Mr Inspector is a qualified building inspector in Melbourne and took the above photo during a building inspection in Springvale.
The house inspection Photo shows re-pointed wall cracks above a window. Re-pointing is carried out on cracks in brick mortar and involves the re-inserting mortar into the crack affected areas. Re-pointing should only be done when adequately assessed and cracks are classed as dormant otherwise if the cracks are still live cracking will re-appear after re-pointing. With minor masonry wall cracks it is advisable to monitor the crack for 12 months to ascertain if it gets worse or not before re-pointing.
An experienced building inspector will be able to advise you on the significance of masonry wall cracks.
