Over the next few weeks I will be posting information about common issues to look for when purchasing a property built in 1970's, starting with general tips then moving onto more specific issues related to types of cladding etc.
(Please note this is not an advice but more of an answer to questions we are asked when dealing with properties).
Common issues:
- Look out for Weatherside cladding, which was made from wood fibres and glue. In many cases the glue failed, which let moisture come into contact with the wood fibre, and the cladding deteriorated.
- Look for original aluminium windows, which may need to be maintained or replaced.
- Look out for asbestos. Many buildings contain asbestos cement materials both inside and out. It was also used for sheds, garages and fences. Textured asbestos ceilings were also popular in living areas.
- Look for original, highly patterned vinyl floors, which can have an asbestos backing.
- Does the building have insulation and, if so, is it up to current standards?
(To read more about house insulation requirements visit the MBIE website.)
- Does the building have the original wiring or has it been updated?
- Lead-based paint was commonly used for both internal and external paintwork in this period and can cause serious health problems. It can be removed and painted over, but this needs to be managed carefully.
- Has the plumbing been replaced? If new plumbing was added in the 1980s, look out for Dux Quest piping, which may cause problems.
- Check for obvious structural issues, for example, sloping or sagging floors, cracks in the walls and buckling near windows and doors.
-The piles and foundations under the building can deteriorate over time, so check they are still in good condition and are properly braced for earthquakes.
- Borer can be found in building timber and can cause structural issues.
- A range of housing styles were built in the 1970s. This decade saw the development of speculative (‘spec’) houses by developers, typically built from standard plans, and some were not well suited for their sites.
For more information:
- Check the local council files, including the LIM report.
- Consider getting a property inspection by a qualified property inspector. Make sure the inspection includes looking for asbestos — some building inspectors exclude liability for asbestos, so if you suspect asbestos make sure you have hired an inspector who will look for it.
- Ask the real estate agent (or the seller if it is a private sale).
