IMPORTANT!
This information is for guidance only. Each repair will be assessed for condition. From experience we can find in certain circumstances that it is possible to undertake 90% of the rebuild procedure to a satisfactory standard at stage 5, only to find that it is unacceptable/beyond economical repair, at which stage we would need to look into a more in depth repair or quote for a replacement.
