The wooden floors typical of 1940s-60s houses often lack insulation, and some boards may be affected by borer, splitting or other damage.

Most 1940s-60s houses had tongue-and-groove wooden flooring supported on timber joists. Read more.

Common problems and remedies

Flooring should be checked for borer, rot or other damage such as splitting. Splitting occurs along the tongue and groove joints. Repeated sanding over time may also have exposed the tongue and groove joint. Options to repair damaged boards include:

  • replacing damaged boards with matching timber sourced from a demolition yard
  • replacing the flooring if in poor condition
  • installing overlay flooring over existing flooring that is structurally sound.

If a timber floor is in good condition, it can be sanded and polyurethaned or oiled to give a durable finish.

Houses of this era will generally lack underfloor insulation.
