En suite stain that stayed damp between showers
The property
A 1970s detached house with a side extension, where a newer en suite sits above the lounge and its pipes run between the joists.
The problem
A brown patch on the lounge ceiling stayed damp even on days nobody showered. The silicone had been redone twice.
How we found it
Moisture readings stayed high whether or not the shower ran, which pointed to a pipe under pressure. Only the hot supply lost pressure on test, and thermal imaging with hot water running showed the spread.
The outcome
Reached through a small opening in the lounge ceiling at the mark, the joint was repaired on a separate quote, and the en suite tiles stayed untouched. The report went to the insurer.
