Constant hum in ground floor apartment
Hello,
We live in a ground floor apartment. When our upstairs neighbour is in (they usually live abroad), a loud hum is audible in all areas of our flat. She did have an electrician come and investigate, which he said the pressure had dropped, however it hasn’t helped. I wonder what it could be / how to go about getting it fixed quickly. Thank you!
Expert Trade Answers
"From what you’ve described, the fact the humming only occurs when your upstairs neighbour is in suggests it’s likely related to something in their flat rather than your own installation. The most common causes in situations like this are things like water pumps, extractor fans, or appliances (such as a boiler or fridge) creating vibration that’s travelling through the structure of the building.
If an electrician has already attended and mentioned pressure, they may have been referring to water pressure or a pump system — sometimes these can cause a constant low-frequency hum if they’re faulty or mounted directly onto the structure without proper isolation.
The best way to resolve this quickly would be to have access to the upstairs flat while the noise is present, so the source can be identified directly. In many cases, the fix is straightforward once located — such as adjusting or replacing a pump, or adding anti-vibration mounts.
I’d be happy to take a look and help pinpoint the exact cause if you’re able to arrange access."

"Hello,
This is most likely due to an appliance or appliances like a fridge freezer or/and ceiling fans that maybe drawing power constantly. Agreeing with the comment below- a good place to start would be to turn off appliances 1 by 1 to try and trace the culprit."
