I've dealt with this before. Most surprise fees happen because of three things: going over the weight limit, keeping the dumpster longer than planned, or tossing in banned items like paint, tires, or mattresses. Before you Rent a Dumpster, ask about the weight limit, how many days are included, and what it costs if you need extra days. Get the total price in writing. Choose a dumpster size that matches your project instead of just picking the cheapest option. If it's too small, you might need a second haul. A reliable Dumpster Rental Company should explain this to you from the start. I used TDR Dumpster Rental for my garage cleanout, and the price they quoted was exactly what I paid. When you're ready to rent a dumpster, you can call them at +888-451-9297.
