Patio Cleaning in Bradwell

Indian sandstone became one of the most popular patio stones in English gardens in recent decades, and plenty of Bradwell homes have it. It looks warm and natural when laid, but after a few years many owners notice dark speckles spreading across the slabs. These black spots are a common reason people start looking for patio cleaning services.

Black spot is not dirt. It is a type of lichen that roots into the surface of the stone, so it does not simply wash off. Many people try a jet wash and find the spots barely change, while the stone around them gets roughened. Repeating that every year can wear the slabs down and make them grip dirt even faster.

The approach that works is slower. We apply a treatment suited to natural stone and leave it on long enough to work into the lichen. Over the following days and weeks, the spots usually fade further as weather does the rest. A rinse at a sensible pressure then removes loosened growth without opening up the stone.

Green algae and moss are a separate issue, and Bradwell gardens with fences and hedges on the south side often see plenty of both on the shaded part of the patio. These do respond to washing, combined with a treatment to slow their return.

If your patio is concrete or porcelain rather than sandstone, black spot is much less of a problem. Concrete takes a firmer clean, while porcelain needs a light touch and the right cleaner. Either way, we look at what is there before suggesting a method. Searching for how to clean Indian sandstone will turn up a lot of conflicting advice, and much of it is the cause of damaged slabs.

Bleach is one of the most common home remedies people try, and it is worth a word of caution. It can lighten sandstone unevenly, harm the plants beside the patio and run into drains. If you have already tried it, mention it at the visit, because it can affect which treatment we choose and how we test the stone first.

It also helps to know what a cleaned sandstone patio should look like. Natural stone varies from slab to slab, with some pieces darker or more veined than others. After cleaning, those natural differences become clearer, which is a sign the stone is clean rather than a fault. Patchy colour from over-washing is different, and that is what we work to avoid.
