I'm purchasing a 3 year old stucco home and the inspector identified the the deficiency below. Does this sound correct? I contacted the current owner who contacted the original builder and the builder is not supportive, stating that isolation joints are not used in window installations. Any help understanding this would be appreciated.
Inspector comment: "Windows and doors have not been installed with isolation joints. When there are dissimilar materials, that expand at different rates, industry standards dictate that isolation joints be installed to protect against moisture intrusion
