Just had a granny flat built at super slow speed, now the BIG problem I have is when I did the first fix and ran all the cables I somehow managed to pick up an old roll of cable and so when I've just got around to connecting everything up I discover it's half red/black half blue/brown the walls are painted carpet down and a very small roof space to work in plus extra wood up there since I first ran the cables which all equals a huge job to rip it back out, am I completly stuffed or if everything is correctly sleeved would it be passed?
