Beeson exterior wall softwash, Devon
cob and painted render walls, slate roofs, 18.9 miles from the yard.

A wall in Beeson that has greened over is telling you where water sits. Small settlement above Beesands, so the pattern of staining tends to repeat from one property to the next.

Why walls green up in Beeson
- Where a wall sits below a bank or a raised garden, water arrives at it sideways rather than from above.
- Shading from a neighbouring building can matter more than the aspect of the wall itself.
- Where a wall carries a heavy climbing plant, the fabric behind it is nearly always damper than the rest.
- A conservatory or extension roof abutting a wall throws water back at it every time it rains.
- Where two properties share a wall of different finishes, the finishes weather at different speeds and look mismatched.
- Lichen anchors into the surface rather than resting on it, which is why brushing achieves nothing and pressure achieves damage.
- A tree removed years ago can leave a wall that greened in its shade and never fully recovered.
- Concrete render plinths wick moisture upward from the ground more readily than the face above them.
- A path that slopes towards a house rather than away from it keeps the base of the wall wet after every shower.
What the staining pattern tells us
- 01A short section of hose test shows whether run-off drains away or ponds at the base.
- 02A slow walk of the gutter line from the ground finds most of the causes worth fixing.
- 03Hollow-sounding render is checked by tapping before any water is put onto it.
- 04Whether the property is exposed or sheltered is judged on the day, not from a map.
- 05Cracks are traced to their ends, because a crack that runs to an opening behaves differently from one that stops.
- 06Where the pattern is a band at the top, the gutter line is doing it.
- 07Anything that cannot be explained by water is treated with more caution, not less.
- 08A damp meter reading inside a stained corner separates a cleaning job from a building problem.
Getting a Beeson property ready
- Let us know if scaffold or a tower is already up for other work.
- Say where the outside tap is, and whether it runs at any pressure.
- Note the position of the stopcock in case the outside tap needs isolating.
- 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.
- If a security light or camera covers the elevation, tell us so it can be isolated.
- Mention any glazing you already know is cracked before work starts.
- Point out ground-floor windows that are painted shut, as they need different masking.
What the surface will and will not take
- Coloured through-render fades gradually, so what looks like dirt on an older wall is sometimes age in the finish.
- Patched render takes treatment differently from the original, which is why patches are identified before work starts.
- Painted masonry can be cleaned, though a paint film that has already lost adhesion will lift where it was going to fail anyway.
- Painted plinths take splash and are worked as a separate band from the main face.
- Cob walls dry slowly, so work is planned for a dry settled stretch.
- The safest outcome on cob is a lighter, slower improvement rather than an immediate transformation.
The method we would use in Beeson
- 1.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.
- 2.Neighbouring cars and windows are checked before spraying starts on a boundary elevation.
- 3.The lance tip is changed rather than the pressure raised whenever coverage is not even enough.
- 4.Expected rain is considered before application because the treatment needs suitable dwell time on the wall.
- 5.Where a lean-to gutter runs at wall height, it is cleared first so it does not overflow mid-visit.
- 6.Where the growth sits mostly in the lower metre, that band is treated twice and the rest once.
- 7.Areas that stay stubborn after full dwell are left to weather rather than pushed harder on the day.
- 8.Downpipe backs and the strip of wall behind them are done by hand, because a sprayed pattern always misses them.
- 9.The colour keeps improving for a fortnight after the visit as dead growth loses its grip and weathers away.
- 10.Hoses run outside gates where children or dogs are about, and gates are closed behind us each time.
Asked most often in TQ7
- What about the neighbour's side?
- We only work surfaces you own or have permission for, and we check before spraying near a boundary.
- Is timber cladding treated the same way?
- No. Cladding takes a weaker mix, and pressure is avoided entirely because it raises the grain.
- Do you cover air bricks the whole time?
- Covered while the wall around them is worked and uncovered before we go.
- What about air bricks and vents?
- Covered for the duration, uncovered before we leave.
- Do you use a pressure washer at all on a wall visit?
- Only on hard surfaces below it, like paving, and never on the wall finish itself.
- Do you work on flats and shared buildings?
- Yes, with permission from whoever is responsible for the elevation.
- Is there a smell?
- There is a mild one during application that clears within a few hours.
- Can the whole outside be planned in one go?
- Yes, and getting the order right matters more than doing it all at once.
Why order matters more than speed
Where only walls are being done, the gutter line is still checked, because it is the usual culprit behind the worst staining.
A first clean is heavier work than the ones that follow, so the interval afterwards can be longer than people expect.
Where a roof clean is planned for later in the year, walls are worth leaving until after it.
Where gutters need repair rather than clearing, that goes ahead of any cleaning at all.

Beeson wall softwash, in short
Every coated wall has a maximum pressure it tolerates, and it is much lower than most people assume. The finish keeps improving after we leave, which is how you know the treatment did the work rather than the water. Prep takes longer than application, and that is the right way round.

If a previous clean did not last, that tells us something useful before we quote.
