yep sorry i mean 1) put the floors down 2) electric and plumb first fix 3) insulate and board from underneath. At the moment in the loft and first floor, it is just bare joists and i've put a few plyboard sheets down so we can walk there; electrics and plumbing will be done in one hit, but is...

Hi, I'm in the middle of renovating my property it's got three levels; ground floor, first floor and then loft conversion on the top. I'm at the stage where the building is water tight and I've got all the partitions up on the three floors. I am thinking to put the floors in next - Tounge...

Hi, I will be having a small flatroof to the side of the house (2m x 2m). Wanted to check if I need to put the Masonry Joist Hangers directly into the existing Brick Wall? Or if I can put a timber wall plate and then timber joist hangers go into the wall plate similar to attached (I have...

Hi, I've just poured the concrete slab floor base in my ground floor. I'll be putting 100mm insulation + UFH pipes + 75mm Screed on top of this. There are a number of internal timber stud-partitions that I need to put up on the ground floor - Do i need to put these up before the...

Hi - did you mean Screeding in between the joists? one of them did list that, but they said you need to check if the joists would be able to cope with the extra weight of the screed, which I'm not too sure how to check; so not sure if i will go down that route.

Ok cool - I'll take a look at that, thanks. did you still need to put insulation in between the joists though i take it?

Hi yep I have reached out to a few. They all say that eng wood is fine, just that it takes longer to heat up, but then will retain the heat longer once it is warmed up. There's two options for the timber floor from what i can tell - either insulation + spreader plate + pipe or foil-backed...

Hi, We are renovating our house - its currently been gutted and we are thinking of putting Wet Underfloor heating in the whole house and currently weighing up the options. The ground floor will definitely be UFH (concrete floor so will be 100mm celotex + pipes + screed + flooring.) and we are...

Thanks all - apologies for my late reply I'll take a look at the heat pump option - any recommendations for manufacturers / suppliers of this? Someone was suggesting to go for one of those combined A/C - Heating units - has anyone had any experience with those?

Hi, I wanted to check what are the options for heating / hot water without using a Gas boiler. I've spoken to a few people who have mentioned a few different options: 1. Electric Boiler which can then be connected to traditional radiators 2. Electric Radiators 3. Immersion Tank Just trying to...

OK - thanks. What is wrong with the crushed concrete? It is a lot cheaper (at least a few hundred pounds) than the MOT Type 1 so just want to check what the pros / cons are of each. One of the companies I was looking at specifies this - MOT Type 1 Crushed concrete is literally crushed...

Hi, Had a couple of questions on building the concrete floor base for my extension to my house. we have already built up to DPC level brickwork now so next going to add and compress hardcore and sand then pour concrete slab. 1) 150mm Hardcore - what is the difference between Loose Type1...

Hi, For an outbuilding, we have 9inch (220mm) roof joists and 4in (100mm) insulation and 18mm OSB3 boards for a warm flat roof. Based on this I think I will need at least 340mm Fascia boards - but I can't seem to find any; most seem to go up to 225mm only.. I was planning on using 18m fascia...

Ah Ok cool - I already have a Mortar Plasticiser - Sealocrete Sealomix so that sould be fine? I'll need to check with him about why same mix for both leafs - i didn't think it made it a difference? and also i'll need to check about below dpc vs above dpc..

Hi, Architect has specified that full fill cavity walls should be built with 1:1:6 cement mortar; just wanted to confirm what that means? is that 1 Lime : 1 Cement : 6 Sand? I will be planning on using BlueCircle Mastercrete Cement - do I still need to get the lime added? Is there any...

Do the new airbricks in the new extension need to be below or above the DPC Layer? or does it not matter?

Cool - thanks all.

Hi, I've got the roof joists in place now for my out-building and just wanted to check next step for fitting the Fascia Boards. Am planning on putting 100m celotex / kingspan ontop of the joists, then OSB3 boards on top of the insulation then finish it with either fibreglass or rubber roof. I...

Would this be correct then?
