Patio Cleaning and Resealing

Restoring a stone patio in Sussex

We recently visited a beautiful property in the heart of Sussex to assist a homeowner whose large stone patio had lost its lustre over several seasons of neglect. The customer reached out to us because the surface had become a significant slip hazard, covered in a thick layer of green algae and stubborn black spot lichen that made the outdoor space unusable for the family. As a family-run firm with over twenty years of experience, we understand that a patio is an extension of the home, so we were keen to restore it using the professional methods we have honed over two decades.

Assessing the stone before we started

Upon arrival, we assessed the condition of the stone and the integrity of the pointing to ensure we selected the most appropriate pressure settings. The algae had taken a firm hold across the full width of the patio, and the black spot lichen had worked its way into the texture of the stone. We checked a few areas by hand to gauge how deeply the growth had set in and to confirm the pointing was sound enough to withstand the cleaning process without being dislodged.

Cleaning methods and equipment used

We began the process by applying a professional-grade cleaning solution designed to break down organic growth at the root. We then utilised our industrial petrol-powered pressure washers, fitted with specialised flat-surface cleaners, to achieve a uniform finish without the zebra-striping often caused by domestic equipment. By carefully controlling the water pressure, we were able to lift years of ingrained dirt and grime while protecting the delicate surface of the stone. A thorough rinse followed to clear away all loosened debris, leaving the area completely clean and ready for the next stage.

Sealing the patio for long-term protection

Once the patio was fully dry, we returned to apply a high-quality breathable sealer. This stage is crucial as it creates a protective barrier against future moisture ingress and organic staining, ensuring the vibrant colours of the stone remain visible for much longer. We worked methodically across the whole area to achieve an even coating, taking care around the edges where the patio met the house and garden borders.

The finished result and maintenance advice

The end result was a bright, clean, and safe environment that looked as good as the day it was first laid. To keep the area looking its best, we advised the customer to regularly sweep away fallen leaves and avoid using harsh household bleach, which can damage the stone over time. Instead, a simple seasonal wash with soapy water is usually enough to maintain the finish.
