unwarping a door?

[George]

The front entrance to our house has a small vestibule off the porch. The entrance has double outer doors, which doors have large glass inserts. So, just stiles, top & bottom rails, and glass. Because they're on the porch, the doors are not directly exposed to weather, but they are 'outside'.

The problem is, one of these doors appears to be warped: the center top is pulled in relative to the stop moulding, and likewise relative to its mating door, which it should close and latch with. AFAICT, it is the door itself, not the frame, which is warped.

I'd appreciate any thoughts/experience with correcting a warped door.

Thanks

About the only way I know is cut a kerf, straighten, fill remaining kerf with glued in dutchman. That works for cabinet door, should be possible with bigger doors but the glass could be a problem. Can't be much of a warp if the glass didn't break. OTOH, it may well be a temporary effect due to the outside being exposed to more humidity.

It's from the heat on the outside. You need heat on the inside to unwarp it. Have an extreme heat source from the inside, you may want to remove all your belongings before you start a fire inside.

Your odds of success are not that good because the large glass areas don't contribute much rigidity. Best consider having a new door constructed at a good carpenter/woodworking shop. Well seasoned lumber could make the big difference in getting a warp resistant replacement door. Trying to get the current door flattened by clamping to some other flat structure is dicey and likely rather time consuming. Your neighbors would wonder why you had the front entry boarded up while this was ongoing.

I agree, cutting and gluing kerfs sounds like the best way to cure it.
