Q: I’ve got lots of spider webs and general dirty exterior walls. How often should I have them power-washed?
A: Light power washing should be done every 2-3 years for most homes. The exception is if you have red-clay dirt that the rain splashes up to your home. The iron oxide can permanently stain your home if not taken care of ASAP. You should then install proper landscaping (like rocks) to prevent this in the future.
