Hump through the doorway
We're installing a solid woven bamboo floor in the kitchen/dining room, adjoining hallways, and living room of our 1972 house on a subfloor. We removed engineered wood floors from the kitchen/dining area and hallways. The living room has had carpet for the last 35 years.
The problem is that as we came to the open doorway between the dining room and the living room, we realized there is a hump in the floor as you pass from one room to the other. Checking the hall floor on the same line, there is also a hump there.
Dining room transition to living room (that's a piece of the bamboo):
Hallway along the same line:
The gap you see is 3/8" at most.
This hallway had wood flooring until last week and we never noticed this hump before. Of course, the guy who installed that floor used monster staples and bamboo requires delicate 1-1/4" brad nails.
We're wondering if we scrape away the vinyl, maybe 8" on either side of the hump, and even plane away a bit of the underlying plywood, if we could reduce the the hump sufficiently. Is this even a good idea? Is there a better method?
