Moss And Algae Treatment in Winchester , Hampshire

Unlike standard jet washing that only removes surface debris, our professional approach focuses on the root cause of the problem. We use advanced, controlled biocidal solutions specifically formulated to kill lichen, moss, and algae spores deep within the pores of stone, concrete, and masonry. By targeting the spores, we prevent rapid regrowth and ensure your surfaces stay cleaner for much longer. For delicate areas such as roof tiles or painted facades, we utilise a gentle soft-wash method that achieves deep sanitisation without the risk of physical damage caused by high-pressure water.

Moss and algae are more than just an eyesore; they can be a genuine safety hazard and a cause of long-term structural damage. During damp Hampshire winters, these organic growths create incredibly slippery surfaces on walkways and patios, increasing the risk of falls. Furthermore, moss retains moisture, which can cause tiles to crack during frost cycles or lead to accelerated weathering of block paving. Choosing a professional treatment preserves your exterior surfaces, prevents costly repairs, and significantly boosts your home's kerb appeal.
