How much does it cost to unclog a drain professionally?

Professional drain unclogging from Lanz Plumbing, Heating & Cooling, Inc. is priced after diagnosis with flat-rate pricing, and the final cost is confirmed on site. Most cost differences come from where the blockage sits and which clearing method is needed; a simple fixture clog usually costs less than a main sewer backup that requires advanced cleaning. We routinely handle kitchen, bath, and main-line clogs in the Monticello area with the tools to resolve both routine and heavy obstructions. If a clog points to damage, our team can move from cleaning to repair using options that include trenchless methods.

Cost typically varies by these factors:

• Location of the blockage (single drain vs main sewer)
• Method required (snaking, hydro jetting, or descaling)
• Severity and cause (roots, grease, or scale)
• Access and add-ons (cleanout needs, camera inspection, or after-hours service)
