Appearances are everything, especially when it comes to mold growing on the inside of a 20-year old condominium structure. When tenants noticed mold around windows, Structural Preservation Systems (SPS) was hired to provide a long-term fix to this problem. Unfortunately, the owner had previously attempted several repairs that included caulking around the windows. However, because of poor original construction, this band-aid approach did not solve the problem.

To begin, SPS removed all siding from the buildings as well as any existing paper to inspect the condition of the sheathing underneath. Crews also removed all wood trim, vinyl soffit and fascia boards. The next step was installation and sealing of a new building wrap. The exposed window flanges were sealed and an aluminum drip-edge was installed above the windows and doors, as well as above the head trim. The trim material used on the areas repaired is PVC, which will closely match the existing material's width and thickness, yet provide a more durable solution.

SPS also removed and replaced all rowlock brick and flashing with aluminum through wall flashing. The balconies were also removed and rebuilt using treated materials and PVC trim on the beams and posts. The project also included removal of the existing wood railings, which were replaced with coated aluminum rails. To ensure a successful repair solution, SPS created a mock-up. The prototype included the bay, balcony and bump out elements from the front elevation. 

One of the main challenges on this project was the budget as the owner had spent a significant amount of money on previous attempts to solve the problem. As such, SPS worked diligently with the owner and members of the design team to find cost-effective, yet durable solutions. Another challenge was ensuring the safety for the surrounding homeowners. Crews had to be careful about dust as well as noise. 

The project, which began in May 2007, was completed by the end of the summer. The owner is pleased, as are the tenants.
