Choosing a builder naturally requires some research. Don’t just check their credentials. Be sure to see what work they have done in the last 12 months. I have never seen a bad reference, so I don’t take too much notice of them. What’s important with a builder is his ability to communicate not just with you but equally with his contractors, plumber and electrician. Cross checking is also an important part of this process. Apart from word of mouth, check with HIA (Home Industry Association) MBA (Master Builders Association) and Department of Fair Trading, and under no circumstances should you consider an unlicensed builder or builder who does not have home warranty insurance.
