joists

Just had an oil to gas conversion done. The company who carried out the work notched my 100mm loft joists pretty badly in this location of my loft, as you can see in the photo. I have raised this with them and they are getting in touch with a joiner in order to put all this right. Question -...

So on Friday I had my loft insulated, a difficult job as we have some suspended ceilings which have been installed over old lathe and plaster vaulted ceilings so access is extremely difficult. As they were leaving after successfully completing the job (adding 300mm of Knauf loft roll) I asked...

Hi all, I bought a home that has had a double storey side extension done. Upstairs where the extension meets the rest of the house, there is a drop in floor height. The old owner tried to prop it up using insulation boards, but with laminate flooring installed on top of that, it's started to...

Sorry if this is a very obvious answer however I cannot find it in the archives or on Google. When fitting timber joists to steel. If I opt to notch the timber into the beam what stops it from falling out. On all the guides I’ve seen they are just plonked in the web with noggins and wall ties...

We have a flat roof on our ground floor which acts as a large bay area to our living and kitchen area. It's approximately 5 meters by 2.5 meters. We have an issue in that the builder (who has since done a runner but that's another story) mis measured our steel and had to fit new steels after...

Hey all Long story short. I've pulled up my kitchen floor and found most of it in reasonable shape except for this cross beam which is badly rotten. It was encased in damp dirt which explains things. The property was built in 1900 so perhaps this is inevitable. There is a copper gas pipe...

Our floor is a bit bouncy. I went into the crawl space and videod the problem. It seems like the joists are not sitting on the foundation properly and are springing. What would be the best way to fix this? Many thanks all

Hi, We took up the flooring on a house we've recently moved into (5 different layers of laminate and lino!) to find the floorboards and joists pretty rotten in places. We're going to replace all the joists and wall plates on top of the sleeper walls, but try and keep as many of the old...

Hi all Hope you're well. I've just had my house re-roofed (new membrane, new battens , new thin edge sandtoft concrete tiles, and new dry ridge system). Following rain, the wooden rafters are getting damp in some areas (always the same recurring spots). When the rain stops and we have a dry...

Im about to overboard with insulated plasterboard an existing top floor lath and plaster ceiling. I just popped up the loft to check out the joists and mark up where the joists sit so that I can be sure to fix directly into them ... But we've got a problem... You will see from the photo that...

Hi guys, I looked at a house today, it has a great layout and great potential for a really nice home for myself. However, there are some exposed woodwork that doesn’t look good to me. What are your opinions please?

Hello all, so I’m building a small 2.4x2.4 deck this weekend, I’m having a debate with my self about joist sizes. Wickes have got an offer on at the minute so 3x2 (70x45mm) is currently £4.50 per 2.4 length. Would this be strong enough for a low level deck? I’m planning on spacing joists at 30cm...

Hi, I noticed that one of my bathroom boosts has cracks running along it's length, is that normal? It has an area where it has rotted too, which I am planning to sister in that area. Thanks

hello all i want to board my loft. across it i have 4 binders (two middle 4x4 and two 4x2) on top of celling binders whith are 4x2 these binders are little in my way with boarding, so i was thinking to add another 4x2 joists on top of them (with will give me nice 300mm space for isulation) I...

Hey everyone, so a floor joist in my kitchen has rotted across most of it's length due to some prolonged water damage (now sorted). I'm going to replace the joist completely it was attached with a few big nails into masonary and had dropped, doesn't seem secure for a floor that sees heavy use in...

Hi all, So I have an not level ceiling so today I planned on removing it, sistering joists to straighten it up and then plasterboarding. The ceiling is lath and plaster that has since been over boarded, so a lot to come down. So here I was in the attic trying to kick the ceiling down and then...

Hi there. I am working on a 1930’s Edwardian terrace house. Dining room floor was in bad condition, the rear 75% of the floor was heavily damaged by woodworm – I could literally tear the boards up with my bare hands and they disintegrated – and the last 25% of the floor nearest the rear...

Hi all, Doing home renovation in my 1930's semi detached involving moving stairs so need to cut some joists and hoping for some advice. Please note I will be seeking services of a structural engineer closer to the time. Currently upstairs joists run left to right. I plan of fitting a double...

Hi Guys, I'm removing my planked floor and replacing it all with 18mm plywood. I'm then going to add decoupling membrane to tile over. I've come into a little snag where some of the floor joists don't go to the end of the room. Pic below: What is the best way of extending these to the edge...

Hi, I'm planning to rearrange the walls in my 2 bed semi to allow for another bedroom. To do this effectively I need to move a stud wall that runs across the roof joists, by about 300mm. I've been up in the loft and there's a joint in the roof joists that sits on the stud wall. When i move the...
