Trisco Construction Services (TCS) was called in to evaluate the Exterior Insulation and Finish System (EIFS) condition after an interior renovation project revealed extensive damage due to moisture on the inside of the hotel. The ownership group was very concerned because the hotel was less than ten years old.
We performed subsurface investigations and discovered construction detail defects. Flashing systems were not installed at the windows, PTAC units, transitions, or other penetrations. The PTAC units actually tilted inward which funneled the condensation into the wall cavity. This moisture caused the sheathing and wood framing to deteriorate.

It was determined that the entire façade needed to be replaced down to the stud framing, including replacement of rotten structural framing as encountered. All of the windows would need to be reset as well. This work would need to be completed while the hotel remained in operation.

A key component of the restoration was the installation of proper flashing around windows, PTAC units, and various building features to prevent future moisture from entering the building and to control the flow of water should it ever get behind the newly installed EIFS system.
This project is a prime example that water penetration, after only a very short period of time, will cause damage to a structure not to mention the interior finishes. This is especially true when proper flashing details are omitted during the original construction period. This damage to the structure would’ve likely gone unnoticed if it weren’t for minor signs of water leaks behind the wallpaper.
Our team was able to help the customer discover the problem, design the repair program, perform and install the repairs, and complete the project without interruption to the daily operation of the hotel.
