Removing glued Engineered hardwood from 3/4 subfloor

Afternoon,
I had a toilet utility line break and flood the first floor of our open floor plan house. The service company came and dried out the floor and in the process ripped up a large portion of the hardwood floor which gouged the subfloor significantly. The contractor wants to cut out the subfloor to remove the hardwood floor and replace it. Is this the best way to do this?? I have concerns with cutting out almost all of the subfloor on the first floor of the house (approximately 800 sqft). The hardwood floor was glued down quite well and seems to be difficult to remove.

 

Welcome to the forums.

This sounds reasonable to me, can you expand on what is concerning you?

 

My concerns are with settling. What happens to the house with almost the entire first floor ripped out. Secondly, load bearing walls usually sit on and end on joists. However non-load bearing walls do not. How are these going to be supported when the OSB is cut around them? They may settle months later and then I have cracked drywall all over the place.

 

I don't see this as an issue since the subfloor beneath the walls is not being removed (if I'm reading your description of the proposed solution correctly).

 

I agree with Mitch. They will only cut out the damaged wood from joist to joist and from wall to wall, leaving what is under the walls, since obviously they didn't damage it. Just ensure they cross at least 3 joists with their repairs. They should not place a piece of plywood across only two joists.
