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 re-sand block paving after cleaning?

Yes, kiln-dried sand is brushed back into the joints as standard on block paving, which is what keeps the blocks locked and slows weed return.

Can you clean a conservatory roof at the same time?

Yes. Conservatory roofs, frames and finials are done from the ground with a soft brush and pure water, and it is far cheaper booked alongside another job.

Detached and executive homes a speciality, fully insured, neat, no mess left behind.

Render cleaning in Solihull 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 Solihull, what we actually find here

The housing round here. Larger detached and executive homes across Olton, Shirley and the B91 and B92 belt, plenty of block-paved sweeping drives, double garages and conservatories.

Why Solihull exteriors get dirty. Mature tree-lined roads drop a lot onto roofs and into gutters, and the big block-paved drives here show sand loss and weed growth long before the blocks themselves wear out.

Access and pricing. Bigger plots mean longer hose runs and more careful protection of planting and lighting, which we allow for in the quote rather than adding on the day.

Covering B90, B91, B92, B93, B94, including Shirley, Knowle, Dorridge, Olton, Hampton-in-Arden.

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.
