A cobbled driveway gives a home real character, but all those joints and textured stones are a magnet for dirt. When a homeowner in Eltham called us, their granite sett driveway had faded under moss, weeds, and years of ingrained grime. This was a perfect job for professional cobblestone driveway cleaning, bringing the natural stone back to life without harming the setts or washing out the joints.
Here is how we restored this characterful driveway, and why the right approach made all the difference.
The Problem: Character Hidden Under Grime
Granite setts, often called cobbles, are wonderfully hard-wearing. That is exactly why they have been used on driveways and streets for generations. However, their charm comes with a catch.
Every sett is surrounded by a joint, and every joint is a place for dirt to settle. Over the years, this driveway had collected:
- Moss and algae, thriving in the damp, shaded joints
- Weeds, taking root in the gaps between the stones
- Silt, leaves, and general grime, dulling the surface and darkening the setts
The result was a driveway that had lost its colour and, in places, become slippery underfoot. The character was still there, but it was buried under years of build-up.
Cobbled driveways like this are a familiar sight around Eltham, where many period and character homes feature traditional granite setts. They look wonderful when clean, but they do need the right care to stay that way.

Why Cobblestone Driveway Cleaning Needs the Right Approach
Granite is a tough stone, so it can take a proper clean. The skill lies in cleaning the setts evenly while protecting the joints between them.
A careless approach causes two common problems. First, cleaning with a narrow lance leaves a stripy, patchy finish, because it is almost impossible to keep the spread even by hand. Second, too much force in the wrong place can wash out the jointing sand and leave the setts loose.
So good cobblestone driveway cleaning is about control as much as power. We match the method to the surface, clean evenly, and protect the structure of the driveway as we go.
Our Cleaning Process, Step by Step
We worked through the job in clear stages to get a consistent, lasting result.
- Clear and prepare. First we removed loose leaves, debris, and surface weeds from across the driveway.
- Treat the growth. Where needed, a suitable treatment tackled the moss and weeds at the root, not just on the surface.
- Rotary pressure clean. Using a flat rotary cleaning head rather than a narrow lance, we cleaned the setts evenly across the whole area. This lifts the grime from the stone and the joints without the tell-tale stripes.
- Rinse through. We flushed away the loosened dirt and silt, leaving the setts clean and the joints clear.
- Final checks. We inspected the driveway and re-treated any stubborn patches for an even finish throughout.
A flat rotary head is the secret to a professional result on setts. It keeps the pressure consistent, so the whole driveway comes up evenly rather than in patches.

The Result: A Driveway Restored
The difference was dramatic. As the rotary head passed over the setts, the dull grey-brown surface gave way to warm, clean granite. The moss was gone, the weeds were cleared, and the joints were clean and tidy.
For the homeowner, a tired driveway had become a smart, welcoming entrance once more. The character of the original setts was finally on show again, and the slippery patches were a thing of the past.
Best of all, the clean reached deep into the joints, not just the surface of the setts. That even, thorough finish is exactly what a cobbled driveway needs, and it is very hard to achieve without the right equipment and technique.
Why Professional Cobblestone Driveway Cleaning Is Worth It
It is tempting to hire a pressure washer and tackle a cobbled drive yourself. Sadly, that often leads to a patchy finish, loose setts, and weeds that return within weeks.
Professional cobblestone driveway cleaning brings clear advantages:
- An even finish. A rotary cleaning head treats the whole surface consistently, with no stripes.
- Protected joints. The right technique cleans the gaps without washing out the jointing or loosening the setts.
- Longer-lasting results. Treating weeds and moss at the root slows their return, so the driveway stays cleaner for longer.
- Safety restored. Removing slippery moss gives you a safe, grippy surface again.
For a characterful driveway, that expertise protects both the look and the structure of the stone.
Keeping Your Cobbled Driveway Clean
Once the setts are clean, a little care keeps them looking their best. For cobbled and sett driveways, we usually suggest:
- Clearing leaves regularly, since they trap moisture and feed moss
- Dealing with weeds early, before they take hold in the joints
- Topping up the jointing sand if it works loose over time
- Booking a periodic professional clean, to lift grime before it becomes ingrained
These simple steps protect the character and safety of your driveway for years to come.
