UNITED STATES DISTRICT COURT MIDDLE DISTRICT OF LOUISIANA

DARIN ARCENEAUX CIVIL ACTION VERSUS 24-356-SDD-EWD GREAT NORTHERN INSURANCE CO.,

RULING Before the Court is the Motion for Summary Judgment1 filed by Defendant Great Northern Insurance Company (“Defendant” or “Great Northern”). Plaintiff Darin Arceneaux (“Plaintiff” or “Arceneaux”) filed an Opposition,2 to which Great Northern filed a Reply.3 The Court has carefully considered the parties’ submissions, arguments, and applicable law, and is prepared to rule. For the reasons that follow, Great Northern’s Motion will be GRANTED and Plaintiff’s claims are DISMISSED with prejudice. I. FACTUAL AND PROCEDURAL BACKGROUND This case concerns an insurance coverage dispute over damages to the backyard patio of Plaintiff’s residence at 19747 Southern Hills Avenue in Baton Rouge, Louisiana (the “Property”), which he attributes to muriatic acid treatments applied to the brick and flagstone surfaces by contractors in October 2023 (the “muriatic acid treatments”). Plaintiff filed a claim under his homeowner’s insurance policy, which was issued by Great Northern for the period of June 2, 2023 through October 16, 2023 (the “Policy”).4 The claim was denied and this lawsuit initiated soon thereafter. The following facts are

1 Rec. Doc. No. 41. 2 Rec. Doc. No. 48. 3 Rec. Doc. No. 49. 4 See Rec. Doc. No. 41-4, p. 1 (stating policy “effective date” of 6/2/23); Rec. Doc. No. 41-13, p. 1 (stating policy was “canceled by insured” on “October 16, 2023”). undisputed except where noted. On June 17, 2023, Plaintiff retained Eduardo J. Jenkins, Landscape Architect and Planner, LLC (“EJLAP”), to perform repairs to his backyard fountain and surrounding pool deck (collectively, the “Patio”).5 Relevant here, the repairs included “regrout[ing] the pool deck in its entirety”6—a task which was performed by EJLAP’s subcontractor, Gregory

Harrison (“Harrison”), in late September 2023.7 During the regrouting process, an excessive amount of resin-based grout was spread over the Patio’s brick and flagstone surfaces, causing damage as it hardened.8 Plaintiff testified at his deposition that he “called into question” the faulty re-grouting in “early October,” instructing EJLAP to halt the project” and “[g]et this stuff off.”9 Soon thereafter, Harrison attempted to remove the excess grout and remediate any damage by repeatedly applying muriatic acid treatments and high pressure water washes to the affected areas.10 Due to several improper applications,11 however, the muriatic acid treatments resulted in a chemical discoloration of the Patio’s stone surfaces.12 The parties dispute both the timing13 and extent14 of Plaintiff’s complained of damages. In any event, Plaintiff

5 Rec. Doc. No. 41-10, p. 3. 6 Rec. Doc. No. 41-10, p. 2. 7 Rec. Doc. No. 41-6, pp. 2, 11. 8 See Rec. Doc. No. 1, ¶ 13; Rec. Doc. No. 41-9, p. 1. 9 Rec. Doc. No. 41-5, p. 79 10 Id; Rec. Doc. No 41-7, p. 6; Rec. Doc. No. 41-9, p. 1. 11 Rec. Doc. No. 41-5, p. 183:1-7 (stating the parties’ agreement that the complained of damage was caused by improper application of the muriatic acid by “[EJLAP] and/or Greg Harrison”); Rec. Doc. No. 41-9, p.1. 12 Rec. Doc. No. 41-5, pp. 85-86; Rec. Doc. No. 41-6, pp. 2-3; Rec. Doc. No. 49-1, p. 1. 13 Plaintiff’s first documented communication identifying damage was an October 22 text message to Linda Jenkins, the wife of Eduardo Jenkins. Rec. Doc. No. 41-11, p. 29. Plaintiff’s sworn deposition testimony, however, represents that he first noticed discoloration and changed “physical properties of the stone” in “early October.” Rec. Doc. No. 41-5, p. 85:5-11; see Rec. Doc. No. 48 (stating Plaintiff’s position that he first observed acid discoloration before October 16, 2023—the Policy’s cancellation date). Further, he contends that “[t]he acid damage was chemically and physically occurring from the moment of application.” Rec. Doc. No. 48-1, p. 4. 14 Plaintiff identified numerous cracks on the Patio bricks which he attributes to over-exposure to muriatic acid. Rec. Doc. No 41-1, p. 6; see Rec. Doc. No. 41-6, p. 2 (“damage to the property consisted of chemical deterioration and discoloration”). Great Northern’s investigation, however, attributed the “cracks noted in contacted EJLAP as early as October 22, 2023, to report discoloration “in quite a few places” where excess grout had been removed.15 On October 30, Plaintiff contacted EJLAP to inform them that “the flagstone is permanently stained” and must be replaced, instructing the company to “file a claim with your insurer.”16 It became clear on November 7, however, that EJLAP was not covered by a professional liability insurance policy17 and

did not have the means to pay the damages.18 Plaintiff filed a notice of claim with Great Northern on November 21, 2023, for the “permanently damaged … flagstone and brick,” which he attributed to EJLAP’s “inappropriately applying … mortar with strengthening resin over the entire service area” and “applying muriatic acid … and letting it sit … for longer than the manufacturer’s application instructions.”19 On December 8, 2023, Great Northern assigned Timothy B. Hassenboehler (“Hassenboehler’), a professional engineer employed by EFI Global, to inspect the Patio.20 An on-site inspection took place on December 12,21 during which Plaintiff informed Hassenboehler of the muriatic acid treatments.22 Hassenboehler’s

subsequent damage assessment concluded the Patio had been “damaged in a manner consistent with improper use of a cleaning agent … such as muriatic acid.”23 Following the damage assessment’s issuance, the parties attempted to address Plaintiff’s concern that Hassenboehler lacked necessary qualifications and issued erroneous findings

the masonry brick pavers … to natural phenomenon of masonry brick [which] existed prior to the reported installation of … the acidic material.” Rec. Doc. No. 41-16, p. 6. 15 Rec. Doc. No. 41-11, p. 29. 16 Rec. Doc. No. 41-11, p. 87. 17 Id. at pp. 94-95. 18 Rec. Doc. No. 41-5, p. 111:19-23. 19 Rec. Doc. No. 41-13, pp. 1-2. 20 Rec. Doc. No. 41-14, p. 2 21 Id. 22 Rec. Doc. No. 41-5, p. 122:8-10. 23 Rec. Doc. No. 41-14, at pp. 6-7. regarding the scope and extent of the claimed damages.24 The disputed findings did not relate to the cause of the claimed damages.25 On February 12, 2024, Plaintiff’s claim was denied by Great Northern.26 The denial letter explained, in relevant part, that Plaintiff’s claimed damages were determined to be the result of “workmanship” and therefore subject to the Policy’s coverage exclusion for
