    Hello Chaps,

    Looking to replace the bathroom window on first floor, gable end but there is no lintel currently and the 1st course of bricks above shows signs of dropping. My problem is the distance from the ground to above the window where i need to install the props/strongboys is about 5.3m. The longest acro i can get is about 4.8m.

    I feel like I'm missing a trick here, how is this job normally done when it's beyond the reach of acro props? Ill be working of a scaffold tower so don't want to run the props off that and stacking concrete blocks under the props sounds wrong too.

    I have done this before on ground floor windows and had it signed off by BC so its not a problem doing the job just the height required.

    Thanks
    Paul

    Possibly by using prop inside, spreading load with scaffold boards.

    How wide is the window? I bet if it's narrow some people wouldn't prop it at all.

    Window is about 1.5m wide. There is a concrete lintel on the inner leaf so its just the outer leaf I'm working on.

    1.5m wide opening is about on the limit (propping wise) but will depend upon where it is situated in the gable end.

    A gable end, particularly near the top, is the least favourable and the most vulnerable part of a building to tamper with, due to lack of self arching and the added headache of possible purlins etc.

    Here's us attempting a large opening in a vulnerable part of a gable complete with doubled up acros (stacked on top of each other) and needles....

    Sorry about the blurry pictures but here is the size of the finished opening. We fitted a Catnic 90/100 cavity lintel to the opening...…
