Treating growth on painted render and stone in Pillaton Village
Pillaton Village, Cornwall - PL12
Where a Pillaton Village wall has gone patchy rather than evenly dirty, the cause is nearly always local: a downpipe, a hedge, a shaded corner. That is where we look first.

How the work is actually carried out
- 1.Between elevations the kit is rinsed so nothing dries in the line and blocks the fan pattern.
- 2.Windows are checked from inside where access allows, because a closed window with a broken seal still lets water past.
- 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.Paving, steps and paths below the elevation are rinsed clear at the end of the visit.
- 5.A wall in deep shade is worked earlier in the day, when there is most light on it to judge coverage.
- 6.The finished wall is photographed in the same light as the start photograph, so the comparison is honest.
- 7.Where a bay window projects, its cheeks are treated separately from the main face to avoid a shadow line.
- 8.The lance tip is changed rather than the pressure raised whenever coverage is not even enough.
- 9.The mix is made up in small batches as the work moves, rather than one large batch that stands and weakens.
- 10.The colour keeps improving for a fortnight after the visit as dead growth loses its grip and weathers away.
Reading the finish on a Pillaton Village elevation
- Modern render, whether sand and cement or a thin-coat system, has a slightly porous face that holds airborne spores.
- A rendered wall under a failed drip detail restains within a season however well it was cleaned.
- Painted masonry can be cleaned, though a paint film that has already lost adhesion will lift where it was going to fail anyway.
- Colour on a painted wall usually returns once the film on top is removed.
- A stone wall in deep shade holds moss in the joints long after the faces have dried.
- Loose stones and open joints are recorded and left alone rather than washed.
The reasons behind the staining
- A tree removed years ago can leave a wall that greened in its shade and never fully recovered.
- Where two elevations meet in a tight internal corner, neither one dries properly.
- Roof valleys concentrate run-off, so the wall under a valley outlet is loaded more heavily than anywhere else.
- Airflow through a passage between two houses is fast but the passage itself is in permanent shade.
- Salt spray does not itself grow, but it roughens and holds damp, which is the same outcome.
- Wall growth often maps exactly to where a previous extension roof used to sit.
- Roof debris shed from a mossy slope lands on the same band of wall year after year.
- Rain shadow works both ways: the sheltered face stays dry of rain but also of the washing that rain provides.
- Rain running off an unsealed timber fascia carries tannin down the wall as a brown stripe, not growth at all.
Practical points to sort first
- If there are children's toys or a trampoline against the wall, they need to move.
- Say if the elevation is overlooked by a neighbouring window that should stay shut.
- Say if there is a wasp or bird nest under the eaves, and we will plan around it.
- Bring in washing, cushions and anything fabric that lives against the wall.
- Say whether the property is occupied during the day, since that changes nothing technically but helps the plan.
- Tell us if a fence panel is loose, because sheeting gets pegged to something solid.
- Mention whether the drive drains to a soakaway that already struggles in heavy rain.
- Point out where the render was patched, since patches clean differently from the original.
How the wall is read first
- 01The angle of morning sun on the elevation tells you how long it stays damp.
- 02Any staining that continues below ground level is a drainage question, not a cleaning one.
- 03Where the pattern is a band at the bottom, splash from the ground is doing it.
- 04Nearby properties with the same finish are a useful reference for what is normal on that street.
- 05Efflorescence is distinguished from lichen before anything is applied, since one is salt and one is alive.
- 06Where the pattern is a band at the top, the gutter line is doing it.
- 07A short section of hose test shows whether run-off drains away or ponds at the base.
- 08Cracks are traced to their ends, because a crack that runs to an opening behaves differently from one that stops.
Questions Pillaton Village owners ask
- Do I need to move my car?
- It helps. If it cannot be moved we sheet it or work around it.
- What about air bricks and vents?
- Covered for the duration, uncovered before we leave.
- Can you get behind downpipes?
- Yes, by hand. It is the part a sprayed pattern always misses.
- Can you do it while I am at work?
- Yes, as long as gates are unlocked and we can reach the elevations.
- Do you clean soffits and fascias?
- They are in the same spray path, so they are done as part of the wall visit.
- What if I only want the front done?
- That is the most common request on this kind of job.
- Is there a smell?
- There is a mild one during application that clears within a few hours.
- Will you tell me if the gutters are the real problem?
- Yes, and it is common enough that the gutter line is checked on every wall visit.

Plan the whole outside once
Roof, gutters, walls and hard surfaces in the right order costs less trouble than doing them piecemeal.
To sum up for PL12
The visit is quiet, low pressure and unremarkable to watch. The result is the interesting part. One elevation done properly is better than four done quickly. A first clean is the heavy one. What follows is maintenance, and maintenance is quicker every time. Monday to Saturday, 8am to 7pm.
