One of the most critical design elements in a building are those keeping water out of the structural system. Flashing diverts the water and protects the building from rot and mold growth. If the flashing is not installed correctly, this can lead to damage to the building.



Flashing, while usually being a hidden element, is one that needs appropriate attention. Joints between materials expand and contract giving ample opportunity for water penetration into the structure.

The little details can save you money time and again in the construction process.

Little details make for a successful project. Little mistakes make for disasters that are hard to overcome. Here is the proper flashing detail for a window.
