Hi I'm looking to put a joist underneath some flat roof joists to give additional span support, but I don't know what type of hangers would be suitable, especially on the wall where the ends of the timberwork are shown (this is the end of another joist on the other side of the wall doing the...

Hi I'm fitting some insulation and new PB to the window reveals but am concerned that it's going to finish far too close to the window beadings which could make a broken pane replacement very difficult. I've currently put 25mm insulation up there dry-fit to test and by the time 12.5mm PB goes on...

Hi I believe I need to put a vapour barrier above/within a small suspended ceiling I've made. The area will be used for kitchen things and I'm expecting I need to protect the main roof joists above from the condensation of cooking etc. Trying to thread in a plastic membrane is going to be...

Hi I need to connect an oven and hob, I've looked at the regs and calculations etc and can't see anything I'm missing or wrong, but if someone's kind enough could I get a second opinion please? Oven is 5.9Kw / 25A Hob is 7.4Kw / 32A Cable is 6mm T&E (clipped direct) which should allow max of...

Hi I’m rebuilding my kitchen and have to insulate the outer brick walls so I’ve put up stud walls with celotex between the stud timberwork. But I’m undecided what to put over the studwork on the inside face. OK so it doesn’t need to look pretty beneath the kitchen base units, but I’d rather not...

Hi I'm planning to install MDF cladding internally on a new vaulted ceiling. Buildings regs have just come back to me and said the following - The ceiling of your residential extension should be protected to resist the spread of flame over its surface according to classification C-s3, d2...

Hi I'm always confused by vapour barriers.... I have a kitchen with a flat roof (warm deck as it's insulated above), and an adjoining blockwork wall. The roof joists are currently exposed, and the internal wall will be battened up the blockwork and PB on top (no insulation) as it's a very...

Hi I'm just building a frame to make a floor level - because the original house floors drop away quite significantly. I've laser mapped the floor and cut the fillets to measure, the end nearest the door skims down to a few mm and then on to latex, whereas the far end has raised about 7" (it's...

Hi Yesterday we had a brief power cut for a few seconds. Apart from finding I was now the lucky owner of two dead computer monitors, on inspection of everything else I see that the Hager SPD's in my CU are showing red on the indicator panels. Hager say they are "end of life" - so does that mean...

As the question, every time I buy something from Screwfix I get the emails asking for product reviews with a £250 tempter, but I don't know of anyone who has ever received anything. Have any of you been lucky? I don't mind leaving product reviews if it helps someone else out, I kind of dislike...

Hi In a small block of flats our tenants need the teleswitch and meter replacing as they're on storage heaters and the teleswitch service will be discontinued soon, so their only option would seem to be a smart meter to replace both items. I would have preferred them to get a dual tariff...

Hi Random question not entirely DIY but of course something many of us encounter..... I'm getting a 100Kg glulam delivered (5M long) and was wondering how to get it off the lorry. Cost is an extra £150 quid if they send a hiab (probably +vat too!). Does anyone think it's easy enough to slide off...

Question is how much usage do people make on average out of the offcuts of plasterboard? Joints would be over the same timbers, scrim taped (50mm) and Toupret joint filler compacted in. Ideally I'd finish this with full boards, but I've run out of full boards and got lots of decent sized...

Hi I've got a stub of a wall to remove tee'd off from another wall which I believe is made in 7N concrete blocks. Ideally a 9" grinder would do it but I'm not comfortable using one above my head or while on a ladder - plus the insane amount of dust a grinder would generate is an issue. I don't...

Hi I've got a newly laid concrete subfloor that's pretty well flat and at the right height to follow on with engineered flooring (with 3mm foil underlay) - I won't need to be building it up with latex or anything. The slab is entirely tanked in with 1200g sheeting and therefore unlikely to be...

Hi I'm just letting people know that Screwfix have changed their login password requirements to be passwords between 13-20 characters long. I found I couldn't log in on any of my devices last night - and I had no prior warning of this change either so I obviously thought my account was hacked...

Hi, There is a large timber beam spanning two rooms in my house, which appears to be decorative and not structural. However it's a bit of a monster (about 28 feet long and measures around 9" x 8"), and I really wanted to look for second opinions before I tackle removing it, especially as someone...

Hi, I wondered if something like a 15mA SRCD is available? I have a socket near my front door which would be useful for external things like jetwashers but I want to avoid tripping my house ring (which is on a 30mA RCD) and to help give discrimination on the circuit. I appreciate that the main...

Hi I want a z-wave device to measure the temperature of my hot water tank so I can control the boiler (it has a Fibaro switch). Ideally a sensor unit with a probe I can insert into the tank's sensor pockets rather than tear a gash out of the jacket for a surface mounted one (i.e. Secure SES002)...

Hi I’ve not used OB1 adhesive/sealant before and wondered if it’s suitable for sealing the gap between the shower tray and plastic wall panels? I’m not sure how it finishes off when cured and if it’s any better than silicone? There’s a small amount of movement on the wall boards (which I can’t...
