[photos] Joist and floorboards visible from air brick, is this okay?

[Matt723]

Took the air brick out and saw that a joist runs right in front of it. there is a gap between the bottom of the joist and the ground however.

I am unsure but the visible planks might well be the original floorboards, covered by a think plywood layer and then the flexible vinyl floor taped on top.

No particular sign of damp inside the house however the floor does slope a lot (down towards the airbrick).

Is it normal to have the air brick positionned there? If not is it he airbrick that was raised (if that is even a thing?) or the floor that sunk?

Any pointers re this mystery (unless all is normal) much appreciated!

OP,
The ideal is to have unobstructed air bricks every 1.5M around the house under suspended floors creating through ventilation between elevations.
How many air bricks do you have on the wall in question?
The air brick you have might be OK with the gap between joist & wall but if necessary you could use a long chisel (uk.rs.online. 10mm cold chisel) to crack out some of the inner brickwork?

Thank you Ree!

This is a terraced house so there are party walls on both sides.

There are two air bricks at the front (both have the same joists in front of them) and two at the back. Interestingly at the back they are much higher than the floor but the wall is cavity (2016 extension).

Additionally there is also a large air brick under the step of the entrance door, going into the cellar.

Opening at the bottom would not work because I'd have to break the "tar" which I assumes acts a DPC (you can see it in the photo, it's right inside the airbrick, some sort of fabric looking a it like carbon fiber).i saw some l shaped airbrick that could work well but unsure how to slide it in without access to the inside...

Realistically I don't think I'm going to rip the inside of the lounge and jack up the joists and redo everything. There are no signs of damp inside although I can't rally check the end of the joists.

Is it a defect that the joist is right there ie should the air brick be lower or the joist in the other direction?

Also is it a problem at the floorboard are that low ie at the level of the top of the air brick?

Thanks!

Position is fine. No work required.
