The job, explained
What patio cleaning & sealing involves
Patios and paths are where green algae and ground-in dirt show up fastest, especially after a damp London winter. We bring slabs, paving and natural stone back to their proper colour, clear out the joints, and can seal the surface to keep it cleaner for longer.
What's included
- Moss, algae and weed pre-treatment
- Deep clean across slabs, pointing and edges
- Joint re-sanding where needed
- Optional sealant to resist staining
- Care taken around borders and planting
- Full rinse and tidy-up

Good to know
Common questions.
Can you get rid of the green and black marks?
In most cases yes. The green is usually algae and the black is ingrained dirt or lichen, and both respond well to pre-treatment plus a proper clean. Very old staining can be lightened rather than fully removed, and we'll tell you honestly what to expect.
Is sealing worth it?
If you want the patio to stay cleaner and resist stains from food, drinks and weather, sealing is a good idea. It's optional and we quote it separately so you can decide.
