Cremyll wall cleaning without high pressure
Foot-ferry to Plymouth beside Mount Edgcumbe.
We work Cremyll as part of the Millbrook round, which keeps travel down. Wall softwash is the service most often asked about here because painted stone and render shows growth earlier than brick does.
Cremyll is identified by its foot-ferry connection to Plymouth beside Mount Edgcumbe, with painted stone and render beneath slate. On a compact estuary-side elevation, containment and material transitions deserve equal attention. The survey marks ferry- or road-facing boundaries, garden edges, openings and every point where paint crosses from masonry onto render. Deposits are checked rather than labelled from location alone. Separate discreet trials help compare coated stone with render, while downpipe tracks and sheltered returns reveal whether moisture follows a fitting or a broader exposure pattern. The final sequence is based on those observations and the available working space.

Shade, damp and run-off
- Where a hose reel or water butt overflows against a wall, the staining follows the overflow path exactly.
- A wall behind a dense fence panel is in still air permanently, and still air never dries anything quickly.
- An untreated wall carries a spore load already, so regrowth after a rinse is faster than first growth ever was.
- Soil banked above the damp course keeps the base of a wall permanently wet.
- A tree removed years ago can leave a wall that greened in its shade and never fully recovered.
- A textured coating applied over an already dirty surface holds that dirt as a feeding layer.
- Rendered plinths take more water than the main face and are usually the first thing to look tired.
- Frost damage opens the surface slightly, which gives the next season's growth somewhere to sit.
- Spores travel on the wind and land everywhere. What decides whether they take hold is whether the surface stays damp.

- Recorded character: estuary hamlet. Foot-ferry to Plymouth beside Mount Edgcumbe.
- Typical roof covering here is slate, which affects what washes down onto the walls.
- Millbrook sits about 1.9 miles from Cremyll on our round, so visits are often shared.
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.
- Bead edges and stop ends on a rendered elevation are the details worth protecting from driven water.
- Cleaning before repainting is not optional, because paint over live growth fails from underneath.
- Where a painted wall has been patch-repainted, the patches clean at a different rate.
- Slate-faced walls shed water quickly but the bedding mortar does not.
- Copings on stone boundary walls take the worst of the weather and the worst of the growth.
Reading the surface
- 01Whether the growth has spread onto glass and frames tells you how long it has been established.
- 02Hollow-sounding render is checked by tapping before any water is put onto it.
- 03Where the pattern is vertical and narrow, plumbing is looked at before chemistry is.
- 04The direction the growth thickens in points at the source of the moisture.
- 05Any staining that continues below ground level is a drainage question, not a cleaning one.
- 06Where paint is peeling in flakes rather than powdering, adhesion has already gone.
- 07The mortar is tested with a key at a discreet point, since soft mortar sets the whole method.
- 08The age of the finish is estimated before a strength of mix is chosen.
Why order matters more than speed
Glass is done last on any multi-service visit, since it picks up whatever the earlier stages put in the air.
Gutters are cleared between the roof and the walls, so the first heavy rain does not restain a finished elevation.
Solar panels are cleaned separately from the roof slope they sit on, and after it.
Driveways come after walls so that run-off from the elevation is rinsed away as part of the drive work.
Before the day in Cremyll
- Let us know if scaffold or a tower is already up for other work.
- Note the position of the stopcock in case the outside tap needs isolating.
- If you have a pond, a water butt or a wildlife area, point it out in advance.
- Point out ground-floor windows that are painted shut, as they need different masking.
- Say where the outside tap is, and whether it runs at any pressure.
- Say if a conservatory or lean-to abuts the elevation, so glazing can be sheeted.
- Flag any recent repair or repaint, because fresh work is treated more gently.
- If there are children's toys or a trampoline against the wall, they need to move.

Before you get in touch
- Is the finish even across the wall?
- That is the main reason we work bottom-up and one elevation at a time.
- Can you quote from photographs?
- For most straightforward jobs, yes. Awkward access is worth a look in person.
- Do I need to move my car?
- It helps. If it cannot be moved we sheet it or work around it.
- Will it strip my paint?
- Sound paint is unaffected. Paint that has already lost adhesion may lift, which is why a test patch goes on first.
- Do you take the waste away?
- There is very little on a wall job. What comes off the surface is rinsed to a drain that can take it.
- Can you clean a wall before painting?
- Yes, and it should be done first. Paint over live growth fails from underneath.
- How long before I can repaint?
- Several dry days after the wall has been treated and rinsed.
- Do you clean boundary walls too?
- If they take the same method as the house, yes, in the same visit.

That is the whole enquiry. We come back with what we would do and what it costs.
The short version
The finish underneath is usually intact. It is the film on top that has aged. One elevation, two elevations or the whole property. The method does not change, only the time it takes. Ask what will be used and how long it will be left on. The answers tell you everything.
