Do you have any recommendations for someone who could install blackout blinds?
To be clear, what we are after is something like the Velux blinds:
I have only seen them in lofts, but I see no reason why they couldn't be installed in any room.
These do the job because they tend to leave little to no gap and therefore to block out almost all the light. Of course exact measurements are needed.
To be clear, we are not interested in those you can buy from Argos, Ikea, John Lewis, etc, like these below, because, from experience, they tend to leave quite a big gap through which too much light finds it way into the room, defying the whole point.
In the past we used these guys: http://cornerstaraluminium.com/
who did a good job, but I was wondering if there is any other recommendation for someone who is maybe more local.
