By far, the biggest factor that is used to determine the cost of the service is the size of your grease trap. Grease traps in Pendleton come in a variety of sizes. The larger ones need more labor time to clean. Thus, it's only reasonable that the bigger the size, the more expensive the service gets. Another factor that greatly affects the final price of the clean-up process is the kind of grease trap you have. Some grease traps are simple, and these are the ones that are cheaper to clean. For complex grease trap setups, it will take significantly more time as the professionals need to ensure that everything is clean without compromising any parts.
