Expert Guide: How to Safely Pressure Wash Your Decking and Why Hiring a Professional is the Best Option

Keeping your decking in great shape is important for any homeowner or property manager. Pressure washing can be a powerful cleaning method, but it comes with its own set of challenges. This guide will walk you through how to safely pressure wash your decking, the risks involved, what tools you need, and why hiring a professional could be the best choice. With the right knowledge, you can protect your investment while keeping your deck looking fresh.

Can I Pressure Wash My Own Decking Safely?

Pressure washing is an effective way to eliminate dirt, algae, and other buildup from your decking. But can you do this safely? Yes, but only if you follow proper safety measures and use the right tools.

When planning to pressure wash, first consider your decking material. Different materials, like wood, composite, and PVC, require specific techniques to avoid damage. For instance, a recent study showed that using too much pressure on wood decking can cause splintering in up to 30% of cases.

To help you tackle this task safely, here are some practical tips:

• Adjust Pressure Settings: Various decking materials can handle different pressure levels. For wood, a pressure setting around 1200 to 1500 PSI is typically safe. Starting low and adjusting gradually helps prevent damage.

  
  

• Choose the Right Nozzle: Nozzles vary in spray angles. A 25-degree nozzle generally works well for wood. However, the 40-degree nozzle may be more appropriate for softer composite materials. Do not use a Turbo Nozzle!

  
  

• Keep a Safe Distance: Maintain around 12-18 inches between the nozzle and the surface. This distance keeps the blast gentle enough to avoid harm.

  
  

• Test a Small Area First: Always try out the pressure washer on a less visible area of your deck. This small test can help prevent noticeable damage or unwanted results.

  
  

These precautions can help you enjoy the benefits of pressure washing while minimizing potential risks.

Will It Cause Damage?

Using pressure washing improperly can lead to several issues. Understanding these risks is crucial before you start washing your deck:

• Splintering or Gouging: High pressure can splinter wood or gouge softer materials. Estimates show that around 20% of DIY pressure washing jobs result in these kinds of damages.

  
  

• Loose Boards: Forceful water streams may loosen boards, especially if they were not installed properly. This can create safety hazards for anyone using the deck.

  
  

• Chemical Damage: If you plan to use cleaning agents, make sure they are suitable for your specific decking material. Using harsh chemicals can strip away protective finishes or alter colours.

  
  

• Mould or Mildew Growth: If your deck does not dry completely after washing, it can be prone to mould or mildew. Statistics indicate that untreated areas can grow mould within just 48 hours.

  
  

Investing time in research and preparation is vital to accomplish a successful pressure wash without causing damage.

Why Choose a Professional Instead?

While pressure washing might seem easy, hiring a professional can save you time and hassle. Here are some reasons why working with a pro can be beneficial:

Expertise and Experience

Professionals bring years of experience and knowledge about various decking materials. They can accurately assess your decking, select the appropriate pressure settings, and apply the best techniques for optimal results.

High-Quality Equipment

Professionals use industrial-grade pressure washers that deliver better results compared to standard consumer models. For example, they often use machines that can reach pressures above 3000 PSI, ensuring effective cleaning without damaging the surface.

Time-Saving

Washing a large area or a complicated layout can take a significant amount of time. Professionals can complete the job faster, allowing you to spend your time on other important tasks.

Post-Cleaning Treatments

Often, professional services include additional treatments like applying wood preservatives and anti-slip coatings after washing. These treatments can extend the life of your decking and improve safety.

Safety Assurance

Safety is incredibly important, especially with high-powered equipment. Hiring a professional mitigates risks, preventing potential accidents and injuries during the cleaning process.

What Tools Do I Need?

If you choose the DIY route, you'll need these key tools:

1. Pressure Washer: Look for a model with adjustable pressure settings. Electric pressure washers often work well for home use, especially those that deliver 1400-2000 PSI.

   
   

2. Nozzles: Invest in a range of nozzles to customize the spray for different surfaces.

   
   

3. Cleaning Solutions: Use eco-friendly detergents that are safe for your decking type to boost clean results.

   
   

4. Protective Gear: Wear safety goggles, gloves, and slip-resistant footwear to guard against flying debris and slippery surfaces.

   
   

5. Extension Cords and Hoses: Make sure you have adequate lengths to reach all areas of your deck.

   
   

6. Brushes: A stiff brush helps tackle stubborn stains that pressure washing alone might not remove.

   
   

7. Tarps and Rags: Use tarps to cover nearby plants or furniture and rags to catch excess water and mess.

   
   

Understanding how to use each of these tools properly is just as important as having them.

Will My Insurance Cover It if I Damage My Decking?

A crucial question when considering DIY tasks is whether your insurance will cover any damage that may occur. Many homeowner’s policies generally include liability coverage for accidents stemming from DIY work, but specifics can vary.

Important Points to Consider:

• Check Your Policy: Review your home insurance policy to determine if it covers damage while pressure washing.

  
  

• Liability Coverage: If you accidentally damage a neighbour's property, liability insurance can help cover those costs.

  
  

• Excess: Keep in mind that even if your insurance covers damage, you may still be responsible for an Excess, which could lessen your financial relief.

  
  

• Professional Services Liability: If you hire a professional, they usually have their liability insurance, which protects against damages they might cause during the job.

  
  

Before you pressure wash, consulting your insurance company to clarify your coverage and any potential liabilities is a wise step.

Why It’s Better to Hire a Professional

Opting to hire professionals for pressure washing provides unique benefits that DIY efforts cannot match:
