Hello readers,
I have purchased an older house, built around 1910, and I hope to get some advice here.
Unfortunately, I found that the wooden floors installed are extremely wet and even have mold. I want to remove them because they are in direct contact with the ground and are rotten.
Now my question is how I should proceed, what I need to consider, and what the costs might be.
This is how I would do it:
Remove the floorboards
Excavate about 20 cm (8 inches) of soil, there is no basement under these two rooms
Install a filter layer and then a vapor barrier membrane
Build reinforcement and fill up with concrete to about 5 cm (2 inches) below the existing concrete base
Install vapor barrier and insulation, then finish with tiles
I estimate around €2000 without tiles for 2 rooms of about 45 m² (485 sq ft). umbau2.jpg
Is this cost estimate roughly correct?
I would appreciate your comments.
Best regards,
Denfer
