Professional Moss and Algae Treatment for Horndean Homes

Under Pressure Southern provides expert moss and algae treatment services across Horndean and the surrounding Hampshire area. We understand that our local climate often leads to the build-up of unsightly moss, lichen, and red or green algae on exterior surfaces. These organic growths are more than just a visual nuisance; they can make driveways, patios, and pathways dangerously slippery while causing long-term damage to stone and masonry. Our dedicated team uses advanced, professional-grade biocidal treatments to eliminate these spores at the root, ensuring your surfaces stay cleaner for longer.

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

Why Professional Biocidal Treatment Beats DIY Methods

Many property owners attempt to remove moss or black spots using basic household jet washers, but this often fails to address the root system of the growth. Without the correct biocidal wash, spores remain deep within the pores of the stone or block paving, leading to rapid regrowth within weeks. Our process involves a thorough assessment of your surface type followed by the application of specially formulated solutions that break down lichen and algae safely. By choosing our professional restoration service in Horndean, you avoid the risks of using overly aggressive pressure that can etch or damage your property substrates.

Comprehensive Care for Your Exterior Surfaces

Our service covers a wide variety of hard surfaces, including block paving, natural stone, concrete, and brickwork. Whether you are dealing with stubborn black spot on your patio or a slippery film of green algae on your driveway, we have the expertise to restore it. We take a methodical approach, beginning with a pre-treatment application to soften organic matter, followed by controlled low-to-medium pressure washing to lift debris without causing surface erosion. The final stage involves a protective treatment to help inhibit future regrowth, keeping your property looking its best through all seasons.

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.
