I note that some contents insurers will only cover:
floating wooden floors paid for by you after the building was built
While other contents insurers will cover floating floors regardless.
I’ve tried claiming floating floor damage from the OC building insurance. They have referred me back to the contents insurer. CHU (considered to be a market leader) for example specifically exclude floating floors in their strata building insurance:
Building means:
…
fixtures and structural improvements other than Floating Floors;
But include them in their strata lot owner contents insurance.
I hope you are not caught by a cover gap between the OC’s building insurer and your contents insurer!
