Specialist Render Cleaning with DOFF Steam Technology

Acrylic pre-mixed renders have seen a surge in popularity among builders and developers over the past decade. These modern coloured renders are more durable and water-resistant than traditional sand and cement finishes. Their breathable, textured surface offers long-lasting performance—but also creates the perfect environment for moss, algae, and other organic growth, especially in the damp and variable British climate.

Over time, this biological matter can lead to unsightly green, black, or yellow staining that not only detracts from the building’s appearance but can also reduce the lifespan of the render if left untreated. Early intervention is key.

Why High Pressure Is Not the Answer

It’s important not to use high-pressure washing on coloured or acrylic renders. The force of high-pressure water can strip away the surface, damage the finish, and lead to costly repairs. Instead, we use the DOFF steam cleaning system—a highly effective method that combines low pressure with high-temperature steam to gently but thoroughly clean render surfaces without causing any damage.

The DOFF system is especially effective at:

Removing moss, algae, and lichen
Lifting stains caused by pollution or organic growth
Preserving the integrity and colour of modern render finishes

 

Softwash Treatment for Long-Term Results

In addition to steam cleaning, we also offer softwash render cleaning—a process that applies targeted biocidal treatments to eliminate spores and prevent regrowth. This can involve:

Fungicidal washes to kill off algae and mildew
Bleach-based biocides for faster results where needed

Both approaches are safe for use on all modern render types and provide long-lasting cleanliness with minimal disruption.

What Our Clients Say About Us

Efficient and tidy
This company is fantastic from all the staff in the office to the surveyor. Lee and Shawn who did a very good job with the cavity wall insulation, they arrived on time and left our property clean and tidy.
Arrow Insulation carried out a free survey using a cavity camera and found I already have good cavity insulation and no work is required. They explained clearly about the insulation I have and that it is common in houses built circa 1993. Very friendly and business like.
I'd like to say Arrow Insulation were amazing. Today I had my cavity wall filled, Dan and Frank were very professional, arrived at the scheduled time, polite, clearly explained the process and set expectations. After the insulation everything was clean, clear and tidy. Dan walked around the property with me while we looked at the work carried out and answered any additional questions I had.

Thank you so much for both the extraction and insulation teams doing their work to a very high standard. Waiting for it to be winter now to feel the benefits of the cavity wall insulation.

I would highly recommend Arrow Insulation to everyone looking at cavity wall insulation. Thank you 🙂
I used Arrow for both cavity wall extraction and cavity wall insulation. The installation was great, the guys were very fast, turned up on time and the communication was great, they were generally tidy and did a good job. I had a few issues with the extraction because of a surveryor, but the team sorted it out fairly quickly and managed to do the job. I would use them again.
Cavity wall insulation. Dan and Frank arrived at the specified time and were very polite and professional. I think it may have been Frank's first day as Dan was clearly in charge and between them they did a fantastic job :). Over and beyond.
Cavity wall extraction and installation of bead insulation. Excellent service and whilst an unknown hole in the kitchen wall meant a considerable amount of dust that required 3 hours of cleaning by me this was unforeseen. Looking forward to now seeing the benefits of new wall insulation!
Arrow installed cavity wall insulation to our property. They conducted a thorough survey and provided an informative report detailing the work to be done. Their price appeared to be competitive. The installation was brought forward by a week-or-so. The on-site team arrived late, due to weather issues. With work like this you can't really tell whether it has been done properly. However the on-site team were very professional and enthusiastic. They explained what they were doing, appeared knowledgable and tidied up the site afterwards. They were a good advertisement for the company.
Frank & Dan came today to carry out our cavity wall insulation, they were both really friendly & courteous throughout. They arrived slightly earlier as I had to leave to do the school run so that was really appreciated. After the work was carried out they cleared everything up & I would highly recommend these 2.
The company itself were friendly, professional & quick at responding to queries & booking the appointments. Definitely a company you can trust. Thanks!
