Your home takes a beating from the elements—rain, sun, mold growth, mildew buildup, dirt and algae over time can make your house look less than perfect. Pressure washers are a powerful tool for keeping your home clean outside, but how often should you use a power washer on your house? The answer depends on several factors—climate, location, type of siding and your personal preference.
What is Pressure Washing, and Why Is It Important?
Pressure washing uses high pressure water streams to clean exterior surfaces like siding, driveways and decks. Power washers can be adjusted to different pressure settings depending on the surface being cleaned—from soft surfaces like wood siding to hard surfaces like brick. Power washing removes dirt, grime, mold growth and mildew buildup that can accumulate over time especially on homes near dirt roads or high humidity.
It not only improves curb appeal but also prevents long term damage from contaminants like mold growth, mildew growth and organic material buildup. When done right a power washing service can even extend the life of your exterior paint and other building materials.
How Often to Power Wash
- Climate and Weather Conditions
If you live in an area where it rains and is humid, mould and mildew growth are common. Homes in those areas may need to be power washed more often, about twice a year, to prevent dirt and algae from building up on exterior surfaces. In dry areas, once a year is enough.
Tip: Check for mold growth after the cooler months and fall months, especially if your home is in the shade or damp area. The rule of thumb is to wash as soon as you see visible signs. - Location of Your Home
Homes near dirt roads or areas with lots of foliage tend to collect dirt and debris from trees, especially during windy seasons. These homes need more frequent power washing. Power water from professional pressure washers will blast away built up dirt and organic matter that may not be visible but can cause mold growth or damage over time. - Type of Siding and Exterior Material
Different types of siding react differently to pressure washers. Wood siding is more delicate and may need lower pressure to avoid damage. Vinyl siding and aluminium siding can handle more pressure but still need to be treated with care. Using too much pressure can remove loose paint or damage softer surfaces.
Pro Tip: For homes with vinyl siding, aluminium siding or delicate materials, always hire a professional pressure washing service that knows how to adjust the stream of water for optimal distance and pressure setting. - Personal Preference and Aesthetic Goals
Some homeowners are more particular with the look of their home and want it to look spotless all year round. If that’s you, you may want to power wash every 6 months to maintain a fresh look. Whether it’s getting ready for a new paint job or just to maintain a clean exterior, regular power washing keeps your home looking its best.
Pro Tip: Perfect time to power wash is right before painting or after any harsh weather events that leaves debris on your home’s exterior. - Preventive Maintenance and Damage Control
Regular power washing is key to preventing damage caused by mold growth, mildew growth and built-up dirt over time. When mold or mildew growth takes hold of your home’s exterior, it can eat away the material, causing long term damage. Power washers remove these harmful substances before they can cause more serious problems.
Preventive Care: Power washing services can also help you avoid costly repairs down the line by removing contaminants from surfaces that may otherwise cause damage to exterior paint or other building materials.
How to Pressure Wash Safely
If you’re going to DIY pressure wash, you need to use the right equipment and follow the right safety protocols. Here’s how:
- Choose the Right Power Washer: Electric power washers are best for residential use as they have enough pressure to clean without damaging window screens or soft washing for wood siding. Commercial-grade power washers and diesel power washers have more power but are best left to pros for big jobs like concrete driveways or brick driveways.
- Wear Protective Gear: Safety goggles, gloves and protective clothing are a must to protect yourself from the high pressure water stream. Always keep a safe distance from the surface you’re cleaning to avoid injury or damage.
- Watch Out for Electrical Outlets: Be careful of electrical outlets or cords when using hot water or soapy water to clean as these can be a hazard if not properly protected.
- Use the Right Nozzles: Different degree nozzles are available for power washers. The fan nozzle for example is great for covering a large surface area without applying too much pressure, perfect for delicate surfaces like wood siding or exterior house wash.
- Keep the Right Distance: Keeping the right distance from the surface you’re cleaning ensures you’re using the right amount of pressure without damaging exterior materials or stripping paint.
Why Regular Pressure Washing
Regular pressure washing your home has many benefits:
- Curb Appeal: A clean exterior can transform your home’s look, make it more attractive to potential buyers, or make it more enjoyable for you.
- Prevents Mold and Mildew Growth: Mold growth and mildew buildup are not only ugly but can also damage your home. Regular pressure washing prevents these contaminants from spreading and causing costly repairs.
- Protects Exterior Paint: Built up dirt, mold and mildew can erode exterior paint over time. By removing these contaminants regularly you extend the life of your paint job.
- Increases Property Value: A well-maintained home is a valuable asset. Whether you’re selling or want to take pride in your property, regular pressure washing increases its value and longevity.
- Safe and Healthy Environment: Contaminants from mould, dirt, and organic matter can harm your health. Regular pressure washing removes these hazards and creates a healthier living environment for you and your family.
