Full of Bank Holiday spirit I decided to replace the crappy old Swish curtain rail above my patio dorrs with a nice new curtain pole - All was going swimmingly until drilling the holes for the mountings I came slap bang up against the lintel about 3/4's of an inch below the plaster. Foolishly I'd assumed I'd be able to drill into this as the previous owner had for the swish rail, but it's made of sterner stuff than my drill bits.
What's my best course of action now please ? Refitting the swish rail isn't an option as it was on it's last legs, and the missus has started tutting already.
