MEMORANDUM *

Jeffrey and Kathelyn Ludlow appeal the district court’s rulings denying them damages for loss of use and diminution in value to their home resulting from Lowe’s Home Centers, LLC’s installation of a refrigerator. We have jurisdiction under 28 U.S.C. § 1291.

We affirm the district court’s decision to deny the Ludlows’ claim for damages resulting from loss of use and diminution in value because the Ludlows failed to present competent evidence to support such damages. First, the district court did not abuse its discretion in striking the testimony of the Ludlows’ expert witness, John Ferguson, because the court’s determination that he was not qualified as an expert under Federal Rule of Evidence 702 was supported by the record. See Ollier v. Sweetwater Union High Sch. Dist., 768 F.3d 843, 860 (9th Cir. 2014). Likewise, the court did not abuse its discretion in striking specified paragraphs from the declaration of the Ludlows’ contractor, Matthew Boone. The paragraphs constituted expert testimony, and the court had previously excluded Boone from testifying as an expert because the Ludlows failed to timely disclose him. Without the excluded testimony of Ferguson and Boone, the Ludlows could not show their damages with “reasonable certainty.” Exotics Hawaii-Kona, Inc. v. E.I.

Honolulu Star-Bulletin, Ltd., 44 Haw. 567, 576, 356 P.2d 651 (1960)).
