I have bought wall starter kits to tie my extension walls onto the corner of our existing house but i have 2 questions. 1. Should i cut away a section of wall to tie the inside skin to the old inside skin prior to cutting away the wall much later when i am water tight. 2. how should the 2...

Thats what i figured. Roll on the dry weather then all set to start then, except the bloody builders merchant delivered 10 pallets of the wrong blocks today

Also, as this is an extension, if the existing DPC/brickwork is not completeley level across the lenght of the house, should i install mine at the same slope or perfectly level? If the later, what would the detail be where the new wall meets the old at differnt levels?

I am using thermalite blocks from concrete up. Can i use normal bricks in places too. I thought you werent supposed ot mix materials as the expand/shrink at different rates? Also, i am a little concerened about the amount of water at the moment. I know we have had a lot of rain recently but...

I am about to start the brickwork for our extension and am doing some setting out drawings. All the masonary will be either rendered or cedar clad so i am not worried about brick patterns for aesthetics. I have seen illustrations of how not to set the brick work out for supporting lintels...

I had my footings poured on saturday and i made a bit of a school boy error. The pegs that i hammered in to guage by levels obviously werent hammered in enought as when the concrete was poured in, they were knocked over resulting in only one level peg left to check against. After the rains...

Ok, thanks. Just read a lot on line about rain damaging the top surface and repairs/ grinding off needed, increased water content weakening concrete (which I struggle to believe as it will set under water) and even comments that a decent concrete company wouldn't deliver when raining. Thought...

I have dug my trench footings but it has rained ever since. Started off with a bit of puddling on the bottom but i have just pumped about 2 foot out tonight. The trench is 600 wide by 1000 deep and about 20 m long in total. I have about cubic metres due to be delivered on saturday but the...

Thanks. Just wanted to check I hadnt misunderstood it

I am just about to cast the footings of our extension and time to think about the next phase. I need to build a cavity wall and was wondering what the most cost effective materials are. I have been looking at thermalite turbo blocks (0.11W/m2k) and understand these can be used on both the...

I understand that the area of glass of an extension can be no more than 25% of the new floor area, however you can offset the area off window removed from the original building by the creation of the extension. Our extension (internally)will be 28.14 sqm the proposed amount of glazing is...

Not a bad idea, why didnt i think of that.

The cylinder is a range tribune. It is a twin coil for connection of solar should i get around to it, but at the moment i am only using one coil. Any idea on how to correct the temperature? i guess it would be the same with the wireless version.

Any info on this? Agile, you suggested my plumber was a numpty so do you know?

It is on the north east facing elevation fitted below the soffit of our bungalow. Instructions suggest higher up but I don't have much choice. There are no vents or anything in the vicinity. The boiler is on the other side of the house about 15m cable run away

He isnt familiar with the weather compensating controls and works closely with someone who usually would deal with this. And since he was doing me a favour with my boiler i havent paid for his partner to deal with this part. Any input?

My new system boiler is all up and running and working but i am not sure that it is working to its full potential. I have installed a Vaillant ecotec plus system boiler with the additional VRC430 controls and VR65 control centre. My question is, when setting up the controls you are asked...

Thanks for that Tiles were installed 5 years ago now and i have moved house since then but appreciate the input :lol:

Thanks That was a joke above by the way before the humourless jump on. Vaillant all up and running nowwith weather compensating controls. Thanks

thanks for that. What is the detail where it meets the foundation. Should a wall be built up to DPC and then timber frame on top? Do know detail around window frames/doors etc? Is there a website with a lot of this info on?
