Render & K-Rend Cleaning
Removing green, red and black algae staining from rendered properties without the need for aggressive pressure washing.
The Deep Clean Team – Tough on Stains, Gentle on Surfaces!

Here at The Deep Clean Team, we specialise in professional chemical washing and soft washing for those stubborn stains and delicate surfaces that simply cannot be cleaned using traditional high-pressure jet washing.
Not every surface can withstand the force of a pressure washer, and not every stain can be removed with water alone. That’s where our specialist chemical cleaning services come in!
Using professional-grade cleaning solutions, specialist biocides and carefully selected treatments, we can tackle years of built-up grime, algae, moss, lichen and stubborn staining while protecting the surfaces underneath.

Some exterior surfaces are simply too delicate for high-pressure cleaning. Using excessive pressure can damage render, remove protective coatings, erode brickwork, disturb pointing and force water into places it shouldn’t go.
Our chemical washing methods work differently. Rather than relying on water pressure alone, we use specialist cleaning solutions designed to break down or treat contamination, allowing surfaces to be cleaned using much gentler methods.
Have you got stubborn black spots on your patio? Green algae covering your render? Unsightly staining running down your brickwork?
Our specialist chemical cleaning treatments may be able to dramatically improve its appearance, even when conventional jet washing has failed.
Every surface is different, which is why we assess the material, its condition and the type of staining before selecting the most suitable cleaning method.
We always aim to achieve the best possible results without causing unnecessary damage.
At The Deep Clean Team, we take pride in our attention to detail, professional equipment and years of exterior cleaning experience.
We are fully insured and understand that the correct cleaning method is just as important as the finished result.
