Why Hinuera stone needs specialist care
Hinuera stone is a premium, natural material that gives homes and buildings a unique, elegant finish. But it’s also soft and porous, which means it requires expert cleaning methods. Unfortunately, most general house washing companies simply don’t have the training or tools to treat it safely.
Many homeowners assume standard exterior cleaning is suitable for Hinuera stone—and that’s where the trouble starts.
The risks of using general house washers to clean your Hinuera stone home
Water blasting Hinuera causes irreversible damage
Most house washing services rely on high-pressure water blasting. On Hinuera stone, this leads to:
-
Permanent texture damage
-
Surface erosion
-
Etching and scarring
-
Loss of natural protective layers
-
Waterblasting drives black mould deeper into the pores of the stone.
-
Once the stone is damaged, it cannot be repaired.
Incorrect chemicals can stain or burn Hinuera stone
Many off-the-shelf cleaners and standard house washing products react badly with Hinuera. This can cause:
-
Yellowing or discolouration
-
Chemical burns
-
Patchy, uneven finishes
-
Some cleaning companies mistakenly use bleach or chlorine products, leading to white stains on the stone.
No proper advice on long-term maintenance
Most builders and cleaning companies don’t explain how to maintain Hinuera stone. For homeowners, this often leads to mould, lichen, staining, and unnecessary long-term costs.

The importance of sealing Hinuera stone
Cleaning is only the first step. Sealing your Hinuera stone is essential for long-term protection.
-
Creates a moisture barrier that prevents water from sitting in the pores and reduces mould growth.
-
Prevents mould, moss, and lichen growth
-
Stops staining and moisture absorption
-
Retains natural colour
-
Extends the stone’s lifespan — this helps prevent deterioration of stonework when the full maintenance programme is followed.
-
Unsealed Hinuera becomes increasingly difficult to clean each year. Sealing protects your home and keeps it looking new.

Common questions
How do I clean Hinuera stone?
Hinuera is a very complex stone and general house washing companies who clean multiple surfaces (e.g. roofs, fences, weather boards, bricks and concrete) run into trouble when asked to clean Hinuera, because of its natural and unique properties. Unfortunately they often realise they have damaged the stone after it's too late. Avoid DIY methods and general house washing services. Professional & specialist treatment is the safest and most effective approach.
Can I waterblast Hinuera stone?
No—water blasting causes irreversible damage. It removes the surface layer, leaving the stone rough, scarred, and vulnerable to moisture.
Why is specialist Hinuera cleaning more expensive?
Because the stone requires expert knowledge, specific products, and trained professionals. Cheaper general cleaning often leads to costly repairs later. Specialist care protects adjoining materials such as windows and aluminium finishes, helping you avoid even more damage.
Do I need to seal my Hinuera stone?
Yes. Sealing is essential for long-term durability and appearance.
