If you are asking how much it costs to unclog a drain professionally, you may be dealing with a slow sink, a backed-up tub, or a blockage affecting several fixtures. The price depends on where the clog is located, how difficult it is to reach, and whether the line needs standard cabling, hydrojetting, or a camera inspection.
Cardinal Plumbing Heating & Air Inc. provides upfront options after evaluating the problem. Below, we break down Cardinal’s typical drain and sewer pricing, the factors that affect your quote, and how to choose the right service without risking damage to your pipes.
Professional Drain Cleaning Costs in Northern Virginia
Cardinal’s typical pricing depends on the type and location of the blockage:
- Drain cleaning and repair: $350–$800
- Main line clog service: $800–$1,200
- Hydrojetting: $1,400–$2,600
- Sewer camera inspection: $600–$1,200
A standard sink, shower, tub, or toilet clog will usually fall under drain cleaning and repair. If several fixtures are backing up at once, the problem may be in the home’s main sewer line and require more extensive clearing or inspection.
Cardinal also lists a $97 service call, which is credited toward completed repairs. Final pricing is confirmed after a technician evaluates the line and explains the recommended options.
What Drives the Price
Several factors determine the final cost of professional drain cleaning. Knowing them can help you understand why one clog may cost more to address than another.
- Location of the clog
- Fixture-level clogs are generally less involved than blockages deep in the main sewer line.
- Exterior cleanout access may make a main line easier to reach than removing a toilet or using another access point.
- Severity and type of blockage
- Hair, soap residue, food debris, and localized grease may respond to professional cabling.
- Heavy grease, sludge, scale, or root intrusion may require hydrojetting or additional diagnostic work.
- Number of affected lines
- One slow sink, tub, or shower usually points to a localized drain problem.
- Multiple affected fixtures may indicate a blockage in the main sewer line.
- Access and setup time
- A clear, accessible cleanout can reduce the amount of setup required.
- Limited access, finished areas, crawlspaces, roof access, or toilet removal can increase the scope of work.Diagnostics
- Advanced drain camera work pinpoints issues and documents the fix.
- Method and equipment
- Professional cabling is commonly used to break through localized obstructions.
- Hydrojetting may be recommended when buildup coats more of the pipe wall.
- Diagnostics
- A sewer camera may be used to identify roots, cracks, offsets, bellies, buildup, or collapsed sections.
- Underground locating may also be needed when planning a repair.
Price by Method: Snaking, Hydrojetting, and Camera Inspection
Different drain problems require different tools. A technician should evaluate the symptoms and pipe condition before recommending a method.
- Drain clearing or cabling: $350-$800
- Commonly used for clogged sinks, tubs, showers, toilets, and other fixture-level drain problems
- Best for hair, soap buildup, food debris, localized grease clogs, and other soft obstructions
- Final pricing depends on the access point, number of affected lines, blockage type, and pipe condition
- Main line clog service: $800-$1200
- May be needed when multiple fixtures are slow, toilets are gurgling, or wastewater backs up into a tub, shower, or floor drain
- Pricing depends on cleanout access, the clearing method, camera needs, and whether roots or pipe damage are involved
- Removing a toilet or using another access point may increase the scope of work
- Hydrojetting: $1,400–$2,600
- Uses high-pressure water to remove grease, sludge, scale, roots, and recurring buildup from pipe walls
- Pricing depends on pipe size and length, the type of buildup, equipment needs, and access
- Older or damaged pipes may require a camera inspection before high-pressure cleaning is performed
- Sewer camera inspection: $600–$1,200
- May identify roots, cracks, offsets, buildup, bellies, separated joints, or collapsed sections
- Commonly recommended for recurring clogs, main line symptoms, suspected pipe damage, or repair planning
- Pricing depends on the access point, line length, locating needs, and whether a toilet must be removed or roof access is required
Kitchen, Bathroom, and Main Line Scenarios
Real-world scenarios can help you understand which service and price range may apply.
- Kitchen sink with recurring slow drain
- Likely service: Professional drain cleaning or cabling
- Typical Cardinal range: $350–$800
- Grease, food residue, soap, and disposal debris commonly collect inside kitchen branch lines
- Hydrojetting may be considered if heavy buildup causes the clog to return
- Single bathroom sink, tub, or shower full of hair and soap scum
- Likely service: Professional drain cleaning or cabling
- Typical Cardinal range: $350–$800
- Hair, soap scum, toothpaste, and shaving products often create localized bathroom drain clogs
- One affected fixture generally points to a branch-line problem rather than a main line blockage
- Toilet backing up with multiple fixtures affected
- Likely service: Main line clog clearing
- Typical Cardinal range: $800–$1,200
- A main line problem may be present when flushing a toilet causes water to rise in a tub or several drains stop working
- A camera inspection may be recommended if the clog is severe or keeps returning
- Main line with heavy grease, sludge, scale, or roots
- Likely service: Hydrojetting
- Typical Cardinal range: $1,400–$2,600
- Hydrojetting may provide a more thorough cleaning when buildup coats the pipe walls
- The line may need to be inspected first to confirm that it is suitable for high-pressure cleaning
Emergency, After-Hours, and Weekend Rates
Drain and sewer backups do not always happen during normal business hours. Cardinal offers 24/7 emergency service for urgent plumbing problems.
Same-day appointments may also be available when scheduling permits. Ask about current availability and any applicable charges when you schedule. Cardinal will explain the recommended service and pricing before approved work begins.
Call promptly if you notice:

