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.

Stucco Trim

Stucco Trim is the best material for exterior decor - the styrofoam is less prone to expansion and contraction while the cement coating provides a beautiful, high-end concrete finish.

Why Renovate with Stucco in Toronto?

Toronto is uniquely situated to reap the benefits of EIFS (Exterior Insulation Finish Systems) - otherwise known as Synthetic Stucco. Much of the high-end downtown core was built in the 30s and 40s using brick that is just now starting to wear and tear and needing attention. Home owners have a few options - they can leave it up and watch as their exterior walls fall apart (allowing water to intrude), they can tear it all down and put up more energy inefficient brick with high embodied energy, or they can simply retrofit their walls with EIFS, protecting the brick from further decay while increase the energy efficiency of the home.

Because most brick homes in Toronto are double-bricked, there is an airspace pre-existing in the wall. This typically eliminates the need for a weather barrier and drainage, however best practices dictate that a trowel-applied weather barrier be applied nonetheless, with vertical strips of adhesive holding the styrofoam boards in place. Over top of this, fiberglass mesh is embedded within a cementitious coating that will protect the wall while giving it great flexibility. This is key in the Toronto area as we see temperatures ranging anywhere from -40c to +40c. Finally, a beautiful acrylic finish coat is applied, with the owner or architect having and unlimited selection of colours, various textures and complete creative freedom over architectural shapes and ornamentation.
