A coating can only bond to what it touches. We strip off the chalking, mould spores, salt and grease first, so the paint your painter applies is stuck to the substrate and not to the dirt.
Exterior paint in Far North Queensland fails for reasons that are almost always present before the first coat goes on. Chalking — the powdery layer an old coating sheds as its binder breaks down — acts as a release agent between the substrate and whatever is painted over it. Mould spores left in the surface do not die under paint; they carry on growing and push through it. Salt haze near the coast, grease around a carport, tannin from overhanging trees: all of it sits between the wall and the new coating.
None of it is visible once the first coat is on, which is exactly the problem. The job looks perfect on the day and then bubbles, flakes or shadows through eighteen months later, at which point the paint gets blamed for something the preparation caused.
A proper pre-paint wash removes the contamination, kills the growth at the root rather than sealing it in, and leaves a surface that is sound, clean and dry. It is the least visible thing anyone does on a repaint and the one that decides how long the whole job lasts.

A pre-paint wash is not just a harder version of a house wash. The goal is different: not "looks clean" but "will hold a coating". That means treating the growth so the spores are dead rather than merely rinsed off the surface, and removing chalking without driving water into joints the painter then has to wait out.
It also means knowing when to stop. Pressure high enough to strip sound, well-adhered paint creates a feathered edge the painter has to sand back anyway, and forces moisture into a substrate that then needs days to dry before it can be coated. Preparation that creates work for the next trade is not preparation.

We prepare. Your painter paints. We are deliberately not in that business.
Surface repair, gap filling and priming are the painter’s trade.
Pre-1970s coatings are a regulated removal job requiring a licensed contractor.
We remove what is failing and contaminating. Taking sound paint back to substrate is a different scope.
Blown render, rot and cracking get photographed and handed on.
We can guarantee the surface we hand over is clean. What happens after that belongs to the coating and whoever applied it.
Most of this work is booked by trades rather than owners, and these are the things they actually care about.
The substrate has to be genuinely dry before coating. Scheduling the wash a sensible number of days ahead is part of the job, not an afterthought.
What is sound, what is chalking and what is already lifting — photographed so the painter knows before quoting.
No feathered edges from over-aggressive stripping, and no water driven into joints that then have to dry out.
Windows, doors, vents and external fittings closed and protected before anything is applied.
Scaffold, drop zones and access left usable rather than covered in runoff residue.
Roof before walls, walls before glass, and all of it before the painter’s first coat.
Built around the painter’s start date, because that is the only date that matters here.
When the painter starts is the first question, because everything else is scheduled backwards from it.
Elevations measured remotely for straightforward properties, in person for commercial or complex sites.
In writing, naming the elevations and surfaces, and confirming the handover date.
Coating condition documented — useful for you, and often useful for the painter’s own quote.
Growth treated at the root, contamination removed, surface rinsed and left to dry.
Photo record supplied, and the surface handed over clean, sound and dry.

Plenty do, and plenty do it well. The difference is the treatment: rinsing a wall removes what is on the surface, while treating it kills the mould at the root so it does not grow back through the new coating. That is the failure mode we are being paid to prevent.
Long enough that the substrate is properly dry, which depends on the material, the weather and the time of year. Tell us the painter’s start date and the wash gets scheduled backwards from it.
It removes what is already failing — chalking, flaking and anything not adhered — but it is not a stripping service. Sound paint stays on, because taking it off creates edges and drying delays the painter then has to deal with.
Regularly, and it is often the easiest way to run it. Painters and builders book this as a scheduled prep step, and the photo record goes to whoever needs it.
Pre-1970s coatings can contain lead, and removing them is a regulated job for a licensed contractor. If we suspect it, we stop and tell you rather than wash it into your garden.
