What % of your work is pressure washing?
Hard to say
Traditionally "deck recovery" has been a large part of my seasonal work
This includes PWing....but see the answer below
Would you rather just stain a deck or do you not mind power washing it.
I don't mind at all
If I had my druthers, I'd just as soon follow a properly cleaned and prepped deck
I have done so working for other companies
In my case often the PWing is not sold as an add-on or stand alone
It's simply a prep tool
In the case of decks, it's often part of a "apply mildecide, pw it off, apply deckcleaner pw it off, apply wood brightener, pw it off" process
Doing it with a hose would take way to long
Same with exterior prep
It's expedient and efficient
However, I would not mind simply following after a properly cleaned exterior, as I have done when working for others
