Some bricks soak up a lot of moisture. So over time, the weather eats away the face. also if the bricks are damp and it freezes the frost blows the face off. Replace all damaged bricks and spray liquid silicone on all brickwork. Use proper products which when dry all brickwork look normal as before.

Bad weather can cause bricks to crack and shatter... (cold weather).
You can use a weatherproof sealer, to prevent further deterioration.

Make sure the bricks have proper mortar in the gaps where bricks are next to each other and try to keep moisture levels low on the bricks.

Lyndon · Answer

Deterioration is mostly down to the weather and soft bricks, if all the pointing is solid and intact wait until the summer and paint the bricks with a clear water proofer, also worth checking if your damp course is doing its job correctly

Most of the time it's due to bricks being weathered or a poor quality brick

James · Answer

If the bricks are permanently wet they will deteriorate over time.

Philip · Answer

If the wall is south facing with the heat can cause  dryness in the beds of mortar, if the damp course is broken, if one side of the wall /house hits most of the bad weather, make sure all the mortar joints are full /flush, and strong enough with the right ratio
