The best way to ensure you get the right (and best!) people for the job, is to ask around. Speak with your network of friends who have used certain tradespeople, or know people who are highly regarded, as this can uncover a goldmine of excellent, skilled people who can make all the difference to your home renovation.
Communication is key. Get your tradies involved early on, especially with a major renovation. Get your plumber or builder out early, before you buy anything to ensure you get their advice, preference and technical expertise. Often they will have preferred brands or products they recommend for a number of reasons, including durability, installation ease and flexibility, which in the end will save them time, and you money! This kind of insider knowledge is invaluable.
