“The ceiling’s bubbling” — leak from an upstairs bathroom
This one was just off Crofton Lane. They’d noticed a small mark for a week, then it suddenly went soft after a shower. The easy (lazy) approach is to replace the bit of pipe you can see and leave. I traced it back to a tired compression joint behind the bath panel that had been nudged during a previous “quick fix”.
We isolated, drained, replaced the joint properly, then I stayed long enough to run the shower again and actually watch it. It’s not exciting, but it stops that horrible “is it still leaking?” feeling.
