Commercial Cladding Cleaning - Eurofins BLC, Northampton (NN3 6JD)

Eurofins BLC entrance canopy cladding after soft wash, Northampton NN3 6JD - clean cream-white finish under blue sky

On 13 May 2026, in just one visit, we completed a commercial soft wash and exterior cleaning job at Eurofins BLC (Leather Technology Centre), Kings Park Road, Northampton NN3 6JD. We had to clean the entrance canopy cladding, brickwork, windows and a roof parapet. The major point of attention was the sloped canopy, heavily stained by algae. Using a water-fed telescopic pole, we carried out all cleaning from ground level. We didn’t have to use a scaffold or powered access.

The project, in a nutshell

Client: Eurofins BLC (Leather Technology Centre)
Where: Kings Park Road, Northampton, NN3 6JD
When: 13 May 2026
Scope: Entrance canopy cladding, external brickwork, windows, roof parapet, brick paving
The access method: Ground level + water-fed telescopic pole
How did we do it: Soft washing (low-pressure sodium hypochlorite) + low-pressure rinse

The main issue

Eurofins BLC is an operational laboratory and testing facility. Therefore, we had to clean the building without disrupting reception, deliveries, or access to nearby areas. As for the contamination, we were not surprised. It was expected for a property left to weather. On the angled cladding over the main entrance, yellow-green staining covered the entire face. When you looked at the building, it was the first thing you saw.

Down the brickwork, vertical green staining from a downpipe was running down. Over the entire wall surface, rainwater had carried biological growth. The flat-roof parapet wasn’t any better. Along its top edge, dried moss and organic debris had accumulated in the gutter line.

All things considered, we had to use a specific approach for each surface material. The brown brickwork, corrugated metal cladding, brick paving and the glass curtain-wall entrance all needed a specific method. We didn’t want to damage anything.

What was our angle

We didn’t just start cleaning - better safe than sorry, they say - so we’ve run a test patch first. We’ve confirmed the wash-down approach against it. This vital step provides precise data on dwell time and dilution for the cladding finish before we start cleaning the elevation.

Using low pressure (fan spray), we’ve applied a controlled sodium hypochlorite solution. We covered the canopy cladding, brickwork and treated wall areas. Soft washing is a low-pressure method that doesn’t blast off algae and biological growth. Instead, it kills them at the root. This way, we protect the cladding finish and the panel joints.

Cleaning without dwell time doesn’t cut it. So, we’ve continued our job by waiting for the solution to work. Once dwell time was over, we rinsed down all surfaces at low pressure. This way, we managed to lift the dead organic growth, but didn’t push water behind the panels.

No building looks its best if its cladding is refreshed but its windows are dull and unsightly. So, we’ve cleaned all accessible windows along each elevation. Our teams used the water-fed pole. The entrance and side-façade window lines weren’t missed.

As for the downpipe streaking and surface contamination on the external brickwork, we’ve addressed them as well. In the end, they all presented an appealing, even tone. Our operatives took care of the parapet cladding and gutter line, too. They removed all algae and organic debris. On a section of brick paving and a mossy concrete slab, they concluded with pressure washing.

How we’ve left things

Remember the heavy yellow-green algae on the entrance canopy cladding? Now it was gone, and instead you could see a clean, cream-white finish. Algae from the roof parapet and debris in gutters were all gone, while the brickwork had an even tone, with no more downpipe streaking. Across the front and side elevations, window lines were clean, and everyone could see the original colour of the brick paving and the former mossy slab. On top of everything, we achieved all these results without damaging the cladding finish, glazing, or brickwork.

Project Images

Wide shot of the side facade with three tall windows, ADT alarm sign, brick and cladding showing visible weathering — Pre-clean view of the side elevation - the staining above the window line was concentrated where rainwater pooled along the cladding.

Wide shot of the main entrance with glass curtain wall doors below a sloped canopy heavily stained yellow-green — The reception approach before treatment - the angled canopy panel was the most visually striking contamination on the building.

Wide view of the side wall - brown brickwork below, continuous cladding band above, two pedestrians on the pavement — Scale shot of the side elevation - foot traffic continued throughout the day, which shaped how we sequenced the work.

Low-pressure soft wash solution applied to brick wall directly under the cladding band with downpipe visible — Soft wash means low pressure plus the right chemistry - the solution does the cleaning, not the jet.

Soft wash spray reaching a tall window and surrounding brickwork, a car visible reflected in the glass — Windows treated in the same pass as the elevation - a final pure-water rinse leaves the glass clear and streak-free.

Soft wash solution visibly running down a wide brick wall panel during the treatment phase — You can see the wash flowing down the elevation - dwell time matters more than pressure for getting algae out of brick pores.

Soft wash directed at the lower frame of a tall window where dirt accumulates against the brickwork — Lower window frames collect splash-back from the ground and need extra attention - generic cleans skip this and it shows.

Soft wash spray applied to the brick wall directly below the Eurofins BLC Leather Technology Centre reception plaque — Cleaning right up to the reception signage - the area visitors see first deserves the same care as the rest of the elevation.

Window line on the side elevation being soft washed below the yellow ADT alarm signage with brick and cladding — Side elevation worked methodically from one end to the other - no panel skipped, no streak left on the join lines.

Soft wash fan spray reaching the top edge of grey corrugated metal cladding above the brick wall — Reaching the cladding cornice from ground level - the water-fed pole keeps us off ladders for the whole elevation.

Soft wash applied at the base of the brick wall beside iris and yucca planting, a second operator partly visible to the right — Working carefully around ornamental planting - the soft wash solution is biodegradable so the borders stay safe.

Wider view of brick wall with white ventilation grille and downpipe being soft washed in a single pass — Grilles, downpipes and surrounding brick treated together so the elevation reads as one consistent tone afterwards.

Low-pressure rinse applied to the corner of the entrance canopy cladding with water droplets visible spraying away in the air — Rinse phase on the canopy corner - low pressure lifts the dead organic growth without pushing water behind the panel laps.

Telescopic pole with a red brush head completing finishing touches on the porch cladding underside — Final brush pass for stubborn lichen specks the spray alone wouldn't lift - the difference between clean and properly clean.

Flat bitumen roof with white parapet cladding showing green algae patches above and dried moss debris in the gutter line — Up on the flat roof - the parapet had been quietly collecting wind-blown moss and seed debris for years, out of sight.

The same flat roof parapet after cleaning - algae patches gone, gutter debris cleared, surface still wet from the rinse — Same parapet after a single pass - debris cleared from the gutter line and the painted cladding back to its original tone.

Brick paving path mid-clean - rotary surface cleaner pressure washing one section with a clear split between cleaned and dirty — Brick paving cleaned with a rotary surface cleaner - even pressure across the surface keeps the joint sand in place.

Large concrete paving slab beside a side door with dense green moss colonising the gravel border around it — A particularly mossy slab by the side door - shade and a damp gravel border made it a perfect spot for growth.
