    "Yes you can take out the defected pointing around 30mm deep and put mental bars in and repoint which will stop any future cracks"

    "If it's a new property it's not uncommon for a small amount of initial settlement to take place which can result in cracking which usually appears above the Windows starting from the top corners at the end of the lintel projecting upwards and diagonally from there as this is the weakest area of the building . A recent update to nhbc regulations introduced last year states that two course of bed joint reinforcement be built in over every opening projecting past the sides of the opening by 600mm to prevent such cracking. If the property is older than a few years then the cracking will most likely be a result of movement in the in the foundations . There are many factors that can cause this some more serious than others some of the more common ones are poor quality of foundations concrete incorrect thickness or projection . Damage from near by trees roots or a high water table eroding the ground underneath the concrete.or shrinkage in areas where the ground.had a high clay content . If you get a cricketer to assess the job make sure you they can identify and diagnose the root of problem if they can't and just show up and patch it up it will only get worse."

    "I’d say just a bit of settlement tough to say without seeing it if it’s only minor then I wouldn’t worry at all"
