I noticed some staining in & around area below the radiator in the extension over the past week or two.
Extension is nearly 2 years old now & this has just begun to show through the heavy lino flooring.
I've monitored it closely and it seems to be a slow drip from piping behind the wall feeding said radiator (when I isolate the rad, dripping noise stops).
Q: does the builder retain any liability for this after nearly 2 years?
No work has been carried out since extension was built.
Thanks in advance,
Bren
