Hi,

This weekend I'm fitting some solid wood flooring on to existing floorboards
in my downstairs corridor. The existing floorboards are the same age as the
house (100 years), 160mm wide, tongue and groove fit, on the ground floor,
on joists, above an open basement.

The new floor consists of 18mm thick, 85mm wide pieces of varnished oak, in
a few different lengths. It too is a tongue and groove fit.

According to the instructions for the new wood floor, it's OK to fit these
directly on top of the existing floorboards (without an underlay) using a
secret nailer as the sole fixing, under these circumstances.

The existing floorboards are sound - they don't creak, they don't move and
they are level. My only concern is that they run in the same direction as I
wish to lay the new wooden floor strips (along the length of the corridor).

I'm assuming that, what with both the existing floorboards and the new floor
being tongue & groove, and using the secret nail fitting, I will get away
without having to insert an extra layer of boarding. I want to avoid this as
I'm already pushing my luck with the extra height of the new floor.

Does my logic seem reasonable or am I going to get in to trouble?

My plan is:
1) Peel up old lino currently covering the floorboards.
2) Remove old skirting board and door frames & architraves on all sides
3) Ensure floor surface is even and no nails/screws sticking out
4) Route telephone & CAT6 cables into a channel in the wall, behind skirting
board
5) Lay new floor edge to edge
6) Refit new skirting, door frames & architraves on top of new floor.

Is there anything else I need to look out for?

As always, thanks in advance for your advice.
