How do you plasterboard a steel that is not level?

We are renovating and extending a 1970s bungalow in Dorset. We parted company with our builder and are continuing the work ourselves. We found that the steels in our build had not been correctly levelled and one steel was installed 18mm lower at one end. This looked very poor against the head of our patio doors so we needed to box the steel with plasterboard using packers to produce a correct looking level finish. Thanks to both ‪ ‪@thetallcarpenter‬ and ‪‪@TheDIYGuy1‬ for some videos that gave inspiration. We had to use packers in addition to their suggestions to get the right result. #gapotape #selfbuild #housetour #plasterboard #constructiontips #constructionfail #granddesigns #constructionsteel

What a nightmare! When our steelwork was boxed in, building regs required them to use special fire-resistant plasterboard which is usually a different colour (pink). Was that not a requirement here? (or is all your plasterboard fire resistant?)

Hi, Duncan. As our build is all single story building control advised us that we didn’t need to use fire board or double board the steels. I did specifically question them on this as I had assumed fire board would be required as well.

Nice to see you back. The problems you have had to cope with the poorly fitted steelwork are tragic. You seemed to have got round it satisfactorily. Look forward to more update videos.😀👍

@@normanboyes4983 Thanks Norman. there are quite a few areas where poor workmanship has resulted in a lot more effort to get the right finish. This steel was very annoying, the window company told the builder when they measured but the walls were up and the roof was on so it was too late to correct it. I probably try and do things to much tighter tollerances than a builder would. If I were working with a builder again I would be checking the work much more during the build.
