How much does it cost to unclog a drain professionally?

Professional drain unclogging from Brothers Plumbing, Heating, and Electric is quoted after diagnosis, because price varies by clog type, access, and the method needed to clear it. Most simple sink, tub, or toilet stoppages are resolved with drain cabling, while heavy grease, sludge, or roots can require hydro-jetting or a video camera inspection to verify the fix.

We handle these jobs across the Denver metro, including Centennial, with options that match the problem instead of a one-size-fits-all approach. Available savings may apply, such as $50 off work performed and $150 off a video camera inspection and location, per current coupons.

What most affects cost:

• Where the blockage sits (single fixture vs. main sewer line)
• Severity and material (hair/soap vs. grease or roots)
• Access points (cleanout available or not) and add-ons like camera inspection
• Follow-up repairs if damage is found

If water is backing up or multiple drains are slow, book a professional assessment before using chemical cleaners. <br/> Updated: 2026-03-24 <br/> Need help in Centennial, CO? Call (720) 994-7055 or book online.
