Cleaning Decks and Fences: Pressure Washing Tips and Techniques in London, Ontario

Wooden decks and fences grace many homes in Ontario, offering spaces for relaxation, entertaining, and privacy. However, as the seasons change, they can quickly become marred by dirt, grime, and the unforgiving elements.

Cleaning these wooden structures is not just about aesthetics; it's essential for maintaining their structural integrity and longevity.

In this guide, we will provide you with expert tips and techniques for safely cleaning wooden decks and fences, offering advice on pressure settings, detergents, and post-washing maintenance to keep your outdoor space looking its best.

Why fence and deck cleaning is crucial for London, Ontario residents

Living in London, Ontario and its neighboring areas means experiencing a range of weather conditions, from humid summers to snowy winters. This climate variation can take a toll on your wooden deck and fence.

Here's why regular cleaning is crucial for residents in the London region:

Weather Challenges: Ontario's weather extremes, including heavy snowfall and summer humidity, can accelerate the wear and tear on wooden surfaces. Cleaning helps mitigate these effects.
Mold and Mildew: The province's humid climate can lead to the growth of mold and mildew, which not only look unsightly but can also compromise the wood's integrity.
Longevity: Regular deck cleaning and maintenance can extend the life of your wooden structures, saving you money on costly repairs or replacements.
Safety: Slippery surfaces caused by mold or algae can be a safety hazard, especially during Ontario's rainy seasons.

Now that you understand the importance of cleaning your wooden deck and fence in London, Ontario, let's delve into the process.

Pressure washing tools and materials

Before you begin, gather the following tools and materials, which are readily available for Ontario residents:

Pressure Washer: Invest in a pressure washer suitable for home use with adjustable pressure settings. A PSI (pounds per square inch) of 1,500 to 2,500 is typically sufficient for wooden surfaces. If you're a starter, you can also hire a pressure washing company in London to make sure everything's done correctly and see how they do it.
Safety Gear: Ensure you have safety glasses, hearing protection, and appropriate clothing to protect yourself during the cleaning process.
Wood-Friendly Detergent: Choose a detergent specifically designed for cleaning wooden deck and fence with
pressure washer. Avoid harsh chemicals that may harm the environment or your wood.
Scrub Brush: A soft-bristle scrub brush or a dedicated deck-cleaning brush can help tackle stubborn stains. Garden Hose: Have a garden hose with a spray nozzle ready for rinsing.
Tarps or Plastic Sheeting: Protect nearby plants, furniture, and sensitive areas from overspray and detergent runoff by covering them with tarps or plastic sheeting.
Stiff Bristle Brush: Keep a stiff bristle brush on hand for targeted stain removal.

Now, let's proceed with the step-by-step guide for cleaning your wooden deck and fence in Ontario.

Pressure washing step by step

Step 1: Preparation

Clear the Area: Remove furniture, potted plants, or any obstacles from the deck and fence area. Sweep away loose debris like leaves and dirt.
Cover Sensitive Areas: Ontario's diverse plant life deserves protection. Use tarps or plastic sheeting to shield nearby plants, garden beds, and items that can't be moved. This will prevent them from getting damaged or coated with detergent.

Step 2: Apply detergent

Mix the Detergent: Follow the manufacturer's instructions to dilute the wood-friendly detergent. Typically, a 1:1 ratio of detergent to water works well.
Apply the Detergent: Using a low-pressure nozzle or the detergent injector on your pressure washer, evenly apply the detergent to the wooden surface. Begin from the bottom and work your way up to prevent streaking.
Let It Sit: Allow the detergent to sit on the wood for 5-10 minutes. This gives it time to break down dirt, grime, and stains, which is particularly important for Ontario residents dealing with mold and mildew issues.

Step 3: Cleaning with pressure washer

Set the Pressure: Adjust the pressure washer to a low setting, usually around 500-600 PSI. High pressure can gouge or splinter the wood, so you should know the difference between pressure washing and soft washing.
Maintain Distance: Hold the pressure washer nozzle about 12-18 inches away from the wood's surface. Consistently maintain this distance to avoid causing damage.
Work Methodically: Start at one end of the deck or fence and work your way across the surface, following the wood's grain. Overlap each pass by about 50% to ensure even cleaning.
Use a Sweeping Motion: Instead of concentrating the nozzle in one spot, employ a sweeping motion to clean the surface evenly. This minimizes the risk of streaks or gouges.
Be Patient: Take your time, especially when tackling stubborn stains on your deck and fence. Multiple passes may be necessary to achieve the desired results, especially for Ontario residents combating mold and mildew.

Step 4: Rinse thoroughly

Switch to Rinse Mode: Disconnect the detergent supply and switch your pressure washer to rinse mode.
Rinse from Top to Bottom: As with detergent application, rinse from the top down to prevent streaking. Ensure you remove all detergent residue from the wood.

Step 5: Post-washing maintenance

Allow to Dry: Let your deck and fence air dry completely, which may take a day or two, depending on Ontario's weather.
Inspect for Damage: While your wooden surfaces are drying, inspect them for any signs of damage, such as loose boards, splinters, or protruding nails. Make any necessary deck and fence repairs promptly.
Seal or Stain: Consider applying a wood sealer or stain to protect your deck and fence from Ontario's varied weather conditions. This should be done once the wood is completely dry.
Regular Maintenance: To extend the life of your wooden structures and maintain their beauty, perform routine inspections and cleaning as needed, usually once a year.
