Brickwork problem - I've a crack in my garage wall (single breeze block) which runs the full height of the wall but the crack does not run straight and goes through block and mortar. At the topthe crack is the thickness of the block, hence rain comes through even though outside is painted. How should I repair this? :?

mix a little sand and cement and fill it in,then using a damp sponge lightly rub over the area to smooth it out.

Thanks for reply

How can I get it the full thickness of the brick?

Do I need to open the crack up any more than what it is?

you can open the crack up,if its over 5-10mm use expanding foam to plug the gap and then mortar over once dried

hi I have just read your post. We are looking to buy a property and have noticed 2 cracks in the garage breeze block wall that runs from top to bottom. They don't reach the floor but stop just at the last bottom brick and don't go right to the top but again stop short of the top brick. The garage is integral to the house with a bedroom above. We have checked the outside of the house and there are no signs of any cracking on the outside or above in the bedroom or anywhere else in the house. The crack goes straight through some of the bricks. We are obviously going to get a full survey but not sure if we should even bother buying. The house is about 12 years old. The rest of the house is in good clean condition it is just these 2 cracks. I have photos just not sure how to attach them to this message.

it could be a couple of things,But it sounds like expansion has caused the crack.But Its only a guess.
Cracks can be worrying,but most of them are not serious and minor.I would recommend you have a full structural report,not a basic survey, a surveyor is not qualified or experienced enough to give you a detailed report.
A structural Engineer is held legally responsible for the report he gives you so he will be thorough in his examination.It is a little more expense but you have peace of mind.
