Flooring issue - could be more?

Question

Hi there, looking for some advice. Over the past few months I’ve noticed that the floors throughout my house (upstairs, downstairs, and stairs) feel creaky and bouncy. It’s mostly carpeted and was re-carpeted last year. I’ve lived here for many years and this is a recent issue — or I may just be more aware of it now. When the new carpet was laid, thick wooden dividers between rooms were replaced with metal ones, and I wonder if that might have caused some shifting. I’m also worried it could be structural damage or hidden plumbing issues, especially as the house is around sixty years old. I’m not sure how serious it is, which trade to contact, or if I should involve insurance. Feeling quite anxious and would really appreciate any guidance.

Hi. The floorboards are nailed down. Over time, the nails work loose, causing slight movement, hence the squeeking. As it is all over, one can safely rule out water damage.
The remedy would be screwing or nailing the boards down.

Hi there, thank you for sharing the details — it's completely understandable to feel anxious when something changes in your home, especially when it involves structural concerns. Here's a breakdown of what might be happening and how to proceed:

What Could Be Causing the Creaky and Bouncy Floors?
Subfloor Loosening or Wear
Over time, floorboards or subfloor panels (like chipboard or plywood) can loosen from their joists, especially in older homes. This can result in creaking and a "bouncy" sensation underfoot.

Joist Movement or Deterioration
Joists may shift, settle, or deteriorate — especially if they're original (60 years old). Inadequate support or even slight moisture damage can contribute.

Effect of Recent Carpet Work
Removing heavy wooden threshold bars and replacing them with lighter metal ones may not directly cause structural issues, but if floors or underlays were lifted and not resecured properly, it might explain some of the new movement.

Plumbing or Water Damage (Hidden)
Undetected leaks (e.g. from radiators, baths, or pipes) can cause timber to swell, rot, or lose integrity — contributing to soft or spongy floors.

Who Should You Contact?
Primary Recommendation: A Qualified Joiner or Flooring Specialist

They can assess whether floorboards or subfloors are the issue.

They can also check how well the new carpet was installed and if the bounce relates to the underlay.

If Joists or Structural Issues Are Suspected: A Structural Surveyor

Particularly if the bounce is significant or feels unsafe.

They can assess load-bearing elements and advise if there's movement.

If You Suspect Plumbing or Moisture Damage: A Plumber or Leak Detection Specialist

Look for signs like warping, stains, or damp smells first.
 Should You Involve Your Insurance?
Only after you have:

A clear diagnosis that it’s due to a covered event (like a leak or structural movement).

Documentation (e.g. a written report or photos from a professional).

Otherwise, insurers may not accept the claim or could log it against your policy unnecessarily.

Next Steps
Document where and when you feel the bounce/creaks. This helps pinpoint the issue.

Book a reputable joiner or flooring professional to inspect the subfloor and floorboards.

Request a basic written report or findings — this will help if further action is needed (e.g. surveyor or insurance).
Hope this will help.
