I am preparing to do some reparing to the plasterwork of my daughter's house. She has stripped off the wallpaper and this has pulled off some of the worst plaster. It has exposed a very rusty pipe near to the fireplace.
Can anyone suggest how I can check (or have it checked) to ensure it isn't still connected to the gas supply. Tracing the pipe would be tricky as it would mean lifting floor to find it.
Suggestions please.
