Stucco Cracking, Efflorescence, and a Demand for Re-Stucco
An 18-month-old custom home in the Phoenix area has three-coat cement stucco over OSB sheathing. The owner reports hairline cracking radiating from all four window corners, white efflorescence along the base of the west elevation, and a soft, dark patch of sheathing next to a hose bib. At the patio, the stucco terminates about 1-1/2 inches above the slab; elsewhere it dies into grade. The owner's inspector wants the entire west elevation removed and re-stuccoed at $28,400, and the owner has filed an ROC complaint. Your own field review found no deflection in the frame and no visible interior water staining.
1. Separate the conditions that are genuine defects from those that are not, and explain what causes each.

Not defects: the fine cracking. Cement stucco shrinks as it cures, and hairline cracks under roughly 1/16 inch on a broad field are normal and expected. Calling them a defect concedes a repair you do not owe.
Defects:
- Cracks radiating from window corners. These are concentrated at re-entrant corners, which is exactly where corner reinforcement and control joints are supposed to relieve stress. Their presence at every window on the elevation points to missing or ineffective accessory reinforcement and possibly absent control joints - a workmanship issue, not curing shrinkage.
- Stucco terminating 1-1/2 inches above the slab. The termination at grade or paving is supposed to be at a weep screed with the proper clearance above grade and paving. At 1-1/2 inches, the assembly has no drainage path out of the base, so water wicks upward. That single detail explains the efflorescence, which is soluble salts carried to the surface by that wicking - a symptom, not the disease.
- Soft sheathing at the hose bib. A penetration with no proper sealant joint or flashing detail. Localized, but it confirms water is getting behind the cladding at penetrations.
What the diagnosis buys you: the efflorescence and the soft patch are both water-path failures caused by two identifiable details, not by the entire assembly being wrong. That is the argument against a full elevation rebuild.
2. Define a defensible repair scope and explain how you support it against the demand for full removal.

Scope by condition, with evidence behind each line:
- Base termination: cut back the stucco a minimum of 12 inches above the slab line, install a proper weep screed with the specified clearance, re-lath and re-plaster the band. This addresses the efflorescence at its source.
- Window corners: install control joints at the frames and re-establish corner reinforcement in the cracked zones; patch and re-finish.
- Hose bib: remove and replace the localized sheathing after moisture readings confirm the extent of damage, then reseal the penetration with a proper joint.
- Base coat and finish: blend new finish to match; texture and color variation will be visible, so get the owner's written acceptance of that before you start.
Support it with data: pin-type moisture readings of the sheathing at multiple grid points on the elevation, photographed and dated. If readings are only elevated near the base and at the bib, you have physical proof the failure is localized.
Handle the demand honestly: the owner is entitled to a watertight, code-compliant assembly - not to a new elevation. Offer a written repair proposal with a warranty on the repaired areas, and state what a full rebuild would cost and why it is not warranted. If the ROC process continues, your moisture data and the two identified detail failures are your case. Do not agree to the $28,400 in order to close the file; a fully funded rebuild of an elevation that is 80% sound is a business loss you cannot recover later.
3. What is your procedural obligation now that an ROC complaint has been filed, and what happens if you treat it as a nuisance?
Read the worked answer
Answer in writing, by the deadline, every time. The ROC complaint process runs on a schedule: the contractor's written response, then inspection by an ROC investigator or a third-party inspector, then a findings and corrective-work order, then appeal rights. Missing the response deadline is treated as a failure to respond and the case proceeds without your version of the facts.
What to file with the response: your contract and change orders, the moisture readings and photographs, your proposed repair scope and schedule, and a written offer to perform the repairs. The offer is the single most valuable document in the file - it demonstrates good faith and frequently resolves the complaint without an order.
What happens if you ignore it: an order to correct, your license placed on probation or subject to a civil penalty, the complaint history following you into future licensing and bonding, and the owner's Recovery Fund claim strengthened by a default. Ignoring a complaint never makes it smaller; it converts a repair of maybe $4,000-$6,000 into a $28,400 demand with the state's credibility behind it.
Practical sequence: respond, offer, repair, document with photos and a signed completion and release. Get the release in writing, and confirm in it that the owner accepts the blended finish.
