Floorboards over floorboards

[rreanor]

I'm thinking of laying new hardwood flooring over existing old pine flooring in a living room, hallway and dining room, mainly to reduce drafts. In the winter I can feel cold air coming up through the cracks.

Below the existing floorboards are suspended joists and I'm guessing the bare ground, ventilation is afforded through various vents/air bricks to the outside, which is a fairly standard Victorian style.

I don't want to add underfloor insulation as it'll be major upheaval.

Will new floorboards on top of old floorboards create an issue? Before I moved in the entire area was carpeted for decades and the existing floorboards are in good condition.

Can't you just add underlay?

Underlay where?

Under the carpet that you didn't ask for, obviously

Yes, you can lay floorboards over floorboards at 90° to the original ones. You just have to bear in mind that the more even and solid your to-be subfloor is, the better the finished result will be.
