What is Mould and Why is it a Problem?
Mould is a type of fungus that grows in damp environments. It produces tiny spores that float in the air. When these spores land on a wet surface, they can begin growing new mould. Mould causes problems because it can trigger allergic reactions and even asthma attacks in some people. Prolonged exposure to high levels of mould may also cause respiratory infections.
In addition, mould can damage materials in your home. It feeds on organic materials like wood, paper, and fabrics. Over time, a mould infestation can weaken floors, walls, and ceilings.
Some of the most common places to find mould in a home include:
- Bathrooms
- Basements
- Kitchens
- Attics
- Crawl spaces
Anywhere moisture accumulates can be susceptible to mould growth. That’s why controlling moisture is the number one defense against mould.
How to Prevent Mould Growth in Your Home
Here are some tips to help prevent mould from becoming a problem in your home:
Control Moisture
Moisture is the main factor that allows mould to grow. Here are some ways to control moisture in your home:
- Use exhaust fans or open windows when cooking, showering, or doing other activities that produce moisture.
- Make sure clothes dryers are properly vented outside.
- Fix any leaks in roofs, windows, or plumbing immediately.
- Use a dehumidifier to maintain low humidity levels (between 30-50%).
- Increase ventilation in damp areas like basements and crawlspaces.
Clean and Disinfect Regularly
- Clean bathrooms, kitchens, and other prone areas with mold-killing products weekly.
- Use a solution of 1 cup bleach to 1 gallon of water to kill and prevent mold.
- Make sure to sanitize places like shower curtains, grout, and windowsills where mold likes to grow.
Be Careful With Carpets and Furniture
- Avoid putting carpets in rooms prone to moisture like basements.
- Clean carpets and upholstered furniture regularly to prevent mold growth.
- Make sure furniture isn’t pushed up against exterior walls where condensation can form.
Maintain Your Home’s Structure
- Clean out gutters and make sure downspouts direct water away from your home’s foundation.
- Make sure your roof is in good repair with no missing shingles or leaks.
- Insulate exterior walls to prevent condensation from forming on cold surfaces.
- Seal any cracks and openings throughout your home’s exterior.
By controlling moisture and properly maintaining your home, you can stop mold in its tracks. Be diligent in following these preventative steps.
How to Get Rid of Existing Mold
If you already see some mold growing in your home, you’ll need to take steps to get rid of it. Here is an effective process:
Step 1: Protect Yourself
- Wear goggles, gloves, and a N95 respirator mask when working with mold.
- Isolate the affected area by sealing off doorways with plastic sheeting.
- Open windows and use fans to ventilate the area.
Step 2: Identify and Assess the Affected Area
- Look for signs of mold like musty odors, spots, or cottony growths.
- Determine how much material is infected. Is it just surface mold or has it permeated deeper materials?
Step 3: Clean and Disinfect
- Scrub visible mold off hard surfaces with detergent and water.
- Use mold killing solutions or bleach to disinfect the area.
- Note: Always check that the affected material can withstand bleaches or chemicals before using them.
Step 4: Remove Damaged Material
- Remove and discard porous materials like drywall, carpeting, or insulation if they are moldy.
- Wear proper protective gear while removing materials to avoid exposure.
Step 5: Dry the Area
- Use fans, heaters, or dehumidifiers to fully dry out the affected area.
- Mold cannot grow without moisture present.
Step 6: Revisit and Monitor
- Check the area periodically to make sure mold does not return.
- If it does, repeat cleaning and take additional steps to eliminate moisture sources.
With diligence and the proper safety precautions, you can banish mold from your home for good. Don’t let it take root in the first place by staying on top of moisture control and prevention.
