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 black spots come off my concrete drive?

Black spot is lichen and it does not shift with pressure alone. It needs a chemical treatment, and it usually takes a few days after treatment before it fully releases.

Is there a travel charge inside CV12?

No. Bedworth is on our doorstep, so it is local pricing with no callout fee.

Render cleaning in Bedworth starts from £180 and uses soft-wash methods only, never a pressure washer on modern thin-coat render.

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

render cleaning in Bedworth, what we actually find here

The housing round here. Largely post-war and interwar semis with a strong core of former mining terraces around Collycroft and Goodyers End, plus newer infill development towards Exhall.

Why Bedworth exteriors get dirty. Older concrete and flagged drives here hold black spot lichen badly, and the low-pitch roofs on the post-war stock are prone to moss on the north slope.

Access and pricing. Rear access is usually straightforward through side gates, which keeps the job quicker and the price lower than on terraced streets.

Covering CV12, including Collycroft, Goodyers End, Bulkington, Exhall.

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.
