Hi All. Only cut one as a template, and it fits ok for a first go. I have 15 degree pitch. My problem is that the height of the heel cut is only about 18mm to achieve the 100mm seat cut. I started to pencil the recommended 65mm height, but my seat cut would have been about 170mm, and best...

Hi. I would like to know if i can reconnect my wiring, (where it was temporarily terminated ) to my new, replacement extension. It was a bathroom and conservatory. Now it is bathroom and utility. All previous sockets ran on the ring main, all lighting was also from one circuit. The shower ran...

Hi. I sourced a couple of lintels a year ago, when trying to save money before my self build extension. My windows are 760 wide, plus 10mm allowance and 150 each side is 1070mm. The lintels are 1800 long. Is there a reason to use or not use please?

Wondering if its a problem with these measurements. Cavity wall, 100-100-100. Concrete filled, then beam and block. First line of wall ties 600 above concrete fill. DPC at 275 above FFL. ( this is one block above wall ties ). Thanks.

Hi. Quick one i hope. I'm at ground level, have just filled the cavity with lean concrete and will be laying final block for the beams to rest on. As i have the correct amount of 7.3 blocks left for the flooring, can i use my 3.5 blocks now for the wall, or do i have to change after the beams...

Hi. The BCO doesn't want toothing, and modern brick sizes are different to my 1897 house. He has told me that he wants a vertical cut, 100 mm inwards ( where the mortar joint is ) and 100mm deep to prevent tracking. ( i know its pointless, but anyway). As per photo, i have removed a 1939...

Hi. I will be demolishing an old extension next week, in which there are three rads. I would like to cap the flow and return at house wall level, so that when i replace with new extension, i can create a copy of the missing system. Can i just cap off the 22mm pipes, or is there a need to keep...

Hi. Can anyone tell me if there is a recommended size of concrete lintels, for bridging over where my waste drainage passes through the courses below ground level. I will be adding 150 to each end, and the opening will only be 110mm plus the 50mm all round for movement. ( plus maybe a little to...

Would like to know how to create the 5mm slot i seem to require, at the ridge for the airflow through my soon to be built roof. It will be Cembrit Jutland slates, sitting on 175mm insulation, between my 200mm rafters. Ventilation of 25mm needed, so i will counter batten. I can have grilles in my...

Will be starting rear extension (Bathroom) to replace same, in March. Will be having extraction as per regs, but not sure which position is best for shower, and extractor fan. Low end of pitched roof, or other end. i assume fan would be at highest point regardless, or are you supposed to get...

Sorry if asked before, i tried the search and didnt find the answer. I will be doing a bathroom extension next year. Demolishing old bathroom extension and starting again. All previous pipework will be capped off at junction of existing house until i build the new one. In most peoples opinion...

Hi All. will be starting around March and will have only upstairs loo and sink. ( putting temporary shower in garden). will take me around 8 months, hopefully. When i start demolition, which will take me a while, i will have upstairs toilet until i come to remove the old brick inspection...

Hi All. BCO made his initial visit yesterday for my rear extension. We just went over what i could and couldnt do, and a few things about how he wanted things done. I will be going with block and beam and it will be two rooms. I want one room to be a stepdown into it. I will put my stud wall at...

Hi all. Will be starting a single storey rear extension next March. This is to replace an old badly built one, housing our downstairs ( and only ) bathroom. I am going P.D, building notice, due to lack of funds, and doing everything myself, from new drains to getting a spark to hopefully sign...
