who to call to investigate crackling/squeaky noises on wooden floor on our upper floor

[Fionahuynh]

Since January 2022, our wooden floor on our double story house started making crackling noises when we step into our 2 bathrooms.  The noise is worse as we walked into our bathrooms the first thing in the morning,

Over the time of 3 years, the noises have spread out to other areas outside the bathrooms area as well.  We can even hear squeaky noises from downstairs as someone walking on our upper floor.  
Please help me to look for which professional trade people that I can get to have a thorough investigation on this matter.  I am so concerned t if this is left unchecked, we may ending up with a major structural problem.  This problem has caused so much stress on me over the last 3 years and now it has started to affect my health.

Thank you so much!

Welcome to the Bunnings Workshop community @Fionahuynh. It's terrific to have you join us, and many thanks for your question about squeaking noises.

Since your upper floor has a wooden subfloor with, I presume, tiles over the top, at least in the bathrooms, the crackling noises could be due to movement in the subfloor, loose tile adhesive, or changes in humidity affecting the timber. Given that the issue has spread over time, it's best to have it checked sooner rather than later.

A builder or carpenter would be the best first point of contact to assess the subfloor for movement. If they suspect structural issues, they may recommend a structural engineer for a more in-depth inspection. A tiler could also help determine if the tiles or their adhesive have loosened over time. Getting a professional to investigate now can help prevent any further deterioration. 

Please let me know if you have any questions.
