I'm about to install a shower tray onto a plywood base upstairs. Is it a good idea to keep insulation between the joists like there is accross the rest of the upstairs and also around/under the shower waste? That's what I have done for now as I guess there could be condensation if I don't and...

Hi, I'm going to level a concrete floor, just for smoothing out ready for a celotex floating floor to be installed on top. Looking at the Setcrete products, Any recommendations between either Latex one or Universal floor levelling compounds? I've used the latex one before but just wondered...

Hi, I've built a conservatory and i'm almost complete although I have one hold-up. Basically, the dwarf walls are done, floor slab laid, and i've even plastered and painted. My next step was to lay 75mm insulation on top of the floor slab and then put T&G P5 on top and then finally finished...

Hi, I am looking at getting my extension rendered with K Rend, total is 15sqm. Had a couple of quotes and just wondered if £700 for Materials and Labour sounded reasonable? Includes mesh and beading etc also. I live in the South. Thanks

Hi, I am finally getting a conservatory fitted soon having done all the brickwork myself. My question is, do the conservatory fitters usually put a vertical DPC where the windows abutt the house or is it usually just sealed? I will be plastering the inside so don't want to risk any damp etc...

Hi all, When we put down the DPM and poured the slab the DPM around the doors ended up being pulled tight across the internal leaf of the door threshold, I think because we made sure the DPM was quite flat on top of the sand. I assume the only way to solve this is to cut it and patch it up...

Hi, I laid my conservatory floor slab a week ago and I wanted to know if the screening is usually done straight after or is it usually done when the whole thing is finished and conservatory is installed on top of my walls etc... Thanks

Hi, I am finally going to lay the floor for a conservatory soon and I will be doing it like this (all credits to noseall :) When the dpm (green line in pic) goes up behind the insulation at the door, should the dpm be left going over the external dpc or to just meet it and cut off? Or does...

hi, I'm about to fill my cavity today :) all around for my conservatory dwarf wall to 225 below dpc. I have dropped the inner course of bricks down around where the doors are going. My question is does the infill need to be brought unto that level at the Same time as filling the cavity or can...

I need to fill my cavity to 225mm below DPC. What ratio is normally used and is it ok to use ballast for this or is it normally all separate (i.e for bigger stones etc..). Thanks

Hi, I will have a wall with 1 course of engineering bricks on it, the rest will be concrete blocks. Can these be rendered ok? If required I thought about going over them with a few angle grinder cuts to give it a key. The joints will be recessed. Thanks

Hi, I will have a wall with 1 course of engineering bricks on it, the rest will be concrete blocks. Can these be rendered ok? If required I thought about going over them with a few angle grinder cuts to give it a key. The joints will be recessed. I am not rendering over the dpc - we want a...

Hi all, Conservatory going very well almost at DPC and sorted out all the issues with blocks & bricks (frost etc..). Everything spot on a square and level. Very pleased. Are there likely to be any cracks/settlement issues if I were to do the entire outside skin in concrete blocks and then 1...

Hi, If I have some courses of blocks using 100mm block on the corners to get the bonding to work and then will put a row of bricks on the last course, what is the best way to get the bonding working for the bricks? The only way I can come up with is to use half a brick across the 100mm block...

Hi, I am building a conservatory cavity wall which the DPC will join to the bungalow dpc. Its an old bungalow we have and the dpc was done with slate and as you can see, its a pretty big mortar joint inc dpc (30mm). My question is, where would you recommend my dpc joins up to? It seems they...

Hi, I've used two courses of Celcon foundation blocks to get me up to a good ground level for a conservatory dwarf wall. However, I assumed because they could be used below DPC that they could be used above ground. I did not think about frost being new to these. Basically, in the worst area I...

Hi, I am building up to 75mm lower than the DPC with Concrete Blocks for a conservatory dwarf wall (one will also be 2.5m high on one side). For the last course to get to me to DPC level I will be using a brick. I just wondered if it would be best to use an engineering brick, class b or...

Hi, I have used foundation blocks which are 215 x 440 x 300 to get me up to ground level and now I planned on putting the usual size blocks 215 x 440 x 100 on top. Due to the width of the foundation blocks (300mm) I cannot work out how the bonding could possibly work out if I were to try and...

Hi, I just wondered if it was legally allowed to wire the live from a ceiling fan so the it is permanently wired in so it could be controlled independently to the light switch or if it was against the regulations? I know how to do it, I just wondered if it was allowed. The other half wants to...
