If you’re in need of a construction dumpster rental service, you want to ensure you choose the right company for your needs. You do this by asking the right questions. One of the first you should ask is what size containers they offer. You want to ensure they have the right size for your needs, whether that’s a small 10-yard dumpster or a giant 40-yard dumpster. You’ll also want to be clear on how long you can keep the rental for, and what it would cost to extend that timespan if needed. You should also ask what type of waste is and is not allowed in the dumpster. Most rental companies will have a list of forbidden items and substances that can result in grave penalties if the rules are broken.
