Introduction
Clogged drains are more than a nuisance. Left untreated, they can lead to foul odours, water damage, and even raw sewage backing up into your home. In Canada, drain cleaning is one of the most common plumbing services. This guide explains typical drain cleaning costs, the factors that change the price, and what to expect for both simple clogs and complex sewer line jobs.
Cost Overview
Most homeowners fall in the middle of the cost curve.
- Low (from $300): Simple sink or tub clogs cleared with a hand auger.
- Typical ($450–$800): Fixture or branch lines requiring a machine auger.
- High ($800+): Main sewer line clogs, hydro-jetting, or after-hours emergency service.
Drain Cleaning Cost Table
| Service Type | Typical Cost Range | Notes |
|---|---|---|
| Simple sink or tub clog | $300–$450 | Cleared with small auger, minimal access |
| Toilet or floor drain | $350–$600 | May require toilet removal or clean-out access |
| Laundry or branch line | $400–$700 | Common in basements and long horizontal runs |
| Main sewer line | $600–$1,200 | Power auger with root-cutting head, deeper access |
| Hydro-jetting | $800–$1,500+ | High-pressure cleaning for grease, scale, or roots |
💡 Prices reflect Canadian averages across small and large markets.
Factors That Affect Cost
- Type of drain: Kitchen and vanity sinks are usually least expensive. Sewer mains are most expensive.
- Location of clog: Shallow fixture clogs cost less. Deep or underground blockages cost more.
- Equipment used: Hand auger is cheapest. Power auger and hydro-jetting add cost.
- Condition of pipes: Collapsed, corroded, or offset pipes increase time and complexity.
- Timing: After-hours, weekend, and holiday calls add premiums.
- Access: Clean-outs, tight cabinetry, and finished basements can affect labour time.
Scenario Examples
Basic Drain Cleaning (from $300)
Shallow sink or tub clog cleared with a hand auger.
Time: about 45 minutes.
Typical Drain Cleaning ($450–$800)
Power auger clears a laundry or floor drain through a clean-out.

Case Study: Real-World Example
A homeowner in Calgary noticed a basement floor drain backing up during laundry. A plumber inspected and found tree roots partially blocking the sewer main. Using a power auger with a root-cutting head, the plumber cleared the blockage in 90 minutes.
- Service: Sewer main cleaning
- Equipment: Power auger with root cutter
- Total cost: $620
- Result: Restored flow and avoided a potential multi-thousand dollar excavation
DIY vs Professional
| Option | Cost | When It Works | Risks |
|---|---|---|---|
| Plunger | $0–$20 | Minor sink or toilet clogs | Limited reach, may not hold |
| Hand snake | $20–$50 | Small clogs near the fixture | Can scratch or damage piping if forced |
| Chemical cleaner | $10–$30 | Rarely a lasting fix | Corrodes pipes, unsafe for plumbers, environmental impact |
| Professional auger | $300–$800 | Most residential clogs | Safe and effective when used by a pro |
| Hydro-jetting | $800–$1,500+ | Roots, grease, scale in sewer mains | Requires proper access and assessment |
👉 STOP point: If multiple fixtures back up or sewage enters the basement, call a licensed plumber immediately.
Estimates Disclaimer
💡 Estimates only. Prices exclude after-hours premiums, permits, camera inspections, cleanup, and specialized parts. Minimum service charge is $300 before tax. Actual costs vary by site conditions and location.
What’s Not Included
- Pipe replacement if collapse or corrosion is found
- Drain camera inspection, typically $200–$400 extra

Pro Tip
Schedule preventative auger service if you have mature trees near your line. Cutting roots annually is cheaper than dealing with a full backup.
Warranty Notes
- Many plumbers offer a limited workmanship warranty, often 30 to 90 days.
- Warranties do not cover new root growth or future grease buildup.
- Keep receipts for insurance and maintenance records.
Eco Angle
Hydro-jetting uses only water under pressure, so it avoids harsh chemicals that can harm pipes and local waterways.
