Can a Pressure Washer Damage Your House?

Yes, a pressure washer can potentially harm your house if not used accurately. This effective cleaning tool uses high-pressure water to shoot away dirt and slime, but it can also deprive paint, harm siding, and break windows if you’re not careful. Here are some of the methods a pressure washer could harm your house

Key Takeaways:

• Can strip paint if pressure too high or nozzle too close.
• Can chip siding – use lower pressure and wider spray.
• Can cause water damage and moisture issues.
• Can crack windows and doors. Don’t aim at them.
• Can damage roof shingles and cause leaks. Keep nozzle moving.
• Can cause injury through cuts or bruises. Wear protective gear.
• Dispose of wastewater properly.
• Avoid electrical hazards. Keep water away from outlets.
• Start low, test first, keep distance, avoid fragile areas.
• Follow manufacturer’s instructions.
• Hire a professional if unsure.

Removing Paint and Finish

If the pressure is fixed too high, or the nozzle is kept too near to a painted surface, it can deprive of the paint. This is also true for finishes on terraces and other wood frames.

Damage to Siding

Vinyl and wood siding can be chipped by a pressure washer, specifically if you use a narrow spray design or if the pressure is too elevated. The water can also get underneath the siding, leading to moisture problems down the line.

Water Damage

Pressure washing can lead to water damage if the water is forced into the walls or under the shingles. This can cause mold, rot, and other moisture-related problems down the line.

Window and Door Damage

Windows and glass doors are especially weak to pressure washers. A direct hit can crack the glass and potentially damage window and door seals, leading to leaks.

Roof Damage

Pressure washing a roof can loosen shingles and cause granule loss, especially on asphalt shingles. Water can also be forced under the shingles, inducing leaks and water harm inside your home.

Personal Injury

Pressure washers can be dangerous if not used correctly. The high-pressure water can cause lacerations, bruises, and even broken bones if it comes into contact with your skin. It’s essential to wear protective gear such as gloves, goggles, and boots when using a pressure washer.

Environmental Impact

Pressure washing can have a negative impact on the environment if the wastewater is not disposed of properly. The water can contain chemicals, dirt, and other pollutants that can harm plants and animals. It’s important to follow local regulations when disposing of pressure washing wastewater.

Electrical Risk

Water and electricity are a hazardous mix. If water from a pressure washer fetches into electrical outlets, lights, or other electrical tools, it can generate short circuits and pose a considerable safety risk.

To detour damage, always start with a low-pressure setting and a vast spray pattern, and then slowly increase the pressure as required. Test on an unnoticeable area first, keep a secure distance from your house, and detour from spraying windows or electrical equipment directly.

As with all tools, it’s essential to read and obey the manufacturer’s teachings for your special pressure washer. If you’re not satisfied doing it yourself, consider employing professional pressure washing assistance.
