and provide fresh air
  • Seal the doors and HVAC ventsto prevent the transfer of sporesto other areas of the house

How to Prevent Mould Growth

Once you've removed the mould and restored your home to its pristine condition, you'll want to take extra precautionsto avoid future reappearances.

1. Avoid and Remove Moisture

You probably know that mould needs moisture and humidity to thrive-that's why the bathroom tendsto grow the most mould. Fortunately, you can cut some of the moisture by using a squeegee to remove water from walls, mirrors and the ceiling after a
shower. Also, run the bathroom fans during your shower or bath and for 30 minutes after. Allow natural sunlight to flood the room to help evaporate the water vapour. To prevent mould growth house-wide, keep an eye on humidity levels. A good range is between 30 and 50%.

2. Eliminate Hiding Places

The fewer items you have in your bathtub or shower, the better. Shampoo and conditioner bottles, washcloths, sponges, razors
and body washes may become a hiding place for mould to grow.
If you must keep these itemsin the bath, dry them after every shower or bath.

3. Use Sealants

Waterproofing plays a significant role in preventing mould growth. Hire a professional to caulk along the edges of the tub and toseal the grout between tiles. This will stop water from building up in areas you don't immediately see.

With these steps, you can create a safe and healthy environment for you and your loved ones. If you have further questions about waterproofing and sealing your bathroom, consider asking a professional sealer for advice. He or she can determine the most cost efficient techniques and solutionsfor preventing mould growth.
