Hello all,

Recently had some double French doors installed and I’ve noticed in the corner where the beads meet there is a gap. And, through this gap is coming a very strong draught - I’ve tried sealing the vents to see whether or not the draught was travelling through the door from the top to the bottom (very unlikely I know).

Frame outside looks like it’s sealed properly and all the joints on the external fascia also look solid. What could be causing this?

How recently? That's rubbish manufacturing get them back to sort it out.
 
10 months ago - however, found out that despite been FENSA registered and offering a Home Pro insurance back guarantee, the doors haven’t been registered. They’re Crayton Branded, which I thought were good.
 
Never heard of Crayton tbh - not a profile manufacturer to my knowledge so can't comment If they are good or not. What may have happened is that the beads are in the wrong place. Either get the installer back or if you are diy confident , swap the left and right bead over and see if the joint is any better.
 
Just to add , is it actually a draft? , because in theory the glass unit should still be pushed tight against the external rubber seal creating an airtight seal on the outer edge
 
Definetly coming in that gap in the bead? Or elsewhere round the door frame
 
If there's a draught definitely blowing out of that mitre and that is a shocking mitre joint then it could be blowing through the frame drainage then into the door drainage glazing channel and out or in through the bead mitre, as a test open the door and tape up the drainage slots under the door to see if that helps
 
Definitely coming through the mitre on the beats. I’ll tap over the drainage holes and see if it makes a difference
