Cracks in brickwork
 
1 Attachment(s)
I looked at a nice house up for sale, but noticed that there were some horizontal cracks in the brickwork at the top half of the walls. They look someone has mortared them in at some point in the past. They appear to be about every 4 rows.
Does anyone know if these could be a serious problem and what is the cause of them. Here is a picture that I took of the front.
Thank you.

You can't mortar in horizontal cracks. If the mortar looks different from the rest of the house, it's a repair. If it's cracked again, the cause of the crack is still there.

I must be getting old, I can't for the life of me see the cracks in the photo. Maybe my eyes, but I certainly can't help you understand the cause of cracking I can't see. Perhaps post a blow up photo with arrows showing the cracks.

Sorry, the photo is a bit small to clearly see the cracks.
They are where the lighter coloured mortar joints run along the main part of the house about every 4 rows. The cracks seem to be still there even though it was repaired and the mortar joints are much wider than the rest.
There are also some horizontal cracks upstairs in the plasterwork.
The extension looks to be unaffected.

The vertical area of tuck pointing under the left eave was likely done to repair mortar deterioration caused by water running off the roof (a gutter is needed there).

There is not enough detail present in the picture to determine much else.

The wall ties could be rusted which will lift up the brickwork.

If rusted wall ties are the problem is this an expensive job to correct the fault?

The bricks would need to be removed from the house and reinstalled using new ties. Figure about $8-10 a sq ft. plus removing, and cleaning the brick.
