The Dos and Don’ts of Pressure Cleaning Your Home Exterior

Pressure cleaning is a highly effective way to revitalise your home’s exterior, enhance its curb appeal, and extend the lifespan of various surfaces.

Not only does it increase the market value of your property, but homes with clean exteriors also tend to sell faster than those with dirty or neglected exteriors. Regular pressure cleaning helps prevent the build-up of mould, mildew, dirt, and grime, which could eventually lead to costly repairs. However, it’s essential to do it right, as improper pressure cleaning can damage your property or even cause safety hazards.

This guide will outline the dos and don’ts of pressure cleaning, ensuring that you achieve optimal results without damaging your property.

What is Pressure Cleaning?

Pressure cleaning, also known as pressure washing, uses high-pressure water jets to remove dirt, grime, mould, algae, and other contaminants from various surfaces. It’s commonly used on driveways, patios, decks, fences, exterior walls, and even roofs.

The power of the water breaks down debris more effectively than traditional scrubbing or hosing, making it a time-saving and water-efficient cleaning method.

However, the pressure settings must be adjusted according to the type of surface you’re cleaning. Using too much pressure can cause significant damage to softer materials like wood or painted surfaces, while insufficient pressure may not effectively clean the surface.

When done correctly, pressure cleaning can make your home shine and improve the hygiene of your surroundings. But it’s important to understand when, where, and how to apply pressure cleaning for the best results.

What is Home Exterior Cleaning?

Home exterior cleaning refers to the various techniques used to keep the outside of your property clean, well-maintained, and protected from long-term damage caused by pollutants, dirt, mould, and algae.

This includes washing walls, roofs, windows, gutters, driveways, and decks. It’s not just about aesthetics—it’s also about protecting the structure of your home.

Routine exterior cleaning prevents the growth of harmful bacteria, mould, and algae, which can affect the health of your family and reduce the longevity of your property.

Home exterior cleaning can be done manually with brushes and mild detergents, or through more advanced methods like pressure cleaning and soft washing, which are suitable for tougher stains and larger surfaces.

Choosing the right cleaning method depends on the material and the level of dirt build-up.

The Dos of Pressure Cleaning

1. Assess the Surface Before Cleaning

Before you start, take the time to thoroughly inspect the surface you intend to clean. Different materials require different pressure levels.

For instance, delicate materials like wood, paint, and stucco require lower pressure settings to avoid damage, while more durable surfaces like concrete and brick can handle higher pressure. Always assess the condition of the surface and choose the safest cleaning method for each one.

2. Use the Correct Pressure Settings

Pressure washers come with various nozzles and pressure settings, typically measured in PSI (pounds per square inch).

Using the correct pressure setting is crucial to avoid damaging surfaces. Always check the manufacturer’s instructions and use the lowest pressure setting possible for the task at hand. Start with a lower pressure and gradually increase it if necessary.

3. Wear Proper Safety Gear

Pressure washers use high-pressure water that can cause severe injuries if handled improperly. Always wear appropriate safety gear when operating a pressure washer.

This includes:

• Safety goggles to protect your eyes from flying debris and water.
• Rubber gloves to protect your hands from high-pressure water and chemicals.
• Waterproof boots to avoid slipping in wet conditions.
• Long-sleeved clothing to shield your skin from water and debris.
  
  

Additionally, ensure that the area is safe.

Keep children, pets, and bystanders well away from the work zone to avoid accidents. If you’re using an electric pressure washer, consider using a ground fault circuit interrupter (GFCI) for added electrical safety.

4. Test on a Small Area First

Before committing to cleaning a large area, test the pressure washer on a small, inconspicuous section of the surface. This is especially important for painted surfaces or older materials, which may be more fragile.

Testing allows you to determine how the surface reacts to the pressure and ensures you don’t inadvertently cause damage. You can also check if any detergents you’re using cause discolouration or residue.

5. Use Eco-Friendly Detergents

When cleaning surfaces like driveways, decks, or roofs, you may need to use cleaning solutions to remove stubborn stains, mould, or algae.

Always opt for eco-friendly detergents that are biodegradable and safe for plants, pets, and the environment. Harsh chemicals can damage your garden, leach into stormwater drains, and harm wildlife. Be sure to rinse thoroughly after applying any detergent.

If you’re unsure about which product to use, consult with professional cleaners who can recommend safe, effective options.

The Don’ts of Pressure Cleaning

1. Don’t Use Excessive Pressure

It’s a common misconception that more pressure leads to better cleaning.

In fact, using too much pressure can cause irreparable damage to your home’s surfaces. High-pressure water can strip paint, crack windows, gouge wood, and cause other forms of damage. Always use the lowest pressure setting necessary to get the job done.

Check the manufacturer’s guidelines for pressure recommendations and adjust accordingly.

2. Don’t Skip Covering Delicate Areas

Before starting, cover or shield areas that could be damaged by high-pressure water. These include:

• Electrical outlets and outdoor lights
• Windows
• Delicate landscaping

Cover these areas with plastic sheeting or tarps to prevent water from seeping in and causing damage. If necessary, move fragile items like potted plants or outdoor furniture away from the area to avoid damage.

3. Don’t Ignore Manufacturer Safety Guidelines

Each pressure washer model is different, and it’s essential to follow the safety guidelines provided by the manufacturer.

Misusing your pressure washer can result in accidents, poor performance, or even equipment damage. Read the user manual carefully and adhere to instructions regarding fuel types, hose connections, pressure limits, and recommended nozzles.

Not following these guidelines can void warranties and compromise your safety.

4. Don’t Hesitate to Call a Professional

While DIY pressure cleaning can be effective, not every cleaning job should be attempted on your own. If you’re dealing with delicate surfaces, are unsure about the correct pressure settings, or need a more thorough clean, it’s wise to call in a professional.
