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.

Do you do the drive and the render on the same visit?

Yes, and combining them is cheaper than booking two separate visits because the setup is shared.

How long does a large block drive take?

Most take the best part of a day including re-sanding. We give you a realistic window when we quote rather than an optimistic one.

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.
