Drain Cleaning & Sewer Drain Clearing
Slow drains, recurring clogs and sewer backups should be cleared and diagnosed, not simply pushed farther down the pipe. Canada Waterproofers clears blocked drainage lines and uses camera inspection to determine what caused the restriction and whether the pipe itself needs further attention.
Drain cleaning should restore flow and tell you why it stopped
A blocked drain is a flow problem. Somewhere between the fixture and the sewer connection, wastewater is being restricted by material inside the pipe or by a condition affecting the pipe itself.
Some clogs are straightforward. Hair, grease, soap residue or other buildup can restrict a local branch line and may be cleared mechanically.
Other blockages are symptoms of a larger problem. Tree roots, heavy scale, displaced joints, damaged pipe or a partially collapsed sewer can produce repeated backups even after flow is temporarily restored.
This is why recurring drain problems should not be treated as an endless cycle of clearing the same blockage. Once the line is open, inspection can help determine whether cleaning solved the problem or whether the drain itself requires repair.
If sewage or wastewater is actively entering the basement, review our emergency service information and limit use of affected fixtures until the drainage problem has been assessed.
Signs a drain line needs attention
The number of affected fixtures and where the problem first appears can help narrow down the part of the plumbing system that needs to be checked.
Slow Drain
Water takes noticeably longer to leave a sink, shower, tub or floor drain.
Floor Drain Backup
Water or sewage rises through a lower-level floor drain instead of flowing normally toward the sewer.
Multiple Drains Affected
Several fixtures draining poorly at the same time can indicate a restriction farther downstream.
Complete Blockage
Wastewater cannot pass the restriction and may begin backing up through the lowest available fixture.
Root Intrusion
Roots can enter through openings or joints in buried sewer pipe and create recurring restrictions.
Recurring Clogs
A blockage that repeatedly returns can justify camera inspection to check for a persistent pipe condition.
The cleaning method should match the line and blockage
Different drain restrictions require different tools. The objective is to restore flow without assuming every blockage should be treated the same way.
Drain Augering
A rotating drain cable can mechanically break through, retrieve or clear obstructions inside suitable drainage lines.
- Common local and branch-line clearing method
- Useful for many physical obstructions
- Different cable sizes suit different drain lines
- Condition of the pipe still matters
Hydro Jetting
High-pressure water can scour suitable drain and sewer lines to remove accumulated material from the inside pipe wall.
- Useful for grease and accumulated deposits
- Can provide more complete pipe-wall cleaning
- Equipment and nozzle are selected for the line
- Pipe condition should be considered first
Sewer Camera Inspection
After flow is restored sufficiently for inspection, a drain camera can show conditions inside accessible parts of the pipe.
- Helps locate recurring restrictions
- Can identify visible roots or damaged sections
- Helps distinguish cleaning from repair needs
- Provides evidence for larger repair decisions
Why camera inspection matters after a blockage
Clearing restores flow. Inspection helps answer the second question: why did the line block in the first place?
What different drain symptoms may indicate
The symptom does not prove the cause, but it helps determine where the assessment should begin.
| What You See | Possible Direction | Next Step |
|---|---|---|
| One sink or tub drains slowly | Local fixture or branch-line restriction | Drain cleaning and local inspection |
| Several fixtures drain slowly | Larger branch or building-drain restriction | Main-line drain assessment |
| Sewage rises through basement floor drain | Downstream blockage or sewer backup | Drain and sewer assessment |
| Backup occurs during major storms | Sewer surcharge or other drainage condition | Check sewer conditions and backwater-valve protection |
| Same sewer blockage keeps returning | Roots, scale or damaged pipe may be involved | Camera inspection after clearing |
| Clear water appears at foundation wall or floor joint | May be groundwater rather than a sanitary drain clog | Basement leak assessment |
How a blocked drain is assessed and cleared
The process changes with the line, blockage and pipe condition, but the sequence should move from symptom to access, clearing and diagnosis.
Identify Symptoms
We determine which fixtures are affected, when the blockage began and whether sewage backup is occurring.
Determine Access
The appropriate cleanout, fixture connection or other access point is selected for the affected line.
