Can you treat one elevation only?

Yes, and it is common. Often only the shaded side has a problem and the rest of the house needs nothing.

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.

Do you offer a maintenance visit?

A lighter top-up treatment every couple of years is much less work than leaving it until it is heavy again.

Can I get the roof done at the same time?

Yes, and the roof goes first so what comes off it does not land on clean walls.

Can you clean a wall covered in ivy?

The ivy needs removing first. Once it is off, the shaded face behind it is treated as normal.

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.

Do you clean soffits and fascias?

They are in the same spray path, so they are done as part of the wall visit.

Do you treat garden and boundary walls on their own?

Yes, where the method matches and access allows.

Treating growth on painted render and stone in West Looe

West Looe, Cornwall - PL13

West Looe is a harbour hamlet within the PL13 area, roughly 15.6 miles out from PL3 and one of 17 places we cover in that district. Its painted render and stone walls behave in a predictable way once you know the exposure.

West Looe occupies the west bank of the Looe estuary and is recorded with painted render and stone beneath slate. A useful survey divides the façade into estuary-facing, street-facing and recessed zones, then records coating edges and masonry joints within each. Access, neighbouring boundaries and drainage routes can influence how an application is contained. Surface deposits are identified rather than presumed to be one coastal contaminant, and stone receives its own test away from painted margins. This creates a measured plan for dwell and collection while recognising that the condition of an individual West Looe wall is more important than its postcode.

How the work is actually carried out

1.The van is parked so hoses do not cross a footpath, and matting goes down where they have to.
2.External drains below the work are covered with a grate mat and cleared before we leave.
3.Fence panels tight against a wall are wetted first so run-off does not sit on dry timber.
4.The strength of mix is stepped up only after a weaker one has been given its full dwell and judged.
5.Paving, steps and paths below the elevation are rinsed clear at the end of the visit.
6.Every hose junction is checked before pressure goes on, because a burst at a coupling floods a border.
7.Ridge and verge debris that has landed on the wall head is brushed off dry before anything wet goes on.
8.Treatments are kept away from vegetable beds entirely, with those sections sheeted rather than diluted.
9.External light fittings are switched off at the consumer unit before the elevation around them is treated.
10.Dwell time is the active ingredient. The treatment is left on the growth long enough to kill it rather than being chased off with water.

Reading the finish on a West Looe elevation

Bead edges and stop ends on a rendered elevation are the details worth protecting from driven water.
Where render sits over insulation, the wall is more sensitive still and the mix is weakened accordingly.
Masonry paint over render adds a film that traps moisture if the substrate was damp when it was applied.
Peeling in flakes means adhesion has gone; powdering under the hand means the surface has simply aged.
Loose stones and open joints are recorded and left alone rather than washed.
Treatment on stone is applied in stages so it soaks into the joints rather than running off the faces.

The reasons behind the staining

Roof debris shed from a mossy slope lands on the same band of wall year after year.
Roof valleys concentrate run-off, so the wall under a valley outlet is loaded more heavily than anywhere else.
Silt washed down from the roof leaves a thin feeding layer on the render below.
Cracked render lets water sit behind the face as well as on it, so the staining pattern follows the crack.
An untreated wall carries a spore load already, so regrowth after a rinse is faster than first growth ever was.
Black spotting on white render is a different organism from the green film beside it, and it clears at a different rate.
Concrete render plinths wick moisture upward from the ground more readily than the face above them.
Growth thickest at head height usually means splash from a hard surface rather than run-off from above.
A blocked hopper head can soak the same square metre of wall for an entire winter without anyone noticing.

Practical points to sort first

Mention shared access or a right of way that we will be crossing.
Note where the electricity meter and consumer unit sit relative to the wall.
Say if any part of the wall has been jet washed before, and roughly when.
If parking needs a permit or a bay suspension, tell us early.
Trim back anything that has grown tight against the wall, or ask us to work around it.
Close and latch every window on the elevations being worked, including any small top lights.
Warn us about a soft lawn or an unmade drive so boards come on the van.
Mention any cladding or timber detail that you would rather was left alone.

How the wall is read first

01The direction the growth thickens in points at the source of the moisture.
02Efflorescence is distinguished from lichen before anything is applied, since one is salt and one is alive.
03Cracks are traced to their ends, because a crack that runs to an opening behaves differently from one that stops.
04The ground level relative to the damp course is checked before the base of a wall is treated.
05Where a wall meets a roof abutment, the flashing is looked at first.
06Photographs taken before work provide the reference for judging the result later.
07Hollow-sounding render is checked by tapping before any water is put onto it.
08A slow walk of the gutter line from the ground finds most of the causes worth fixing.

To sum up for PL13

Nothing on this page needs a site visit to price if you can send a couple of clear photographs. The difference between rinsing and treating is invisible on the day and obvious six months later. Doing the roof, gutters and walls in the right order is most of the value. Monday to Saturday, 8am to 7pm.
