Black Spot Removal in Petersfield , Hampshire

Standard pressure washing is often insufficient for black spot removal because the lichen is a biological growth that creates a root system within the stone. Our expert team follows a precise, multi-stage restoration process. We begin by applying a specialist, biodegradable treatment designed to break down the lichen spores without causing damage to the surrounding environment. This is followed by a high-performance hot water pressure wash, which lifts the debris gently from the surface. This combination ensures that the stone is cleaned thoroughly while preserving its structural integrity, leaving you with a rejuvenated, clean finish that lasts much longer than traditional methods.

Opting for professional intervention rather than DIY store-bought chemicals is essential for protecting your property. Different types of stone require specific handling; sandstone and limestone are particularly sensitive to high-pressure water and acidic cleaners. Our technicians are fully trained in the chemistry of stone cleaning, ensuring we use the right balance of pressure and treatment for your unique surface. By hiring our specialists in Petersfield, you avoid the risks of etching, pitting, or discolouration that often occur when using incorrect equipment or aggressive chemicals on natural stone paving.
