Moss And Algae Treatment in New Alresford , Hampshire

Unlike aggressive high-pressure cleaning that can sometimes damage delicate stonework, our soft wash approach is designed for longevity and surface protection. We apply advanced, environmentally responsible biocidal solutions that penetrate deep into the pores of your masonry or roof tiles. This process does not just clear away surface-level green growth; it targets the spores at the root to prevent rapid regrowth. By neutralising the organisms, we provide a deep clean that keeps your exterior surfaces looking fresh for much longer.

Damp moss and algae on walkways, patios, and car parks are notorious for becoming slippery, especially during the wetter months in Hampshire. Regular treatment is a vital part of property maintenance that reduces the risk of accidents for family members, visitors, or customers. Beyond safety, consistent removal prevents the structural damage that moss can cause as it expands within cracks and under tiles. Choosing our expert service ensures your property is treated with the care and precision required to maintain its value and structural integrity.

We take our responsibility to your property and the environment seriously. Every treatment we perform is fully insured and strictly follows Health and Safety regulations, including full COSHH compliance for all chemical applications. We ensure that your plants and garden areas are protected during the cleaning process, selecting the appropriate biocidal strength for your specific surface type. By choosing Under Pressure Southern, you are opting for a reliable local team that prioritises safety and regulatory excellence in every job.
