EIFS
Drainable EIFS installed to manufacturer spec across Southern Utah: insulation board, embedded mesh base coats, acrylic finishes, and EIFS repair.
01 / EIFS
What EIFS is
EIFS stands for exterior insulation and finish system, sometimes called synthetic stucco. Rigid foam insulation board goes over the sheathing, a polymer base coat with embedded fiberglass mesh goes over the foam, and a textured acrylic finish coat goes over that. Older barrier-type EIFS relied on the face of the wall to shed every drop of water. Modern drainable EIFS adds a water-resistive barrier and a drainage plane behind the foam, so incidental moisture has a way out. That single detail is the difference between the horror stories of the 1990s and the systems installed today.

How we install it
We install EIFS as a system, to the manufacturer's published details, not as a pile of parts. That means a continuous water-resistive barrier, adhesive ribbons oriented vertically so the drainage plane actually drains, back-wrapped board edges at every termination, and starter track with weeps at the base of the wall. Mesh gets fully embedded so the weave never telegraphs through the finish. Penetrations get sealant joints with backer rod, not a smear of caulk. Kickout flashings go in where rooflines meet walls, because that intersection causes more EIFS damage than any other detail.

When EIFS is the right choice
EIFS earns its place when continuous exterior insulation matters: it wraps the framing in foam and cuts the thermal bridging a stud wall suffers. It is also the practical way to build crisp architectural foam shapes, cornices, and deep reveals that would be heavy and slow in cement plaster. Builders reach for it on commercial facades and energy-code-driven projects. Homeowners usually meet EIFS the other way around: an older synthetic stucco home that needs repair, inspection, or repainting, and a contractor who can tell EIFS from hardcoat at a glance.
04 / Questions
EIFS FAQ.
Is EIFS the same as stucco?
No. Traditional stucco is cement plaster applied in three coats over metal lath, while EIFS is a layered synthetic system built over foam insulation board. They can look nearly identical once finished, but they are flashed, repaired, and maintained differently. Knock on the wall: hardcoat stucco feels like concrete, EIFS sounds hollow.
Does EIFS have moisture problems?
Barrier-type EIFS from the 1980s and 90s earned that reputation because water that got behind the foam had no way out. Modern drainable EIFS includes a water-resistive barrier and weeps at the base of the wall, so incidental moisture escapes. The system is only as good as its details, which is why installation quality matters more than the brand on the bucket.
Can damaged EIFS be repaired, or does the whole wall come off?
Localized damage, like impact holes, woodpecker holes, or hail bruising, can be cut out and rebuilt: new foam, new mesh, new base and finish coats blended into the surrounding texture. Full tear-offs are reserved for walls with widespread moisture damage behind the foam. A moisture inspection tells you which situation you have before anyone opens a wall.
