ORDER
This matter is before the court upon cross motions for summary judgment by defendants Chubb & Son, Inc. and Chubb Indemnity Insurance Company (collectively, Chubb) and plaintiffs Joseph and Carolyn Friedberg; motions to exclude expert witnesses by Chubb and the Friedbergs
BACKGROUND
This insurance coverage dispute arises out of the Friedbergs’ 2001 purchase of Masterpiece Policy 12281532-04 (the Policy) from Chubb. The Policy covers the Friedbergs’ home in Wayzata, Minnesota, and provides “coverage against all risk of
Gradual or sudden loss (Rot Exclusion). We do not provide coverage for the presence of wear and tear, gradual deterioration, rust, bacteria, corrosion, dry or wet rot, or warping, however caused, or any loss caused by wear and tear, gradual deterioration, rust, bacteria, corrosion, dry or wet rot, or warping. We also do not cover any loss caused by inherent vice, latent defect or mechanical breakdown. But we do insure ensuing covered loss unless another exclusion applies (Ensuing Loss Provision).
Fungi and Mold (Mold Exclusion). We do not provide coverage for the presence of mold, however caused, or any loss caused by mold, other than as provided under the Extra Coverage, [m]old remediation expenses. But we do cover mold resulting from fire or lightning unless another exclusion applies. “Mold” means fungi, mold, mold spores, mycotoxins, and the scents and other byproducts of any of these.
Faulty planning, construction or maintenance (Construction Defects Exclusion). We do not cover any loss caused by the faulty acts, errors or omissions of you or any other person in planning, construction or maintenance. It does not matter whether the faulty acts, errors or omissions take place on or off the insured property. But we do insure ensuing covered loss unless another exclusion applies. “Planning” includes zoning, placing, surveying, designing, compacting, setting specifications, developing property and establishing building codes or construction standards. “Construction” includes materials, workmanship, and parts or equipment used for construction or repair.
Id. at CI00176-78.
The Friedbergs’ home was constructed with an exterior insulation and finish system (EIFS) manufactured by nonparty Dryvit Systems, Inc (Dryvit). In June 2002, the Friedbergs received notice of a proposed settlement in a class-action suit concerning water damage associated with Dryvit EIFSs. See Bland Decl. Ex. C, ECF No. 78. On November 20, 2003, the Friedbergs signed and returned the “Claimant Information” form to Dryvit. See id. Ex. D. As part of the claims process, an inspector surveyed the Fried-bergs’ home. See id. Ex. E. The inspector recommended $9,321.75 in remedial work, of which $3,728.70 was to be reimbursed by Dryvit as part of the class-action settlement. Id. The Friedbergs did not perform the proposed remedial work. See J. Friedberg Dep. 128:4-129:12.
In December 2006, the Friedbergs hired nonparty Donnelly Stucco to repair a small hole in the exterior of their home. Best-land Decl. Ex. A, at CI00023. Donnelly Stucco discovered extensive water damage. Id. at CI00032. The Friedbergs notified Chubb on January 22, 2007. Id. at CI00031. On January 31, 2007, Chubb adjuster Scott Bestland and expert Larry Gubbe inspected the Friedbergs’ home. Sample cuts into the home’s exterior revealed water intrusion causing rot, mold and damage to the home’s wood framing and insulation. See id. Ex. B at CI00244-78. Bestland’s “Inspection Report” noted the failure of the EIFS: “[I]t appears that Dryvit has failed due to no vertical ‘control /expansion’ joints that result in Dryvit cracking because it cannot expand or contract. Once the Dryvit cracks, moisture can get behind resulting in deterioration within the exterior
Gubbe inspected the Friedbergs’ home again in April 2007, after the Dryvit cladding had been removed. In a July 23, 2007, report, Gubbe detailed the results of the January and April inspections, noting water damage to the home’s architectural beams, roof deck, and sheathing and framing members. Gubbe Decl. Ex. A at CI00073, CI00075-76. Gubbe concluded that the damage to the architectural beams and underlying walls was “primarily caused by the failure to install control joints or otherwise to provide for differential movement which caused the beams to develop cracks through which water could penetrate the EIFS cladding.” Id. Ex. A at CI00078. Further, Gubbe found that “the damage attributable to inadequate design and construction of the beams ... has been cumulatively occurring over a period of several years” and was not “attributable to a single event such as a storm or other climatic phenomena.” Id.
