You've staged the inside, touched up paint, and the listing goes live in two weeks. The single highest-ROI improvement you can still make? A professional exterior wash.
What buyers notice first
Online listings live or die on the first photo. Dingy siding, green algae and a dirty driveway scream "deferred maintenance" — even if everything inside is perfect.
The pre-listing wash checklist
- House siding (especially the photographed front and any algae-streaked walls)
- Driveway, walkways and front porch
- Decks, patios and outdoor living spaces
- Fences visible from the street
- Garage doors and exterior trim
Realtor-friendly turnaround
Most listings need the wash completed before the photographer arrives. A typical home gets cleaned in a single morning — schedule the wash one to two days before photo day for best results.
The numbers
The National Association of Realtors consistently lists exterior cleaning among the highest-ROI pre-sale improvements, with returns often well above 100%.
