Rendering in Alderholt, specified for the wall

Tapping the wall comes first. Nothing in Alderholt gets priced until the elevation has been sounded out. Render that is still bonded rings hard; render that has parted from the background sounds hollow and drummy. The hollow area is nearly always wider than the crack that prompted the call.

Hacking off and rebuilding. Blown render on an Alderholt wall comes off back to a clean sound background. Loose joints behind it are repaired, a stabilising primer goes on where the surface is dusty, then a mesh reinforced basecoat and the finish. New render laid over a hollow wall is one of the commonest faults on an old elevation, and it fails from underneath.

Silicone thin coat. The right answer on the 1980s cavity walled houses in Alderholt. Through coloured so a chip does not show white, applied thin over a reinforced basecoat, flexible enough to take small movement, and it washes down. On a cavity wall the breathability question does not bite the way it does on solid masonry.

Monocouche. A single through coloured coat applied thick, ruled off and scraped back to a fine even texture. Hard wearing and needs no painting. It wants a stable background and planned day joints, so we decide where each day's work stops before the first mix is made.

Sand and cement, pebbledash and Tyrolean. Traditional scratch and float coats, and dash repairs where the elevation still carries it. Much of the dash in Alderholt is forty years old and shedding, and the honest choice is between patching the worst of it and taking the wall back to brick.

Older solid walls. A fifth of the housing in Alderholt predates 1919. Those are solid walls, built breathable, designed to take moisture in and let it dry back out through the face. Wrap one in a plastic rich modern render and the moisture is trapped, so it comes out on the inside instead. Those walls get lime, which stays open and moves with the period fabric.

Extensions and making good. Joining a rear extension to an existing rendered house is fussier than rendering either alone. The two backgrounds move at different rates, so a movement joint goes in at the junction and mesh is carried across the change of material.

External wall insulation. Board fixed to the outside and rendered over, on a render carrier where the background will not take a direct fix. It thickens the wall, so sills, reveals, eaves, vents and downpipes are all reworked as part of the job.

Cracking, delamination and staining. Straight hairline cracks are usually shrinkage in the render. Stepped or widening cracks are movement behind it and want investigating first. Green on a shaded elevation is a wash and a treatment; a topcoat that comes off on your hand is a recoat.

Render is priced from what we find when we tap the wall, not from its area. Hollow render. Old sand and cement or pebbledash that has parted from the brick sounds dead when tapped. It all has to come off, back to a sound surface, before anything new goes on, and you cannot see it from the road.

Scaffold. In Alderholt, a detached house with open ground round it is simple. A semi with a narrow side passage or a cottage tight to the lane is not, and the scaffold stays up through every coat. HSE guidance sets how it is built.

Which system. A traditional sand and cement render, a through-coloured monocouche, or a silicone thin coat over insulation board each cost and behave differently. The Alderholt cottages with solid walls need something that lets them breathe, usually lime, because a hard plastic finish traps damp and pushes it indoors.

Details. Beads at every corner and window, a bellcast over the damp course, stop ends, and taking pipes and sills off and back again all add up.

Worth asking anyone else: what system, how many coats, is the old render coming off, and is the scaffold included?

On most of the villages around Alderholt the planning position does some of the thinking for you. A conservation area or a listing forces a conversation about materials before anything comes off the wall, and that conversation catches a lot of bad specifications by accident.

Here there is no conservation area, and listing covers only a few buildings, the Church of St James among them. Check the Historic England list for your own address. A like-for-like repair is maintenance, but render on bare brick or a clearly different finish often needs an application.

That is fine if you want a through coloured render that keeps the look of a 1980s house, and a trap on an older one. The wall does not care about the planning position. A solid pre-1919 wall behaves the same here as it would inside a conservation area: it needs to breathe, and a plastic rich system traps moisture and moves the damp indoors. So the question to ask whoever quotes is not only whether you are allowed. It is what the wall is made of and why their system suits that background.