- Several fixtures that will not drain
- Wastewater entering a tub, shower, or floor drain

When a Simple Clog Becomes a Repair or Replacement
Many drain problems can be handled through professional cabling or hydrojetting. However, a camera inspection may reveal pipe damage that cannot be corrected through cleaning alone.
- Cleanout installation or modification
- A cleanout may be recommended when the sewer line is difficult to access
- Pricing depends on location, depth, pipe material, and surrounding surfaces
- The cost is confirmed after an on-site evaluation
- Drain repair
- Cracks, separated joints, corrosion, leaks, or damaged pipe sections may require repair
- Pricing depends on the material, location, access, and length of the damaged section
- Repair options are explained before work begins
- Sewer line repair or replacement
- A collapsed, severely offset, or extensively damaged line may require sectional repair or replacement
- A camera inspection helps identify the location and severity of the damage
- Final pricing is based on the repair method, line depth, access, and project scope
Our advanced drain camera helps pinpoint the problem so you avoid guesswork and unnecessary digging.
The Professional Process You Can Expect
The exact process depends on the symptoms and type of blockage, but a professional drain visit may include:
- Initial evaluation
- Review the symptoms and determine which fixtures are affected
- Identify available drain or sewer access pointsShoe covers, floor protection, and a quick walkthrough
- Diagnosis
- Determine whether the issue appears limited to one fixture
- Check for signs of a branch-line or main sewer line blockage
- Clearing the clog
- Use professional cabling for localized or soft obstructions
- Recommend hydrojetting when heavier buildup coats the line and the pipe is suitable
- Verification
- Run water and test affected fixtures after clearing
- Use a camera when needed to evaluate recurring problems or possible pipe damage
- Options and pricing
- Run water and test affected fixtures after clearing
- Use a camera when needed to evaluate recurring problems or possible pipe damage
6. Prevention tips and warranty
- Share practical steps to reduce the risk of another clog
- Explain any warranty that applies to the completed service
DIY vs. Professional Service: When to Call
Some simple fixture-level clogs may respond to basic steps such as removing visible hair, cleaning the stopper, or using a plunger correctly.
Avoid pouring harsh chemical drain cleaners into the line. They may not remove the full blockage, can create safety concerns during professional service, and may damage some older or deteriorated plumbing materials.
Call a professional when you notice:
- Multiple fixtures backing up at once
- Standing sewage in tubs, showers, or floor drains
- Gurgling sounds or toilet bubbles when another fixture drains
- Persistent sewer odors
- Recurring clogs that return within days or weeks
- Water damage around a drain or fixture
- Signs of roots, corrosion, or damaged sewer piping
A blockage affecting several fixtures is unlikely to be solved by repeatedly plunging one drain.

Smart homeowners want both value and a solution that addresses the actual cause of the clog.
