Wall ties or subsidence?

Question

How do you know if an exterior crack in the wall is subsidence or wall tie problem.

Brendan · Answer

Hi most of the time it’s subsidence or drainage problems or needs underpinnings not much under concrete footing

Stephen · Answer

It would very much  be subsidence and not tie wires

David · Answer

This very much sounds more like subsidence rather than anything else, best course of action would be to get a surveyor round and get a definitive answer

Kevin · Answer

It maybe subsidence but all depends 
which way the crack is going and how far it’s opened up 
There can be a few factors age of property may also
Be a factor 
Getting a local structural engineer would be the best way take some photos before hand and try getting as much information as you can

Leigh · Answer

Sounds like subsidence or could be settlement cracks 
How old is the house? I'd definitely think about getting a structural engineer in just to check it out

Cheyne · Answer

If the crack in the tiles  has only just  occurred 
And the tiles have been up some time.  . Then there is every possibility that it is movement 
I would not get to alarmed at this.  The weather rain etc we get now does this 
If the tiles have been laid on ply  then this can shrink and crack.  But would not be due to movmentbin the property 
Check externally fir visable cracks

David · Answer

Sounds like subsidence , the wall would be leaning of bellying if 8t was a tie problem

Shane · Answer

If it’s subsidence you will see it sinking and the crack will get bigger as it moves

Patrick · Answer

you dont! what you need to do is monitor the crack over a period of time and see if it gets  any bigger say 1 to 3 months if it does seek out a reputable builder! you can always get your cavity wall  checked out by a surveyor who can tell you if  have a problem or use a cavity wall specialist Perter cox Preservation do this i believe.

1.Crack Pattern: Subsidence-related cracks often appear diagonally, both horizontally and vertically, and can be wider at the top than at the bottom. Wall tie-related cracks may be more horizontal and might align with the rows of wall ties.
2.Location of Crack: Subsidence cracks usually start at a corner of a building, while wall tie-related cracks often appear closer to windows and doors or in the middle of walls.
3.Associated Factors: Subsidence cracks are often accompanied by other signs of movement, such as doors and windows sticking or becoming misaligned. Look for uneven floors, gaps around window frames, and other structural issues. Wall tie problems, on the other hand, might be more localized and not cause widespread movement.
