Hi, I've been getting quotes for a replacement boiler. A Greenstar 4000 30Kw system boiler is £1600 from Screwfix. Add say £200 for a through the wall flue kit and plume diverter, and £50 for sundries - so £1850 for materials. I already have a clean system with Magnaclean and an old Greenstar...

I'm having an extension built where there was previously a brick bay. For whatever reason (I assume the builder didn't trust the foundation) he has used a floor beam as a lintel to span the bay and then rested the ends of the beam & block floor beams on it. So effectively I have a 175x75 beam...

Hi, what is the current requirement for RCD additional protection on a socket circuit? Is it for just the socket outlets or for the whole circuit? I have builders in, who keep tripping the RCD with their mixer, pump, breaker etc. I have given them a dedicated circuit on it's own RCBO which at...

Hi guys, a couple of first fix questions if I may? What do you do with accessory and socket wires? Tape in a circle and leave in roughly the right place? I have a mix of plasterboard and rendered walls so do you cut and fix back boxes in render as part of first fix (like chases) or as second...

Hi For those with experience of BG Fortress... In another post I've seen that my BG twin RCD box is no longer considered suitable as it uses type AC RCDs. The solar people also installed their circuit onto one of the RCD sections which is a bit naughty. The installation is TN-S if that makes...

I have several bricks to chop out and replace so was thinking of buying a tuck pointer. What size? 6mm or 8mm perhaps? I was thinking it should be slightly narrower than the joint so 8mm best but then Screwfix sell 6mm and 12mm. Is stainless worth the extra? Any other suggestions? Thanks

Hi I've done footings and bedding/haunching before but am going to cast my first surface exposed slab. Looking at YouTube videos they are all USA and seem to use a corner trowel to round off the edges...

Thoughts on Yorkshire boarding please? I'm building a garden store 6m x 1.2m pent roof. Divided in half. Each half will have a pair of gates. One half for a bin store and the other lockable for storing garden tools. My thought was that Yorkshire boarding will allow some ventilation to the bin...

Hi Is it possible to hide a forum from "new posts" and ideally completely? There is an option to do this for the combustion chamber but not others. I would like to come and learn about DIY and help others and the top posts always seem to be the general bigotry and trolling in General...

Hi I need to cut approx 12m of tarmac to pour a slab. A Stihl saw is £40 for a day's hire whereas a road saw is £60 and cuts deeper to 150mm. Seems a sensible idea and saves the old back. Any thoughts or tips? The saw is a "one side only" which means one way I'll have to push up hill for one...

Hi, can anyone identify this TRV and what size allen key it uses? A 2mm spins and a 2.5mm doesn't fit. The rad isn't working and I'm trying to find the blockage. Normally I'd start by checking the TRV pin but I can't get the head off. If I need to replace, any suggestions on a straight TRV...

Hello Telecom Premier Elite with a wireless bell. Batteries are around five years old so have had a good run! No low battery alarm but went straight to supervision fault and I suspect the batteries. I have 8xlithium AAs. As there is a supervision fault I can try the bell disable by pressing...

Hi I'm planning an extension. The living room will have a fireplace with balanced flue inset gas fire. Should I make the opening the standard 410x560 and is 250 enough depth? How does it need finishing eg bare block at the back and plasterboard or cement board to line the opening? Also how...

Hi I have some construction work starting soon. It's a bungalow with a flat roof bay. The front of the house is busy with guttering, lighting etc and I've identified the best mounting points for a dome CCTV camera as either: 1. On the bottom row of concrete roof tiles 2. On the lead flat roof...

I have started getting water hammer in the cold system. We've isolated the banging to a general area but can't find the specific location - it may be in a stud wall. I've decided to try and fit an arrestor. There seem to be two types - mechanical ones like sioux that use an air-sprung piston...

Any idea of the difference between the following Johnstone's vinyl matt paint please? Cleanable Durable Ultralast Thanks

Hi I have bungalow and think the best place to fit a camera is part way up the roof. I think they are Marley Ludlow or Redland 49. What's the best way to do this? I was thinking of: 1. Pushing up a couple of tiles to get to a batten. 2. Screwing a 20mm x 2mm aly strip to go down under the tile...

Hi Does anyone know the FD numbers that require a PCB upgrade with a pump replacement on a 30 CDI? My plumber says the pump has a slow leak on the casing. He explained certain FD numbers needed a PCB replacement with the new pump and was supposed to get back to me with a quote but is now on...

Hi All What is the standard wall detail with the new part L requirements please? I have a 2021 design with 100mm cavity bats and thermalite inner skin. I understand that's no longer enough? I guess the three options are: 1. 150mm cavity with rockwool batts 2. 100mm cavity with Kingspan 3. EWI...

I would like to make some furniture from plywood. I plan to leave the edge raw (clear Matt varnished) and the faces painted. Any tips on how to get a good finish? I will roller the faces using a short pile gloss roller. Would masking be sufficient to get a crisp edge? Or would you paint the...
