Patio cleaning and sealing in Ipswich to lift moss, algae and black spot off tired paving. Cleaning is only half of it. Re sanding the joints and sealing the surface slows down how quickly the green comes back.
A pressure washer set too high strips the surface off soft sandstone and blasts the jointing out of block paving. We match the pressure and the nozzle to the paving, and use a treatment for algae and black spot rather than relying on force alone.
More Information
Once a patio has been cleaned, the joints are usually empty. Left open they let weeds in and let blocks shift. Block paving is re sanded and vibrated in. Slabbed patios are repointed where the mortar has failed. This is what keeps the surface tight.
A sealer soaks into the surface and makes it harder for water, dirt and algae to get a hold, so the patio stays cleaner for longer and washes down more easily. It also brings out the colour in natural stone. Most sealers need redoing every few years.
Cleaning and sealing is often the cheapest way to change how a garden looks, and Gardenwise Landscaping and Gardening takes on plenty of it around Ipswich alongside new paving. After 25 years we can usually tell whether a patio needs cleaning or replacing, and we will say so. Free quotations.

Most patios in Ipswich benefit from a clean once a year, usually in spring after a winter of moss and algae. Sealing lasts longer, generally three to five years depending on the product used and how much traffic the patio takes.
Black spot is a lichen that bonds tightly to the surface of the stone, and it will not come off with a pressure washer alone. It needs a specific treatment left to work, sometimes more than once. Sealing afterwards makes it much slower to return.
Sealing suits porous surfaces such as sandstone, limestone and concrete paving, where it reduces staining and slows down algae. Porcelain does not need it. The patio has to be clean and fully dry first, or the sealer traps whatever is underneath it.
