Wall softwash for Portwrinkle homes
Portwrinkle, Cornwall - PL11
Everything below applies to painted stone and render elevations in Portwrinkle, inside the PL11 area we cover in full. The method is set by the surface and the exposure, and nothing else changes it.
What Portwrinkle walls are usually finished in
- A rendered plinth takes more water than the face above it and is usually the first band to look tired.
- Coloured through-render fades gradually, so what looks like dirt on an older wall is sometimes age in the finish.
- Painted masonry can be cleaned, though a paint film that has already lost adhesion will lift where it was going to fail anyway.
- Cleaning before repainting is not optional, because paint over live growth fails from underneath.
- Slate-faced walls shed water quickly but the bedding mortar does not.
- The rinse on stone is gentle enough that nothing is driven into an open joint.
Low pressure, longer dwell
- 1.Treatment goes on from the bottom of the elevation upwards, which stops clean streaks forming where liquid runs onto dry surface.
- 2.A hose test on the nearest outside tap happens before anything is mixed, because flow rate changes how the day is planned.
- 3.Vents, extractor terminals and trickle vents get taped, because water pushed into them is the one thing that turns an exterior job into an interior one.
- 4.Rainwater goods are checked while the elevation is being worked, since a blocked hopper explains most single-strip staining.
- 5.Expected rain is considered before application because the treatment needs suitable dwell time on the wall.
- 6.On render below a flat roof edge, the drip detail is checked, because a failed one puts the stain straight back.
- 7.Photographs are taken of anything found in poor condition, so it can be shown rather than described.
- 8.Airbricks are covered for the duration and uncovered before we leave, without exception.
- 9.Kit is set down on a groundsheet rather than on planting or paving joints.
- 10.Where a lean-to gutter runs at wall height, it is cleared first so it does not overflow mid-visit.
Small things that make the visit smoother
- Say if there is a wasp or bird nest under the eaves, and we will plan around it.
- Tell us about any previous treatment that came back quickly, and how quickly.
- If parking needs a permit or a bay suspension, tell us early.
- Say if you would prefer the front done on a different day from the back.
- If a security light or camera covers the elevation, tell us so it can be isolated.
- Flag any recent repair or repaint, because fresh work is treated more gently.
- Move cars off a drive that runs tight to the house if you can, and tell us if you cannot.
- Point out any window that does not seal properly, so it gets sheeted rather than sprayed near.
Facts on record for Portwrinkle
- Typical wall finish here is painted stone and render, which sets the cleaning method.
- Access is usually via A374 and Torpoint Ferry.
- Postcode district: PL11. County: Cornwall. Approx 8.9 miles from the PL3 base.
- Recorded character: harbour hamlet. Tiny fishing harbour on the west end of Whitsand.
- PL11 covers 4 town hubs and 12 villages or districts in our radius.
What is actually growing on the wall
- Concrete render plinths wick moisture upward from the ground more readily than the face above them.
- A wall behind a dense fence panel is in still air permanently, and still air never dries anything quickly.
- A leaking outside tap or an unlagged pipe can be the entire reason one corner of a house looks different from the rest.
- Growth returns fastest where the underlying cause was never dealt with, which is usually water going somewhere it should not.
- Growth on a painted wall often sits on top of a paint film that has already begun to chalk.
- Washing without a biocide simply resets the clock and leaves the roots in place.
- Wall growth often maps exactly to where a previous extension roof used to sit.
- Lichen anchors into the surface rather than resting on it, which is why brushing achieves nothing and pressure achieves damage.
- Lichen prefers hard, alkaline surfaces, which is why it shows on mortar and cills before it shows on render.
Assessing a PL11 elevation
- 01Where the wall carries a previous coating over render, its edges are inspected for lifting.
- 02The presence of moss rather than algae suggests standing water rather than damp air.
- 03A short section of hose test shows whether run-off drains away or ponds at the base.
- 04Where paint is peeling in flakes rather than powdering, adhesion has already gone.
- 05Where the pattern is vertical and narrow, plumbing is looked at before chemistry is.
- 06Whether the property is exposed or sheltered is judged on the day, not from a map.
- 07Photographs taken before work provide the reference for judging the result later.
- 08Whether the render is thin-coat or traditional is checked at a bead or a reveal.

Questions Portwrinkle owners ask
- What happens to the growth after it dies?
- It loses its grip and weathers off over the following weeks, which is why the wall keeps improving.
- Can you work while builders are on site?
- Better after they finish, so their dust and debris does not land on clean work.
- Do you leave a written record of what was done?
- Photographs of before and after the visit, plus anything found in poor condition.
- Can you tell from a photo whether it will clean up?
- Usually yes for surface growth. Staining that is in the material is harder to judge without seeing it.
- What if part of the wall does not come up?
- It is left to weather rather than pushed harder, and we will say what we think is happening.
- Will the treatment harm my planting?
- Beds are wetted down first so run-off arrives diluted, and rinsing is directed away from anything growing.
- Is thin-coat render different from sand and cement?
- Yes, and it is more sensitive. Thin-coat systems get a weaker mix and a longer dwell rather than more pressure.
- Can you treat one elevation only?
- Yes, and it is common. Often only the shaded side has a problem and the rest of the house needs nothing.
A single gable counts
Small jobs get the same preparation and the same method as large ones.
To sum up for PL11
Photographs and a postcode are enough to start a conversation about the work. The point is not a clean wall for a fortnight. It is a wall that stays clean because the roots went with the surface growth. Written scope first means nothing is discovered late. Monday to Saturday, 8am to 7pm.
