preparing window header after dodgy plasterer

[Mike]

i started a bathroom thursday but the dodgy plasterer had dry lined the window header but the board was overlapping the glass :yikes:. after removing the board i found there was only about 8mm gap for both the board and tile, on closer inspection the header was a poor/weak lathe and plaster. i had to remove it and start again . the wood lintels were well out of level so i had to add wood to level the header. sorry about the quality of the pics
