At the worst end, it's got to be 3" away from the wall. The facia board - see? Getting into the correct lingo now! - is maybe 6" top to bottom. With you saying it's not a heavy mass, do I assume that I don't need to literally fill the void, but (somehow) just fill/seal it along the bottom edge?Google for a brick mortar gun - Screwfix sell them as well - a mix of mortar not to thick and not too runny then you can squeeze mortar out at any angle and it should stick into the crack (as its not a heavy mass) then 30 mins later perhaps run a spoon handle or something smooth and gentle along the mortar to tidy it up - if you need to as its not going to be seen
I was wondering when someone would spot gutter3!A lot of roofs have eaves ventilation. My new build has it continuously between every rafter. Clearly in your case it is not where the mortar has fallen out but may be above the “facia” board. I have mentioned this just in case you decide to box it all in.
The other point to check is that this fascia is bone dry and no signs of rot. I would check particularly where the downspout from the main roof goes in the gutter. As this has probably been removed and replaced, does all the water from the main roof go into the gutter and go to the outfall without splashing over. It should have a shoe to direct it. It would be worth checking when we next have a downpour. Personally I would put a strip of lead here, going from under the tiles to inside the gutter, just to make sure that any water splashes out rather than in.
The downpipe on gutter3.jpg looks odd, it seems to go to the back/behind the gutter. Unless it is a duct for the cables.
I think I'll certainly achieve a 'bagged' finish, no matter what I do!Thinking again about how to fill the gap, I think I woild cut some ply, say 12mm thick, and cut it in strips say 100mm by 500mm. Get some galvanised wire mesh and roll it so it fits in the gap. Remove the mesh, fill the gap with stiffish mortar, push in the mesh, stainless steel screws through the fascia and in to the mortar/mesh mix. Then fill flush with mortar and put strip of ply horizontally between wall and underside of fascia, Fix ply to underside of fascia with screws So it acts as shuttering. Leave overnight then remove ply and fill any blemishes with fresh mortar, could use a piece of cloth to rub the surface to give it a “bagged“ finish.
Sound like your wife is fed up with building work. Moving house can be extremely stressful and most things are outside your control.I think I'll certainly achieve a 'bagged' finish, no matter what I do!
Yes, yours is certainly an idea to consider, so thanks for that.
(It's certainly a lot more constructive an idea than my wife's, which was "Can't we just move?"!)
That's very true, Spectric. A good point.Most of the suggestions are coverups, rather than get to the bottom of the problems lets just fill the gap and all will be ok, what is actually not yet been revealed?
