Agreed mate, but if I scan it and miss a nail i will be paying for new blades on his machine, whereas if he misses a nail its on his dime. Will let you know how this plan goes...If you buy a good quality handheld metal/pipe/wire detectors you can save yourself the cost of having someone do it - but thats me, I'm so tight I squeek when I walk.
Howdens delivered Kitchen, Utility and Butlers Pantry components today so the lads will be busy next couple of days. Missus went for Miami White Quartz worktops which are out sourced to a separate firm to fit. Cheers
