Indian sandstone is a popular choice for patios in Upton upon Severn thanks to its natural texture and colour variation, but like any porous stone it does need a bit of regular care to stay looking good. The riverside town's damp winters and shaded gardens can encourage algae and moss if the paving is left untouched. A little routine maintenance goes a long way, and it's something SPR Paving happily advises customers on after installation.
Routine cleaning that actually works
Regular sweeping to remove leaves, dirt and organic debris is the single most useful habit, because that debris is what feeds algae and moss growth. A stiff outdoor brush and a bucket of warm water with a mild detergent will handle most everyday grime. For more established green staining, a dedicated patio cleaner suited to natural stone works better than bleach or harsh acids, which can affect the stone's colour and the pointing between the slabs over time.
A pressure washer can be used but needs a gentle setting and a fan nozzle held at a reasonable distance — too close or too powerful, and you risk stripping the surface texture or blasting out jointing sand and mortar. It's worth doing this once or twice a year rather than leaving it until the patio looks badly stained, since built-up grime is always harder to shift.
Dealing with damp, shaded corners
Gardens near the river or under tree cover tend to hold moisture longer, which is exactly the environment moss and algae like. Improving drainage where possible, trimming back overhanging branches to let more light and air reach the paving, and treating problem areas with a proprietary moss killer designed for stone will keep things under control. Sealing the sandstone after a thorough clean can also help — it doesn't stop dirt landing on the surface, but it makes future cleaning noticeably easier and can enhance the stone's natural colour.
