What's Really Causing The Smell

Dried-Out Trap

Under a sink that's not used much. Water in the U-bend evaporates, sewer gas comes back up.

Blocked Vent Stack

The vent pipe on your roof has blocked. Common in autumn after leaf fall.

Grease Build-Up

Old grease coating the inside of the waste pipe, decomposing over time.

Cracked Pipe / Failed Seal

Sewer gas escaping through a damaged pipe under the floor or behind a wall.

What MK Homeowners Say After A Smell Fix

Eleanor T. — MK

A horrible drain smell in the utility room for months. Three plumbers tried different things, none worked. Drainage MK found a cracked vent pipe in the wall, fixed it, smell gone in a day.

Raj M. — MK

Kitchen smelled like a sewer every morning. Turned out to be a dried trap under an unused dishwasher connection. Fixed in twenty minutes for the cost of a call-out.

Caitlin O. — MK

Smell coming and going from the sink for ages. They CCTV'd the line, found a grease coat further down, jetted it clear. Genuine fix, not a fragrance cover-up.

Bernard W. — MK

Knew something was wrong but couldn't pinpoint where the smell came from. Engineer was patient, methodical and actually solved it. Worth every penny.

Drain Odour FAQs

How much does a drain odour diagnosis cost?
We check the issue first, explain what’s needed, and confirm a fixed price before starting the work.

Bleach masks bacteria smells temporarily but doesn’t fix dried traps, blocked vents or cracked pipes — which are the real causes.

Usually wind direction (vent stack issues), warm weather (gas expansion), or after periods of low use (dried traps). The pattern tells us a lot.

Most fixes are completed in one visit, same day. CCTV-confirmed pipe damage may need a return visit for the repair.

Yes — sewer gas (hydrogen sulphide and methane) is harmful in concentration. It’s worth getting any persistent drain smell properly diagnosed.

We find the root cause, re-test before leaving, and stand behind our workmanship.
