joists

Hello, have to repair an undersized and badly notched joist 38x175mm sitting in an intermediate floor connected to the ceiling below. The joist is sagging but also has a slope resulting in a lower level support in the middle of the flat (double span joists). A metal plate 8x150mm would be...

Hi, So I have an extremely noisey neighbour above me and I cant afford to move so my only solution install a false ceiling with "sound" insulation. I have total of 175mm clearance to work with and my plan is to afix battens around the walls with coach bolts and then screw 45mm x 120mm joists...

Hi all, been busy building a decking and I received all the materials for the frame four weeks ago. The joists have been stored outside on their sides on some brick footers. Made some progress at the beginning then had to stand still for a while; thus out of the ten 4.8metres 120*47 joists I...

Hi, New member with an odd query. I am having to do my own loft insulation in my apartment building on the top floor. (*I have permission from building owner). The professionals won't do it because they cannot install a hatch in between the joists (too small), and the only access point is...

Looking to re carpet one of our bedrooms, which has a pronounced ridge running the length of it, around 2ft from the nearest wall. Seems this is because the breeze block wall of the room below is higher (especially with joist hangers) than the joists that the chipboard rests on either side...

Hi Guys, I am about to put in my insulation between the rafters after my electrics first fix, The question being do I put the insulation in so they are flush to the bottom of the rafters or can I put them above my wiring as long as I leave my 50mm air ventilation gap? There will be 50mm pir...

Would timber plugs sealed in with resin be a suitable repair for this joist? We could thread the cable through just one hole ...the remaining four would be redundant. Replacing it would be quite complex so we would like to avoid that.

I've discovered a pretty severe woodworm problem when I went to fit a new carpet in the bedroom upstairs. It appears two of the joists have born the brunt of it and I think they need replacing. I'm going to attempt it myself as well because I'm struggling to get hold of a joiner due to them...

Hello everyone, I have spent the last few days reading lots of posts on constructional hearths for solid fuel stoves but very little reference to gas fires. The background: I have bought an 1890's victorian semi which was unoccupied for 16 months and previously rented out. The property...

Hi. I have just purchased a terraced house. Built circa 1890. It's in a row of 24 houses built on a relatively steep hill. The houses are built in pairs. Each pair is lower than the pair before as they step down the hill. I'm near the bottom. I'm situated so that, looking at the house, the house...

Hello, apologies if this question is asked a lot, but I find mixed answers in my searches. I want to board the loft of my 1870-ish mid-terrace house for storage, not a living space, but I also don't want to worry about the weight of the things I'm storing so might want to strengthen my joists...

Hi, first post here. We bought a home just two weeks before the pandemic kicked off... about 2 months later we noticed the living room floor can wobble. We viewed the house three times and visited for measurements many times after, we didn’t notice the floor shift once! There was nothing in the...

Hi, Would anyone be able to point me to the relevant building code documents where it details the fixings required to join to joists together to make 1 longer joist. It's my understanding that bolts are required in this situation but after googling I can't find the building code where this is...

I’m about to sister joists onto existing ones to level a suspended floor. BCO mentioned I could use screws instead of carriage bolts, but I didn’t quiz him any further at the time. Does anyone have experience in doing this, and would these do the job...

Our Victorian property has a flat roof side extension for the kitchen. The kitchen ceiling is in part under the original property and in part under the flat roof. A long RSJ props up the original wall of the house. We are going to fit a ceiling extractor above a new kitchen island. The...

Hi, I'm currently doing some work on the front garden to take the ground level below Dpc level and have removed paving slabs from the whole area. However after removing the ones in front of the front door, it's exposed the sub floor beneath the hallway. There's no outer brick skin present just...

Hi All I'm currently having the existing basement of my Edwardian semi-detached property made more 'user friendly' via the installation of a proprietary (Triton) cavity drain system, plaster board/plaster walls & ceilings & a wooden floor. One of the main tasks is to 'hide' the myriad of...

Hi, Starting to build a man cave in the garden tomorrow... Could you please help me verify joists of 47x220 C24 are ok for a span of 5.65m? As far as I've found, some tables say it's ok and some say it's not. I'm also doing 2 skylights of 90x120 and doubling up the joists around them, so I...
