Drain Odor & Back-Smell Removal

Inspect common odour sources such as drains, traps and joints

Drain odours may come from a dry U-trap, damaged pipework or joints, a poorly sealed floor drain or accumulated residue, and may also involve concealed or shared pipes. We inspect accessible points and explain likely sources, limitations and proposed work; the outcome depends on the underlying cause and repairable scope.

Frequently Asked Questions

What are the limits of an odour investigation?
An odour may come from concealed or shared pipes, building gaps or another unit, so one visit may not identify or resolve it. We explain the accessible scope, proposed work and charges, without promising permanent removal in one visit.
Why does the smell return after using air freshener?
Air freshener mainly masks odour and does not repair a dry trap, damaged joint or build-up. Persistent smells need investigation, and some cases may require building management or another contractor.
Will you need to remove furniture or tiles?
In most cases, no. Our technician first inspects non-destructively; if localised work is genuinely needed, we quote and get your approval first.
