Frequently Asked Questions
Common questions about biocide treatment
What is biocide treatment and how does it work on render?
Biocide treatment is a professional-grade solution that kills organic growth (algae, moss, lichen) and prevents regrowth. Unlike simple cleaning, biocide penetrates the render surface and continues working long after application. It kills existing algae at the cellular level and creates a protective barrier that prevents new spores from establishing. The treatment bonds to the render and gradually releases active ingredients over 12 months to 3+ years, keeping your render cleaner for much longer than cleaning alone.
How long does biocide treatment last on render in Yorkshire?
In Yorkshire climate, professional biocide treatment typically lasts 12 months to 3+ years, and will depend on the position of the wall and exposure to natural elements. North-facing walls and heavily shaded areas may need retreatment sooner due to constant dampness. South-facing walls in full sun can stay protected for longer. The treatment doesn't suddenly stop working; it gradually becomes less effective over time. We recommend retreatment when you notice algae starting to return.
Is biocide treatment safe for my family, pets, and garden?
Yes, when applied by trained professionals. We use professional-grade biocides that are safe when used correctly. During application, we cover plants and keep pets indoors. The products are wet when applied but become inert once dry (usually 2-4 hours). After drying, treated surfaces are completely safe for children and pets. We use biodegradable formulations where possible and take extensive precautions to protect your garden and surrounding areas.
Can I apply biocide treatment myself or do I need a professional?
While DIY biocide products are available, professional application is much more effective. We use commercial-grade products that are stronger and longer-lasting than retail versions. More importantly, we know the correct dilution rates, application methods, and dwell times for different render types. Incorrect application can be ineffective or even damage render. We also have proper safety equipment and insurance. Professional treatment costs more initially but lasts much longer than DIY attempts.
Will biocide treatment change the colour or appearance of my render?
No, professional biocide treatment is invisible once dry. It doesn't change the colour, texture, or appearance of your render in any way. What you will notice is that your render stays cleaner and brighter for much longer. Some homeowners worry about colour change, but what they're actually seeing is the removal of algae revealing the original render colour. The biocide itself leaves no visible residue or discolouration.
