Sherford (South Hams) wall cleaning without high pressure
Parish south of Kingsbridge (not the Sherford new town).
If the walls on your Sherford (South Hams) property have gone patchy or green, the finish itself is usually sound. Parish south of Kingsbridge (not the Sherford new town), and growth on cob and painted render sits on the surface rather than in the structure.

Shade, damp and run-off
- Wall growth often maps exactly to where a previous extension roof used to sit.
- Once lichen is established it holds water itself, which makes the surface beneath it wetter than it started.
- A wall behind a dense fence panel is in still air permanently, and still air never dries anything quickly.
- Shading from a neighbouring building can matter more than the aspect of the wall itself.
- Roof valleys concentrate run-off, so the wall under a valley outlet is loaded more heavily than anywhere else.
- A patio laid up against a wall reflects splash onto it every time it rains hard.
- Nutrients from a nearby feeding lawn or planting drift onto a wall and give growth something to work with.
- Concrete render plinths wick moisture upward from the ground more readily than the face above them.
- Driven rain sticks to a wall face rather than running off it, which keeps the surface wet long enough for spores to settle.

Surfaces this page is written for
- Render that has lost its water repellency absorbs surface water instead of shedding it, which extends every damp spell.
- Render responds to dwell time better than almost any other finish, which is what makes softwash suit it.
- That gets pointed out before work starts rather than discovered halfway through.
- Where a painted wall has been patch-repainted, the patches clean at a different rate.
- Cob and lime-finished walls are moisture-sensitive by design.
- Cob walls dry slowly, so work is planned for a dry settled stretch.
Reading the surface
- 01The age of the finish is estimated before a strength of mix is chosen.
- 02Where paint is peeling in flakes rather than powdering, adhesion has already gone.
- 03Old repair patches are identified early, because they take treatment differently from the surrounding finish.
- 04A test patch at low strength shows what the surface will do before the full elevation commits to it.
- 05A fingernail drawn across the growth says more in a second than a photograph does.
- 06Cracks are traced to their ends, because a crack that runs to an opening behaves differently from one that stops.
- 07The elevation is read from the pavement first and from a metre away second.
- 08Anything that cannot be explained by water is treated with more caution, not less.
Why order matters more than speed
Roof work always precedes wall work, because everything released from the slope lands on the elevation below it.
Where a roof clean is planned for later in the year, walls are worth leaving until after it.
A wall treated in autumn goes into winter clean, which is when it matters most.
Where only walls are being done, the gutter line is still checked, because it is the usual culprit behind the worst staining.
Before the day in Sherford (South Hams)
- Tell us about any planting you particularly care about at the base of the wall.
- Tell us if a fence panel is loose, because sheeting gets pegged to something solid.
- Let us know if scaffold or a tower is already up for other work.
- Point out any window that does not seal properly, so it gets sheeted rather than sprayed near.
- Tell us if a gutter has been overflowing, because that changes what we look at first.
- Note the position of the stopcock in case the outside tap needs isolating.
- Point out any alarm sensor mounted externally on the elevation.
- Mention any planned decorating so the drying window can be built into the date.

Questions Sherford (South Hams) owners ask
- Should the gutters be done at the same time?
- Usually. Overflow is behind a large share of wall staining, so clearing it protects the work.
- Is a second visit ever needed?
- For heavy lichen, a lighter second application later beats increasing pressure on the first.
- Can you work around a conservatory?
- The glazing is sheeted first and given a rinse at the end.
- Can you work while builders are on site?
- Better after they finish, so their dust and debris does not land on clean work.
- Can you clean render on an insulated system?
- Yes, with extra care around bead edges where water should not be driven in.
- 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.
- What about the neighbour's side?
- We only work surfaces you own or have permission for, and we check before spraying near a boundary.
- Will treatment damage a wildlife pond?
- Ponds are sheeted and run-off is diverted well away from them.

Guides worth a look first
To sum up for TQ7
Low pressure, biocidal treatment, dwell time, controlled rinse. That is the whole method and it is chosen because the finish survives it. The wall is nearly always sound. What has changed is what is living on it. Where the cause is plumbing, cleaning is a cosmetic answer to a practical problem.
