    Moving pipework in concrete floor

    Hi, I have a new radiator which is a different size to the old as it was a very old radiator and also very close to the wall as it had no fins. In the photo X marks the new location. I was planning on making a channel in the concrete floor and connect using plastic pipes and fittings, but...

    Live cable from 3 gang light switch

    Hi, I recently replaced and moved a light fitting. Whilst looking at the setup, I noticed the the live cable coming from the 3 gang light switch is just a single cable with no outer sheath (i.e just a live cable has been removed from a t&e). this doesn't seem very protective. The light switch...

    Insulation and loft boarding

    Hi, My loft has very little insulation (about 30mm), so want to top it up but also keep it as 70% boarded storage space. Should I: a) Add loft legs and wool insulation b) use wool insulation to 100mm, then foam board insulation (50-100mm) on top where I want to board for storage (270mm wool...

    Chimney repointing

    hi, I am looking to get my chimney stack re-pointed. It looks like it is lime mortar. The rest of the house has previously been repointed using cement, as I can see a few places where it is now failing and is a white crumbly mortar underneath. Does it matter on the chimney if it is pointed in...

    Ventilation through external wall

    Hi, I am looking at installing a stove myself (with build reg notice of course) as I will be getting scaffolding put up to get the chimney re-pointed. I want to get the Stovax Stockton 7 as I had it installed in our old house, but I'm trying to find a nice air vent of 40mm (or there abouts)...

    Insulation on concrete under floor tiles

    Hi, Our downstairs bathroom used to have laminate flooring over a concrete base. We are putting tiles down, but I am worried this will make the room colder as the old laminate and underlay would have been a bit of a barrier to the concrete. Can I use Warmup Insulating Board 6mm as it says it...

    Insulation in cavity

    Hi, I am currently putting in a new bathroom. We had to take the window cill off (it was actually some hardboard with tiles and the plastic over the top). Under the sill you can get into the cavity wall which shows some 25mm insulation. I was thinking of adding more where I can, it won't be...

    Honeywell st699 to st9400 install

    Hi, I want to replace my st699 with the 9400. The install/conversion guide looks simple enough, but what do I do with the cables that are marked not connected (ie 5 and 8). I also have no wire going to 4, but it wants me to put that into 2. Thanks Mike

    mitre saw

    I'm thinking of get a mitre saw and circular saw for a number of projects. There is a mitre saw on offer at the moment but it is not sliding with a Max cut of 120mm. Thinking ahead, we will be fitting a new engineered wood floor, but they are 145mm across. Would I be able to do two cuts with...

    expanding loop circuit

    I want to add two electrical sockets in my living room, so what I am thinking of doing is extending the loop from an existing socket, running under the floorboards to the new locations, then back to the existing socket. I need to take one of the wires out of the existing socket, and connect...

    under floor insulation

    Hi, I am putting down new engineered flooring over existing floorboards and I am thinking of insulating between the joists using mineral wool suspended with some chicken wire or plastic similar. I have two questions, will it make much difference if I am already putting underlay and another...

    under floorboard insulation

    Hi, I am fitting our new kitchen, and have had to take up most of the floorboards because a previous builder filled it up with rubble from taking out a chimney, so I have been clearing that out! I was thinking of insulating under the floor whilst I am at it, and wondering whether to use...

    New gas pipe?

    I want to move a gas pipe which feeds our boiler as it runs up the middle of our kitchen wall. A friend came round to look at the pipes before we knew it was gas and advised that if we ever want to upgrade our boiler (currently D effeciency 15KW) that we may have to upgrade our pipe which is...

    blocking chimney

    We are currently putting in a new kitchen. The first job was to get the chimney supported which had been removed by a previous owner. What should I do with the chimney which currently drops a fair amount of soot out? I know it still needs ventilation to stop damp, and the area will be...

    Downpipe drainage

    I am currently re-landscaping our small terrace garden and have a question about drainage from a guttering downpipe. Previously the downpipe went under some concrete from the edge of the extension and just into a rubble filled hole right by the foundations. We have now removed the concrete and...

    oak shelving

    Hi, I am looking at building some simple oak book shelving inbetween two walls. Is oak 19mm thick going to be strong enough spanning just over a metre? I think I will secure it to the walls on three sides with 19mm thick battons along the full length. Is this going to be strong enough to...
