Floorboards too thin

Anonymous user 03/03/2024 - 3.37 PM

I have bought a 1960's house and doing some refurbishment works. The first floor had carpet flooring which will be replaced with laminate. Under the carpets are planks 170 wide by 15mm thick (!?) Joists are spaced at about 300-350mm. The floor is not moving or bouncing (at least not that i can tell). I will be securing the planks with bolts on the joists (currently on nails). A couple of planks have to be replaced as they are damaged (split along the length) and I expect some more to be damaged while securing them as bolts slice open the planks. Do I replace them with a similar 15mm thick piece planks, or since I have done all the hard job so far, replace the 15mm planks with 18mm sheets to be totally flat and rigid?

Are you a tradesperson and able to answer this question?

It's entirely up to you. If the floor is sound and not moving, putting planks back is fine. Pre-drill the planks to stop them splitting.

Structurally it should be fine .joists are closer than normal so that's good .it depends on whats more cost affected to replace all the boards or a few .a few should be fine you could go over the floor with some thin ply this would leave you a nice flat surface.hope this has been some help

Not sure why you would want to use bolts on floor boards! As long as you use flooring nails the boards would be secure. If you need an access board I would just use a hinge on the one required
