A pressure washer in the wrong hands can cause expensive water damage. The goal is to clean your house, not to flood your attic or ruin your siding. So, how do you prevent water damage while pressure washing? The key is to understand that it’s not just about pointing or shooting. It’s a process that requires the right technique and extreme caution. Most homeowners try to do it themselves because they think professional services can cost too much. Well, those services are certainly cheaper than the replacement. Still, even if you want to hire a professional, you should know how they get the job done. Read on!
How Pressure Washing Causes Water Damage?
Before you can prevent water damage, you need to know how it happens. The most common cause of water damage is forcing water into places it shouldn’t go. This can happen in several ways:
If you aim the pressure washer directly at the seams or from an upward angle, you can easily drive water behind your wood or stucco. Hence, it causes moisture, which leads to rot, mold, and eventually structural damage.
- The high water pressure can break or degrade the caulking and seals around windows and doors. So, water can sweep in through the gaps.
- Spraying water directly into attic vents, soffits, or exhaust vents is a direct route for water to enter your walls and attic.
- Using too much pressure can strip paint, which makes it vulnerable to water absorption.
Understanding these risks is the first step in a safe and effective cleaning process.
What to Do Before You Begin Pressure Washing?
This step can make or break the whole result. A successful pressure washing job starts long before you pull the trigger on the power washer. First, do a thorough inspection of the entire surface you plan to wash. These are weak spots that are especially vulnerable to a high-pressure stream of water.
Cover electrical outlets, light fixtures, and vents with plastic sheeting and painter’s tape. Make sure the seals around your windows and doors are intact. If you see any cracked or missing caulk, now is the time to re-seal it.
Choosing the Right Pressure Washer & Nozzle
Pressure washers come in different sizes and levels of power, measured in PSI (pounds per square inch) and GPM (gallons per minute). For most residential cleaning tasks, an electric pressure washer with a PSI between 1300 and 1900 is sufficient.
The nozzle you choose is just as important as the pressure washer itself. Nozzles are color-coded to indicate the angle of the spray.
- Red (0 degrees): This is a pinpoint jet stream. It is extremely powerful and should almost never be used for washing your house. It can easily gouge wood, crack vinyl siding, and damage concrete surfaces.
- Yellow (15 degrees): This nozzle provides a narrow, powerful spray for tough oil stains on hard surfaces, but it’s often too much pressure for siding.
- Green (25 degrees): This is a great all-purpose nozzle. It provides a good balance of cleaning power and coverage.
- White (40 degrees): This nozzle has a wide spray pattern and is ideal for more delicate surfaces and for rinsing.
- Black (Soap nozzle): This nozzle has a low-pressure setting and is used to apply a cleaning solution.
For washing your house, the green or white nozzle is almost always the best choice.
What to Do If Water Damage Occurs?
First, stop pressure washing immediately. Assess the area to see where the water went. If you’ve forced water behind siding, you need to let it dry out. This can take time. If you notice water spots on interior walls or ceilings, the problem is more serious.
In this case, it’s best to call a professional. They can use moisture meters to determine the extent of the water intrusion and recommend the best course of action. Trying to fix significant water damage yourself can often make the problem worse.
When to Call for a Professional Service?
If you’re not comfortable using a power washer, if your home is more than one story tall, or if you’re dealing with delicate or damaged surfaces, hiring a professional service is the safest bet.
Professionals have commercial-grade equipment and, more importantly, the experience to know exactly what water pressure and cleaning solution to use for each surface. They are trained to work efficiently and safely, minimizing the risk of water damage and ensuring a perfect finish.
A professional power washing service might seem like an extra cost, but it can save you thousands in costly repairs if something goes wrong with a DIY job. Understand how to clean the composite decking with pressure washing.
