I had a partial structural inspection yesterday. The client called me and stated she had an 80 yr old building, multi unit (apt on top and bottom) and since June she has started to see long horizontal cracking appear on the ceiling of east side rooms, both floors.
Upon inspection, after viewing the cracks, I went to the basement and checked it first. For a 80 yr old home it was very well built and in good shape. There were no signs of serious structural concern. The sill plate was completely intact and other than a few minor non differentral cracking in the foundation wall, I could not find anything that would lead to a major “shifting” of the home. She had the home wdi inspected about a month ago and was told the same thing…sill plate good, no wdi’s, all intact.
Next, I checked the attic from a hatch. It was completely open and all structural wood visible. Again, nothing out of the ordinary, well vented with open gable and sofit vents and everything looked good.
I checked the outside of the home and the only thing I discovered was the downspouts had no elbows and water was exiting into the ground on the west side. It was apparent that this was not a new condition and this has been happening for years. I can not figure out why this cracking would be just starting now (well since June of this year) and not for the last 80.
There was no water pooling or any of the sort. No damp conditions.
Can anyone tell me…is there something that I missed??
