EIFS OR A LOOK-ALIKE? LOOK FOR THE ASSEMBLY
COMMON EIFS
+ glass meshInsulation

wall
Look for the reinforced coating over insulation board. Confirm the complete system. [1, 9]
CEMENT STUCCO / INSULATED STUCCO

Cement plaster with lath suggests stucco. Foam can also be used with stucco. [6, 8]

A similar reinforced finish can cover cement board. Mesh alone does not prove EIFS. [7]
Outside → backing. Common layer concepts only; not to scale. Barriers, drainage, attachments and variants are omitted. Do not identify a system from color or this schematic alone.
CRITICAL INFORMATION TO COLLECT
- Building use / occupancy:
- Clad elevations / extent:
- Identification basis: visible layers, owner report or product / installation records
- System: □ Barrier □ Drainage □ Unknown □ Other
- Supporting documentation:
- Underlying wall / substrate:
- Installation year / source:
- Prior leaks / water entry:
- Repairs / dates / contractor:
- Recurring stains or patches:
- Sealant / flashing condition:
- Base clearance / outlet condition:
- Visible damage / photo IDs:
- Areas not observed / access limits:
Identify the cladding AND document the underlying wall construction separately.
WHAT MAKES IT EIFS?
EIFS: Exterior Insulation and Finish Systems. The insulation, reinforced base coat and finish form a non-load-bearing cladding. “Synthetic stucco” is a nickname; “Dryvit” is a brand. [1, 4]
Cladding means the outer wall covering—not the supporting wall.
- Insulation board attached to the backing
- Base coat with embedded glass-fiber mesh
- Protective finish coat
Drainage EIFS also includes a water-resistive barrier and drainage path behind the insulation. Details vary. [1, 9]
A textured finish can also cover masonry or cement board. Foam trim alone does not identify the main wall cladding. [7, 8]
If the assembly is not established, report “cladding type not verified” and request supporting records.
BARRIER vs. DRAINAGE
Barrier: Primarily relies on exterior face and interface details; no intentional drainage provision behind insulation.
With drainage: Water-resistive barrier + a path to discharge incidental water. Proper flashing and maintenance still matter. [1–3]
Appearance or age alone cannot confirm system type.
MOISTURE EXPOSURES
Water entry can expose underlying materials to prolonged wetting and deterioration. Damage may be concealed. [2, 3]
- Windows / doors and perimeter joints
- Failed sealant and open transitions
- Roof-wall intersections / diverters
- Parapet caps and visible flashing
- Pipes, signs, lights and attachments
- Cracks, punctures and missing finish
- Obscured base or blocked outlets
CODE / CONSTRUCTION FACTS
National use: Used in the U.S. and addressed in model codes. Installation / approval in all 50 states is not verified here. Local requirements govern. [2]
Grade: 2024 IRC §§R703.9.1–.2 specify at least 6 in. above finished ground. Residential model reference; commercial scope and local rules differ. [2, 5]
Fire / construction: Foam insulation is common; mineral-wool systems also exist. Stucco appearance does not establish masonry, noncombustibility or a fire rating. [4]
PHOTO CHECK – NEVER LEAVE WITHOUT THESE PHOTOS
GOOD CONDITION
- Accessible finishes intact
- No visible exposed insulation / reinforcement
- Visible joints and sealants intact
- Visible flashing appears maintained
- Visible drainage outlets unobstructed
- Base termination visible and documented
- Repair / maintenance history available
Visible indicators only; concealed damage is not ruled out.
HIGH PRIORITY CONCERNS
- Visible substrate deterioration
- Bulging, loose or separated cladding
- Active water entry / ongoing wetting
- Extensive cracking or missing layers
- Open interfaces with visible damage
- Recurring damage after repairs
- Loose material above occupied areas
Follow carrier escalation procedures; recommend qualified evaluation.
REPORT WRITING TIPS
- State identification basis and uncertainty.
- Separate observed vs. reported facts.
- Name elevation, location and visible extent.
- Reference context + close-up photos.
- Describe dark staining; do not diagnose mold.
- Record inaccessible / concealed areas.
- Recommend evaluation, not a guessed repair.
A visual survey does not certify drainage, structure, fire performance or code compliance.
