When it comes to tipping your movers, there is no one-size-fits-all answer. Generally, the industry standard is to tip based on a percentage of the total cost of the move, with 15-20% being the average. However, you can also choose to give a fixed tip to your moving agents. It's important to use your best judgment when deciding how much to tip.
Factors such as the difficulty of the move, the appearance of the movers, and the quality of service should all be taken into consideration. For instance, if your move involves heavy items like pianos or closets, or if there are architectural obstacles like steep terrains or multiple flights of stairs, then you may want to increase the tip amount. On the other hand, if your move was excessively delayed, if your property or belongings were damaged, or if you received poor service, then tipping is not necessary. At the end of the day, it's up to you to decide how much to tip your movers.
But keep in mind that they are doing a difficult job and deserve recognition for their hard work.
