I have inherited a deck - not sure of the boards but think they are cheap softwood things (with the ridges upwards) and are nailed into pine joists.
The nails used are now lifting all over the place - and don't look like deck ones.
Looking at various threads I want to go for some deck screws to really hold the boards down. However can I get away with 1 screw, put in between each set of nails and just leave the nails there or do I need to remove the nails and replace with 2 screws at each fixing point?
All advice gratefully received
Thanks
David
