We are replacing interior, luan doors with raised panel doors. We brought the old doors to the store and the fellow measured the old ones and matched the new doors to the same size. He also notched out a small section where the hinges are recessed. We had to chisel out slightly more wood (1/16”) to get the hinge to mount flush. The old doors were stained; the new ones came with a coat of primer and we added one coat of semi gloss paint. We purchased new hinges. The hinges appear identical to the old ones only the news ones are nickel coated. The problem is that after we hang the door it seems to almost fit perfectly except it won’t stay completely shut; it tends to pop open an inch or so. The thicknesses of the doors match exactly 1 3/8″.
