5 Walworth, LLC v. Engerman Contracting, Inc.
963 N.W.2d 779
Wis. Ct. App.2021Background
- Engerman (general contractor) subcontracted Downes to build a residential pool; Downes bought shotcrete from Jacobs. The completed pool (2012) developed persistent cracking and leaks.
- A WJE engineering report identified inadequate rebar, porous/poorly installed shotcrete, cracking, soil saturation, and movement of surrounding masonry and pavers; Owner demolished and rebuilt the complex.
- Owner sued Engerman (contract, warranty, negligence, and Wis. Stat. §100.18) and insurers; Downes impleaded Jacobs for defective shotcrete; Engerman impleaded Jacobs for contribution/indemnity.
- Engerman’s insurers (West Bend, General Casualty) and Jacobs’ insurer (Acuity) defended under reservation and moved for declaratory judgment arguing no coverage: no "occurrence," no "property damage" (only damage to insured’s work/product or an integrated system), and exclusions applied.
- Circuit court granted insurers’ motions, finding no occurrence and that shotcrete/pool formed an integrated system so only the insureds’ own work/product was harmed.
- Court of Appeals reversed and remanded: factual issues remain whether defective workmanship/product caused an accidental physical injury (an occurrence), whether exclusions apply (subcontractor exception; "your product" exclusion), and whether policy trigger/known-loss issues preclude coverage.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether defective workmanship/product constitutes an "occurrence" | Resulting cracks, leaks and soil damage were unintended accidents caused by defective work/product, so an "occurrence" exists | Defective workmanship (or a defective product) is not an "occurrence" as a matter of law | Defective workmanship/product is not an occurrence per se, but unintended physical damage caused by them may constitute an occurrence; factual issues preclude summary judgment |
| Whether damage is "property damage" beyond insured's own work or product (integrated-system/third‑party requirement) | Physical injury to pool, surrounding walls, deck and soils is damage to other property, not limited to the product; coverage possible | Shotcrete became inseparable part of an integrated system; damage is only to the insured's product/work so exclusions bar coverage | Court rejects that the integrated-system rule is established on this record; factual questions remain and the "your product" exclusion cannot be decided at summary judgment |
| Applicability of "your work" exclusion and subcontractor exception (Engerman) | Downes was a subcontractor, so the subcontractor exception to the "your work" exclusion applies | Insurers contend exclusions still preclude coverage | Subcontractor exception likely removes the "your work" bar; cannot resolve coverage on summary judgment given the evidence of accidental damage |
| Policy trigger / known-loss (West Bend) | Coverage may be triggered by damage that continued or manifested during the policy period | Any relevant property damage began before the West Bend policy and/or was known pre-policy, so no coverage | Record insufficient to decide whether some damage occurred during the policy period or whether insured knew of the loss prior to inception; remand needed |
