Is it possible to pressure wash a pergola? Pressure washing is an efficient method of cleaning, especially compared to manual scrubbing, which is why it is favored by many property owners. When done incorrectly, though, pressure washing can result in irreversible damage. As such, it is important to know proper pressure washing techniques.
Can You Pressure Wash a Pergola?
Pergolas can elevate the appearance of any outdoor area, making it feel fresh and whimsical. As with most structures, though, pergolas also require their fair share of maintenance. Over time, pergolas can start to look old and worn. This mainly happens due to exposure to natural elements such as sunlight, dirt, and plants. And your once-pristine pergola can turn into a filthy, algae-ridden archway.
One method of cleaning pergolas is to do it the old-fashioned way — with a bucket and a scrub. However, due to their height and composition, pergolas are notoriously difficult to clean. They’re hard to reach, and it’s not always possible to get into the nooks and crannies.
This is where pressure washing comes in.
Pressure washing is an efficient and effective way to clean pergolas. Thanks to the force of high-pressure water, you can simply blast away the contaminants stuck to the structure. When used in tandem with detergents, you can achieve better results and even restore your pergola to its near-original appearance.
Can You Power Wash a Pergola?
In general, you can use a power washer to clean your pergola. Power washing is similar to pressure washing, exception of water temperature. A power washer uses heated water to clean surfaces, whereas pressure washers don’t.
Power washing a pergola is possible and can be very effective against stubborn oil or grease stains. However, it is important to note that power washers are not always compatible with all types of pergolas. If you have a wooden pergola, it is best not to use hot water to clean it. This is because hot water may bend the wood as it can soften its fibers.

Tips on How to Pressure Wash a Pergola
When executed improperly, pressure washing can leave long-lasting damage behind. As such, don’t go in blind, especially if you’re new to pressure washing. Pressure wash a pergola the right way using the following tips.
1. Wear Protective Gear
Before starting any pressure washing job, make sure to wear the proper protective gear. This includes goggles, gloves, and heavy-duty footwear. Believe it or not, pressure washing can lead to serious injuries, so it is best to come prepared.
2. Protect Surrounding Areas
Aside from protecting yourself, you should also protect the surrounding structures and spaces. Move any furniture and potted plants away from the cleaning area. Make sure kids and pets stay indoors, too. If any immovable objects are around, such as plants or a garden, wet them with water and cover them with a tarp to avoid contaminating them with detergent.
3. Inspect for Damage
Don’t just start blasting your pergola with your pressure washer. Make sure to inspect the structure for any signs of damage first. If you find any, it is best to address the damage first. Pressure washing a damaged pergola can worsen its condition.
4. Maintain a Safe Distance
Standing too close to the structure while pressure washing it can lead to injury and irreversible damage. In addition to the PSI level and the nozzle tip, proximity plays a crucial role in determining the force of the water. As such, starting at least 2 feet away is a good idea, moving closer as necessary.
5. Start With a Low-Pressure Setting
Beginning any pressure washing job with a low-pressure setting is always recommended. This way, you can avoid damaging the surface. You can adjust and increase the setting as necessary. The pressure level will depend on the type of material you’re cleaning.
6. Test on a Small Area
You may be eager to clean your pergola, but don’t let that eagerness get the better of you. Test your pressure washer on a small, inconspicuous part of your pergola first. This way, you can make adjustments as you see fit without dealing damage to an obvious area.
7. Use the Right Nozzle
The nozzle tip you use can also influence the force of the water. The narrower the nozzle, the more concentrated the force. When in doubt, starting with a broader nozzle, such as the fan nozzle, and working your way up is a good idea.
8. Work in Sections
For a more efficient job, divide the pergola into sections and work on one section at a time. This way, you can also keep track of the portions you have already cleaned.
9. Use a Consistent Speed
When pressure washing pergolas, it is best to use sweeping motions at a consistent pace. Don’t linger in any portion of the pergola, as this can result in damage.