The Friedbergs’ consultant M. Steven Doggett inspected the residence in June 2010 and reviewed roughly 1600 photographs of the damage. See Doggett Dep. 35:16-36:2, 44:1-6. Doggett testified that design and construction defects allowed external water intrusion. Id. at 86:16-87:19. The external intrusion accounted for eighty percent of the damage to the home. Id. Ex. 2, at 3. Doggett concluded that “[t]he primary mechanisms for moisture intrusion included unsealed joints and cracks at wall penetrations, window cladding, roof penetrations, roof membrane terminations, parapet cap flashing, wall cladding, and sealent joints.” Id. Doggett explained that improper roof repair was the primary cause of the damage on the upper portions of the residence and that the mechanism of water intrusion in lower parts of the residence was due to the roof and “[ejntry through terminations of the EIFS; entry at rough openings of windows and other wall penetrations; [and] flashing details.” Id. at 88:13-19.
On August 7, 2007, Chubb denied the Friedbergs’ claim on the basis that the damage sustained was excluded under the Policy. Bestland Decl. Ex. D, at CI00081. According to Chubb, based on the inspections, “it was evident that water has intruded via the exterior roof and wall for sometime, resulting in gradual deterioration.” Id.
On December 3, 2008, the Friedbergs filed a complaint in state court, seeking a declaration that the Policy covers the damage to their home and asserting breach of contract and estoppel claims. Chubb timely removed. The Friedbergs moved for partial summary judgment before the parties engaged in discovery. See ECF No. 81, at 1. The court denied the motion, because it was unclear whether the evidence might show that an excluded peril was the overriding cause of the loss. See ECF No. 48. Following discovery, the parties now make cross motions for summary judgment and to exclude certain expert testimony.
DISCUSSION
I. Expert Testimony
Chubb seeks to exclude the testimony of the Friedbergs’ experts Thomas Irmiter, Michael Opela and M. Steven Doggett based on lack of qualifications and use of unreliable methods. The Friedbergs seek to exclude Chubb’s expert Larry Gubbe based on use of unreliable methods. The court limits its analysis to Doggett and Gubbe.
“The admissibility of expert testimony in diversity cases is governed by federal law.” Unrein v. Timesavers, Inc.,
[i]f scientific, technical or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training or education may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.
Fed.R.Evid. 702. Under Rule 702, the court acts as a gatekeeper to determine “whether the witness is qualified to offer expert testimony.” Schmidt v. City of Bella Villa,
An expert must possess the “knowledge, skill, experience, training or education sufficient to assist the trier of fact.” Robinson v. GEICO Gen. Ins. Co.,
Chubb accepts Doggett’s qualification to testify about the deterioration of building materials, but argues that he is not qualified to testify about the mechanism of water entry and the cause of the deterioration. In addition to a Ph.D in ecology and post-doctoral training in mycology, Doggett is the principal at Built Environments, Inc., a firm that specializes in the assessment and design of buildings. Doggett Decl. ¶¶ 1-2. Doggett has served as the principal investigator for over thirty buildings where EIFS was the sole cladding system, and has performed over 1000 hours of hygrothermal analysis
B. Reliability
The court must also “ensure that any and all scientific testimony or evidence admitted is not only relevant, but reliable.” Schmidt,
(1) whether the theory or technique can be (and has been) tested; (2) whether the theory or technique has been subjected to peer review and publication; (3) the known or potential rate of error; (4) whether the theory has been generally accepted; ... [5] whether the expertise was developed for litigation or naturally flowed from the expert’s research;*1056 [6] whether the proposed expert ruled out other alternative explanations; and [7] whether the proposed expert sufficiently connected the proposed testimony with the facts of the case.
