‘While some leaks are obvious, other leaks or damp problems can be hidden behind walls, under carpets or in inaccessible spaces like roof spaces. Moisture testing helps to determine whether there are problems that cannot be seen by the naked eye. It also helps to confirm the extent of problems which are presenting other signs.
Three places moisture testing might find problems
In the roof
If the property roof is old or has damage then you may find there are leaking spots. Common areas for leaks include:
- around the flashing
- places where vents from bathroom fans, chimneys or heating ducts are present
- broken tiles or steel plates
- loose fixings
- places where water pools
Behind the walls
Behind the walls of any property, there are plenty of pipes that could have problems. With older houses – built in the 1970s and 80s – there is often a problem with the pipes used in plumbing. At the time Dux Qest pipes were one of the first brands of plastic piping used to replace old copper pipes for plumbing. Over time it became brittle and started to crack or break causing leaks. The product was discontinued in the late 80s but many homes still have some of this type of pipework.
You may also find moisture behind the walls in rooms such as bathrooms and kitchens if the wet areas have not been properly sealed or finished.
Under the floor
Leaky pipes can also cause dampness at floor level but this may also be caused by a problem with the substructure of your property. This might be because the foundations and base were not adequately prepared or because the structure is not properly sealed allowing water in. This is especially common around areas where outside decks have been installed.
InnoHome includes testing for all Auckland properties as part of an inspection
Because moisture testing is such a key component of a thorough inspection, we include it in all of our pre-purchase inspections carried out across Auckland.
In most cases, we carry out non-invasive moisture testing. This involves using a reader to gauge moisture levels and does not cause damage to the property. We also use thermal imaging to give us a clearer picture of the extent of any problems.
If the damp problem is severe, then invasive moisture testing may be necessary. This does cause some damage as small holes need to be drilled and then refilled after testing.
As with everything found in your inspection, moderate to high moisture readings are not necessarily a potential deal-breaker. Having this information upfront allows you to make an informed decision and possibly to negotiate remedial work or a reduction in price as appropriate.
If you are buying a property in Auckland, book a pre-purchase inspection with us and buy with confidence.
