I moved into my house (second hand/7 years old) last Oct. Few weeks in and discovered sewage pipe was blocked. Plumber came out and stated that blockage was due to incorrectly laid pipes. Got it cleared and same problem came back 6 mths later. Problem has arisen again and at this stage I need to find out whether developer is covered under homebond structural guarantee and also whether my house insurance would alternatively cover it. Has anyone similiar experience and can offer advise. Also apart from asking developer is there any other means of ascertaining whether he is covered under this guarantee. Thanks in advance
