The EIFS Details We Check Before Anything Gets Covered

EIFS gets a bad reputation from bad installations, not from the system itself. Properly detailed and inspected, modern drainable EIFS is one of the most energy-efficient claddings you can put on a building. Here's what we verify on every EIFS project — before anything gets covered.

The checklist

1. Drainage plane continuity. The water-resistive barrier and drainage mat have to be continuous behind the insulation board. Any tear, reverse lap, or missed transition becomes a leak that shows up two winters later.

2. Backwrapping at every termination. Exposed EPS edges are how water gets into the system. Every edge — openings, expansion joints, base terminations — gets backwrapped or receives a proper starter track. We photograph each one.

3. Sealant joint geometry. EIFS-to-window and EIFS-to-dissimilar-material joints need proper width-to-depth ratio, backer rod, and a sealant compatible with the finish coat. A beautiful wall with a 1/8" smear joint is a callback, not a completion.

4. Base coat thickness and mesh embedment. Mesh floating in the middle of a proper base coat resists impact; mesh telegraphing through a starved coat doesn't. We check thickness with a wet-film gauge, not by eye.

5. Kickout flashings and roof terminations. The single most common source of EIFS moisture damage we find on restoration projects is a missing kickout flashing. Did anyone check section 4.2? We flagged it — because on our projects, someone always does.

Why restoration work made us better installers

Half of our EIFS expertise comes from repairing other people's installations across Pennsylvania. Every failure we've opened up is now a checkpoint on our new installations. That's the quiet advantage of experience: our checklist was written by real walls.
