Module: Head flashings

General wear and tear in a house often results in damage to interior wall linings. Damage can range from repairable (a picture hook pulled out or a door handle through the wall) to the catastrophic (a major leak or structural failure). 

This Good Repair Guide outlines some options for repairing existing wall linings and guidelines for when to replace a sheet or larger area of lining.

Prefinished linings (such as melamine-faced boards) are not included in this guide.

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.

Moisture changes in the timber can cause floorboards to expand and contract, and timber flooring is also susceptible to minor damage such as scuffs and scratches.

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.
