Hi, What would be the best fixing to use for installing a new upvc window that has to be secured directly into a catnic lintel. Thanks for any advice

Thanks for the reply. I'm not having a survey as I'm now going down the supply only route. Is it normal practice to give the glazing company the exact size of the opening or the the exact size of the windows reqd. I've read that some companies take off 10mm from the given size to allow for...

Hi, I am having a window fitted in a new build extension. Originally I ordered a supply and fit through a double glazing company (quoted £430). They told me the window would be installed in 3 weeks but a week and half later I hadn't even had the survey. I contacted them for s supply only...

Hi, What would be a rougth for the typical cost per m2 to skim a platerboard ceiling (26m2). I presume the cost per m2 would be slightly less for the walls. I'm going to get a couple of quotes but I'm trying to work out what to budget for. Thanks for any advice

Thanks for the reply. Another bizarre question but will it be Ok to have the cooker isolation switch within a kitchen cabinet. The isolation switch for the oven is is currently on the wall but we are installing tall larder type kitchen units so instead of moving the isolation switch can it...

Just done a google regarding diversity and have found the following information. The first 10A is counted and then 30% of the remaing amps. therefore presuming the oven is 6Kw and the hob 7Kw (both over exaggerated) then the total amps will be 54A. Therefore first 10A + 30% of 44A is...

The oven is 5.9Kw, can't find any info on the hob but aren't hobs generally more than an oven. I read somewhere on the forum about something called diversity, not sure what that is exactly but i was hopeing it took into account the fact that the hob and oven are never going to at their max power...

Hi, Currently replacing my kitchen and upgrading the oven and hob. The oven is currently run from its own 30A supply but the hob is connected to a 30A ringmain. The new hob is a Neff ceramic and I suspect it needs its own 30A supply. Is it at all possible for an electrician to wire the hob...

Hi, Structural engineer calcs state that the inner leaf for my pillars supporting a 5.5m bean should be constructed in 3.5N block work. Are thermalite blocks satisfactory for this?

Had a word with the builders this morning and they say there has to be a gap between the internal and external blockwork to prevent damp bridging. They say the insulation is laid over the floor and then screeded which is sufficient support over the gap.

The link shows the beams sitting on the internal block work, as with my floor. My point is, what happens when I have sliding doors so there is no internal blockwork and there is going to be a gap of 100mm where the insulation normally would sit.

Hi, I have just had a block and beam floor laid for my new extension, there is a 100mm gap between the floor and the external brickwork i.e the floor does not go all the way to the external brickwork. I don't see this as a problem where I am having internal blockwork but i am also having...

I take your point about joints but I don't think there is any other way. If you can imagine the mains water currently comes up under my sink on the rear wall of my kitchen. I am now going to remove that rear wall and move it forward 3m to create the larger kitchen, so have to get the mains...

Hi, I need to extend my mains water inlet pipe. I am extending my kitchen by 3m so need to couple onto the current mains inlet. We have block and beam flooring so is it just a matter of coupleing up to the old pipe and pushing some new blue water pipe to the rear of the extension under the...

Sounds expensive. Would it matter that 3m have already been dug at 2m depth and another couple of meters at 1m. i.e can you simply refill the trench and then pile. Thing is the skips already been collected so theres shag all to put back in the trench.

noseall, I don't disagree. My point though was that I haven't paid anything so could quite easily say i don't want it anymore but as I also said that would duly end in a court summons. I like to think I have a good relationship with the builder and there is no way I would contemplate...

woody, I did mention to him a couple of times that I was worried about the footings because of the retaining walls and he assusred me there would be no problem with 1m footing because the whole area is built on sand.

noseall, the reason why the extra depth is because my house is built on a hill. The house to my right is 6ft higher with a retaining wall and the house to the left 6 6ft lower with a retaining wall. The BCO came to inspect the trench and said that he would like us to keep digging until we hit...

No my decision to continue isn't going to depend on replies here but it will depend on the additional cost. When I asked the builder how much the additional cost was likely to be he couldn't say only the fact that he priced approx £7000 for the footings and flooring. If the costs were to rise by...

Hi, Having an extension built 3m by 10m. Builder priced it up for 1m footings but it looks like I may have to have 2m footings, the BCO is coming back tomorrow to confirm. The builder has warned me its going to add significantly to the costs i.e extra labour, skips etc. and then the...
