How to Get Rid of Mould On Windows

Mould can be an unwelcome guest in any home, and windows are a common target. Not only is mould on windows unsightly, but it can also lower air quality, trigger allergies, and respiratory problems. Fortunately, with a little know-how, you can effectively remove mould from your windows and prevent it from returning.

In this blog post, we’ll guide you through the process of removing mold from your windows and provide some helpful tips to keep it at bay.

What is Mould?

Mould is a type of fungus that grows in damp or humid environments. It reproduces by releasing mold spores into the air, which can then land on other surfaces and germinate. Mould can come in various colours, including black, green, brown, and white.

Why Does Mould Grow on Windows?

The area around windows is particularly susceptible to mould growth due to several factors:

• Condensation: When warm, humid air inside your home comes into contact with the cooler surface of the window pane, condensation forms. This creates an environment with excess moisture, perfect for mold on windows to grow.
• Poor Ventilation: Inadequate air circulation around windows can trap moisture, further encouraging mould development.
• Organic Materials: Window mould thrives on organic materials. Caulk or wooden window frames can provide a food source for mould spores.

Signs of Mould on Window Sill

Mould on windows can appear in various forms, so it’s important to be able to identify it. Here are some signs to watch out for:

• Visible Mould Growth: The most obvious sign is the presence of black, green, brown, or white patches of mold on window frames, sills, or even the glass itself.
• Musty Odors: Mould, especially black mold on window sill often produces a musty or earthy smell, which can be a telltale sign of its presence.
• Health Concerns: While not all mould is harmful, exposure to certain types can cause respiratory problems, allergies, and irritation of the eyes and skin. If you’re experiencing health problems and suspect a significant mould infestation, it’s best to consult a professional mould remediation company.

Materials You’ll Need

Before you start removing the mold on window sill, here’s what you’ll need:

• Safety Gear: Protect yourself by wearing rubber gloves, eye protection, and a respirator (preferably N-95 rated).
• Cleaning Solutions:
  ○

  White Vinegar: This natural disinfectant is effective against most household mold strains. Mix equal parts white vinegar and water in a spray bottle.
  ○

  Hydrogen Peroxide (3% solution): A gentler alternative to bleach; it effectively removes mold without emitting harsh fumes.
  ○

  Commercial Mould Remover: For stubborn mould or larger areas, consider using a commercially available mold remover. Always follow the manufacturer’s instructions carefully.

• Cleaning Tools:

• ○

  Spray bottle: To apply the cleaning solution.
  ○

  Scrub brush: For removing stubborn mold growth.
  ○

  Microfibre cloths: For cleaning and drying the window area.
  ○

  Drop cloths: To protect your floor and surrounding areas from drips.

How to Get Rid of Mould on Window Sills in 5 Easy Steps

1. Preparation

Open windows to ensure proper ventilation and wear your safety gear. Remove any curtains or blinds that might obstruct the cleaning process. Lay down drop cloths to protect your floor and surrounding areas.

2. Apply Cleaning Solution

Spray the affected area thoroughly with your chosen cleaning solution. Allow the solution to sit for 10-15 minutes to loosen the mould spores.

3. Scrubbing

Use a stiff-bristled scrub brush to tackle any stubborn growth of mould on window sill. Be gentle but thorough, ensuring you remove all visible mould. Avoid using abrasive scrubbers on window frames, as they can scratch the surface.

4. Rinsing

Rinse the entire area with clean water to remove the cleaning solution and dead mould spores.

5. Drying

Thoroughly dry the window frame, sill, and surrounding areas with clean microfiber cloths. It’s crucial to remove all moisture to prevent mould from returning. You can also use a fan to accelerate the drying process.

How To Prevent Mould On Window Sills

Mould thrives in damp environments, and window sills are prime targets due to condensation and organic materials. Here’s how to keep them mould-free:

Boost Ventilation

Open windows regularly, especially during humid weather, and use exhaust fans in kitchens and bathrooms to promote air circulation and remove moisture. Dehumidifiers can further regulate humidity levels in your home.

Clean Up Spills

Don’t let water linger on window sills. It can cause aluminum window frames to rust and a wooden window frame to bloat and rot. Wipe up spills and drips promptly with a dry cloth to prevent moisture buildup.

Check Seals

Regularly inspect window seals for cracks or gaps that allow moisture to enter. If damaged, consider getting them replaced by a professional to prevent mold growth preemptively.

Clean Drains

Keep window sills and weep holes (small drainage holes on the exterior window sill) clear of debris to ensure proper drainage of any accumulated water.

Plant Placement

Avoid keeping moisture-loving plants directly on window sills, as they can contribute to humidity. Place them in well-ventilated locations away from windows and place plants that don’t require constant watering like succulents instead.

Double-Pane Windows

Consider investing in double-paned windows when replacing windows. These high-efficiency windows create an insulating barrier that prevents condensation on the inner pane.

Sunlight Exposure

Open curtains and blinds during the day to allow sunlight to reach window sills, naturally drying them out and hindering the growth of mould on windows.
