Full House Render Cleaning in Northampton (February 2024)

Our February 2024 portfolio includes, among many jobs, cleaning a full house render for a residential property in Northampton. The job took place in February, and we had to remove green algae from the render. Across several elevations, the render showed general weathering stains, and the whole property looked discoloured and unsightly. To clean all elevations, we turned to soft wash methods. The client received a render restored to an even, clean finish.

The project, in a nutshell

• Where: Northampton
• When: February 2024
• What was the property type: Residential
• The main issue: Green algae and weathering
• Method: Soft wash + rinse

The Challenge

Remember that we mentioned that the job took place in February. This means that we had to deal with shorter daylight hours and cooler temperatures. They both deeply affect dwell times and drying. Our goal was to deliver a thorough result, and we had to tailor the schedule to the reduced working hours.

The render didn't show just the typical shaded sides you'd expect with weathering; it went well past that. Algae had developed across all elevations of the property. You could see the green growth from everywhere: front, side, and rear- you name it. For a consistent finish, we had to treat all surfaces. As the render surface is textured, the pressure had to be carefully controlled. Our team had to clean without damaging the finish or pushing water behind the render layer.

How we addressed the challenge

Across all affected surfaces, we applied a cleaning solution at low pressure. This softwash method breaks down algae and biological growth but doesn't pose the risk of damage that high-pressure does. Dwell time can never be missing from this sort of job. The cleaning solution needs time to break down the organic growth. Imagine the February temperatures. We definitely needed to adjust dwell times to make sure that the treatment gave the most effective results.

Working from the top down, we meticulously rinsed every elevation so that dirty water wouldn't streak across already-cleaned areas. Anyone looking for even, streak-free results should know that the top-to-bottom approach is vital.

Whenever necessary, we even cleaned by hand. Door surrounds, areas around window frames, soffits — these sorts of areas. Such detail areas tend to collect the most obvious staining and runoff marks. That's why we never skip corners around them.

The outcome?

We restored the render to a clean, even appearance. Yes, across all elevations. The green algae and weathering stains were completely gone. No matter which angle you looked from, the property looked brighter, fresher, and more appealing.

Before and After

See the before-and-after photos in the project gallery below. You will see how the render looked before and after our treatment. The most visible difference is on the elevations with the heaviest algae coverage. Impressive, right?
