Why is it important to repair holes in EIFS?

Repair holes in EIFSIt is important to repair holes in EIFS sooner than later. Obviously, the holes in your home look terrible, but besides aesthetically, there are other reasons to get those repairs done right away. Every time it rains there is moisture penetrating the system through the holes. Any time you have moisture behind a portland based cement product it is not a good thing. Water is a powerful thing that can create a lot of problems over time. It really depends on the substrate and the moisture barrier to determine how much damage will occur. Most homes will have a substrate of OSB and a moisture barrier of some kind of cloth based barrier. This combination is something of a concern when you have holes in the exterior cladding, as moisture is absorbed by the foam and the cloth barrier has holes in it from installing the barrier itself and the mechanical fasteners that are used to install the foam, so the cloth barrier has many holes in it which are allowing moisture to penetrate the wood substrate. Behind the system there is no air flow, so the moisture is festering in and around the wood and given time is going to rot the wood. Leaving a few small holes around the house can cause some problems down the road. The winters here in Michigan are the worst for causing damage when there is moisture behind the system. Every time it freezes and thaws the moisture absorbed by the foam expands and contracts breaking down the cement coat a little at a time. After a bunch of freezes and thaws over the winter the layers of Alpha Base Coat weaken and eventually start to crack and even delaminate. Exterior Insulation and Finish system (EIFS) also known as Synthetic stucco or Dryvit ®.
