I'm about to replace my stair carpet so I thought now is a good time to repair the last 13 years of abuse by children jumping up & down the stairs rather than walking(yes I'm a grumpy old man).
There not gone, just creaking & a bit loose, my thoughts were to just re nail them down & maybe get a vat of wood glue to put between each plank.
Is there a better way, or is replacement a better option?
Many thanks in advance.
