Hi Jayne, I'm sorry to hear you've had issues with your Tiling project. The builder is right that removing tiles from the plaster board surface could cause further problems as removing these tiles would almost certainly damage not only the tiles, but the wall itself making for further costs and repairs to wall. Silicone sealant can provide an excellent finish if done correctly and it comes in any colour you can imagine to give a matching finish. It can also be removed fairly easily so if you don't like the finish it doesn't have to stay. Failing that the only way to get other options on repair is to get out some Tilers to get a look and quote you on the options they present. Hope that's of some help to you.
