Service · Calgary
Your main sewer line carries every drop of wastewater from the property to the city connection. When it restricts, every fixture feels it. We clear the main line from the cleanout to the city side, remove roots, grease and debris, and can verify the result on camera.
- Whole-house drainage restored
- Lower risk of basement backups
- Cause explained, not just cleared
Overview
The main sewer line (or lateral) is the single pipe that carries all wastewater from your home or building to the city sewer. Every toilet, sink, tub and floor drain empties into it — so when it restricts, the whole property is affected.
Main line cleaning clears the full length of that pipe from the cleanout to the city connection, cutting through roots and removing grease, paper and debris. A camera run afterward confirms the result and shows what caused the problem.
No clear, no clearing charge
On eligible standard blockages.
Spot Problems Early
Problems build up gradually. Watch for these warning signs before a small issue becomes a backup.
Multiple slow drains
Several fixtures slow at the same time.
Floor drain backups
Water rising in the basement drain when the washer runs.
Gurgling toilets
Especially when a tub or washer drains.
Sewer odours
Smells near the floor drain or cleanout.
Water at the cleanout
Standing water visible when the cleanout is opened.
Lush patches in the yard
Can indicate a leak in the line underground.
Root Causes
Understanding the cause is how we stop a problem from coming back — not just clear it for today.
01Tree roots
The most common cause of main line blockages in established neighbourhoods.
02Grease & paper build-up
Waste that collects at low spots and joints.
03Pipe sags
Low sections where solids settle out.
04Foreign objects
Wipes, toys and hygiene products that catch debris.

Our Process
Your main sewer line carries every drop of wastewater from the property to the city connection. When it restricts, every fixture feels it. We clear the main line from the cleanout to the city side, remove roots, grease and debris, and can verify the result on camera.
Locate
We find and open the main cleanout and confirm the line runs where we expect.
Clear
A heavy-duty cable machine or jetter opens the line and removes build-up along its length.
Verify
Water testing and an optional camera run confirm the line is flowing and show what caused it.

Most main lines are cleared in one visit. Time depends on access, line length and what's causing the blockage.
A working, accessible cleanout makes the job faster. If there isn't one, we may need to access the line through a toilet or other fixture, which can add cost.
When appropriate — for recurring or unexplained blockages — a camera confirms the line is clear and shows what caused the blockage — roots, a sag or damage — so you can plan ahead.
Yes, for eligible standard blockages: if we can't clear it, we waive the clearing charge.
