Fixing vertical foundation cracks is simple. The caulk in a healthy expansion joint more than five years old should appear to be compressed or extruded. It means rust had expanded for 25 mm 1 in. Since most walls constructed in pre-1919 buildings use lime mortar, the structure can accommodate such fine defects with little worry.

It should also be remembered that the crack may be caused not only by one of the above factors, but by a number working together to create subsidence, bowed walls, delaminated bricks and general deterioration of the masonry structure. We bought a 40 year old house that did not eaves troughs.
Settling and subsidence Some degree of excavation of the soil is usually required when a home is first built. So for 2 summers this noise has been going on. This process can involve having your foundations excavated and new concrete poured or injected into the site or underneath a foundation wall so as to bring it up to its original level.
