A patio clean should leave you with stone that looks close to the day it was laid - even colour, no black spot lichen, joints free of moss, and no green slick across the edges where it stays damp. That's the standard we work to on every job in Crook.
The idea that a pressure washer alone will sort a lichen-covered patio is one of the most common misunderstandings we come across in Crook. Blasting black spot lichen off the surface just spreads live spores across the rest of the stone and into the joints - it looks clean for a few weeks, then comes back worse.
It's not just about how it looks on the day either. Treating lichen properly rather than just pressure washing it means the result actually lasts, and a sensible sealing conversation afterwards protects the finish through the next few wet seasons.
Fully Insured, Every Job

- Fully insured
- Full insurance cover on every job, residential or commercial.

- Spill management trained
- We control run-off and chemical use so treatments stay where they're meant to, away from plants, ponds and drains.
Limestone
- Limestone is calcium-based, so it can react badly to strongly acidic cleaning products - we're careful about what we use on it. It's also porous like sandstone, so black spot lichen treatment and adequate dwell time matter here too.
- We keep pressure low on limestone and let the biocide do the work of lifting growth, rather than relying on force that can etch or dull the surface.
Side Passages, Steps and Tight Access
Not every patio is reachable in a straight line from the road - side passages, steps down to a sunken garden, or a shared access path all change how a job's approached. We ask about this at quoting stage so there are no surprises on the day.
Longer hose runs or hand-carrying equipment through a tight passage can add a little time, which we'll factor honestly into the price rather than springing it on you afterwards.
Patio Cleaning in Crook — common questions
If your patio's looking patchy, dark or slippery, it's very likely lichen or algae rather than anything more serious, and it's fixable. We treat it properly, clean it thoroughly, and tell you honestly if anything else - like re-pointing - needs attention.
Do It Once, Do It Properly
A biocide treatment followed by the right clean for your material costs a bit more upfront than a straight pressure wash, but it lasts years longer. We'll explain exactly what your patio needs and why.
