How do you clean K-Rend?

Soft wash only. Apply a sodium-hypochlorite based biocide at low pressure, let it dwell, then rinse with pure water at low pressure. Never use a jet wash, it ruins the silicone finish and opens the surface to water.

Can you clean monocouche render?

Yes, same soft-wash method as K-Rend, with biocide dilution tuned for the through-coloured surface. Pressure washing monocouche pulls colour out and shows immediately.

How much does render cleaning cost?

Most semi-detached homes are £180,£450 depending on render area and access. Detached homes with full wraps run £450,£900.

Will the algae come back?

Most properties stay clean for 3,5 years. Shaded, north-facing or tree-lined walls are quicker to regrow, we offer a top-up biocide spray every 2 years on a maintenance plan.

Will it damage my windows or plants?

No. The biocide is plant-safe at our dilution; window frames and gutters are rinsed clear before we finish.

Can you clean K-rend without damaging it?

Yes, and pressure washing is exactly what you must not do to it. K-rend and similar through-coloured renders get a low-pressure soft wash and a dwell treatment, which lifts the algae without scarring the finish.

My gutter is shared with next door, what happens?

We inspect the run with a camera first. If the blockage sits over your neighbour's section we will tell you and show you the footage rather than charge you for work that will not fix it.

Render cleaning in Nuneaton starts from £180 and uses soft-wash methods only, never a pressure washer on modern thin-coat render. We treat algae, red lichen and black streaking on K-Rend, monocouche and silicone systems with a controlled biocide and pure-water rinse. The render goes back to its original colour without etching the surface or damaging the bead lines.

render cleaning in Nuneaton, what we actually find here

The housing round here. Dense terraced and semi-detached streets in Stockingford and Attleborough, larger family housing at Weddington and Whitestone, and a good amount of modern rendered and K-rend housing on the newer developments.

Why Nuneaton exteriors get dirty. The rendered estates around Whitestone and Weddington show algae early because modern render holds moisture on the surface, and the older Stockingford terraces suffer more from blocked gutters and moss on low roofs.

Access and pricing. Terraced rows often share guttering across several properties, so we tell you honestly when the blockage is next door rather than over yours.

Covering CV10, CV11, CV12, CV13, including Weddington, Whitestone, Stockingford, Attleborough, Chapel End.

Why professional render cleaning matters

Modern thin-coat render, K-Rend, Weber, Parex, Wetherby, is sensitive. Pressure washing scours it, opens the surface to water ingress and ruins the finish. The right method is soft wash: a biocide that kills the algae and red lichen at root, followed by a gentle rinse. The render returns to its original colour over a few weeks as rain carries the dead growth away.
