Wooden Floorboard project

[dojo]

Just found under the grotty carpet in the front room there look to be some very dirty but potentially nice floorboards.

The idea would be sand back, put pine slivers in the gaps and then varnish.

One corner has dropped away so need to lift those boards to look at joists underneath.

Obviously I'm keen to reduce heating bills as much as possible but on the other hand I don't want to create a shed load of extra work and expense!

Question is will the slivers do the job keeping the heat in or will there be a massive difference if I lift all the boards and put down some insulation materials??

Think its going to be the former, but no pointing in half doing a job... just makes it quite a lot more of an ordeal (and a lot more earache!!!)

Hi Paul,

Thanks for the reply. I was under the impression you could buy wedge shaped bits of pine and drive them down into the gaps, let them set, chisel off the excess and sand down when you do the floor? I will happily (well not happily) lift all the boards if needed but if difference is marginal I might not bother

I know its sales blurb but this is what i was looking at.

Thanks for the answers guys, I'll drop you line Alex if I go down the mass fill route. Think I'm going to start off by repairing the dropped corner and giving it a provisional sand to get an idea, then decide whether to go the whole hog or re carpet...

It looks as if I am going to have to take a chunk of the boards up to fix some of the joists...
Therefore going to go whole hog and celotex insulation under the boards... Does anyone have any recommendations as to the best or which celotex thickness I should use??
Thanks

Started this a couple of days ago, had to rebuild the footings, all celotex is down and boards back in situ... In the middle of nailing boards back down which is a killer! Hey ho. Sander is hired and all going well should be up and running tomorrow.

Can I ask OP why the insulation doesn't come to the top of the joists and hit the underside of the boards, or is there another layer of insulation/UFH to go in I'm not seeing?

I left a little gap cause 1.it was easier to put a batton underneath the joists to support the celotex and 2. I'd there were any small gaps gown the side of the celotex I could fill with expanding foam. The whole thing is draft proof and there is enough room underneath for ventilation via the airbricks so should be good.

I've just sanded back the boards and half the room (extension - newer) seems to have used treated wood, or at least had it treated, it now has a green tinge to it, I've worked it pretty hard with the sander but it's still there, I applied a bit of danish oil but the green still shows through...
Any suggestions??
Thanks

• edit

I think the green tinge may have been woodworm treatment.
I'm using a medium I oak coloured oil, would a darker oil mask the green better?
