Most Drain Smells Aren't What You Think
Air freshener doesn’t fix drain smells. Bleach makes them worse. The real cause is almost always one of four things — and finding the right one is the difference between a permanent fix and a smell that comes back every two weeks.
We’ll come out, diagnose it properly, and quote a fixed price for the actual repair. No call-out fee, no guesswork.

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 Reading Homeowners Say After A Smell Fix
Eleanor T. — Reading
A horrible drain smell in the utility room for months. Three plumbers tried different things, none worked. Drainage Reading found a cracked vent pipe in the wall, fixed it, smell gone in a day.
Raj M. — Reading
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. — Reading
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. — Reading
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?
The visit and diagnosis are free until we agree the work. Once the cause is identified you get a fixed-price quote — most fixes are £85–£250.
Can't I just pour bleach down the drain?
Bleach masks bacteria smells temporarily but doesn’t fix dried traps, blocked vents or cracked pipes — which are the real causes.
Why does my drain only smell at certain times?
Usually wind direction (vent stack issues), warm weather (gas expansion), or after periods of low use (dried traps). The pattern tells us a lot.
How long does a smell fix take?
Most fixes are completed in one visit, same day. CCTV-confirmed pipe damage may need a return visit for the repair.
Can a smelly drain be a health risk?
Yes — sewer gas (hydrogen sulphide and methane) is harmful in concentration. It’s worth getting any persistent drain smell properly diagnosed.
Will the smell come back after you fix it?
Not if we identify the root cause. We re-test before leaving and back our work with a 12-month workmanship guarantee.
Do you cover all of Reading?
Yes — every Reading postcode and surrounding RG areas.
