I have a refurbished property with new build walls & replacement aluminium double glazing which I have problems with. Nearly all windows have new brickwork around them & some are new (replacing a garage) I think that the builders/installers have not put cavity closers in or sealed the cavities & I'm having this checked.
I've read Building Regs Part L (?) and cannot find a simple answer! Can anyone tell me whether this should have been covered by BR as the rest of the refurbishment was?
