Main Sewer Line Clearing in Whitby

How the job is handled
After opening the main cleanout, which normally sits low in the basement toward the street, we feed a heavy sectional cable fitted with a blade matched to the 4-inch pipe. The cable tells a story: roots tear differently from grease, and a sudden hard stop often marks a collapsed or offset joint.
Once flow returns, a camera run is the sensible next card whenever roots came back on the blade or the house has backed up before. Clearing restores flow; a camera tells you why it stopped.

Symptom, cause and fix
| What you see | Usual cause | What we do |
|---|---|---|
| Wipes and paper in the line | Flushing products not made for drains | Cable clear, then talk about what goes in |

| Belly holding water | Pipe has sunk under the yard | Camera locate the low spot for a spot repair |
Local card: Whitby houses
Mature trees along older Whitby streets send roots into clay and older joint connections looking for moisture. Newer subdivisions with PVC laterals see fewer roots, but construction debris and settled pipe can still cause backups in the first years.
The visit, in order
- Cleanout opened and area protected
- Machine cable run to and through the blockage
- Several fixtures run together to confirm flow
- Recommendation on camera work noted on your card
Ring us when
Stop using water as soon as a floor drain backs up. Each flush or wash cycle simply sends more onto the slab. Then call.
Common questions
Who owns the sewer pipe outside?
Generally the homeowner owns the private side to the property line and the municipality owns the portion beyond it. Confirm the specifics with the Region of Durham.
Will clearing fix roots permanently?
No. Cutting removes the roots inside the pipe, but they can return through the same joint. Lasting fixes involve repairing that joint.
