    Took some vertical blinds down to decorate, there were issues with the beads around the windows and got a plasterer in to sort out. He did me a favour and neatened up the plaster around the window recess but in the process covered up the holes for the blind fixing. Trying to put a plug in for a new fixing and getting refusal at 20mm. Its plasterboard initially but then a lintel presumably. Its an 80's house. The old screws are 40mm so can't quite figure out how they went in and the way forward.
    Any ideas please?

    If it is a metal lintel / beam then a metal drill bit is required.

    If not, then an SDS drill is required.

    How do I know which one it is?

    Try drilling it with one or the other.
    If you try HSS (metal drill bit) first and it doesn't do much and comes out blunt, then you need SDS with masonry bit.

    If you try masonry bit first and it wont drill then it's probably steel.

    If your putting the blind back up in same place, is there anyway you can judge where the old lintels would have been drilled and re-use those?

    Thanks for the replies, its only a small temp blind so bodged it with a cut down plug this time.

    I reckon its a steel lintel and never had success drilling into steel but probably because my bits aren't up to it. Do SF do any that would be?

    Plenty mate, the gold Erbauer ones are surprisingly good, especially for the money

    Self drilling metal screws. I fitted 4 wood venetian blinds in 40mins.

    No pilot hole just mark where you want the bracket and drive the screw in it will go through everything and make irs own thread. Stronger than a plug for sure.

    Thank me later

    They're more commonly called baypole screws I should mention. Sfix do sell them but at likr 4.8mm thick, I've used them they work but will take longer to go through. I've got some 3.5mm I got off ebay they fly in

    That's interesting, they look like the ones that came out, although they had been plugged as well. Can they be used twice in a new hole or does the first fixing blunt them?

    Just make sure you get enough depth 50mm should do it. If your drill bit holder is magnetic you'll know when it's working as you'll get shards stick to the bit.

    Remember your drilling metal so keep a nice steady medium speed not too fast not to much pressure
