Water leaking into cupboards, is this really a big issue?

Often water damaged cupboards are an overlooked issue in the buyers eyes, as they are planning to replace the cabinetry in the near future.
The unseen issue however,  is where could the water damage have transferred to, once through the cupboard itself.
Leaking plumbing can be an easy fix, the difficulty is replacing the shelf or cupboard carcass that is built into a kitchen and the damage to the wall framing behind.
Mold is another major issue that is often not seen, as it grows in the dark wet spaces behind the cupboards and can be very bad for your health.
Unfortunately termites are also attracted to damp moist areas, so the possibilities of further damage to the wall framing is quite possible.
Tile damage due to moisture ingress behind the tiles can also lead to tile uplift and possible cracking due to the expansion of the wet materials.
Wet area Gyprock was a product that is highly effected by moisture, as are the glass insulation bats installed in the wall frame, that soak up and hold the moisture.
In general, if a building report has a leaking kitchen or bathroom plumbing fixture, you should always have caution with your purchasing decision or at least recognise the fact that it may be more expensive to repair than you may have thought.
