- Visible Dirt and Grime
- Accumulation of dirt, dust, or stains on surfaces like siding, driveways, patios, or decks.
- Mold, Mildew, or Algae Growth
- Green or black streaks on siding, fences, or outdoor furniture indicate organic growth that can damage surfaces.
- Oil or Grease Stains
- Driveways, garages, or concrete surfaces with noticeable spills or stains.
- Discoloration or Fading
- Surfaces look dull or faded due to sun exposure and dirt build-up.
- Preparation for Painting or Staining
- Cleaning before applying paint, stain, or sealant ensures better adhesion and a longer-lasting finish.
Seasonal Timing
- Spring: After winter, pressure washing removes dirt, salt, and debris that have accumulated.
- Fall: Clear leaves, moss, and debris before colder temperatures set in.
- Summer: Ideal for cleaning decks, patios, and outdoor furniture as they are in heavy use.
- Avoid Winter: Freezing temperatures can cause water to freeze on surfaces, leading to potential damage.
Surface-Specific Considerations
- Siding: Clean annually or as needed, especially if you notice mold or dirt build-up.
- Driveways/Sidewalks: Wash every 1-2 years or more frequently if oil or grime accumulates.
- Decks/Fences: Power wash before staining/sealing or when algae and dirt build up.
- Roofs: Use soft washing techniques to avoid damage and remove moss or algae.
Environmental Triggers
- After a storm or heavy rain that leaves dirt or debris.
- In shaded, damp areas prone to moss or mildew growth.
- Following construction or renovation to remove dust and debris.
Maintenance Schedule
For most surfaces, annual or biannual cleaning is sufficient. However, high-traffic areas like patios or driveways may need more frequent attention. Regular inspections will help identify when power washing is necessary.
