I live in the UK and I am installing some shelves in the cupboard under the stairs and I'm wondering if the material I'm drilling into is dangerous. It is the Party Wall between two houses.

This could be paint, textured wallpaper, plaster, render and blockwork. But it's hard to see from the photo what that brown stuff is - is it hard like render/scratch coat or is it softer?

Depending on the age of the property, any of these could contain asbestos - the most likely culprits being the wallpaper and/or the render/coating (particularly if it's crumbly/fibrous? hard to tell from the photo).

The only way to know for sure is to (carefully, using appropriate precautions) take a sample and send it to a lab for testing. Asbestos testing services for consumers are available at relatively modest cost - search online for asbestos sampling kits.

Another more expensive alternative is to pay for an asbestos survey: a surveyor will come and inspect the whole house and take samples of any suspect materials. If you're planning major work in the future this may be worth doing.

You need to make your own risk/cost decisions. Personally, I would just go ahead if the brown stuff looks like render (i.e. if it's hard/sandy) - but always wear a mask and keep dust down regardless (any kind of dust in the lungs is unhealthy!) If it looks softer or fibrous I would have it tested for sure.

  • Hi aucuparia, it's more grey than brown and it is like cement/concrete with stones or something and crumbly but not fibrous. Sounds like its probably not? But wallpaper might be? – Adam Griffith Apr 8 at 12:44
  • Literally anything pre-1999 could have asbestos in it. It was incredibly useful and cheap so it was used all over the place. So - the answer is always "if in doubt get it tested". It sounds like some kind of render to me, so I would say unlikely to be a big asbestos risk. Hang around for a second opinon though. Wallpaper: more risk if pre-1980. – aucuparia Apr 8 at 13:12
  • Ok thanks aucuparia! I will see if anyone else answers before I proceed. – Adam Griffith Apr 8 at 14:41
