Moss And Algae Treatment in Eastleigh , Hampshire

Unlike basic jet washing, which often only clears the surface, our specialist treatment targets the root cause. We apply professional-grade, biodegradable biocides that penetrate deep into porous surfaces to kill spores of moss, algae, and lichen. This prevents rapid regrowth and ensures a longer-lasting clean for your block paving, sandstone, or concrete. Depending on the level of buildup, we follow this with a precision hot or cold pressure wash, carefully managing water pressure to ensure your surfaces are deep-cleaned without suffering any structural damage or etching.

Beyond simple aesthetics, letting moss and algae take over your exterior surfaces can lead to long-term damage. Moss can retain moisture, causing mortar joints to fail and leading to cracks during winter freeze-thaw cycles. Meanwhile, the slippery film created by algae on paths and drives poses a significant slip hazard to residents and visitors. By investing in regular, professional treatment, you are effectively protecting your investment, improving your home's kerb appeal, and ensuring that walkways remain safe throughout the wetter months in Eastleigh.
