Often it's not a blockage — the cause can be a dried-out trap seal, a damaged gasket, or a venting problem. We diagnose the real cause and fix it, rather than just masking the smell
Santehniķis Rīgā diagnoses sewage-smell causes in apartments and houses across Riga — before any repair, we always explain what actually happened. Diagnosis starts from €35, with a 12-month warranty on all work.
Not every sewage smell needs a plumber. The most common cause is simple, and you can check it yourself in a few minutes.
A floor drain, a guest toilet, or a sink you barely use — that's where the trap seal dries out most often.
Pour water into every rarely-used drain and wait a couple of hours.
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.
Our plumbers diagnose the exact cause before starting work — not just offer a generic drain cleaning
The most common cause in rarely-used drains and floor drains
Worn rubber gasket at the base of a toilet or at pipe connections
A blocked or incorrectly installed roof vent pipe
A damaged or cracked drain pipe under the floor or behind a wall
An early build-up of grease or debris that doesn't yet stop drainage
A fitting connected wrong or without sealant during a past renovation
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.
