Debris in Cavity Wall... Suggestions

[Kingo206]

Hi guys,

I have had a window retrofitted for a bathroom.

Whilst the window is great, I'm concerned about the debris in the cavity wall, it literally is from bottom to top of the exposed cavity... I'm assuming anyway.

Do you have any suggestions as to how one can remove it?!

Vacuum cleaner pipe, and/or a steel rod, with the end formed into a hook. Final option, break it up, so it falls all the way down to ground level, and remove bricks from the outer leaf, to clean out the cavity.

Good suggestions, thank you.

Aye an old Henry is ideal for the job, even some of the big bits if too big for the tube, if you are lucky, you can kind of suspend them on the end of the tube with the suction and gently pull them out.

OP,
Besides the other issue your frame appears to have been fitted too far forward?
Fensa (&Regs?) require frames to be 75mm from the face of the building.

Which floor is the bathroom on?

Ground floor. Lean to/Walk through to garden side of the building.

Is this still an issue?!

Just done some research, this is how it should have been done I suppose... I'm hoping this is a new building reg prior to my submission lol

edit: 2002 ... ffs

OP,
Thanks for the quick reply.
Frames set too far forward might attract more rain penetration - your call what you do about it, if anything, at this stage? But first solve the cavity debris issue?
Have you had any interior damp signs showing on that wall?
If the cavity is full with debris (& mixed somehow with insulation?) then my experience has been to remove six bricks and clean the cavity out from the six brick opening.

Looking at your post #8 attachment what in particular attracts your attention in that conventional build?

No I was pointing out the 75mm recess of the windows. However, I assume many of those are using Full rockwool Insulation within the cavity. I am using PIR boards and maintaining a 50mm air grap throughout.

The windows have been sealed all round with waterproof sealant, so it should be fine...

Yes for sure, I think we will get the debris removed. The builders were careless, unfortunately.

No damp whatsoever (touch wood)
