joist

Hi, I have started redo my bathroom and after removing units and tiles from the floor it had uncovered damaged pipe that was leaking slight moisture into the ply the tiles were lied on and underlying floorboards. The floorboard had dried, but still looked nasty, so I wanted to replace them...

Hello, I'll try to keep it brief: we are having a wood stove installed, and the HETAS approved installer has cut through a joist in the first floor, and a joist in the roof to allow the flue to run up and through the roof (it has an angle in to avoid rafter). There are now two joists (circa...

Hi Everyone I would like to remove a wall on the first floor. The house is a typical 1930s terraced house. Attached is the wall in question. The wall is a brick wall, but I have checked the loft and the joists are parallel to the wall except one joist that sits on it. However on top of the...

Hi, Has anyone ever come across this? I have what I originally thought was an old boiler flu. But it doesn’t go up to the ceiling above. Instead it appears to be support for the joist of the house. I’ve included two photos. The one with the brickwork is the top of the support / pillar where...

3 old pitch pine joist ends are partially worm eaten at the sides. It's not bad and appears to be shallow only. Easiest to do is double up and bolt ons without chopping off wormed ends. Then again worm may not be dead, though my feeling is it is. Can I somehow treat in place wormed ends in...

Hi all, I am looking to board up the loft to a good standard ("proper" and all). Everyone recommends - in order to hold the insulation to raise the floor before boarding. And the best way is to do this is to screw cross-battens into the ceiling joists - (2" by 4" timber battens have been...

Please can anyone give advice on this rsj installation. I think we might have issues with building control on this one. The joist hangers haven’t been put on correctly and have been cut off instead of bent over the top. Is this safe and will it pass building control inspection? Thanks

I'm weighing up a few options on fixings but any advice please on the following queries regarding a raised deck (about 900mm up) using 47 x 150 joists (2.5m long) and ledger (4.8m long) with posts at 1.3m: 1 How to attach the rim joists to the ends of the ledger board as I can't source...

I'm about to order the timber and fixings for a raised deck base (approx 900mm off ground) and wondered if anyone could confirm/comment on planned fixings as noted below please ? Raised deck 4.8m x 2.6m with ledger along one of the 4.8m sides Ledger 150 x 47 Rim 150 x 47 Joists 150 x 47 at...

We're just completing a new build extension and planning to build a deck out from it, ie 2.5m out by 5.0m across approx. Deck boards 5.0m to run perpendicular to building so joists 2.5m going out from building. There is a patio doors pvc sill below which there is a gap then the concrete sill -...

Hi, I'm tackling a loft conversion and hanging my joists fully below the support (152×152×30 UC) with Strong tie JHA450 hangers. Strong tie have confirmed this will still provide at least 4kn of strength. However I need to prevent the joists from swinging forward and aft as they are completely...

Hi, ever since we moved in to this house there's been a 'thump' noise every time we walk over a particular part of the (downstairs) living room floor, which is a standard floorboards over joists construction. I'd always assumed that this was due to a loose floorboard or two but since taking up...

Hi, I want to fit a curtain pole to the wall, above a pair of windows and door. The problem is there seems to be some sort of metal lintel about 1 inch below the plaster. I've bought the finest drill bits - Milwaukee Thunderweb, set my cordless drill to hammer and max torque and it won't go...

Another chapter in the House of Pain. Apparently I can't put my proposed 700 litre thermal store where I want to put it (ground floor to the right of the woodburner) cos there isn't enough rise for the thermionic syphon to behave properly. The thing will weigh about 850kg when full and is 600mm...

Eveining, I need to replace about 1m of joist in an alcove that has historic woodworm. It's 100mm x 50mm, or 4x2 in old money as the house is ~100 yrs old. Issue is the closest I can get is 95mm x 45mm finished. Can I cut a slither off the timber and use as packer underneath on its end? It...

Hi, I'm refurbing the galley kitchen in our Victorian terrace (solid brick walls, no cavity). Three of ceiling joists (which are the floor joists of the bathroom above) need replacing completely (they can't be sistered) but are pocketed into the brick walls on both sides. One of those walls is...

I need to add more attic storage space, so I want to put a floor down in an unfinished section of the attic. Joists are 2"x6" and 16" on center with 10" of blown insulation. My plan is to strap another 2"x6" perpendicular to the joists giving me 11" of space for the insulation, and then...

So we had central heating installed and were later told that the plumbers had cut through the joists when they shouldn't have- the floorboards were essentially resting on the pipes etc.... So then somebody came along and drilled holes through the joists under the cuts to feed the pipes through...

Hi all, not sure if I'm posting this in the right category... I want to add a small chandelier type light fitting to hang in the centre of the room. There has never been a light fitting there so there are no cables existing. It is a very old house with exposed wooden structural beams and...

I have concerns about all the holes that have been drilled into the joists in our new extension. My understanding from documents like this (North Herts Council Building Control Technical Guidance Note No. 22 Notching Of Joists) is that holes should be: Drilled into center line. Drilled between...
