I was engaged by the developer to help with detection of water leaks through windows in a new residential development. The leaks were damaging carpets and it was important to detect source of the defects.
Examination of windows revealed they were poorly installed, without appropriate head flashing and also careless application of silicone sealant had blocked sill drainage. However, thermal imaging scan had revealed roof and plumbing leaks that the developer was unaware of.

The developer now had a lot more defects to deal with than he anticipate but al least repairs be done whilst he was still on site and before the residential units were occupied.
