Flintlock gutters internal cracks

[Rebecca bishop]

Hi
Please help 1950 house flintlock gutters front and back.
Noticed internal cracks in all rooms at Exact height of where the flintlock guttering enters internal walls. They are horizontal cracks running all the way along. Stripped back paint work and some plaster to find large cracks (please see attached pics) there is also some black what looks like fibre in the cracks. Also from these horizontal cracks up to alcove seems to be slanted so not plumb to rest of wall - could this just be a previous plastering diy issue?
There are no damp problems Internally. The flint lock looks like it is in good condition with no sagging / dropping. Noticed Previous repairs done with mesh & plaster. Also roof line and tilling has been extended at some point And now goes over the concrete guttering with wooden facia and plastic guttering installed.Thank you for your time.

Looks like the steel reinforcement has rusted and expanded spalling the concrete. I would say you probably need new lintels above the window openings and patch repairs to the other finlock sections to remove or treat the rusted steel.

Hi thanks for the reply
In your opinion should I be worried about integrity of the structure at all? And would removing the flintlock ie cutting back to wall as commonly done resolve this? Or be part of the job to check lintel requirements
And fix if required. If removal Of flint L is needed at all? Also any ideas on the black fibre material in the crack? Possibly from past repair? Thanks

Something that extensive would indicate some movement of the roof to crack the gutter run.

One for a structural engineer to visit and assess

I thought the black visible in the crack was rusted steel bars. If it is in fact a fibrous material I would have to reconsider my answer. As Woody suggested someone needs to inspect the cracks to assess the cause and likely remedial works.

There has been quite a lot of input on finlock gutter systems I recall.
From your pictures it shows an historic issue of cracking previously patched. The scrim tape is a giveaway.
I doubt there's much you can do other than tape and repair the plaster.
You mentioned you have fascia etc. Has the finlock been cut back and new fascia and gutter fitted ?

Can you take a picture of the outside of the house showing the windows and roofline in one shot.

Hi thanks for the replies - datarebal - no, flint L not cut back - roof extended over concrete gutters and facia etc attached to FL
Mw roofline - yes will send pics tomorrow
Must also mention I posted this in building section too and chaps have mentioned possible movement of roof to crack gutter line.

Many thanks

Thanks for your time And quick response guys - just been looking into roof spread etc as mentioned by woody and it seems to be Fitting the picture although there are no other indicators Of this ie sagging roof line etc but if it is, I’m thinking would it be possible for the internal part of the flintlock to be pushed outwards and crack or bend at the gutter trough? May also be past owners altering roof timbers in loft - going to have a look at this tomorrow ultimately I will get a struc engineer in to look - in mean time do you have any tips for identifying problems in loft?

Apologies for duplicating post........

Hi pictures of roofline with windows if picture not clear enough will take another
Also timbers in loft all look ok and no internal wall cracks but I am v far from knowing what I’m talking about.......
