Most standard-sized decks (approx. 200–300 sq. ft.) with moderate organic growth typically range from $350 to $500.
Please note: To maintain our professional standard of care, we have a $350 minimum service visit. Because smaller decks may fall below this threshold, many clients maximize their value by bundling a deck wash with a house wash or window cleaning to receive a multi-service discount.
What factors drive the cost of deck cleaning?
Several variables determine the final quote:
- Material: Wood (pressure-treated, cedar) requires different cleaning agents and dwell times than composite materials like Trex.
- Organic Growth: Heavy moss, lichen, or deep-seated black mould requires a more intensive treatment than light surface algae.
- Accessibility: We factor in whether the deck is a simple ground-level platform or a multi-story structure with stairs and railings.
- Surrounding Vegetation: We invest extra time in protecting the landscaping and gardens often found directly adjacent to decks.
