Keeping your home clean goes beyond curb appeal. Regular house exterior cleaning protects siding, paint, and other surfaces from dirt, mildew, and algae that can cause damage over time. But how often should you clean your home’s exterior? The answer depends on your environment, siding type, and local conditions.
General Guidelines for House Exterior Cleaning
Most homes benefit from a professional pressure washing or soft washing service on the following schedule:
- Once a year – this keeps dirt, pollen, and pollution from building up
- Every 6–9 months – if you want it looking sharp year-round or live in a messier environment
When You Might Need Cleaning More Often
Certain conditions can increase how quickly your exterior gets dirty:
- You see mildew or algae (common in humid or shady areas)
- Your house is near trees (sap, pollen, birds)
- You’re close to water. (pond, creek, river, or lake}
- You live near busy roads or construction (dust + grime)
When You Can Go Longer Between Cleanings
Some homes can extend the cleaning schedule safely if:
- You live in a dry climate
- Your house gets lots of sun
- The siding stays visibly clean
How Materials Affect House Exterior Cleaning
Different siding materials need different care:
- Vinyl siding: every 12–18 months
- Wood siding: once a year (soft wash only—too much pressure can hurt it)
- Brick / stucco: every 1–2 years unless you see staining
Using the wrong cleaning method can shorten the life of your exterior surfaces.
Cleaning Methods: Soft Washing vs High Pressure
Pro tip: If you’re pressure washing, low pressure + detergent beats high pressure every time. High pressure can force water behind your siding or damage paint.
Soft washing provides a deeper, longer-lasting clean while protecting your home from damage.
Routine house exterior cleaning helps maintain curb appeal, protect your investment, and prevent costly repairs. Choosing the right schedule and method is key to keeping your home in top condition.
