Apologies for the long post...
I gather that using expanding foam to fill the gap between the frame and the masonry, then caulking with silicone, is the way to go.
I'm wary of putting in too much foam, in case it expands to the point of separating the frame further from the masonry. Does anyone have any tips? The gap between the frame and masonry is approx 1cm.
One issue I have to tackle beforehand is that one of the vertical sections wriggles. I have tightened the loose screw in the bottom half of the frame and checked the tightness of the screws in the horizontal section, but there is still a slight wriggle. Does anyone know if there might be another screw concealed in the upper half of the vertical section, which could only be reached if the spring mechanism was removed? Or will sealing using ex foam give it the stability it needs? It's a standard sized frame housing a single canopy door.
Lastly, out of curiosity, any guesses as to the material used in the existing seal as shown in the image below? It doesn't recede that far into the gap, is quite hard and must have been applied years and years ago.
Thanks,
Nick
