Rendering in Tolpuddle, lime and limewash
On the older cottages the render is not a covering over the wall, it is part of how the wall stays dry, and that changes what can go back on it.

Rendering in Tolpuddle is often lime work on solid walled cottages, where the render is both the wall's raincoat and its way of drying out. Cracked or hollow cement comes off and is replaced in lime and limewash; sound lime is patched in lime so it knits. A modern silicone or monocouche belongs on newer cavity houses only. The village is a conservation area. Damp inside is a plastering repair, in lime too.
In Tolpuddle the work divides neatly. Either a soft old render is crumbling, spalling at the base or losing its limewash, or somebody has put cement over it and that cement is now hollow, cracked and pulling the face of the wall off with it.
The first is maintenance and often a day or two of patching. The second is a strip and a rebuild. The free site visit in Tolpuddle is a survey with a hammer: we tap the elevation, tell you honestly which one you have, and put the hack off, the beads, each coat, the scaffold and the waste on separate lines in writing.
The work
Patching a lime render, and undoing a cement one
Repairing what is there. A lime render that has lost patches is usually repairable. We cut back to a firm edge, clean down, dampen the background and work a haired lime basecoat in, then a soft topcoat brought flush with the old surface. Patched lime knits into what it meets rather than sitting on it, which is why the repair disappears in a way a cement patch never does.
Limewash and breathable paint. On a Tolpuddle cottage, limewash is a sacrificial coat: it wears, it is renewed, and it keeps the render underneath sound. Several thin coats beat one thick one. Where a house carries modern masonry paint the face has been sealed and the render under it is damp, so the paint comes off before anything else is worth doing.
When cement has to come off. Sand and cement on a pre-1919 solid wall in Tolpuddle keeps water in rather than out. It sounds hollow, the cracking spreads, and moisture trapped behind it comes through inside as a damp patch that no amount of decorating fixes. Hacking it off is dirty work and it is the right work. the published guidance on lime and cement renders sets out why a soft breathable coat outlives a hard one on old fabric.
Thin coat and monocouche where they fit. Not every house in Tolpuddle is a period one. On a post-war cavity wall a silicone thin coat is the sensible system: prepare and stabilise the background, primer, a mesh and scrim reinforced basecoat, then a through-coloured topcoat scraped or floated to a texture off a sample board. Monocouche suits a large plain elevation, and a key is cut where the background is too smooth. Tyrolean and pebbledash can be thrown back over a fresh backing where that is what the house had. Acrylic and polymer rich finishes craze, and none of them go on an old wall.
The base of the wall, and the beads. Render that runs into the ground wicks water up behind itself. It should stop clear on a bellcast bead that throws the drip off the plinth, with stop beads at reveals and verges, stainless rather than galvanised where the wall gets wet. On a lime job the edges are often formed by hand, which takes longer and looks right.
Cracks, hollows and green faces. A hairline crack in lime closes itself over time; a crack that takes a coin in cement will delaminate the coat around it in a winter. Green algae and staining on a shaded gable is a cleaning job unless the wall behind is wet. Thermal comfort comes up too: EWI, external wall insulation board with a render carrier, is an option on a cavity wall, and Part L is the standard, but it is not something to bolt onto a cottage.
How it runs
Rendering and limewashing an older house, in order
Before pricing, Thomas taps every part of the elevation to map the hollow render, checks whether the wall behind is brick, stone or flint, and looks at the sills, the plinth and where the rainwater goes. The written quote itemises access and scaffold, protection, preparation of the wall, the render system and number of coats, beads and stop ends, limewash if wanted, and making good. Thomas is your one contact for the whole job.
On a Tolpuddle job, glass, doors and the garden are sheeted, the scaffold boards are cleared at the end of each day, and hacked off render leaves in our skip. Lime needs time between coats and cover from frost and hot sun, so the programme allows for it. Should the hacking off expose a rotten lintel or a crumbling brick, work stops while you see a photograph and a price.
