Window Corner Leaks When Raining

Post by Handy Trev » Mon Apr 30, 2018 2:51 pm

Hi, so after this preparation-of-sand-cement-render-for-p ... 88347.html sloooow render and plaster job to get a first floor room into rough condition for storage/studio use, recently I've noticed leaks in both corners during rain (the room is essentially North facing). I never noticed this while the cement render was the only material on the wall, which is was for quite a while.
I checked the outside window frame corners for obvious wood and paint wear but it's actually pretty good and even during rain I can't feel overly damp corner patches outside :wtf: Wondered if this is an obvious sign of something other than the obvious to more experienced people?

I should have mentioned that I do plan to touch up the paint work in the summer, but checking to see if i'm missing something? Thanks

Is there a good mastic joint between the window and the masonry on the outside?
One day it will all be firewood.

I'm guessing not (having only just learnt this term), what would be the best way to fill this?

for one example, you'll also need a skeleton gun if you don't already have one.

Hope these help. Quite tricky to photograph it turns out.

it looks like theres been no maintenance on the frame for years.
moisture will be getting in at some points on both sides at the bottom of the frame.
ormaybe where its had a mortar fillet seal - you can see repairs of mortar have been carried out in the past on the stone sill.
and where the wood sill sits on a stone sill probly needs silicone sealing.
and then sanding off and painting.
maybe the wood sill near the parting bead is rotting and collecting water?

thing is you have a very old box frame thats not been attended to.
does the brick hood moulding have a lead flashing?

Yup, I plan to attend to the frame this summer, it's not as bad as it looks but I didn't want to work on it and miss something more structural. Excuse all the questions, I'm not totally sure about some of the terms here.
1) Is the "mortar fillet seal" repair you mention at the sides of the sill?
2) Is the "the wood sill sits on a stone sill probly needs silicone sealing" the same as "mastic joint between the window and the masonry" from @ayjay?
3) "does the brick hood moulding have a lead flashing?" If this the vertical bricks above the window, then no, I think it's just cement. If this is below those bricks, then I think it's some kind of very hard metal ... though as you can see it has dotted rusting, and cracking?

Looks like a lot of maintenance ...

in summer, after doing the maintenancewater test the frame opening with a low pressure hose pipe. start low , watch ,then work up.
the obvious repair is on the stone sill
maybe the fillets that run up the sides only need as above sealing.
the rusted metal is probly a lintel.probly best to leave it in unless it rusts and swells.
water can sometimes get behind perishing mortar an run down the inside of the box frame but it usuly shows high an low not like your stains.

Thanks for this. Just to double check. Is the circled area the stone sill work you recommend?

Right, it's summer enough to sort this out. Apart from wood filling, sanding and painting, are the circled areas the main silicone areas I should attend to? Thanks for all the help.
