How high should doors be above carpet?

As a general rule. Holding the jambs up 1/2″ -3/4″ where there is carpet is our rule in new construction. Door slabs are usally 1″ up from bottom of jamb on prehungs. So with 1/2″ pad and up to 1/2″ carpet, that’ll leave a 3/4″ gap, below the door.

If you have a large gap beneath the door, use a wrap-around door sweep. They have long adjustable sides that can be moved up and down along the width of the door. When the bottom of the sweep fills in the door gap, drill pilot holes through the sides and screw it down. Put in a door threshold.

Does carpet go under door casing?

2 Answers. I always hold casing to the same height as the base trim (3/8″ or 7/16″ is enough–1/2″ risks showing a gap with thinner carpets). However, if the casing is already installed, don’t bother making cuts now. Carpet layers can easily deal with that situation by tucking against it.
