by | Jan 3, 2022 | Blog | 0 comments

There are several benefits to using a pressure washer to clean your wood siding. First, it’ll get rid of all the dirt, grime, and mildew that have accumulated over time. Second, this method will leave behind an even, streak-free finish that won’t require any additional cleaning or prep work before staining or painting. Before we get started, let’s make sure you have everything you’ll need:

Things Needed To Pressure Wash Wood Siding

  • Pressure washer (preferably at least 2200 psi)
  • Clean clothes and towels to wipe away any water drops
  • Garden hose and nozzle (to remove the power cord from the equation—plus, it makes life easier. You’ll only be using one hand.)
  • Pressure washer-safe detergent (if needed)
  • Protective eyewear and rubber gloves (wear long sleeves and pants, too—the high-pressure water can really sting!)
  • Garden hose screen or mesh to keep small objects from being blasted into your yard

How to Pressure Wash Wood Siding

Now let’s discuss in detail that how you can pressure wash your wood siding.

Step 1: Pick your ideal pressure-washer setting

On a cold winter day, it might be tempting to crank the heat up and pick a high-pressure setting to get started. But when cleaning wood siding during any other time of year, you’ll want to start on a middle setting—somewhere between the 2200-PSI wash and an angled setting. This will allow us to knock off the larger dirt particles without removing all the wood’s natural oils.

Step 2: Clean your first section

For a pressure washer to work properly, you’ll need to hold it at a 45-degree angle to the siding and sweep from left to right or vice versa. Just be sure that you’re overlapping each pass by a few inches to avoid any unsightly streaks. Stop the machine every 20 seconds or so to check your progress and immediately wipe up any drips that have been collected on the section you’re working on. If those drops aren’t wiped up quickly, they’ll leave unattractive trails as they roll down the side of your house!

Step 3: Rinse your entire wall

Once you’ve finished the first section, move to the next one and start over. Continue this process until you’ve reached your final section.

Step 4: Relax (and maybe even enjoy yourself)

Now comes the good part—you get to relax as the pressure washer rinses away all of that hard work for you! Just make sure to keep the nozzle trained at the ground so that any leftover dirt is carried away with the water. As always, be careful not to point it in your eyes or anyone else’s.

Pressure Washing Wood Siding is Easier than You Might Think

If you’re intimidated by power tools or just never got around to buying one, don’t worry—pressure washing wood siding isn’t brain surgery. And while you might not want to tackle this project on your own just yet, there’s no shame in asking your friends or family members for help if needed.

Benefits of Pressure Washing

Pressure washing is the best way to clean your wood siding, but it also has some other advantages:

  • Time savings: You won’t be scrubbing and rinsing by hand. (How many of us dread coming up with chores to do during our weekends?)
  • Money savings: As we mentioned, you should never need to replace your siding because of mildew or mold—just pressure wash it and be on your way!
  • Safety: You won’t need to haul ladders around your yard, and you’ll never come close to any electrical sockets (which can be a shock hazard).
  • Wood Siding Maintenance: Consider the Extra Touch of Sealing

Once your wood siding has been pressure washed, you can rest easy, knowing that it’s as clean as possible. But just as a car needs regular oil changes to run smoothly, your house needs periodic maintenance to keep those exterior surfaces in great shape.

In addition to cleaning and sealing your wood siding every few years, consider using an annual power-wash and seal as a means of preventing thatch build-up and restricting mildew and mold growth (especially on the South and West sides of your home, where they’re most likely to grow).

Precautions While Pressure Washing

While pressure washing can do a lot of good for your home, it does have its limitations. Some surfaces might not be able to handle the jet of water, so always read the label on your cleaning solution carefully before beginning. Never use cleaners that are designed for one type of material on another—doing so could damage both surfaces!

When you do begin cleaning your wood siding with a pressure washer, be sure to proceed slowly and gently. Remember: these machines pack a punch (just like your muscles), and you never want to lean into them so much that you lose control of the machine or put too much stress on your own body.

Oh, and one final thing: if you’re going to be using a gas-powered pressure washer, always make sure that it is started upon a level surface. Doing so would prevent injury from accidental tipping and could even save your house from damage due to an unexpected explosion!

How Often Should You Pressure Wash Your Wood Siding?

The frequency with which you pressure wash your wood siding depends on a number of factors, most notably where you live and how close you live to the nearest body of water.

If you live in an area that tends to be humid or generally wet, then it’s especially important to clean and reseal your siding at least once every two years. If you live in a drier area that doesn’t experience a lot of rain, then once every three years should do the trick.

The Bottom Line

So there you have it! Now you’ve got all of the information you need to begin pressure washing your wood siding with confidence and ease. And if you’re still feeling a little unsure about the whole thing, just remember that you always have the option of picking up the phone and calling in an expert. Be sure to keep your safety and the safety of your house and the wood siding so that you may not have to face a big loss.