Clear the Restriction
Mechanical clearing or another appropriate cleaning method is used based on the drain and blockage.
Verify Flow
Drainage is checked after clearing to confirm that wastewater can move through the line.
Inspect the Cause
Where applicable, camera inspection helps determine whether the pipe needs cleaning only or further repair.
When drain cleaning is enough and when it is not
Cleaning removes restrictions inside a usable pipe. It cannot restore a pipe that has structurally failed.
Drain Cleaning May Be Enough
Cleaning may solve the immediate problem when the drain pipe remains serviceable and the restriction is primarily material inside the line.
- Local debris accumulation
- Grease or organic buildup
- Some removable root intrusion
- Scale or deposits that can be safely cleared
- A one-time obstruction without visible pipe failure
The Pipe May Need Repair
Repeated cleaning is not a structural repair. If inspection identifies significant pipe damage, the affected section may require repair or replacement.
- Collapsed or severely deformed pipe
- Displaced or open joints
- Significant cracking
- Repeated root entry through damaged sections
- Persistent blockage caused by pipe condition
What does drain cleaning cost?
The price depends on the affected line, access, blockage type, equipment required and whether diagnostic camera work or additional sewer service is needed.
Basic drain maintenance matters
Not every blockage is preventable, especially when buried pipe condition or tree roots are involved, but what enters the drainage system still matters.
Active sewage backup is different from a normal slow drain
If wastewater or sewage is entering the basement through a floor drain, toilet, shower or another fixture, reduce use of the plumbing system and keep people and pets away from contaminated water. An active backup should be assessed promptly. See emergency service .
Drain problems can overlap with sewer and basement-water problems
The next service depends on whether the issue is a blockage, sewer backflow, damaged drainage or groundwater.

Drain Cleaning FAQ
Common questions about blocked drains, sewer cleaning, hydro jetting and camera inspections.
How much does drain cleaning cost?
Canada Waterproofers currently lists drain cleaning from approximately $150. Final pricing depends on the affected line, blockage, access, cleaning equipment required and whether additional diagnostic or sewer work is needed.
How long does drain cleaning take?
Many routine drain-clearing jobs can be completed in approximately one to two hours. More difficult blockages, limited access or additional camera inspection can require more time.
What causes a drain to keep clogging?
Recurring blockages can result from repeated buildup, roots, scale, poor pipe condition, displaced joints or other restrictions. A recurring clog should be diagnosed rather than repeatedly cleared without checking the underlying cause.
What is hydro jetting?
Hydro jetting uses high-pressure water and specialized equipment to clean suitable drain and sewer lines. It can remove grease and accumulated material from the inside pipe wall. The condition and type of pipe should be considered when selecting the cleaning method.
Is hydro jetting better than snaking a drain?
Neither method is automatically better. Mechanical augering can be appropriate for many physical obstructions, while hydro jetting can provide more extensive cleaning of suitable pipe. The correct method depends on the line, blockage and pipe condition.
Can drain cleaning remove tree roots?
Drain-cleaning equipment can remove or cut some root intrusion sufficiently to restore flow, but recurring root entry can indicate openings or defects in the sewer line. Camera inspection can help determine whether the pipe also requires repair.
Why should a sewer camera be used?
A camera can help identify visible root intrusion, displaced joints, damaged pipe and the approximate location of recurring drainage problems. This helps determine whether cleaning solved the problem or structural repair should be considered.
Is a floor drain backing up a waterproofing problem?
Sewage or wastewater rising through a floor drain points toward a plumbing or sewer problem rather than normal groundwater leakage. Clear water entering at the foundation wall or floor-wall joint should be assessed separately as a possible waterproofing or drainage issue.
Will a backwater valve fix a blocked drain?
No. A backwater valve is designed to help prevent reverse sewer flow. It does not remove a blockage in the building drain or sewer connection. A locally blocked line still needs to be cleared and diagnosed.
When does a drain need repair instead of cleaning?
Cleaning is intended to remove restrictions inside a usable pipe. If inspection shows collapse, severe deformation, significant cracking, displaced joints or another structural defect, repair or replacement of the affected pipe may be necessary.
