Step by step
Cover nearby plants and close windows/vents.
Use a wide-fan nozzle (25-40 degrees) to avoid gouging siding or wood.
Work top to bottom on siding, in overlapping passes.
Keep the nozzle 12+ inches from the surface and test on a hidden spot first.
For concrete driveways, a narrower nozzle and closer distance is fine for stains.
Questions to ask your pro
- What PSI do you use on my siding material, and how do you adjust for vinyl versus wood versus stucco?
- Do you offer soft washing as an alternative for delicate surfaces like painted wood or stucco?
- What cleaning chemicals or detergents, if any, will you apply?
- How will you protect windows, plants, outdoor electrical outlets, and light fixtures?
- Can high-pressure water be driven behind my siding, and how do you prevent that?
- Are you insured for any accidental property damage during the job?
