Render Cleaning: Done Right
Our team knows how to clean the render of your home safely and effectively without causing any damage. We’ve seen cases where homeowners or contractors have tried to clean the surface using the wrong methods, and sadly, many have ended up damaging it. It’s important to take great care to protect your render throughout the cleaning process.
Our Process
Newly rendered properties look amazing, but over time, they can get stained by algae. These stains can be green, black, or even red. After deep cleaning to remove all those colorful algae stains, we suggest an annual maintenance treatment to stop spores from building up again. Some parts of the building, especially those without much sunlight or near trees, can stay damp and start growing new algae. This is common with render, but we can easily prevent it with our safe and proven methods and maintenance plan.
Painted render surfaces
Sometimes when they get dirty or covered in algae, people just paint over them again. But if you paint over living things like algae, the paint might not stick well or the algae could still show through. Cleaning the surface before painting not only gives you a clean surface to paint on, but it also gets rid of any dirt, so the paint sticks better. This means the paint will last longer and look better right from the start.

Chemical Treatment for Render Cleaning
One of the common issues with render cleaning is the recurring problem of organic growth shortly after the cleaning process. At Blue Whale SWS, we use bio-
degradable chemicals that are safe for the environment to treat and eliminate organic matter spores at their source.
This ensures that you won’t have to deal with organic growth again soon after cleaning. Our chemical treatment approach ensures that the results of our cleaning
services last four to six times longer than typical pressure washing methods. This is because we treat the root of the organic matter problem, rather than just dealing with the surface elements that pressure washing can address. While homeowners may use their Karcher to pressure wash render, this may not always yield the best results, which is why it’s best to contact a professional like Blue Whale SWS.
When booking your render cleaning, it’s the perfect time to consider additional services that enhance your property’s appearance and protection. Alongside removing dirt and stains from your render—whether mild or heavily soiled—we also offer a comprehensive package that includes clearing out your gutters and cleaning your soffits and fascia boards. These areas often collect dirt and algae over time and cleaning them alongside your render not only boosts curb appeal but helps prevent long-term damage and costly repairs. Bundling these services ensures a cleaner, fresher-looking exterior—and better value overall.
The cost of render cleaning can vary, so we recommend a home assessment to determine all the additional services required before confirming a fixed price.

Render FAQ’s
How do you get up to the top part of my property?
Most two-story homes can be cleaned from the ground level, its larger homes or townhouses that we may need to apply the treatment from an extension pole or cherry picker.
We always recommend a home assessment is carried out just to be sure.
As long as we can park a large van on your driveway, we can use a cherry picker which is the safest option.
Our team is fully trained to use this equipment and have all the safety gear they will need to ensure no one is put at risk.
What will the render look like after the job?
The chemical will continue to work over time, continually brightening and reactivate as the surface get wet. So it will look a lot cleaner but as the song goes, ‘Things can only get better’
