Rotten floorboards

Hi not sure which trade category this is, but we have rotten floorboards in our back downstairs room and also by the front door.
Is replacing by floorboards or concrete the answer? Front room its only a few boards, also possible damp proofing.
Many thanks

As far as replacement of boards a carpenter could do that
However a proper builder would be required to investigate the damp issues and resolve that first"

If floorboards are rotten your need to check the joists underneath. If you have floor boards I’d assume you have a vented floor (check out side for air bricks, they have a grid with holes) if so you don’t want to concrete it as this will cause damp. You can insulate between the joists and use expanding foam to seal the edges this will stop rising damp unless it’s behind your plaster. Also if replacing all floor boards I recommend fitting chip board flooring as if fitted properly it won’t creak or allow drafts. Whereas for the front room I’d just replace the joists. Easy enough for a DIYer if not a chippy like me can help.
Hope this helps"

"Hello, the rotten boards should definitely be replaced with new ones, but it is more important to find the cause, because the fact that the boards are rotten is only a symptom, I would have to see it . Pozdrawiam Lukas"

"Usually, the floor boards rot from moisture because they are not protected and the tree rots quickly.
it would be good to have insulation in the floor you can replace rotten boards with new ones.Thanks"
