Does anyone need to be home?

No. It is outside work. Access to the elevations, ideally an outside tap, and windows shut for the visit.

Is a lower price ever a bad sign?

Not automatically, but ask what method is being used. Speed on a delicate finish usually means pressure.

Is the finish even across the wall?

That is the main reason we work bottom-up and one elevation at a time.

What if the render is hollow in places?

It is tapped and mapped first, and hollow sections are treated dry-side only rather than soaked.

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.

What happens if it rains on the day?

Light rain is workable. Persistent rain moves the visit rather than compromising the treatment.

Can you do it while I am at work?

Yes, as long as gates are unlocked and we can reach the elevations.

Do you clean render above a flat roof?

Yes, with the roof covering sheeted and the drip detail checked.

Wall cleaning for estuary hamlet property in Insworke

Insworke, Cornwall - PL10

A wall in Insworke that has greened over is telling you where water sits. Head-of-lake hamlet at Millbrook, so the pattern of staining tends to repeat from one property to the next.

What Insworke walls are usually finished in

Thin-coat systems are thinner than people assume, and a jet held still in one place leaves a permanent shadow.
Where render sits over insulation, the wall is more sensitive still and the mix is weakened accordingly.
A test patch low down and out of sight is how failing paint is found deliberately.
Gloss-painted details like cills are wiped rather than sprayed.
Stone elevations vary enormously in hardness, and the pointing is usually the weakest part.
Slate-faced walls shed water quickly but the bedding mortar does not.

Low pressure, longer dwell

1.The job is worked one elevation at a time from end to end so that nothing dries out mid-wall.
2.External light fittings are switched off at the consumer unit before the elevation around them is treated.
3.On render below a flat roof edge, the drip detail is checked, because a failed one puts the stain straight back.
4.Ridge and verge debris that has landed on the wall head is brushed off dry before anything wet goes on.
5.Cills, frames and glass are wiped down as the masking comes off, so nothing dries as a film on the joinery.
6.A short rinse of the whole face at the end removes residue rather than removing growth, which is a different job done at a different pressure.
7.Hoses run outside gates where children or dogs are about, and gates are closed behind us each time.
8.Between elevations the kit is rinsed so nothing dries in the line and blocks the fan pattern.
9.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.
10.The same operator works a whole elevation so the application rate stays consistent across it.

Small things that make the visit smoother

Say if there is a wasp or bird nest under the eaves, and we will plan around it.
Mention whether the drive drains to a soakaway that already struggles in heavy rain.
Close and latch every window on the elevations being worked, including any small top lights.
Let us know if scaffold or a tower is already up for other work.
Say if the property has a flat roof section that we would be working above.
Point out any window that does not seal properly, so it gets sheeted rather than sprayed near.
Clear the base of the elevation of pots, ornaments and loose paving where you can.
Bring in washing, cushions and anything fabric that lives against the wall.

What is actually growing on the wall

Prevailing wind decides which elevation takes driven rain, and that elevation is nearly always the tired-looking one.
A wall shaded by its own porch roof for half the day dries at half the rate of the face beside it.
Shading from a neighbouring building can matter more than the aspect of the wall itself.
A drying rack or store built against a wall keeps that panel of it permanently shaded.
Pebbledash holds water in the shadow of every stone, so it stays damp long after a flat render has dried.
A single missing tile above an elevation can put water onto the same square metre for years.
Where a downpipe discharges into a gully that has silted, the overflow soaks the wall base each winter.
A wall behind a dense fence panel is in still air permanently, and still air never dries anything quickly.
Lichen prefers hard, alkaline surfaces, which is why it shows on mortar and cills before it shows on render.

Assessing a PL10 elevation

01The underside of the soffit is checked, because staining there rarely stays there.
02The age of the finish is estimated before a strength of mix is chosen.
03The elevation is read from the pavement first and from a metre away second.
04The condition of the cills tells you how much water has been running down the face.
05Anything that cannot be explained by water is treated with more caution, not less.
06Nearby properties with the same finish are a useful reference for what is normal on that street.
07Any staining that continues below ground level is a drainage question, not a cleaning one.
08Cracks are traced to their ends, because a crack that runs to an opening behaves differently from one that stops.
