EIFS / STUCCO: THE MOISTURE LIABILITY SHADOW
EIFS is a sealed system; installed wrong, it traps water in the wall.
This page covers one problem. The full picture for this trade, including the other places margin leaks, is on the eifs / stucco operating system page.
WHERE THE MONEY GOES.
EIFS is a sealed system; installed wrong, it traps water in the wall. The first EIFS class action was filed in North Carolina in 1995, a 1999 national television investigation documented trapped moisture behind EIFS homes, and an entire remediation industry exists because of it: full removal and replacement runs $15,000 to $40,000 on a house, and construction-defect firms keep EIFS practice groups to this day. Modern drainage-plane systems fixed the design; installation quality is still the whole ballgame, and the installer carries the tail.
THE COST, SOURCED.
"The first EIFS class-action lawsuit was filed in North Carolina in 1995." (Construction Solutions engineering analysis, 2026) "Modern drainage planes have fixed most of the 'leaky EIFS' horror stories of the 90s, but installation quality is still the only thing that matters." (2026 cladding guide) "Key risk: moisture intrusion if caulking, flashing, and penetration details are improperly installed."
THE NUMBER TO MEASURE IT AGAINST.
EIFS / Stucco contractors run about % net profit at $1M to $5M, rising to roughly 10% at $5M to $10M. The CFOS target at $1M to $5M is10%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.
Gross margin over the same bands runs % to 24%, against a CFOS target of 10%.
