Nae, I might look into that. A sparky would approve wiring because it's only 3 months old. Had whole house rewired prior to moving in. the floorboards have gaps alright, they're OLD jarrah so gaps about 5 mm wide. you can see the tongue of the floorboards. i might try the talc in extra noisy areas I think. there are a few worse then others. Poor DP was commando crawling under the house yesterday to check the stumps under DD's room and he said wasn't nice!
