Quick questions before starting
Preparation is critical; more is needed than having your machine ready. You need to know if you can do the task, what supplies you’ll need for the job, and understand how your pressure washer works.
How difficult is this to do?
In terms of difficulty, pressure washing your fence falls into the medium category.
To carry out this task correctly, you must understand four things: the amount of pressure to apply, the nozzle to use, the spray pattern, and the cleaning product.
How long does it take?
Cleaning a 500-square-foot fence will take around 2 hours (more if it’s larger or dirtier).
How much do materials cost?
- Pressure washer – $160 to $380, or $40 to $100 per day if renting
- Cleaner or detergent – $20 to $29
- Wire brush – $5 to $7
- Rotating scrub brush – $20 to $26
As we quickly touched on, you’ll need four essential items to pressure wash your fence, whatever the material may be.
The machine of your choice is first on the list. The price ranges from $160 to $380, depending on the PSI and GPM, and whether you want to use a gas or electric pressure washer.
Light-duty pressure washers with 1500 to 1900 PSI can work on soft and hardwood, but if you’re also washing other exterior surfaces of your home or your driveway, choose a medium or heavy-duty pressure washer.
The cost of renting a pressure washer can range from $40 to $100 per day, plus any additional fees for picking up and returning the unit.
Cleaner or detergent
Choose an effective and safe detergent for your fence material because some wooden fences are delicate. A good cleaning solution can cost between $20 and $29.
A must-have tool for applying the solution to your fence’s tight corners, these can range from $5 to $7.
Rotating scrub brush
This brush attachment can help break down dirt on more deep stains and costs between $20 and $26.
The average total cost is around $263, but this can vary depending on whether you buy a machine or rent one and the tools you’ll choose to use.
How to pressure wash a fence
Your fence protects your property and deserves that extra care to boost your home’s curb appeal.
Regular washing prevents harmful growths and protects your family, neighbors, and pets.
1. Understand your machine
Before starting any action, we suggest familiarizing yourself with the pressure washer. If this isn’t your first rodeo, skip this step and start prepping the area.
2. Prepare and secure your work area
While moving plants away from the area is better, if it’s not feasible, you can place a drop cloth to cover any parts or plants that need protection from chemicals or intense pressure. Other items to keep in mind are (moveable) structures or assets.
3. Apply the cleaning solution to your fence
Apply the solution to your fence, utilizing the bottom-up method to avoid streaking. We also advise working in sections because you don’t want the solution drying before it’s rinsed.
You will only need to let the solution sit for 5-10 minutes.
If you are faced with tough stains, attach a rotating scrub brush to your wand to help loosen it up.
4. Spray off the solution
After 5-10 minutes, use a 25-degree nozzle to rinse off the solution using the top-bottom method. Remember that for softwood, use 500 – 800 PSI; for hardwood, you can go up to 1,300 PSI.
5. Allow time to dry
Wait for 24 to 48 hours for the fence to dry completely- this is ideal if you plan to put stain, sealer, or paint after cleaning.
Tips and safety considerations
Below are some tips and safety considerations we highly suggest you consider.
Always point your wand in a safe direction
Point your wand away from people, animals, and electrical outlets. High-pressure water can cause severe injuries and property damage.
Test the pressure before starting
Before cleaning, test the pressure on a small or hidden area to ensure it’s at the right PSI setting and will not damage anything.
Use the correct nozzle
Our recommended nozzle tip is the 25-degree, or green nozzle tip.
A lower-degree nozzle may cause damage to your fence, while a higher-degree nozzle might need more pressure to remove dirt and debris from your wall.
Choose the correct type of detergent
The type of soap you use is critical. Choose one that is safe for your fence material and your machine. Different surfaces require different types of soap.

Wear protective equipment
Dirt, debris, and cleaning solutions can easily backsplash on your eyes and body while pressure washing. Wear safety goggles and appropriate protective equipment.