On a listed building the render is protected fabric, and listed building consent from Dorset Council comes before anything is taken off. The parish carries a long list of listed entries, the Martyrs' Cottages among them. The village also lies inside the Tolpuddle Conservation Area, so a change of finish, texture or colour is a planning matter rather than a repair; ask the council first. Like for like repair in lime is the route that is almost never contentious, which is why it is where we start.
Cost
What decides the price of rendering an old wall
What is already on the wall, and what the wall is made of, decide a rendering price far more than its area.
Hacking off. If old render on a Tolpuddle house sounds hollow over large areas, it all has to come off back to the brick or stone before anything new goes on. That is dusty, slow work, and tapping the elevation before quoting is the only way to know how much.
Lime or modern. On an old solid wall a lime render lets moisture out. Sand and cement, monocouche or a silicone thin coat seal the face, and on the wrong wall they push the damp inside. Lime goes on in more coats, with curing time between, so it takes longer, and it is usually the right answer on walls of this age.
Scaffold around a thatch or a road. Under Tolpuddle thatched eaves the scaffold is set back and boarded so nothing rests on the thatch. On a roadside wall the footway has to be kept safe. Either way the platform stays up for every coat, and the work at height rules are why it is priced as its own item.
Finishing details. A bellcast at the base, beads at the corners, stop ends at openings and cutting around sills and pipework all add hours. Limewash on top is its own line.
When you compare, ask whether the old render is coming off or being covered, which system and how many coats, and whether the scaffold is included.
If it has started to come away
Render that has cracked, bulged or blown off
Ring us instead of using the form. A patch that sounds hollow when tapped, or a crack wide enough to take a coin, is letting water behind the render, and frost will push it off.
Cement render coming away from an old wall is worse than no render, because it traps the water behind it. On the first visit to a Tolpuddle house we take down anything loose over a path, sheet the area if the weather is bad, and then price the elevation once we can see how far the damage goes. Rendering work is booked Monday to Friday, 8am to 6pm. If you get no answer, we ring back as soon as we can.
Worth knowing
On these cottages the render is the historic finish
Render is easy to think of as decoration over the real wall. On the older buildings in Tolpuddle it is not. The wall was built to be covered, the covering was lime, and the lime was limewashed and renewed every few years as ordinary maintenance. That works because each layer is softer and more breathable than the one beneath, so water that gets in leaves through the face rather than through the plaster in your sitting room.
So when you are comparing quotes, ask what mix is going on and why. A modern coloured topcoat on a solid wall is the wrong job however good the price looks, and the damage does not show for three or four winters, by which time the money is spent. Ask whether the old render is being cut back to a firm edge or hacked off wholesale, because on a repairable wall the wholesale answer is wasteful. And on any building inside the conservation area, ask whether the appearance changes at all, because that is what the council will ask you.

Questions
Questions about rendering in Tolpuddle
What is wrong with cement render on an old cottage?
Cement render is harder and less permeable than the old cottage wall it is stuck to. Water still gets in at the top, at cracks and around openings, then cannot get back out through the face, so it goes inwards or freezes behind the coat. The render blows off in sheets and takes some of the wall surface with it.
Can a lime render just be patched?
Often, yes, and it is much cheaper than a full elevation. We cut back to a firm edge, dampen the background and work new lime in so it knits to the old. Where a third of a face has gone, patching stops being economic and a full coat is better value.
How often does limewash need doing?
Limewash lasts about five years on an exposed face, longer on a sheltered one. It is meant to wear, because that is how it protects the render underneath. Two or three thin coats renew it, and on a single storey wall it needs no scaffold.
Our cottage has masonry paint on it. Is that a problem?
Usually: modern masonry paint seals the face, and a solid wall needs that face open. If the render underneath is sounding hollow or the inside walls are damp, the paint is part of the reason. It can be taken off, and then the wall and the render need time to dry before anything is put back.
Do you work on listed buildings?
Yes, and we would rather see the consent in place first. On a listed cottage the render, the limewash and often the outbuildings are all covered. We put the specification in writing for the conservation officer, because taking cement off and returning to lime is usually welcomed, not resisted.
