External rendering in Teesside
External rendering in Teesside costs £40 to £70 per square metre in 2026, which puts a single gable around £1,200 to £2,500 and a full semi at £4,000 to £8,000. Sand and cement, monocouche and through-coloured silicone systems, scaffolded and finished coat by coat.
The coat that takes the weather
Render is the only plastering that has to survive a north-easterly coming in off the North Sea. On the strip from Seaton Carew through Redcar to Marske and Saltburn, salt and driven rain work at a wall constantly, and render that was fine inland fails early here. Inland, the enemies are different: frost getting into a crack, a leaking gutter feeding one patch year after year, and the old habit of rendering straight over a damp solid wall with a dense mix that traps the moisture in.
The systems and what they cost
- Sand and cement, painted: the traditional and cheapest route, at the lower end of the range. Durable, repairable, and it needs a masonry paint every ten years or so.
- Monocouche: a one-coat through-coloured system applied thickly and scraped back. Mid-range on price, no painting afterwards, sharp modern look.
- Silicone thin-coat over base and mesh: the top of the range. Flexible, breathable, self-cleaning to a degree, and the usual choice for exposed coastal elevations.
- Lime render: the right answer on older solid-wall and listed property, including parts of Yarm High Street and the Saltburn conservation streets, where a breathable coat keeps moisture moving out rather than sitting in the brick.
- Pebbledash and roughcast repairs: patching and matching on the interwar estates where a full re-render is not on the cards yet.
What moves the price
Area, height and access set the base. A single-storey rear extension is straightforward, a two-storey gable needs a scaffold, and the scaffold is often quoted separately, so ask whether it is inside the figure or not. Preparation is the other half: hacking off old failed render and carting it away is a genuine day or two of work on a full house. Beads, stop ends and drip details around windows, doors and the roofline take time and are the parts that decide whether the finish still looks sharp in five years. Colour and texture choice sit on top of that.
Signs your render is going
Hollow patches when you tap it, hairline map cracking across a whole elevation, dark damp patches that never dry, and blown areas at the base where the render has been bridging the damp course. On the older Redcar and Hartlepool stock, look at the bottom metre first, because that is where salt and splash-back do their work. Patching is often perfectly reasonable and cheaper than a full re-render, and an honest quote will say when patching is throwing money at a wall that needs stripping. Interior work after a leak is covered on the plaster repairs page.
