Low-pressure wall treatment across Notter
Bridge crossing on the Lynher between Saltash and Landrake.
Notter is a estuary hamlet within the PL12 area, roughly 6.8 miles out from PL3 and one of 21 places we cover in that district. Its painted stone and render walls behave in a predictable way once you know the exposure.
Notter's record places it at the Lynher bridge crossing between Saltash and Landrake. Painted stone and render are listed together, so the inspection needs a clear boundary map before treatment begins. Stone texture, pointing, painted margins and rendered repairs can each absorb and release moisture differently. Particular attention goes to bridge-side exposure, low wall sections and any channels made by roof water, but the actual staining pattern remains the evidence used on site. A small test area should sit on the least conspicuous representative finish, not across a junction where two materials could give a misleading result.

Monday to Saturday, 8am – 7pm
Shade, damp and run-off
- Growth thickest at head height usually means splash from a hard surface rather than run-off from above.
- A wall that never takes direct sun stays damp for hours after everything else has dried, and that extra time is the whole story.
- Rain running off an unsealed timber fascia carries tannin down the wall as a brown stripe, not growth at all.
- A tree removed years ago can leave a wall that greened in its shade and never fully recovered.
- Low winter sun never reaches the bottom third of a wall behind a fence, and it shows.
- A cracked cill throws water back at the wall instead of clear of it.
- North and east elevations dry last and green first, in that order, on nearly every property.
- Painted walls chalk with age, and chalked paint is a rougher surface than new paint.
- Frost damage opens the surface slightly, which gives the next season's growth somewhere to sit.

Surfaces this page is written for
- Thin-coat systems are thinner than people assume, and a jet held still in one place leaves a permanent shadow.
- Patched render takes treatment differently from the original, which is why patches are identified before work starts.
- That gets pointed out before work starts rather than discovered halfway through.
- Masonry paint over render adds a film that traps moisture if the substrate was damp when it was applied.
- Slate-faced walls shed water quickly but the bedding mortar does not.
- Cleaning stone reveals natural colour variation, which some owners expect to be uniform and it never is.
Reading the surface
- 01Colour matters: green suggests algae, black suggests fungal spotting, grey-white crust suggests lichen.
- 02The condition of the cills tells you how much water has been running down the face.
- 03Any staining that continues below ground level is a drainage question, not a cleaning one.
- 04A damp meter reading inside a stained corner separates a cleaning job from a building problem.
- 05Where the wall carries a previous coating over render, its edges are inspected for lifting.
- 06The angle of morning sun on the elevation tells you how long it stays damp.
- 07Whether the property is exposed or sheltered is judged on the day, not from a map.
- 08Cracks are traced to their ends, because a crack that runs to an opening behaves differently from one that stops.
First, next, last
Gutters are cleared between the roof and the walls, so the first heavy rain does not restain a finished elevation.
Where scaffolding is going up for other work, the wall clean is easier and safer while it is standing.
If a decorator is due, the wall clean goes in first and is given time to dry fully.
A first clean is heavier work than the ones that follow, so the interval afterwards can be longer than people expect.
Before the day in Notter
- Say if a conservatory or lean-to abuts the elevation, so glazing can be sheeted.
- Unlock side gates the night before if you are not going to be in, because a locked passage stops a whole elevation.
- If you have a pond, a water butt or a wildlife area, point it out in advance.
- If there are children's toys or a trampoline against the wall, they need to move.
- Mention shared access or a right of way that we will be crossing.
- Say where the outside tap is, and whether it runs at any pressure.
- Mention any cladding or timber detail that you would rather was left alone.
- Note where hoses can be run without crossing a doorway.

Common questions about wall softwash
- What about the smell for neighbours?
- Mild and short-lived, and we avoid boundary elevations when someone next door has washing out.
- What happens if it rains on the day?
- Light rain is workable. Persistent rain moves the visit rather than compromising the treatment.
- Can you remove ivy marks?
- Suckers can be treated and weathered off, though the shadow of an old ivy run can take a season to fade fully.
- Do you offer a maintenance visit?
- A lighter top-up treatment every couple of years is much less work than leaving it until it is heavy again.
- What about the windows afterwards?
- Frames and glass in the spray path are wiped as the masking comes off.
- How long does a visit take?
- A typical two-elevation job is a few hours. A full wrap-around on a larger property is a day.
- Is a lower price ever a bad sign?
- Not automatically, but ask what method is being used. Speed on a delicate finish usually means pressure.
- Will it damage the pointing?
- No. That is exactly what pressure does and softwash avoids.
Book the quiet method
Low pressure means a quiet visit and a finish that survives it.
In a sentence or two
Cleaning reveals condition. Sometimes that means finding a repair, and it is better found than hidden under moss. The wall is nearly always sound. What has changed is what is living on it. If a previous clean did not last, the cause was probably never dealt with.
