When I moved into my house I received a Rentakill certificate to say
that some work had been carried out on some of the floors to treat
against wood boring insects (this was in 1998).
I'm about to lay a tongue+groove solid oak floor on top of the original
flooring and wondered whether it was worth updating the treatment on
Is this an easy DIY job. Can you just treat the top surface or do you
have to start pulling up floorboards? Presumably rentakill have a
special magic way of doing it without resorting to mass floorboard
Has anybody else bothered to treat a subfloor like this before laying a
new floor on top?
