In case of construction defects with your newly bought property, remember that you may take the builder, developer and the architect to court within 10 years of substantial completion of the home. If your home was built more than 10 years ago, you only have 6 months, after signature of the deed, to claim against the seller for the defects arisen.
The terms of guarantee for construction defects applicable to new houses, are also applicable to second hand properties where construction defects had arisen.
