Vinyl wants chemistry. Wood wants restraint.
Vinyl fencing responds beautifully to a soft wash: the algae and mildew that turn white panels green die on contact and rinse away, and the panels come back bright without a single high-pressure pass. Post caps, hinges, and gate hardware get detailed as part of the job.
Wood is the surface I see butchered most. High pressure on wood raises the grain like wet cardboard, especially around fasteners. Wood fences and decks get cleaned at low pressure with a wood-appropriate mix, which lifts the gray weathering and growth without tearing up the surface. If a fence is old and fragile, I will tell you what cleaning can and cannot do for it before we start.
Straight answers
The questions I actually get, answered the way I answer them on the phone.
Can you get my white vinyl fence white again?
Usually yes. Green and black organic staining comes off well with soft washing. Deep scuffs or UV yellowing are a different story, and I will tell you which is which when I see it.
Will you pressure wash my wood fence?
Not at high pressure. Wood gets low pressure and the right cleaner so the grain stays intact. That is the difference between cleaned and chewed up.
