Rendering in Hyde, inside the national park

Tapping comes first. On a Hyde wall, sound render rings hard, blown render sounds hollow and drummy. We go over every elevation and mark the edges of the hollow areas, because they are always larger than the crack that prompted the call and they decide the price.

Hacking off and rebuilding. Where the render on a Hyde house has parted from the background it has to come off, back to clean sound masonry. Loose joints are repointed, the background is prepared and stabilised where it is dusty, then the new system goes on in coats.

Lime render on solid walls. A pre-1919 wall has no cavity and was built to take moisture in and dry it back out through the face. Lime keeps that route open. It goes on as a hair reinforced scratch coat with a good key, a float coat, then a finish or a limewash, and it is kept damp and sheeted while it carbonates.

Getting an old cement render off. The commonest fault on the older Hyde cottages is a hard cement skin put on decades ago. It cracks, water gets behind, and the cement will not let it back out, so the wall stays wet and the salts and frost do the damage. It comes off by hand, patiently, never with a breaker.

The bottom metre of the wall. Surface water sits about in Hyde after heavy rain and the ground stays soft, so splash back keeps the base of an elevation wet long after the rest has dried. That is where the blown areas start. A bellcast bead above the damp proof course with a clear gap under it, and ground kept low, does more for a render than any topcoat.

Sand and cement, pebbledash and Tyrolean. Ordinary work on the twentieth century houses out in Hyde. Scratch coat, float coat, dash or Tyrolean where the elevation already carries it, matched to a sample panel where the aggregate is still available.

Silicone thin coat and monocouche. Both are good on a modern Hyde cavity wall: a stabilising primer, a mesh reinforced basecoat, then a through coloured topcoat with no painting afterwards. Both are wrong on a breathable solid wall, and in a conservation area the texture and colour have to be agreed before they are ordered.

Beads and stop ends. 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. On older fabric we hand form the arris instead, because a hard bead in a soft wall gives the render an edge to crack against.

External wall insulation. Board fixed outside and rendered over, on a render carrier where the background will not take a direct fix. It raises the thermal performance without losing a room, but it thickens the wall and changes every reveal, so on a designated frontage it is rarely the answer.

Measuring the wall is simple. What is on it already sets the price. Scaffold. On a soft verge, the scaffold footings need thought. Open ground by a farmhouse takes a plain scaffold. A two storey wall with a lean-to roof against it needs that roof protected first. Access is quoted separately under the work at height rules.

Stripping. Rendering onto sound brick in Hyde is one job. Where old sand and cement render is blown, or pebbledash has let go of the wall behind, it all has to be hacked off first, and there is no telling which from the lane. Every elevation is tapped first.

The render. Silicone thin coat over insulation, through-coloured monocouche, and traditional sand and cement are priced differently. A solid wall that has to breathe usually wants lime, because a plastic-rich system holds moisture in and drives damp indoors.

Near the ground. Render taken down into the soil wicks water up. A bellcast above the damp course, with a gap left beneath, is part of doing it right.

Ask other renderers which system and how many coats, whether beads, bellcast and stop ends are in, whether the old render is removed or overlaid, whether scaffold is priced in, and what happens to sills and pipework.

Most people assume the district council handles their planning. Inside the national park boundary it does not. The National Park Authority is the planning authority, it has its own policies, and it takes a closer interest in how buildings look than a district authority would on an ordinary estate. On top of that the Western Escarpment conservation area covers this side of the forest, which controls external appearance in its own right.

What that means for a Hyde render job is straightforward. Check the boundary before you choose anything, because the Park publishes an interactive property map that shows what applies to a given address. Expect the material, the texture and the colour all to be relevant rather than just the colour. Allow time in the programme for a decision if the finish is a change rather than a repair. And where the wall only needs its existing finish repaired, say so clearly, because a like for like repair is maintenance and does not need any of this.

We work from a base in Boscombe, 12.7 miles from Hyde, and render across the hamlets here, Frogham, Godshill and the lanes towards Fordingbridge, broadly SP6. The Park Authority handles planning, and your contract would be with Bournemouth Roofing & Building Ltd, registered in England and Wales, company number 15471719. Before you book a visit in Hyde, you can read our customers' Google reviews, word for word, on our reviews page.

Thomas Hannen owns and runs it, and he taps the walls and prices the render himself. One verified customer gave the firm 10 out of 10 on Checkatrade. Visiting costs nothing, and the written quote with each item set out is free too.

Most repairs in Hyde need no application at all. What decides whether a change to the outside of your house does is who the council is, whether a conservation area or a listing applies, and whether the place sits in a protected landscape.
