Will you remove the subfloor to raise this floor to be level with the other rooms?

I’m going to raise this floor so it matches the height of the other rooms. Should I take out the subfloor?

If you don’t take it out, you might end up having to tear out all the new joists to make them the same height. It’s fine to just leave it there and screw the new joists to the old ones.
I’m starting to consider this. The old floor is really stuck down, it’s going to be tough to remove.
Certainly, you’ll definitely save some time.
Perhaps you could repurpose the flooring on top of the new joists to save some money.
Hey Jason, I really admire your mindset

Definitely not
I would recommend framing over it instead and adding a new subfloor that is flush with the one you are matching. You could consider placing the new members over the old joists for added strength

I’d prefer to nail or screw the cross joist instead of aligning it parallel to the current one directly above the subfloor. Cut the joists to ensure everything is level.
Sure, go ahead and take it out then add 1/4 inch Sheetrock on top of the joist
I would leave it as is, no need to do extra work. Just use the necessary floor joist and 3/4″ subfloor to match the existing floor.
Nope. Just remove it all. Make sure to address both layers and joists to avoid double squeaking. Yes, squeaking is a legit term used by top engineering firms 😂 Also, place the new joists perpendicular to the lower ones or directly over them.
Is the man! I’ve been finding and fixing squeaks on the second floor without the ceilings in place. Absolutely loving my silent floors now.
No, but consider leaving a fake skeleton or something down there as a surprise for the next person.

I would just let it be and add onto it
In this case, they’re known as sleepers. It’s important to glue them down when installing. It’s a fairly simple and manageable project. You might also want to consider adding some electrical wiring for lamp outlets in the new floor.
Thinks going electric is a fantastic idea!
I always make sure I have easy access to the new floor from underneath.
My response might change based on whether the subfloor is securely glued and the level of squeakiness.
Ryan used a lot of glue. No squeaking.
Just go ahead and cover everything with glue. You’ll be fine.
I’m curious about the construction process, can you share some details?
You don’t necessarily have to, but if you ever need to access it for any reason, you would only need to remove one subfloor. Personally, I would need a compelling reason to do so. Good luck!
Why does this have to be kept anonymous?
Chances are it doesn’t
Just leave it as is. Check for any creaking sounds and ensure it’s perfectly level. Best of luck
I wouldn’t do that. I’d simply even it out.
I wouldn’t recommend it. The plywood you currently have will likely start squeaking over time, and accessing it will be difficult.
Sure thing, if you’re looking to have all the concrete in the basement.
