Our Approach
The right method for every surface
Considered, precise and property-specific. We assess every surface individually, choose the correct method, and take the time to do it properly — not the fastest way, the right way.
We use the lowest pressure and the minimum amount of chemistry required to achieve the desired result. We would always rather build both gradually, only where needed, than start aggressively and risk compromising the surface.

A tailored approach
We assess before we clean
No two surfaces are the same, so the method is chosen to suit the surface in front of us. Before any cleaning begins, we assess your property and weigh up exactly what the surface needs — and what could harm it.
That assessment is what lets us clean effectively without scarring stone, cracking render or forcing water where it shouldn’t go.
- The surface type and how it weathers
- Its current condition and age
- Any existing damage or loose jointing
- Moss, algae, lichen, black spot and staining present
- Drainage and where run-off will go
- Nearby plants, lawns, glass and painted surfaces
- Whether pressure, soft wash or treatment is most appropriate

Expertise by material
A different method for every surface
The same surface treated the wrong way is the most common cause of lasting damage. Here’s how our method changes with the material.
Natural stone & limestone
Low-pressure cleaning and soft washing lift growth without scarring or opening the surface.
Slate & clay roofs
Chiltern EverGuard™ and gentle removal — never high pressure, which forces water under tiles.
Block paving & driveways
Controlled cleaning, weed and joint clearance, then re-sanding to stabilise the surface.
Render & cladding
Soft washing with the correct dwell time cleans delicate coatings without damage.
Porcelain & patios
Surface-appropriate cleaning plus black-spot (lichen) treatment at the source.
Brickwork
Targeted treatment for efflorescence and organic staining, matched to the brick.
What we don’t do
Just as important as what we do
The wrong cleaning method can cause permanent damage — which is exactly what our approach is built to avoid.
- Blast every surface with maximum pressure
- Use one method for all materials
- Ignore underlying damage or loose jointing
- Make unrealistic promises about results
- Recommend treatment unless it's genuinely appropriate

Cleaning, restoration & treatment

Exterior care is more than pressure washing. Depending on the surface and the problem, we draw on a full range of specialist methods — chosen to treat the cause, not just the appearance.
- Controlled, low-pressure cleaning
- Soft washing for delicate surfaces
- Manual moss removal
- Chiltern EverGuard™ treatment
- Mineral and black-spot stain treatment

- Weed and joint clearance with re-sanding
