You may want to tip your junk removal team if they did an exceptional job. For instance, if they show up on time, are courteous and professional, take extra care not to damage your possessions and home, and leave a clean site afterwards, you may feel like giving them a tip. A reasonable tip might be $20 per crew member.
It’s also nice to tip them on especially hot days, or when the weather is inclement. You can also provide food and drinks for them.
