What you can check yourself first

Not every sewage smell needs a plumber. The most common cause is simple, and you can check it yourself in a few minutes.

1

Find a rarely-used drain

A floor drain, a guest toilet, or a sink you barely use — that's where the trap seal dries out most often.

2

Pour in a glass of water

Pour water into every rarely-used drain and wait a couple of hours.

3

Smell still there? Call us

If the smell persists after adding water, the cause runs deeper — you'll need professional diagnosis.

⚠️ Important: Sewer gases can be harmful to health in high concentrations. If the smell is very strong or you feel unwell, ventilate the room and contact us right away.

Most common causes of sewage smell

Our plumbers diagnose the exact cause before starting work — not just offer a generic drain cleaning

Dried-out trap seal

The most common cause in rarely-used drains and floor drains

Damaged seal

Worn rubber gasket at the base of a toilet or at pipe connections

Venting problem

A blocked or incorrectly installed roof vent pipe

Cracked pipe

A damaged or cracked drain pipe under the floor or behind a wall

Partial blockage

An early build-up of grease or debris that doesn't yet stop drainage

Incorrectly installed plumbing

A fitting connected wrong or without sealant during a past renovation

Why diagnosis matters, not just masking the smell

Many people try to solve sewage smell with air fresheners or scented sprays — that masks the problem for a while but doesn't fix the cause. A dried-out trap seal is the simplest case and often fixable yourself. A damaged seal or a cracked pipe needs professional diagnosis and repair — ignored for long, it can get worse and cause moisture damage. Our plumber never starts with a ready-made solution — first we diagnose the real cause, explain what happened, and only then offer a fix with a clear price. 12-month warranty on all work.

Frequently Asked Questions

The most common cause is a dried-out trap seal (the water in a sink, floor drain or bath that hasn't been used for a while evaporates, letting sewer gas flow freely into the room). Other causes include a damaged rubber seal at the toilet base, a crack in a drain pipe, or a problem with the roof vent pipe.
Sewer gases (methane, hydrogen sulfide) can be harmful in high concentrations and cause headaches or nausea. A persistent smell shouldn't be ignored — the cause needs to be diagnosed and fixed.
Pour a glass of water into any rarely-used sink, bath or shower drain and floor drain. If the smell disappears after a couple of hours, a dried-out trap was the cause. If the smell persists, the cause is deeper in the system and needs professional diagnosis.
Diagnosis and fixing simple causes (a dried-out trap, a damaged seal) starts from €35. If deeper investigation or pipe repair is needed, we confirm the exact price before starting work.
Yes. A blockage usually means slow drainage or a complete stoppage. A smell without a blockage means water is flowing normally, but sewer gas is still reaching the room through some unsealed point or a dried-out trap — it's a different cause and a different fix.
