SUB-FLOOR REPAIR

Experienced and professional sub-floor repair in Melbourne

Timber floors that bounce or creak under tread may indicate the support timbers have been damaged as a result of continuous exposure to sub-floor dampness. 

Besides the obvious unsound feel of the floor, other telltale signs include: 

  • The flooring has dropped from the underside level of the skirting boards 
  • There is quad beading or the like at the toe of the skirting boards to disguise a subsidence gap 
  • The nails on the polished boards have rust marks around them 
  • The carpet is dark stained around the edges

If the floorboards are particularly spongy around the edges of the room it may be likely that the joist ends have shrunk and are failing to support the floor adequately, indicating that tailing may be required. Floors that have excessive bounce in the middle of the room may have bearers that are not being adequately supported by the stumps, indicating restumping is required. 

Intermittent or continuous sub-floor odour may be a symptom of a damp hostile sub-floor environment. 

Flooring timbers will eventually fail if subjected to prolonged exposure to sub-floor dampness. The deterioration may be accelerated under areas of non-vapour transmitting floor coverings such as polyurethane based polished floor finish or tiles.
