Pressure Washing: What Property Owners Should Know
Pressure washing can make a dramatic difference, but good results depend on matching the method to the material and controlling where dirty wash water goes.
Good candidates
- Sound concrete walks and patios
- Many durable exterior surfaces after a small test area
- Some decks and porches at appropriate pressure
- Commercial sidewalks and entry areas
- Selected dumpster and service-area surfaces with runoff controls
Surfaces that need extra caution
- Loose or peeling paint
- Aged wood or soft materials
- Damaged siding
- Historic masonry
- Areas where water can be driven behind finishes
- Surfaces that may contain lead paint or hazardous residues
Runoff matters
- Dry-sweep loose sediment and debris before washing when practical.
- Avoid intentionally directing dirty wash water into storm drains.
- Review nearby drains, slopes and sensitive areas before commercial cleaning.
- Use detergents only when appropriate for the surface and disposal plan.
Before the appointment
- Move vehicles and fragile outdoor items.
- Close windows and identify known leaks.
- Point out outlets, damaged siding and water-sensitive areas.
- Provide access to an approved water source if the service requires it.
Official Minnesota stormwater references
For commercial or runoff-sensitive sites, Minnesota Pollution Control Agency stormwater guidance is a useful starting point for wash-water and pollution-prevention planning.
