Aircraft door seals, especially door seals for aircraft cargo doors, include individual door seal sections joined together by a lap joint assembly. The door seal sections may have abutted ends establishing a seal junction, and a lap joint junction seal assembly to sealingly join the abutted ends of the door seal sections, wherein the lap joint junction seal assembly includes (i) a lap joint member having a lap joint base and a lap joint shelf extending from the lap joint base and sealingly engaged with a lower surface of the door seal sections over the seal junction, and (ii) an interior support spigot inserted within the interior space of each of the door seal sections at the abutted ends thereof. Each of the door seal sections may be a hollow profiled door seal defining the interior space and formed of an elastomeric sealing material.
