Hi

If a manufactured solid wood FD30 door has the top leading edge corner cutoff by the site team am I right to say that this invalidates the door as it is no longer as tested and that they cannot simply remove 25mm of the chamfered edge and replace this with hard wood then fill and repaint. Also the doors are Todd Doors who state that they dont need stickers or plugs on teir doors as they have a certificate that covers all doors.

From the manufacturer:

Trimming Note	In trimming any part of this door you will need to re-seal the exposed edges. In trimming the height the core may become exposed. Please contact a Door Expert about the appropriate finishes available for this door.
