we ride at dawn Member 4363, 1442 posts SQ 310, BP 250, DL 320880.0 kgs @ 104kgs UnEq | Does anyone know about joists, I noticed some of my chipboard has a bit of movement so I slid my phone down to get a photo to see the cause (and it literally is just sitting a cm above the joists), but was a bit concerned about the joists themselves, they have a very odd colour to them, despite no visible degredation and feel ok if prodded with a knife (no crumbling or softness). Don't suppose I can send the picture to anyone who knows what they are actually looking at? The house was build late 1800s just for context. | ||

Can also be twisted and warped downwards (with weight) as they didn't pressure treat wood to harden it (tanalise.) They are rough hewn not smooth like modern lumber. If you couldn't see it it's usually like they had a competition to see how s**tty a beam they could get in. See photo: www.encorereclamation.co.uk/wp-content/uploads/2016/04/recl... | ||

This is a screenshot from a video I took from dangling my phone down the tiny gap behind the skirting board; didn't fancy trashing the floor. The edge I could access I gace it a good stabbing with a screwdriver and it just 'knocked' like solid wood. It's almost like there's a layer of something crumbling; I've seen dry rot before and it doesn't look like this so wondering if there's been some treatment in the past that's corroded giving the weird texture. Be good to get your thoughts, if it's something that needs resolving I'd rather voluntarily do it before I'm forced to... https://i.ibb.co/19j2s9d/Screenshot-20210410-100429-2.jpg Really appreciate this. Things like this legit triggers my anxiety haha Also for scale, the joists are as wide as my palm and about 10 inch tall, spaced at aabout 12 inch apart. | ||

 old age traveller Member 332, 7866 posts | Ground floor? From the pic it looks like the timbers may have been painted with something which may now be falling off. Any aroma? I would cut out a bit of the chipboard for a better inspection. Do the cut over the centre of 2 joists to make the "rebuild" easier. Just remember asbestos was not banned until 1999!!!!!!!!! I have a theory that if your house is over 100years old and has not fallen down yet it is unlikely to do so. | ||

Battle I have is there's laminate flooring over the chipboard which means I can only work backward from an edge to get it up. From the bit I can get to, I've stabbed with a screw driver and it literally knocks as if hitting new timber. I can't push the screwdriver through it and can't get anything to crumble off...which I'm guessing is a good sign. No aroma. Other than the colour (which is what prompted the post), it seems fine. Obviously reading horror stories of white rot etc, and flapped a bit. I can't find anything that resembles it so I'm wondering if it is some coating/treatment that's made it look this way and nothing to worry about. | ||

 Has little understanding of the sugden Member 677, 11338 posts SQ 165, BP 125, DL 220510.0 kgs @ 80kgs UnEq | Post Edited: 10.04.2021 @ 15:52 PM by PeteHodgson Kinda looks like it has been burned/scorched. I burning is a treatment used for weatherproofing timber sometimes, but probably not for internal structures. So...I’m out. Sorry.Edit: if it was this, there’d be charcoal on your tool! Pardon!! Don’t be as strong, problem solved. | ||
