Rilla Mill walls: method before pressure
We work Rilla Mill as part of the Callington round, which keeps travel down. Wall softwash is the service most often asked about here because granite and painted render shows growth earlier than brick does.

What helps before we arrive
- Note any external socket or garden power run near the base of the wall.
- If parking needs a permit or a bay suspension, tell us early.
- Note where hoses can be run without crossing a doorway.
- Mention shared access or a right of way that we will be crossing.
- Point out any alarm sensor mounted externally on the elevation.
- Note where the electricity meter and consumer unit sit relative to the wall.
- Mention any planned decorating so the drying window can be built into the date.
- Trim back anything that has grown tight against the wall, or ask us to work around it.
Wall build-ups common in PL17
- A rendered plinth takes more water than the face above it and is usually the first band to look tired.
- A rendered wall under a failed drip detail restains within a season however well it was cleaned.
- A test patch low down and out of sight is how failing paint is found deliberately.
- Colour on a painted wall usually returns once the film on top is removed.
- Granite cills and thresholds collect the heaviest lichen because they stay wet longest.
- Second lighter applications suit granite better than one strong pass.
Diagnosis before treatment
- 01The state of the pointing is judged at the most exposed corner, not the most convenient one.
- 02A wall that feels chalky under the hand is telling you the coating has aged, not that it is dirty.
- 03Where the pattern is even across the whole face, exposure and aspect are the cause.
- 04Old repair patches are identified early, because they take treatment differently from the surrounding finish.
- 05Weep holes are counted and checked for blockage while the wall is being read.
- 06How quickly a splash of water darkens the surface says how porous the finish has become.
- 07Where the pattern is a band at the bottom, splash from the ground is doing it.
- 08Where the wall carries a previous coating over render, its edges are inspected for lifting.
Damp, airflow and what feeds growth
- Where a hose reel or water butt overflows against a wall, the staining follows the overflow path exactly.
- Concrete render plinths wick moisture upward from the ground more readily than the face above them.
- A wall shielded by a car port dries slowly because it never sees direct sun or driven rain.
- Where two elevations meet in a tight internal corner, neither one dries properly.
- An untreated wall carries a spore load already, so regrowth after a rinse is faster than first growth ever was.
- North-east corners hold frost longest and thaw slowest, which extends the damp window every morning.
- Sheltered gable ends collect airborne spores because there is no wind to move them along.
- 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.
What to book before and after the walls
Small repairs to pointing are best done after cleaning, when what needs doing is visible.
Anything that involves opening a gutter is done before the ground beneath it is cleaned.
Booking services out of order is the commonest reason a clean seems not to have lasted.
If windows were cleaned recently, tell us, and they get sheeted rather than redone.
How a softwash visit runs
- 1.Weep holes above openings are left clear so the wall can drain the way it was designed to.
- 2.Rainwater goods are checked while the elevation is being worked, since a blocked hopper explains most single-strip staining.
- 3.A wall backing onto a public pavement is worked at times that keep the spray arc away from passers-by.
- 4.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.
- 5.Treatment goes on from the bottom of the elevation upwards, which stops clean streaks forming where liquid runs onto dry surface.
- 6.Downpipe backs and the strip of wall behind them are done by hand, because a sprayed pattern always misses them.
- 7.Treatments are kept away from vegetable beds entirely, with those sections sheeted rather than diluted.
- 8.Mortar joints that have already lost material are pointed out and left alone rather than washed further open.
- 9.Between elevations the kit is rinsed so nothing dries in the line and blocks the fan pattern.
- 10.Corners are worked from both directions so the overlap sits in the angle and not on the open face.
Questions Rilla Mill owners ask
- Can the whole outside be planned in one go?
- Yes, and getting the order right matters more than doing it all at once.
- 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.
- How long before I can repaint?
- Several dry days after the wall has been treated and rinsed.
- Do you clean soffits and fascias?
- They are in the same spray path, so they are done as part of the wall visit.
- Will my drive be slippery afterwards?
- Anything walked on is rinsed clear before we leave.
- Do you cover air bricks the whole time?
- Covered while the wall around them is worked and uncovered before we go.
- Do you treat garden and boundary walls on their own?
- Yes, where the method matches and access allows.
- 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.
Where Rilla Mill sits on our round
- Callington sits about 2.7 miles from Rilla Mill on our round, so visits are often shared.
- Recorded character: village. Lynher-valley village east of the Cheesewring.
- PL17 covers 2 town hubs and 7 villages or districts in our radius.
- Typical roof covering here is slate, which affects what washes down onto the walls.
- Postcode district: PL17. County: Cornwall. Approx 15.7 miles from the PL3 base.

Small job, same care
A porch, a plinth or a single gable is still worth doing properly.
To sum up for PL17
Water in the wrong place explains most tired elevations, and it is cheaper to fix than to keep cleaning. The quiet visit is the good one. Noise usually means pressure. If the staining sits in the substrate rather than on it, we will say so before taking the work on. Monday to Saturday, 8am to 7pm.
