Lack of Fibreglass Mesh Causes Cracks in EIFS

When it comes to cutting corners to save on EIFS costs, there are a few places stucco contractors typically focus on. These areas are not well seen during the installation process without someone watching them the entire time. Fiberglass mesh is embedded directly into the base coat, meaning that it is only seen for a few minutes, and once the base coat is applied, it is difficult to determine whether it actually is there. The problem is that an EIFS installation that does not have fibre glass mesh will last for a couple years without any visible indications of trouble, but WILL crack prematurely. This can lead to moisture infiltration and further damage to the wall system.

The Role of Caulking with EIFS

While not specifically the responsibility of an EIFS (stucco) contractor, caulking between the EIFS and wall penetrations (windows and doors) often falls on their shoulders. Ensuring that a low-modulus sealant is used will help prolong the life of the caulking, meaning fewer re-applications are required and preventing moisture intrusion that leads to rot, mould and infestations.
