A sewage smell in the bathroom is usually caused by sewer gas escaping past a trap or vent issue, or by a developing drain problem. In North Vancouver homes with basement suites, renovations, or older venting layouts, odours can be intermittent and misleading. We confirm the most likely cause and recommend the most direct fix.
Every visit includes a $99 call-out fee for a visual first check.

If you also have slow drains, gurgling, or multiple fixtures acting up, see Drain cleaning North Vancouver or Sewer backup repair North Vancouver. For urgent wastewater overflow concerns, contact Emergency Plumbing.
Sewer gas should be blocked by a water-filled trap and safely vented through the roof. When something fails in that system, odours can enter the home.
If a trap is dry or not holding water, sewer gas can pass into the bathroom. This can happen with little-used fixtures.
A compromised toilet seal can allow odours to escape, sometimes without obvious water leakage.
Blocked or poorly performing vents can cause traps to siphon, leading to intermittent odours and gurgling.
Build-up in the drain line can slow drainage and contribute to odour, especially when multiple fixtures share a branch line.
Moisture behind finishes can mimic sewage odour. If odour is unclear, leak confirmation may be needed.
Basement bathrooms and floor drains can be a common odour source when trap seals fail.
The goal is to confirm the true source of the smell, then recommend the most direct correction without guesswork.
We confirm where and when the smell occurs, including after shower use, flushing, or periods of non-use.
We check likely sources such as toilet base, sink trap areas, floor drains, and visible vent connections where accessible.
We look for slow drainage, gurgling, or other signs that suggest venting or drain restriction is contributing.
If the fix is visible, we provide clear upfront pricing. If confirmation requires further access or tools, we confirm Investigation Time before proceeding.
We complete the approved correction and verify improved performance and reduced odour conditions.
