    Wooden shed condensation

    i'd also go with more damp air is rising through your floor from the slab than the ventilation can cope with. the under floor air gap/ventilation is needed so the damp air is blown away instead of entering... wrong time of the year for it, but i'd suggest.... empty the shed. get a...

    Where is my void then?

    Never did finish this job off. Over a year gone past now :( Classic case of the floor went back down, the room back into use and never got opportunity or motivation to restart. Did solve my battery problem. Got a fancy new and much better bosch drill/driver again with two batteries. £90...

    sheet metal/box profile shed roof - condensation/frost

    Hi. Building a big shed (storage/workshop) at 24x10 and decided to put a box profile roof (hopefully last nearly forever!) on it. Dithered about putting the cheap and nasty supplied felt on as a drip catcher. Initially decided not as i didn't think i'd have a condensation issue due to no...

    Carpet not gripping at all (felt-backed...)

    Is the underlay much thicker than gripper, so lifting the carpet backing off the gripper? Are the gripper spikes all laying flat, so not digging into the felt backing? Pushed down from the last carpet that was on them? creases and folds sounds like either a lot of slack in the carpet that...

    It was a pegler valve. Anyway, another bought, shaped using heat this time, combined with a oval shaped float meaning less of a bend needed. All good. thanks all for advice offered. Merry Christmas

    Cracked my float valve arm - what to do

    I've cracked the float valve arm while shaping it. Do I need to replace it or can I leave as is? The story... Had a leaking coupling between feed pipe and plastic/nylon float valve fitting in the toilet. After much faffing about I couldn't get the leak to stop, (lots of different fibre...

    PIR boards - how rigid?

    my flat roof was converted from a cold roof to a warm roof. it now has 125mm PIR on it (can't remember the make, but not celotex). the PIR had a 9mm plywood layer fixed to it. Can walk around up there without any hint of give under foot. Does have 3 layers of felt on top of the ply, plus the...

    Mice

    mice can also squeeze through tiny holes, seemingly much smaller than the mouse. so you might be looking for something the size of about a 20p iirc...

    Where is my void then?

    all been worthwhile, found some money under the floor... a 1p, from 1917. new problem... 21) a short span of wall with dubious support. there is the foundation, some loose rubble and then a floor slab for my kitchen with the wall sitting on top of that. removed an old bit of hardboard...

    underfloor insulation

    is it just me, or is one of those piers/pillars leaning? do the pipes need insulating while you're on? what are they pipes for?

    Where is my void then?

    sure I've heard the freezing battery one before somewhere. the second... interesting. though think I'll stick to trying to kill myself doing the floor. planning on screwing all the boards back down, so see how that goes wrt battery life. cordless is a Bosch PSR18. done well for what I've...

    Where is my void then?

    tony, thought I'd put it all down for the benefit of others/see if anything was more significant than I'd appreciated, and me this time next year when motivation says do the last bedroom or hallway. remind myself what a right pita these jobs turn into...

    Where is my void then?

    they are NiCD. part number 2607335277. a very quick google search shows 40-50 quid per battery. got the drill, two batteries and a charger for 50 quid! Probs a better deal to get a new one.

    Where is my void then?

    Thanks for the reply Pinenot. that adds weight to the leave it well alone and "if it ain't broke" argument... The foundation on the 1960s extension is about <drum roll> 6 inches! Found that out today while following a bit of old lead pipe. pretty sure that is why the joist was notched...

    Where is my void then?

    Progressing a project to generally improve the floor in the lounge/diner. Found loads of problems, but one I thought I'd seek some advice over. as I've written loads, I thought I'd best come back to the top and write a little summary... the ventilation void under a chipboard floor is tiny...

    Compression Joints

    don't over tighten your compression joint. that'll make it leak too. i always coat the inside of mine with boss green jointing compound.
