amavadia Posted September 18, 2018 Share Posted September 18, 2018 I have large chipboard floorboards in the upstairs of my house which I need to lift to do some piping and wiring. They are quite old so come up easily however, they don't stop at the stud walls but actually go under them. Im clearly going to have to cut the boards along the edge of the walls. My question is how do people do this? If I cut them along the walls, there won't be any support for those edges when I put them back on? Any advice much appreciated.

ProDave Posted September 18, 2018 Share Posted September 18, 2018 Cut along the edge, or better just a bit away from it with a multi tool. Also use that to cut along the joint to cut the tongue where you want to lift them. I have an old slide hammer nail; puller that helps to take boards up relatively clean. Fix a batten behind the cut to support the free cut end. Watch out for pipes and cables touching the underside of the board. Most of us in the trade will have had "the fountain" at least once.

Onoff Posted September 18, 2018 Share Posted September 18, 2018 Is a Cavity Master type kit any good? A few different makes around. Sure mine is 127mm not 100mm... 1 Link to comment Share on other sites More sharing options...

Luckily its not tongue and groove. Just big sheets of chipboard. Ive pulled one end of one board up just using a utility bar and bits of wood to lever it up one nail at a time.
