Rendering in Winterborne Kingston, wet ground

Tapping the elevation comes first. A hammer handle over the wall separates render that is still bonded from render that has blown. Around Winterborne Kingston the hollow band runs along the base, sometimes the full width of a house, and it is always wider than the crack that made you ring.

The base detail. On a Winterborne Kingston house, render should stop on a bellcast bead above the damp proof course with a visible gap under it, so water is thrown clear instead of running back behind. Where a previous job has taken the render straight down into a path or a border, it has bridged the damp course, and correcting that is the first thing on the list rather than an optional extra.

Hacking off and rebuilding. Blown render on a Winterborne Kingston wall comes off back to sound masonry. Loose joints are repointed, the background cleaned down and stabilised where it is dusty, then a mesh reinforced basecoat and the finish in coats. A damp wall needs time between coats and we build that into the programme.

Lime on period solid walls. The pre-1919 Winterborne Kingston cottages have solid walls with no cavity, built breathable so moisture soaks in and dries back out through the face. On wet ground that drying route matters more, not less. Lime keeps it open, moves with the wall and can be patched. A plastic rich modern system traps the moisture and pushes it inside.

Silicone thin coat and monocouche. Good systems on a modern cavity wall, which is what the newer houses in Winterborne Kingston are. A stabilising primer where needed, a mesh reinforced basecoat, then a through coloured topcoat that sheds water and needs no painting. Both still want the base detail right, because no topcoat fixes a bridged damp course.

Sand and cement, pebbledash and Tyrolean. Scratch coat, float coat and dash where the elevation already carries it. Patches are matched to a sample panel where the aggregate is still obtainable, and where it is not we say the repair will read differently.

Beads and movement joints. Bellcast at the base, stop beads at reveals and eaves, angle beads on corners, and a movement joint where an elevation is long or two structures meet. A joint put in deliberately saves a crack appearing where it chooses.

External wall insulation. Board fixed outside and rendered over, on a render carrier where the background will not take a direct fix. On wet ground the base track and the ground clearance matter more than usual, because insulation sitting in a damp border stays damp.

Cracking, algae and staining. Straight hairline cracks are shrinkage, stepped cracks are movement. Green low down on a wall is a symptom of the damp band rather than a cleaning problem, and treating it without fixing the base books a repeat visit.

The area of wall is the easy part. What is already on it, and what it stands in, sets the price.

Tapping the wall. Sound render over good brick can be repaired or overcoated. Blown sand and cement, or pebbledash parting from the background, has to be hacked off, and nobody can see that from the road. We tap every elevation before quoting, and the hollow areas set most of the hours.

The bottom of the wall. Render carried down into the soil or onto a path wicks water up. A proper bellcast above the damp course, with a clean gap at the base, is the detail that stops it. On soft or wet ground the scaffold footings have to be spread properly too.

The system. Sand and cement, monocouche, silicone thin coat or lime all cost and behave differently. On a solid wall that needs to breathe, a hard or plastic-rich modern render traps damp and moves the problem inside. The wall picks the system, not the colour chart.

Access time. A scaffold that stands for the full system is priced under the work at height rules.

Ask another quote which system and how many coats, whether they hack off or overlay, and whether beads, bellcast and stop ends are included.

A winterbourne is a chalk stream that runs only when the water table has risen far enough to reach the surface. It fills through the autumn, runs all winter and disappears in the summer.

The stream is only the visible part: under the village the water table does the same, so from November to May the ground beside your walls holds water even in a dry week, and the flood risk service shows how much of Winterborne Kingston is on that ground.

For render, that turns two ordinary details into the important ones. First, the ground level. Every border, path or bed that has crept up the wall over the years shortens the gap above the damp proof course, and once the ground is above it the barrier is bypassed. Second, where the render stops. A bellcast bead with clear air under it lets the wall shed water; render taken down to the soil gives it a hard route straight into the masonry. Get those two right and an ordinary system will last here. Get them wrong and it does not matter what you spend on the topcoat.
