My contractor just hung our fancy dancy un-painted solid wood door slabs in my 100 year old house with solid hardwood floors throughout. There is an approximately 1.5" gap at the bottom of the doors. I think it is too big and think a 1/4"-1/2" gap would accommodate any unevenness in our floors and allow us to use area rugs. Is there a standard size for the gap at the bottom of the door? If it is in fact too big, how do we fix it?
This was part of a major renovation that involved replacing all the trim and repairing damaged plaster. The areas around the doors were stripped down to the studs and headers, but the hardwood floors were left in place. There is no sort of threshold on the floor between the rooms as the hardwood floors run throughout the house.
There us also one other possibility. If you have HVAC and there is a grill in the room and there is no return in the same room, when the central heating/ cooling system is turned on it would create a high pressure in those rooms. Therefore sometimes a door cut higher is a viable solution to equalize the pressure. Removing the doors and cutting down the jambs IS NOT a viable alternative because the tops of doors and windows should plain out same height.
I personally would do some type of detail on the bottom if the door if it was not necessary by design to equalize pressure. Get creative and there is a tremendous opportunity to do something quite unique. Such as a motion activated KED light strip as one example.
