Exterior Cleaning in Wimborne Minster
Wimborne is brick and flint country, and flint is the material that catches people out. The stone itself is close to indestructible — it is the mortar holding it in place that gives way, and pressure finds that out very quickly.
The flint stays. The mortar goes.
Banded brick-and-flint walls are all over Wimborne and the villages around it, and they look tough enough to take anything. Flint is glass-hard and will not weather in any human timescale. The problem is that every flint in that wall is held by a comparatively thin bed of lime mortar, and lime mortar is soft by design.
Put a lance on a flint elevation and you will not mark the flint at all — you will wash the mortar out from between the stones. In a bad case flints start coming loose, and re-bedding them is skilled work at a price that dwarfs whatever the clean cost.
The same caution applies to the older soft brickwork through the town centre. Everything here gets low pressure and a treatment that does the work chemically rather than mechanically.
What we clean in Wimborne.
Ask what pressure they plan to use.
If you are getting quotes on an older Wimborne property, that one question tells you most of what you need to know. Anyone who answers with how powerful their machine is has told you they intend to clean your wall mechanically. On flint, lime mortar and soft brick, the right answer is about treatment and dwell time, not pressure — and the job takes longer because of it.
Questions from Wimborne.
Can you clean brick and flint safely?
Yes, and it is worth understanding why care matters. Flint will not weather in any human timescale, but every flint in the wall sits in a thin bed of lime mortar. Pressure does not mark the flint — it washes the mortar out from between them, and re-bedding loose flints is skilled, expensive work.
How often should render be cleaned?
Most properties are on a three to five year cycle. North-facing walls, anything under trees and anything close to the river will green up faster. If you can see growth from the road, it is ready.
Do you cover the areas around Wimborne?
Yes — Colehill, Corfe Mullen, Sturminster Marshall and the surrounding villages are all within our normal area.
Wimborne is around twenty miles south east of our base near Sturminster Newton.
