Soft Wash Treatmentacross Buckinghamshire
Buckinghamshire's walls are shaped by chalk hills, narrow river valleys and woodland. We clear algae, lichen and streaking from render, brick, flint, cladding and rooflines at low pressure, with the method set by each surface.

Across the county
Chalk underfoot, woodland overhead and walls that stay damp
Most of southern Buckinghamshire sits on the Chiltern chalk, cut into steep valleys and crowned with beech woods. Those two features decide how quickly a wall dries after rain, and the wall that stays wet is the one that turns green. Soft washing removes that growth with a solution rather than force, which matters on old flint, soft brick and painted render.
Local materials
Flint, brick and clay: what the hills were built from
The chalk beneath the Chilterns gave up flint, and the clay capping the hilltops was dug for brick and tile. So cottages, farm buildings and garden walls across the south of the county are flint bedded in lime mortar, with brick dressings at corners and openings. Lime mortar is soft by design: it lets a wall breathe, and a pressure lance can wash it out of a joint in moments.
Soft Wash Treatment suits these walls because the solution, not the water, does the cleaning. It goes on at low pressure, is left to work on the algae and lichen, and is rinsed off gently, so the flints stay bedded and the pointing stays put. Earlier repairs in hard cement are pointed out before anything is applied.
Valleys and woodland
Why the valley floor greens before the hilltop
The Chilterns are a landscape of dry valleys and chalk streams. The Misbourne, the Chess and the Wye all run through towns on this page, and the Thames marks the county's southern edge. Cool, damp air settles along those valley floors on still nights, and beech woods on the slopes cut off the low winter sun from the houses below them. The walls that suffer most are usually:
- North-facing elevations and gable ends
- Walls within a few metres of a hedge or tree line
- Garden and retaining walls on sloping plots
- Rooflines sitting beneath overhanging branches
Building eras
From railway suburbs to new homes in the vale
The twentieth century added a second layer. The railways brought commuter roads to the south of the county, with houses in render, pebbledash and brick, and the open vale around Aylesbury has seen large new developments in recent decades.
Each era brings its own surfaces. Inter-war render may carry many coats of paint, so the coating is checked before cleaning. Newer homes use through-coloured render, fibre-cement or composite boards and white uPVC fascias and soffits: finished surfaces that a jet can scuff or strip, and that respond well to a measured soft wash.

Soft Wash Treatment in Marlow
Our home town, where river mist and wooded slopes turn eaves, soffits and north gables green first, and painted render gets a gentler hand than bare brick.

Soft Wash Treatment in Amersham
Brick and flint on the Misbourne valley floor and twentieth-century render on the hill above need different handling, and so do the terraced garden walls between them.

Soft Wash Treatment in Aylesbury
Out in the open vale, newer cladding, render panels and white uPVC rooflines mark first on the weather side, and each is cleaned without force.

Soft Wash Treatment in Penn
Flint panels, handmade brick and lime pointing along a wooded ridge, cleaned with a solution and patience so the joints that hold them together survive.

Soft Wash Treatment in Gerrards Cross
Render, brick plinths, stone sills and painted timber often share one elevation beneath tall roadside trees, so each material is soft washed on its own terms.

Soft Wash Treatment in High Wycombe
Across the steep Wye valley, aspect changes street by street, and a wall may carry traffic film near a busy road or living growth on a shaded slope.

Soft Wash Treatment in Princes Risborough
Walls tucked under the escarpment dry slowly while those facing the vale take the weather, and painted coatings are checked before any solution goes on.

Soft Wash Treatment in Chesham
Damp gathers on the Chess valley floor, so we map exactly where growth sits on terraces, cottages and later additions before treating any of it.

Soft Wash Treatment in Great Missenden
A single property may add a timber garage, a composite garden room and a uPVC roofline to its brick and render, each wetted in its own measured way.

Soft Wash Treatment in Bourne End
Where the Wye joins the Thames, the river-facing wall is usually the one that needs the work, with render, clad gables and brick all cleaned at low pressure.

Soft Wash Treatment in Little Marlow
Brick runs through the village, from house walls to steps and retaining walls, and soft washing lifts the growth while leaving weathered pointing in place.

Soft Wash Treatment in Marlow Bottom
Hedges, climbers and branches keep walls and rooflines in this wooded valley damp, so protecting the garden matters as much as treating the wall itself.

Flint and brick cottages and long garden walls under stained copings, cleaned at low pressure with every route for the rinse water planned near the river.

How a soft wash runs
From first look to final rinse
The order is the same anywhere in the county. What changes is the detail at each stage, set by the wall in front of us.
- 01
Free site visit
We walk each elevation, identify the material, the coating and the growth, and note what is planted against the wall, then set out the recommended method in a clear quotation.
- 02
Garden and fabric protected
Borders, lawns, climbers, glazing and painted joinery are covered or wetted down before any solution is mixed, so nothing beside the wall takes up the treatment.
- 03
Low-pressure application
The solution goes on evenly at low pressure across the whole affected area, returns and gables included, rather than only the darkest patches.
- 04
Time, then a gentle rinse
The treatment is left to act on the algae, lichen and mould. Once it has done its work, the wall and the planting beside it are rinsed down with care.
- 05
Chiltern EverGuard™ Treatment
Chiltern EverGuard™ is applied to the clean surface to help reduce regrowth. Protection typically lasts between 12 and 24 months, depending on location, surroundings, surface and maintenance.
Why Chiltern Surface Co
Local to the hills we work in
Based in Marlow
We work from Marlow, at the southern edge of the county, so these valleys, woods and old building materials are ones we deal with routinely.
Method set by the wall
Flint, lime-pointed brick, painted render and modern cladding each get their own approach, decided at the site visit rather than assumed in advance.
Fully insured
Our work is fully insured, and the care taken around your planting, paintwork and neighbours is built into the time we allow.
Honest about limits
If a stain turns out to be salts, a leak or failing paint rather than growth, we tell you, because no amount of cleaning will put that right.

Questions
Soft Wash Treatment in Buckinghamshire: your questions
Is soft washing safe on flint walls with lime mortar?
Yes. It is the approach we prefer on them. The solution does the cleaning and the rinse is gentle, so the joints are not washed out. We still inspect the pointing first and tell you if any of it is already loose, since cleaning cannot hold failing mortar in place.
Why has only one side of my house gone green?
Because that side stays wet for longer. An elevation facing north, into trees or towards a hedge may hardly see the winter sun, while the front dries within hours. Algae needs moisture first, so it follows the shade.
Can you soft wash a house in a conservation area?
Yes. Cleaning is not normally restricted, and our low-pressure method already suits historic fabric. If we find something that would need more than cleaning, such as repointing or re-rendering, that is a matter for you and the local authority, and we will say so plainly.
How long before the green comes back?
That depends on where the house sits. After cleaning, Chiltern EverGuard™ helps reduce regrowth, and protection typically lasts between 12 and 24 months. A wall under beech trees on a valley floor tends towards the shorter end; an open, sunny elevation usually stays clear for longer.
Can you clean timber-clad garages and outbuildings in the same visit?
Yes. Timber, composite and fibre-cement boards on garages, garden rooms and car ports can be soft washed alongside the house, each with a suitable wetting. Timber that is already soft or split is pointed out rather than cleaned hard.
