Excess dampness in the foundation of a house is one indication that reblocking or restumping work needs to be done.
Additional signs to look for are:
- Floors that are sloping or uneven
- Cracks appearing in tiling or in plaster work
- Doors sticking or not closing properly
- Timber stumps starting to decay
- Floors becoming loose or bouncy
Reblocking or restumping is recommended for any house that was built before 1970, even if it is not yet showing any of the above signs.
