One of my internal doors slowly swings fully open unless it's latched

something to do with how it's hung, but I can't find any obvious
problems. It's a solid hardwood door (so pretty heavy) hung on two
brass hinges.

A spirit level shows that the door frame on the hinge side is
vertical, and the hinge side of the door is vertical as well. A plumb
bob made from a nut&bolt on a piece of string shows that the two
hinges are in line vertically.

Any ideas on what could be causing this?


Either a bowed door or wind.

It's not wind, as it happens in still air.

But a check with a straight edge shows that the door is bowed
slightly, and the others that don't swing open aren't.Â* So I think you
may have found the cause.Â* Thanks.


If the door is bowed and currently sitting on 2 hinges, you could add
a third hinge in the middle which may reduce or eliminate the effect.

Enlighten me. I do not fit doors.

Who is going to fit your GF's new kitchen door ?.

Serious question, if the door was bowed the other way would it self close?

Or does this depend if the bow is closer to one hinge than the other?

use a sledge hammer as a door stopper :-)
