The answer to 'how to maintain patio installation' is to regularly clean, inspect, and make minor repairs to keep your patio looking its best. This includes sweeping or power washing the surface, checking for cracks or uneven areas, and sealing or repairing any damage as needed.
For a paver or stone patio, use a stiff-bristle broom or leaf blower to remove dirt, leaves, and other debris at least once a month. Periodically use a patio cleaner or mild detergent and a scrub brush to remove any stains or built-up grime. Inspect the patio for cracks, settling, or loose pavers and address any issues promptly to prevent further damage.
