My kitchen is being extended and on the external cavity wall there are two windows, separated by brickwork. The windows are due to be taken out, and a new opening made, with a span of 2.6m, to extend the depth of the kitchen. I'm advised that 2 x Catnic Lintels (either CN6XC or the newer spec BHD100) will be suitable for the load, and that 3m lintels will be required to achieve the minimum required end bearing of 150mm.
Judging by the dimensions (height 219mm), three courses of bricks will need to come out, and I'd like to get the job done before the main build because needing to take out one course of bricks above floor level in the room above is preventing me from getting on with refitting a bathroom and installing the pipe runs for my central heating.
I know that the lintels themselves can be bought for around £250 + VAT, and wondered how big a job installing them would be, and what sort of cost should I anticipate (in the Midlands) for the whole job (supply & fit).
