Hi, some advice would be appreciated!
We've had an extension built and wish to fit a venetian blind (already made to measure and delivered) into the window recess.
Unfortunately there is a steel lintel right above the plasterboard which prevents me top mounting the blind in the way I've done before, using plasterboard plugs. As the windows are upvc I'm really not sure about making holes in the window frame, how to do it or whether it would work. The builder has advised that the window company won't invalidate the guarantee if I do this.
This must be a reasonably common problem - can someone advise? Is there another solution using some kind of adhesive? ("No more nails?") And if the answer is to make holes in the plastic window frame, any advice on how to do it so it won't fall down?
Thanks.
