Hello Folks,
I've searched the Forums for "window installed without cavity closer" and read some of the results - unf. they don't address my problem.
Our kitchen UPVC window has a loose UPVC windowsill with mould smell coming from below. Took it off to reveal the sight in the photos - I have stuffed the cavity wall insulation back down the gap and moved the heap of random things which were supporting/fixing the windowsill to the middle for your delectation.
I've seen videos of cavity closers being used to 'seal' the gap between the walls before windows are installed. Am thinking to install one then reinstall the sill (using 'Low modulus neutral cure silicone' as advised elsewhere in the forum) BUT the inner brick wall is about an inch below the outer - How can I get them to the same level?
Should I use a suitable wooden 'filler' screwed/siliconed to the bricks and aligned with the internal wall (plasterboard seems straighter than the wall tbh!) before fitting the closer, or is there a better solution?
I don't intend to remove the window so would need to cut the closer to suit around the plastic packers which are supporting the window. Also noticed that the sealant below the window is allowing light through in places so needs replacing from outside (reachable, not a problem).
Hope I've explained enough to elicit a comprehensive and helpful reply!
Many thanks in advance.
EDIT: Since posting I found this thread which seems to have a similar problem:
Any advance/advice regarding this is appreciated
