Bouncing 2nd Lvl Floors
We bought a remodel 16 years ago. The front 1/2 is over 100 years old with new dry wall, electric etc. The back 1/2 was new construction.
We have recently painted 2 upstairs bedrooms and pulled the carpet. One of the rooms in the older part of the house has a bounce in floor - not bad enough to crack the ceiling downstairs but the light fixture shake a little. The floor has tongue and groove wood flooring that is probably original to the house and no sub-floor.
How do we firm up the floor and make it more stable before replacing the carpet?
