Flooring – Strange intermittent popping sound from floorboards

flooring

I hear a strange sound from the floorboards. I made a recording of it which you can hear here:

Here is what I know about the sound:

  • It happens only at night (which makes it specially annoying since it disturbs my sleep and makes it harder to diagnose).
  • It happens at irregular intervals. Sometimes I will go hours without hearing it and sometimes I will hear it several times in a minute.
  • It comes from a part of the floor which has loose floorboards.
  • It comes from a part of the floor next to the heater.

I have a wooden floor. What could be causing this sound?

Like Kris said it's most likely: Expansion and contraction due to fluctuating temperatures and humidity levels.

There are several options to address this: If you own the house, and want "a squeek free floor" hire it out to a local handyman. Otherwise you will play chase the squeek for weeks with a mix of screws, nails, glue and braces.

If you don't own the property, call the owner.
