If none of the methods above have solved the problem, it’s time to call a plumber. The cost of a professional plumber ranges anywhere from $145 to $333.
HomeAdvisor says,
"it costs an average of $226 to get a drain snaked professionally. That price can land anywhere between $145 and $333 depending on the simplicity or severity of the issue. Stubborn blockages or damaged parts can increase your repair bill.”
