Vinyl siding is one of the most popular exterior cladding materials for homes across the USA and parts of the UK. Homeowners choose it because it is durable, affordable, weather-resistant, and available in a wide variety of colours and finishes. However, like any exterior surface, vinyl siding is constantly exposed to rain, dust, pollen, mould, mildew, algae, bird droppings, and environmental pollution. Over time, these contaminants can dull the appearance of your home and reduce its curb appeal.
