joists

Hi All I am looking to cover an existing external balcony (currently no slope) with hollow composite decking boards. I want it to be slightly sloped to allow rainwater runoff. My question is can you get shallow angled joists (that have a triangular side profile) and which the decking boards...

Hi all, I've just stumbled across this forum and am hoping someone will be able to shed light on the issue in my home. Whilst buying my house, we noticed the floors seemed uneven. I paid for a full structural report via the bank and asked specifically for this to be inspected. When I called...

After we had a leak from out flat roof I took down the plasterboard only to find that the joists are resting on a ledgerboard/wall plate instead of either resting inside the bricks or on the ledgerboard with joist hangers. I don't know why the previous builders did this when they could have...

The 3 pitch pine joists shown are cross section 9.5" x 2.25". Supporting pitch pine beam is under joists as shown in picture below. Beam is getting moved from under joists to end of the joists. Plan to use joist hangers to connect joists to beam. Anyone recommend correct good structural hanger...

Looking for some advice please. I need to remove a section of joist that is sitting on the padstone of a newly built structural wall in order to fit a steel post. The issue I have is copper pipes that would prevent 4x2 or 6x2 noggins connecting joists either side of the joist to be cut away. The...

As part of an extension I'm converting a car port to a room, the old car port has another room above it. Would I plasterboard (insulated type for heat retention/sound proofing)) the ceiling before I do the walls? Do the recessed edges that take the joint tape/mesh run parallel to the ceiling...

I'm in the process of re-roofing my flat roof and was thinking about the possibility of using it as a roof terrace in the future. I've stripped the roof and the current joists are 2 X 6 inches and are 2.45 m in length. The spacing of each joist is 20 inches. Would sistering with the same...

Hi all, I’ll try to explain the situation. I have a rectangular ground floor room which currently has the joists above it for the first floor removed. I need to add in an internal staircase and so I am in the process of working out how best to construct a wall to section off the stairs and...

In my living room there is a sort of brick wall running lengthwise which supports the floor joists running across the room. Is there a name for that 'wall?'

Unfortunately we are already amidst our renovation job, which includes also the redoing of a flat roof and upgrading it to a warm roof and I have a question regarding the insulation of the fascia, I find shocking that there isn't really much material on the web about it! The new joists have been...

So after a long weekend of removing my chimney from the attic and 1st floor I’m stuck! It looks like the 1st floor joists are sitting on timbers that are resting on the chimney. Whats the best way to tackle this? This is a bedroom that is going to be repurposed into a bathroom. Structural...

Hi All, I am currently re-boarding my loft after lifting old chipboard to put down insulation. I am using 22mm P5 T&G Caberfloor boards. 2400mm x 600mm. The floor was previously strengthened and levelled by running 3x2 joists at right angles across the top of the existing 4x2 joists. The...

Hi all, first post but I think I'm going to end up a regular here! I've recently moved into a house that needs plenty doing, and one of the first bits is to sort the loft out. I've attached some pictures, I hope. My questions are: I seem to have some kind of metallic cradle between the...

I installed a loft hatch today, and in the process found that the joists on either side are at different heights, an entire inch apart! I'm looking to board out the loft in the new year, with 2x4's across the existing joists and insulate and all that good stuff, but now I've to work out how to...

Hi all I have a garage with flat roof neglected for years hence the joists are rotting away, I need to replace them but only problem is these joists are 5.3 metres long! I've not seen any timber this long anywhere, longest is 4.2 metres so I was wondering is it possible to join two 3 metre...

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...

Basically I wonder if anybody could give me any tips on making my loft space into a nice clean usable area. First of all I am not putting in any stairs I am still going to be using the existing loft ladder the space up in the loft is very large indeed I was hoping it would be okay to keep the...

Hi, going nuts here a bit. I'm trying to do the dims for my garden office and am doing 5x2 roof joists with firring strips on top for the pitch. I am doing 400mm centres, but this does not seem to work to get the end of the OSB (1220x2440) to end on half the joist. I've read somewhere you do...

Hi, I would like to lay a new floor covering in the first floor bedroom in our victorian terrace. The problem is that the 5x2 floor joists (actual size 120mm x 60mm) are at 800mm centres with no noggins and span roughly 2.4m. Ideally I would make the structure better in order to accommodate...
