Water ingress in hall and study above

[LANEYLOP]

Hi, I’m looking your thoughts on a water ingress issue I have. I am in a late 1920s terraced house. Red brick that has been pebble dashed and painted many times by the look of it. Above my hall is a small study and the window of the study is directly in line with the front door. The internal
plaster below the window in the study was powdery and blown in patches when I moved in two years ago, which I naively sanded and wallpapered over, not realising at the time that there was a bigger Issue. Directly below the study is my front hall and between the ceiling in the hall and the top of my front door and part of the side of the door there is large patch of efflorescence and the plaster feels blown in some areas. I have removed the sealant from the upstairs window outside (where pvc frame meets brick) and resealed as there was a few noticeable holes in the sealant at the bottom. This helped a bit and the wall
Above the front door is no longer showing damp wet patch however the efflorescence is still reappearing after I brush it off. Because the study wall is directly above the hall wall I am convinced that wherever the water is entering the house, it is causing the issue in both areas. Also, there is a concrete canopy above the front door and some cracks in the external render between the canopy and the windowsill of the study window which I filled, but hasn’t resolved ingress issue. In hindsight I think I should have ground our the cracks in the render before I to filled them with the waterproof cement I used so am thinking if I do this that it may help? Failing that, has anyone any idea how else the wet may be entering the house? I have had a new composite door fitted and there was a new roof put on the house before I bought it . The water ingress was an issue before I replaced the door. Any helpful advice and thoughts would be appreciated. The first photo is the wall in the study . Second is the front of house to show canopy, third is the hall before and after window was sealed showing some improvement. Thank you

If you pour water onto the canopy, where does it go?
Why does it have no gutter or downpipe?

Show us the flashing or other detail where the canopy meets the wall

What is the height of the canopy compared to the hall ceiling?

Hi,

Water just runs off the canopy towards the front so I assume it’s slightly tilted to slow for that perhaps. None of the canopies in the street have guttering or a downpipe on the canopies. There is no flashing evident unless it’s hidden by the render. As far as I understand the canopy is ‘set’ into the brickwork of the house. Ceiling height in hall is 99 inches and the canopy height (up to the bottom of the canopy ) is approx 111 inches. Thank you

Does the window cill above the front door have a drip groove?

Hi Andy, Yes the window cill has a drip groove.

Forgot to mention that I have also checked the drainage holes at bottom of pvc window frame by pouring water in at top when window open ( top part of window opens ) but water flowing out of drainage holes ok

The height and position of the wet does very much suggest it is coming from the canopy joint.

Do you have any other wet patches?

 

[LANEYLOP]

Yes. At side of front door inside

 

[LANEYLOP]

It’s more efflorescence there than wet.

OP,
Water is penetrating the render - previous attempts to make remedial repairs can be seen, plus the painting of your render was possibly another attempt at preventing water penetration?
The canopy appears to be part of the problem.
There's also water penetration through the sand & cement plinth on the left of the doorway, & through the plinth below the bay glazing.

A correct, long term solution on the exterior elevation would be to remove & re-new all the render - from ground level to eaves, & to remove the canopy & construct a correctly built & flashed & drained porch roof.
The bay roof flashing needs close up examining.

Inside the house: all damaged plaster to be hacked off, & replaced with a 3:1 sand & NH lime mix of render.
The door frame might be water damaged likewise the skirtings?
FWIW: the RWP hopper is insecure.
