How long before painting should the wash be done?
One to two weeks before the painter starts is the sweet spot. That allows full drying time and room for weather delays on either job.

Pre paint washing: why painters want a clean surface first
Paint sticks to clean, not to grime
Every exterior wall carries a film of chalk, mould, salt and dust, even when it looks clean. Paint applied over that film bonds to the film, not to the house. That is why paint jobs on unwashed surfaces peel and bubble years early.
The wash is the cheapest part of a repaint and the part that decides how long the expensive part lasts.
What a pre paint wash removes
A proper pre paint wash removes chalking from old paint, kills mould and algae at the root, lifts salt deposits and clears the dust and cobwebs from eaves, corners and joinery. What is left is a sound surface the new coating can actually grip.
This is a different job from a standard house wash. It is done to the standard painters ask for, with extra attention to the areas painters complain about most.
When to book it
The sweet spot is one to two weeks before your painter starts. That gives the surface time to dry fully and gives you room in the schedule if weather shifts either job. Your painter can tell you their preferred gap and we will work to it.
If scaffolding is going up, tell us. Washing before the scaffold goes up is faster and cheaper than working around it.
