Paving, step and brick edging in Radlett after cleaning and repointing, with planters and lawn beyond
What we do

Drives and patios first, walls too

Most of our work in Radlett is driveways and patios – block paving, resin-bound drives and natural stone terraces cleaned back to their original colour, with the joints treated so the weeds don’t come straight back.

We also soft wash render, painted walls and brick across Radlett. Render, paint and older brick won’t take high pressure without damage, so walls are cleaned with a low-pressure biocide instead. If they’ve gone green on the shaded side, we can do them on the same visit as the drive.

Method

What actually happens on a soft wash

A foamy biocidal chemical is applied by pole at low pressure, so it clings to the wall instead of running straight off. It is left to work, killing the algae and black mould rather than knocking the surface layer off, and then rinsed down, again at low pressure. Nothing about it is forceful.

The reason matters. A jet gun on render cracks the finish and pushes water in behind it, and on painted walls it takes the paint with it. What looks clean on the day turns into a repair bill later, and it comes back faster because the organic growth was never killed, only washed off the surface.

The same thinking applies to old brick and stone: treat, wait, rinse gently. Where a surface genuinely needs pressure, such as a block-paved drive, it gets pressure. Matching the method to the material is most of the job.

Yes, and it is common here, because the two methods use different equipment but the same visit. The walls are treated and left to work while the paving is cleaned, which is a better use of the day than two bookings.

It is low-pressure cleaning for render and exterior walls. A biocidal treatment is put on by pole, left to kill the algae and black mould at the root, then rinsed off gently. No high pressure touches the wall at any point.

No. Those finishes are exactly why the method exists: they are cleaned by treatment and a gentle rinse rather than by force, so the texture and colour stay as they are. It is high-pressure jetting that damages them.

Yes. The treatment is applied by pole from ground level, and our poles reach the third storey, so most houses need no scaffolding or towers. If the access is tricky, we arrange access hire through a company we use.

Soft washing kills growth at the root instead of stripping it off the surface, so it stays away considerably longer than jetting – at least four to five years in most cases.

No. We clean render, walls, brick, stone and hard surfaces only. Roofs, gutters and conservatories are outside what we do, and we would rather say that now than waste your time.

It is priced on the elevations to be treated, the height, the access and how far the growth has gone, not by the square metre. The minimum charge is £250 and there is no VAT. Photos of each affected wall on WhatsApp will get a price back, usually the same day.
