Help, I am COLD! My eleven year old, three-lock composition front door leaks the North wind straight into my front room where I sit. I think the draught excluding felt strip in the frame is worn, but also recently I had problems with locking the door, and the window/door repair company came out, tried to adjust it, said it was warped and could not be adjusted further and that I need a new door. I can't afford a new door!! They managed to get it to lock again, but now I am wondering if a) the draught excluder strip can be replaced, and by me, and b) will doing that affect the door itself so I won't be able to lock it again? A dreadful dilemma for a lady of a "certain age" on her own, with no one to call on for help. Any advice from you clever guys out there?
