Moving house can be a stressful situation. To make your life easier, find trustworthy and reliable movers. Adding unreliable movers to your list of things to deal with will make the move more expensive, not to mention draining emotionally, and you need all the energy you can get to manage such a big transition.
Some professional movers will take advantage of your situation and put pressure on you. To prepare, get 3 quotes for everything. Make sure there is an agreement they cannot get out of.
Some movers (called “removalists” in Australia) will come to your door on the day of the move and say that you have to add more money because you have more furniture than they thought when they gave you a quote. Or a cleaner might say, “Oh, I didn’t realize the carpet was so dirty” and since you are rushed to get it done on the day, you have no choice but to pay the extra before they are willing to start working.
