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.

Will cleaning damage old stonework?

Not with the method we use. Historic stone gets a soft wash with a biocide and a rinse, never a pressure lance, because pressure opens up the face of soft stone.

The render goes back to its original colour without etching the surface or damaging the bead lines.

render cleaning in Kenilworth, what we actually find here

The housing round here. A blend of older stone and brick around Castle End and Abbey Fields, 1930s semis along the Warwick and Coventry roads, and modern detached estates towards Mill End.

Why Kenilworth exteriors get dirty. The green corridor around Abbey Fields keeps things damp and shaded, so moss on roofs and slippery green film on north-facing paths are the usual complaints.

Access and pricing. Older stone boundary walls and gravel drives need care with run-off, so we contain and direct water rather than letting it wash the gravel about.

Covering CV8, including Castle End, Abbey Fields, Mill 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.
