1. The condo units have severe leaks through the exterior facade. Upon destructive examination of the exterior of one unit, it was revealed that the buildings were not sided or flashed properly to protect against snow build up during the winter snows. Other minor problems were also discovered.
2. This photo shows insulation board which had un-taped joints and is not a substantial substrate for proper siding installation. All insulation board was removed and replaced with exterior grade OSB.
3. This photo shows the proper installation of gas pipe flashing and building felts.
4. This photo shows the installation of the rain screen drainage plane over two layers of building felt.
5. This photo shows proper window head flashing and installation of rain screen water diverter.
6. In this condo unit the west-facing interior wall was cracked and bulged inward. Upon destructive exterior investigation it was discovered that the end trusses were not properly tied to the top of the end wall. The wall is west-facing and subject to severe wind pressure causing the end trusses to deflect inward, bulging and cracking the gypsum board.
7. If you look carefully at this photo you will see two problems. First, the connector plates on the inside truss were damaged during installation. Second, the trusses were not properly tied to the top plates and the trusses have been displaced inward about 3/4” due to the wind pressure. The solution was to tie the trusses to the wall with metal connector plates and run new sheathing 12” past the joint between the bottom cord of the truss and the top of the plate.
8. In this photo you can see the improper installation of the head flashing at the trim board. This was removed and replaced as part of the truss repair project.
