Hi, can anyone tell me the process for cutting an internal doorway. Hallway to lounge?
The wall is a single block wall in a bungalow and doesn't support anything as it runs the same way as the roof joists. I presume I will need a lintel? even though there's only one block above where the new doorway will be.
Would you advise cutting the opening exaxtly to the size of the new door lining or to cut it bigger and put something like 100mm to 50mm timber in between to make sure it won't flex out of true?
