Hi Wonder if someone can shed some light on this very 'grey' topic for me. We have a Halstead Best 60 boiler, Gravity Feed hot water to a cylinder in loft and pumped CH. Currently this is controlled by a Potterton 2000 timer. For Hot water I can slide a switch and when the timer activates...

Hi Looking to completely replace fence, posts seem to be held in with MetPosts. Dug around one today and had a bash at extracting the existing (rotting) post but it seems securely fastened into the MetPost. Looks like I have the MetPosts without the bolts on. Can anyone suggest an easy way...

Right, as usual I have had a look around and cannot find anything to quite match my question! I have an existing hardstanding which is now the base of my garage, which I have built up around it. The hardstanding has a slight slope on it allowing water to 'flow' into the garage rather than...

Hi All. I've finished all the structural work on my garage, just got some rendering to do to finalise the exterior and I am now looking towards the inside. I would like to make the garage a little more comfortable for working in the winter and want to minimise moisture forming on the interior...

Sounds like a fairly basic question, but just though I would check how many nails should be used at each rafter to secure the battens. Battens are 25x50, 600mm centre rafters and tiles are concrete double roman - if that help any. Cheers. c.

First of all thanks to all who have posted on this site, lot of useful info out there and its helped me imensly - we could do with a few more 'sticky' posts for common questions though, not sure how they get 'sticky'. Anyhow, one thing I learnt whilst doing my blockwork was getting the...

Any one had experience with this stuff? http://www.glidevale.com/fulmetal_rediroll.html Looks simple enough, but I wanted to know if it came with ridge batten brackets supplied and what would be the dimensions of the ridge batten - the same as the ordinary battens (25x50) Lastly, its...

Just looking up external beading and wondered if this stuff is any good? http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=101508&ts=02819&id=32449 It says to be used where the surface area is greater than 13m2 and that it flexes to hep prevent cracking? Is it used vertically or horizontally...

Hi I have just today placed the last block to my garage (yippie!) and wanted to know if one should wait for any period for the structure to 'settle' or anything - I cant think that this is the case, a couple of days for the latest mortor to go off maybe, but thought I would double check...

Just about to install some of these mid-span of my room-in-roof attic trusses (above detached garage) and wanted to know if they only provide lateral (read sideways I think) support to stop the joists wanting to turn over or do they help spread the load across the neighbouring joists in any...

Just looking up timber prices for joists, to get an idea of how much it will costs/quantities etc, and I cant help thinking the marked prices below are incorrect. I have taken them from the TP website (just went to ring them, but shut after 12 on sat). For joists (and rafters?) I assume I...

Hi Just looking over the Trada span tables for C16 and I have worked out that for my joists I could run with 38x220. 38mm seems a little on the slim side, I know its the depth that makes up the strength but just wanted to see if anyone has any advice along the line of 'Oh yeah, no one ever...

(I apologise in advance, far too long winded - the last two sentances are probably all you need to read but I know how you guys like your info!) Just running through some caculations and I would be grateful if anyone could confirm my 'workings'. Obviously I will check with lintel company etc...

Hi Read a few posts on screeding where the recommended depth for screed was between 50mm and 80mm. I will have a garage floor to finish off with screed, the existing hardstanding is on an incline with around a 200mm height difference from one end to the other (~6m long). 1) Would it be...

Hi What length Spirit Level do you guys find works best when building up block work etc? I have a 1200mm one but I tend to stick to the 400mm for individual blocks as its easier to handle. Watching a bricky the other day and I noticed his was larger then mine and I got to thinking :wink...

Hi Woke up this morning and forgot to cover the DCBs that I have aleeady laid, with the rain they have taken up water (you can see the darker water patch for a good inch or so on top of the blocks). Is it best to wait and lay only on to dry blocks or does it not really matter too much? I...

Out of curiosity - what happens when a bag of cement goes beyond the shelf life stamped on the side of the bag? (to be honest, I cant actually read the 'dots' that should make up the date!). I've done a little searching and it seems to be related to the additives they put into the cement to...

Hi Doing some block work for garage and just need to bring the level up on the first few courses of my garage, however the mortar gap seems like its going to be getting too thick at one end, varying from 40-60mm. A neighbour suggested that this is too thick (60mm) for mortar to take weight...

Just looking at doors - what size gap should I leave in my blockwork (100mm 440x210 DCBs) to fit a 838mm door and associated frame? I guess a gap of 2 blocks would make sense, but that would leave me with around 100mm wider gap than the door itself - is that too much? I've no idea what...

Hi All What the minimum distance that a door could be placed from a corner? This is for an external door (not an up and over, but a standard door to get into the garage from the house side) on a garage, Single skin DCB 100mm, apex roof aprox. 5m high. I've looked up the building regs...
