Why Choose Our Moss & Algae Treatment in Hedge End & Eastleigh?

How we restore your surfaces

Our cleaning process is tailored to the specific needs of each surface, ensuring optimal results without causing damage. We begin with a thorough inspection of the area to identify the type of growth and the substrate material, such as block paving, sandstone, or concrete. We then apply an appropriate biocide treatment to neutralise spores and soften the biological build-up. Once the treatment has taken effect, we use controlled pressure washing or soft washing techniques to clear away the debris. Finally, we apply a post-treatment to inhibit future regrowth, leaving your patio or driveway looking fresh and clean for much longer.

Why choose professional treatment for your property?

Using DIY methods often only removes the surface layer of moss or algae, meaning the spores remain behind to regrow almost immediately. Our professional biocide treatment penetrates deep into the pores of the stone or paving to kill the organism at its core, which is essential for effective lichen and black spot removal. Beyond the aesthetic benefits, regular professional cleaning prevents the long-term structural damage caused by organic growth, which can hold moisture and lead to cracks or loose pointing during the freezing winter months. Our service ensures your walkways are safe, non-slip, and aesthetically pleasing year-round.

Is chemical treatment safe for my garden and home?

Safety is the foundation of our work at Under Pressure Southern. We carry full public liability insurance and are trained in the careful application of professional-grade chemicals. We take great care to protect your surrounding garden plants, lawns, and pets during our cleaning process. Our treatments are formulated to be highly effective against biological growth while remaining safe for the local environment. We always adhere to strict guidelines regarding chemical usage and surface management, ensuring that your property is restored responsibly and securely.

FAQ

Frequently Asked Questions

Answers to common questions about our professional moss and algae treatment services in Hedge End, Eastleigh, and across Southampton.

Why do I have black spots on my patio that won't wash off?

+

Those black spots are actually a type of lichen that anchors itself deep into the pores of your stone. Standard pressure washing often fails to remove them because they are physically "rooted." We use a specialist black spot treatment that breaks the bond between the lichen and the stone, allowing us to wash them away safely without using excessive pressure that could damage your patio.

Is the moss treatment safe for my pets and garden?

+

Yes, we use HSE-approved biocides and cleaning agents. We take great care to pre-wet surrounding grass and plants to prevent any absorption and rinse everything down thoroughly. Once the treated surface is dry, it is perfectly safe for pets and children to walk on. We always discuss any specific concerns you have before we start the job.

How long will it take for the moss to grow back?

+

While we can't stop the UK weather, our biocide treatments keep surfaces clear for much longer than water alone. By killing the microscopic spores, we usually see surfaces stay clean for 12 to 24 months, depending on how much shade and rainfall the area gets. Many of our Hedge End customers opt for a quick annual "top-up" treatment to keep their driveways looking perfect year-round.

What is the difference between pressure washing and soft washing?

+

Pressure washing uses high-force water to knock dirt loose, which is great for hard concrete or stable block paving. Soft washing uses low pressure—similar to a garden hose—combined with specialized cleaning solutions to kill organic growth. We often use a combination of both to get the best result for your specific surface.
