Wall cleaning for estuary hamlet property in Radford
Radford, Devon - PL9
Most enquiries from Radford start with one elevation that has gone darker than the rest. Nine times out of ten the reason is how long that face stays damp, not how dirty it is.

How the work is actually carried out
- 1.The colour keeps improving for a fortnight after the visit as dead growth loses its grip and weathers away.
- 2.Heavy lichen gets a second lighter application on a later visit instead of an increase in pressure on the first.
- 3.Any surface that will be walked on afterwards is left rinsed rather than left with residue.
- 4.Every hose junction is checked before pressure goes on, because a burst at a coupling floods a border.
- 5.The lower band of an elevation is checked for salt or silt staining, which is rinsed rather than treated.
- 6.Kit is set down on a groundsheet rather than on planting or paving joints.
- 7.Beds and borders at the foot of the wall are soaked with clean water first, so any run-off arrives diluted.
- 8.Fixings for hanging baskets and washing lines are unloaded before the elevation is worked, then put back.
- 9.Gutter faces and fascia boards are wiped as part of the same pass, since they sit in the same spray path.
- 10.External light fittings are switched off at the consumer unit before the elevation around them is treated.
Reading the finish on a Radford elevation
- Modern render, whether sand and cement or a thin-coat system, has a slightly porous face that holds airborne spores.
- Coloured through-render fades gradually, so what looks like dirt on an older wall is sometimes age in the finish.
- That gets pointed out before work starts rather than discovered halfway through.
- A weaker mix and a longer wait suits paint better than anything stronger and faster.
- Limewash over cob is sacrificial and will lift if treated as though it were masonry paint.
- Cracks in a cob wall are structural information, not cosmetic, and are reported rather than cleaned.
The reasons behind the staining
- Painted walls chalk with age, and chalked paint is a rougher surface than new paint.
- Where a wall carries a heavy climbing plant, the fabric behind it is nearly always damper than the rest.
- Where a downpipe discharges into a gully that has silted, the overflow soaks the wall base each winter.
- Once lichen is established it holds water itself, which makes the surface beneath it wetter than it started.
- Cold bridging at a lintel can keep a narrow band of render damper than everything around it.
- Rain shadow works both ways: the sheltered face stays dry of rain but also of the washing that rain provides.
- Sheltered gable ends collect airborne spores because there is no wind to move them along.
- Growth thickest at head height usually means splash from a hard surface rather than run-off from above.
- Growth that appears in a neat rectangle usually marks something that was leaning against the wall.
Practical points to sort first
- If parking needs a permit or a bay suspension, tell us early.
- Say if the elevation is overlooked by a neighbouring window that should stay shut.
- Note any external socket or garden power run near the base of the wall.
- Flag any recent repair or repaint, because fresh work is treated more gently.
- Move cars off a drive that runs tight to the house if you can, and tell us if you cannot.
- Note where hoses can be run without crossing a doorway.
- Tell us if a gutter has been overflowing, because that changes what we look at first.
- Say if any part of the wall has been jet washed before, and roughly when.
How the wall is read first
- 01Where the wall carries a previous coating over render, its edges are inspected for lifting.
- 02The mortar is tested with a key at a discreet point, since soft mortar sets the whole method.
- 03A wall that is warmer than its neighbours on a cold morning is likely holding moisture.
- 04How quickly a splash of water darkens the surface says how porous the finish has become.
- 05A damp meter reading inside a stained corner separates a cleaning job from a building problem.
- 06Whether the render is thin-coat or traditional is checked at a bead or a reveal.
- 07Where the pattern is even across the whole face, exposure and aspect are the cause.
- 08The angle of morning sun on the elevation tells you how long it stays damp.
Before you get in touch
- Can you deal with black spotting on white render?
- That is usually a fungal spot rather than algae. It responds to treatment but often needs a second lighter pass.
- Can you do it while I am at work?
- Yes, as long as gates are unlocked and we can reach the elevations.
- Does softwash actually kill the growth or just wash it off?
- It kills it. The treatment is left on long enough to work, which is why the surface keeps lightening for a week or two after the visit.
- Do you clean under the eaves?
- The soffit line is in the spray path and gets a pass as part of the work.
- Can lichen be removed completely?
- The organism is killed, and what is left weathers off. Deeply rooted lichen on stone can take a season to fade.
- Is there a smell?
- There is a mild one during application that clears within a few hours.
- Do you need a parking space?
- Somewhere within hose reach of the elevation is enough.
- Can you clean a wall before painting?
- Yes, and it should be done first. Paint over live growth fails from underneath.

The short version
Read the staining pattern first and the answer usually names itself. Every coated wall has a maximum pressure it tolerates, and it is much lower than most people assume. The point is not a clean wall for a fortnight. It is a wall that stays clean because the roots went with the surface growth. Monday to Saturday, 8am to 7pm.
