Recurring damp is not always a plumbing leak
When the mark appears, where it sits and whether it follows rainfall or water use all help narrow the cause before repair work begins

What Jersey properties teach us
Older homes, extensions and mixed heating systems rarely behave like standard examples We start with the building, how it is used and what the owner wants to improve
A replacement boiler should not be sized by habit
Room-by-room heat loss, emitter output and the condition of the existing system give a better basis for design than assumptions alone
Why heat calculations matter →First-fix decisions determine the final finish
Accurate setting out, suitable pipe routes and coordination with the wider project make bathrooms easier to complete cleanly and maintain
