  Good Repair Guide: Timber Floorboards

Timber Floorboards-cover-200x262.png

Tongue and groove (T&G) timber floors laid over joists are a typical feature of older New Zealand homes. From the earliest houses until 1970s, all houses had timber floorboards. In the earliest houses, boards were square edged and butted, but by the 1960s, steam-powered milling machines were producing T&G floorboards.

This Good Repair Guide describes the types of repairs that can be made where damage to floorboards is minor or localised. It does not cover major repairs or where the floor may need to be replaced as a result of subfloor or foundation failure.
