Render & Exterior Cleaning

The front of your property is
the first thing anyone sees.

Rendered exteriors are common across Hertfordshire — from the K-rend and monocouche finishes on newer builds to the older sand-cement render on 1970s and 80s properties. All of them discolour over time. Green algae, black mould and pollution staining build up on north-facing and sheltered elevations particularly quickly, and in Hertfordshire’s damp climate it can take hold within a season or two.

Render cannot be cleaned with high-pressure jet washing — the surface is too fragile and high pressure forces water behind the render, causing bubbling, cracking and long-term moisture damage. St Albans Jet Washing uses professional soft wash techniques — low pressure combined with specialist biocide cleaning solutions — to remove all organic staining effectively and safely across St Albans and Hertfordshire.

Soft wash

Our technique

Low pressure — safe on all render types

Surfaces we clean

Every render type, cleaned
the right way.

Different render types need different approaches. We identify the surface first and always use the safest, most effective technique for that specific finish.

01

K-rend & monocouche
The most popular modern render in Hertfordshire. Textured surface traps algae quickly. Must be soft washed — high pressure will damage the finish.

Most common

02

Sand-cement render
Common on 1970s–1990s properties. More robust than modern thin coats but still requires careful soft washing to avoid dislodging or cracking.

Older properties

03

Pebbledash
Heavily textured and porous. Algae hides deep in the surface and needs thorough biocide treatment to fully remove.

Common in Borehamwood & Hemel

04

Tyrolean render
Roughcast textured finish common on inter-war properties. Needs low-pressure treatment to avoid dislodging the aggregate.

Careful approach

05

Painted render
Painted or colour-coated render needs extra care to avoid stripping or dulling the finish. We use the appropriate pressure and solutions throughout.

Colour preserved

06

Brick & stonework
External brickwork and natural stone elevations cleaned safely using appropriate techniques. We assess every surface before starting.

Also available

Everything is included.
Nothing gets added on the day.

No surprises, no upsells. What we quote is the full job.

Biocide pre-treatment

A specialist biocide is applied to the surface and allowed to dwell before washing begins. This kills algae, mould and lichen at the root — not just on the surface — for longer-lasting results.

Low-pressure soft wash clean

We use low-pressure soft washing throughout — never a high-pressure lance on rendered surfaces. This safely removes all organic staining without risking damage to the finish.

All elevations covered

We clean all affected elevations of the property — not just the front face. Side walls and rear elevations are included if they need attention, at no extra charge.

Full rinse and clear-up

Once the clean is complete we rinse everything down and leave the area completely tidy. Any run-off from the clean is cleared from surrounding surfaces, windows and paths.

Common questions about
driveway cleaning in Hertfordshire.

Common questions about our render and exterior cleaning service across St Albans and Hertfordshire.

How much does render cleaning cost in St Albans?

Our render cleaning starts from £69 across St Albans and Hertfordshire. The final cost depends on the size of the property and the number of elevations being cleaned. We always confirm the full price before any work begins — no surprises on the day.
High pressure forces water behind the render surface, causing bubbling, cracking and moisture ingress — which is far more expensive to fix than the algae was. Soft washing at low pressure with specialist biocide solutions is the only safe and effective method for rendered exteriors. We never use high pressure on render.
A professional soft wash clean typically keeps a rendered exterior clean for 2–4 years, depending on aspect and local tree cover. North-facing elevations in sheltered positions may need attention sooner. The biocide treatment continues working after the clean, killing algae spores as they regrow.
Yes — K-rend and monocouche finishes are some of the most common renders we clean across Hertfordshire. Both are soft washed using appropriate solutions. The textured surface traps algae deeply, so thorough pre-treatment is particularly important. We include this as standard.
We take care to protect windows and surrounding surfaces throughout the clean, and rinse everything down on completion. Any run-off from the biocide solution is cleared from paths, patios and planted areas before we leave.
