Mould growth in your home can be a serious issue, especially in areas with high humidity like North and Central Brisbane. It can lead to health problems, structural damage, and unsightly surfaces. One effective way to tackle and remove mould is by using pressure cleaning. This method is especially popular for homeowners looking to clean outdoor surfaces like walls, driveways, and roofs. In this article, we will explore how pressure cleaning can help eliminate mould, the best practices for its use, and provide expert tips and insights from local professionals in Brisbane.
What Is Mould, and Why Is It a Problem?
Mould is a type of fungus that grows in damp and humid environments. In Brisbane, with its subtropical climate, mould is a common issue, particularly in areas that are shaded or have poor ventilation. The key to mould growth is moisture, and when surfaces remain wet for long periods—due to rain, leaks, or high humidity—mould thrives.
Health Risks
According to the Queensland Health Department, exposure to mould can trigger allergies, asthma, and other respiratory problems, especially in children, the elderly, and those with weakened immune systems. Mould also damages property by degrading building materials, leading to costly repairs.
How Pressure Cleaning Works to Remove Mould
Pressure cleaning, also known as power washing, uses high-pressure water to remove dirt, grime, and contaminants from surfaces. When it comes to mould, pressure cleaning can be particularly effective for removing surface mould on outdoor areas like:
- Roofing materials (tiles, shingles)
- Concrete surfaces (driveways, walkways, patios)
- Fencing and decking
- Exterior walls (brick, render, timber)
The pressure and force of the water, combined with detergents or mould-removal solutions, effectively remove the mould from the surface. Here’s how it works:
- High-pressure water: The pressure from the nozzle forces water into the pores of the surface, dislodging and washing away the mould.
- Mould removal solutions: Many pressure cleaning services use cleaning agents specifically designed to kill mould spores and prevent them from returning.
While pressure cleaning is effective, it’s crucial to follow certain steps and safety protocols to ensure the best results.
Step-by-Step Guide to Removing Mould with Pressure Cleaning
1. Assess the Area
Before starting, identify the extent of the mould problem. For minor surface mould, pressure cleaning is typically sufficient. However, for extensive mould growth, it’s essential to address the root cause, such as water leaks or poor drainage, before cleaning.
2. Choose the Right Pressure Washer
Not all pressure washers are created equal. The type of washer you use depends on the surface you’re cleaning. For mould removal:
- For Concrete/Stone: A high-pressure washer (3000-4000 psi) with a wide nozzle will be effective.
- For Roofing and Delicate Surfaces: Lower pressure (1500-2000 psi) is recommended to avoid damaging tiles or shingles.
3. Use a Mould-Killing Solution
While pressure alone can remove the visible mould, adding a cleaning solution designed to kill mould spores ensures long-lasting results. Look for solutions that contain bleach, hydrogen peroxide, or vinegar, which are effective against mould growth.
4. Apply the Solution
Before starting the pressure washer, apply the mould-removal solution to the affected areas. Allow it to sit for about 10-15 minutes to break down the mould.
5. Pressure Clean the Area
Once the solution has had time to work, start pressure washing the area. Begin from the top of the surface (like the roof) and work your way down to avoid streaks or running the dirt further into the surface.
Safety Tip: Always wear protective goggles, gloves, and clothing to avoid being hit by debris or harmful cleaning solutions.
6. Rinse and Repeat
After pressure cleaning, rinse the area thoroughly to ensure no cleaning solution remains. If necessary, repeat the process for stubborn patches of mould.
Tips for Maintaining a Mould-Free Home
While pressure cleaning is a great way to remove mould, prevention is key to avoiding its return. Here are some tips to keep your home mould-free:
- Ensure Proper Drainage: Ensure gutters are clear, and water drains away from your foundation to prevent moisture accumulation.
- Improve Ventilation: Use exhaust fans, dehumidifiers, and open windows to improve airflow, particularly in areas prone to moisture, such as bathrooms and basements.
- Regular Inspections: Check outdoor surfaces, such as patios and roofs, regularly for signs of mould growth.
