I was on my way to work this morning. I got a phone call from my mum. She mentioned that she had noticed multiple water stains on the ceiling in the dining room.
I headed over. There were indeed multiple water stains on the ceiling.
I didn't want to go upstairs and start ripping up flooring.
There was a long water stain (on the ceiling) under a upvc window that I discovered had a recently had a blocked drainage hole. By all accounts, the hole was cleared a few weeks ago but the water was previously running on to the interior window sill.
The ceiling stain then ran in other directions, primarily following a series of joists.
I decided to use an oscillating saw to cut holes in the ceiling.
The ceiling is twin skinned plasterboard.
After cutting through the lower level of plasterboard (in each of the holes that I made). I could see (large) beads of water in between the two layers of plasterboard. the original plasterboard had been painted before the ceiling was overboarded. The dust above the upper layer of plasterboard however was dry.
I had initially thought that the stains might be the result of drainage or central heating pipes. They would however make the top of the plasterboard wet.
Assuming that it was related to the double glazed drainage hole, and that the water ran down the interior wall to the upper level of plasterboard, realistically how long could the water be trapped there?