Lauzon,
Both sides seek to exclude the opposing expert, because his conclusions are based on photographs rather than a method that physically tests and independently confirms a hypothesis. In short, each side seeks to disqualify an expert for using the method employed by its own expert. The court is unpersuaded. It would be nearly impossible and cost-prohibitive to construct a true and accurate model of the Friedbergs’ home in order to test each expert’s theory. Both experts relied on photographic evidence, neither performed a “spray test”
II. Insurance Coverage
“The court shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(a); see Celotex Corp. v. Catrett,
On a motion for summary judgment, the court views all evidence and inferences in a light most favorable to the nonmoving party. See id. at 255,
A. Interpretation of the Policy
In Minnesota the interpretation of an insurance policy is a question of law. Am. Family Ins. Co. v. Walser,
The insured must first establish a prima facie case of coverage. SCSC Corp. v. Allied Mut. Ins. Co.,
B. Prima Facie Case of Coverage
The Friedbergs argue that coverage exists because their home suffered a physical loss. The court agrees. The Policy provides “coverage against all risk of physical loss to your house.” Wolter Aff. Ex. 4, at CI00169. As detailed in Gubbe’s report, the Friedbergs’ home suffered a physical loss, specifically, damage to the home’s architectural beams, roof deck, and sheathing and framing members. Gubbe Deck Ex. A, at CI00075-76. Therefore, the Friedbergs make a prima facie case for coverage, and the burden shifts to Chubb to show that the Policy excludes the loss.
C. Construction Defects Exclusion
The Construction Defects Exclusion excludes “any loss caused by the faulty acts, errors or omissions of you or any other person in planning, construction or maintenance.” Wolter Aff. Ex. 4, at CI00178. The Policy defines “caused by” to mean “any loss that is contributed to, made worse by, or in any way results from that peril.” Id. at CI00176. The Fried-bergs argue that “loss” means “financial detriment,” and as a result, the Construction Defects Exclusion is limited to the replacement of faulty construction.
Even assuming that the word “loss” means financial detriment, the Policy excludes the losses incurred by the Fried-bergs. The Friedbergs argue that language in the Acts of War and Nuclear or Radiation Hazard exclusions show that the Construction Defects Exclusion only excludes construction defects and not resulting loss. The Acts of War and Nuclear or Radiation Hazard exclusions add the language “any consequence of any of these acts regardless of any other direct or indirect cause or event, whether covered or not, contributing in any sequence to the loss.” Wolter Aff. Ex. 4, at CI00178. This anti-concurrent causation language shows that the parties agreed that the doctrine of concurrent causation would not apply to acts of war and nuclear or radiation hazards. The absence of such language in the other exclusions only shows that the parties did not contract around concurrent causation; it does not undermine the plain language of the Construction Defects Exclusion to mean that it is limited to the cost of replacing faulty construction.
The Friedbergs next argue that the Construction Defects Exclusion does not
Moreover, the Policy excludes “any loss caused by” faulty construction, whereas the Buscher policy only excluded “loss to property ... caused by” faulty construction. Compare id. at CI00178 (emphasis added), with Buscher,
D. Concurrent Causation
The Friedbergs next argue that they are entitled to coverage because Chubb cannot show that the overriding cause of the loss was faulty construction. See Henning Nelson Const. Co. v. Fireman’s Fund Am. Life Ins. Co.,
Water intrusion is not independent of the construction defects. See Bloom v. W. Nat’l Mut. Ins. Co., No. A05-2093,
E. Ensuing Loss Provision
The Friedbergs next argue that the ensuing loss provision in the Construction Defects Exclusion restores coverage. Under Minnesota law, the insured bears the burden of proving that an exception to an exclusion Restores coverage. See SCSC Corp.,
In Bloom,
In the present case, the water damage resulted from faulty construction. Without faulty design and workmanship, water would not have entered the Fried-bergs’ residence; with faulty construction, water damage was inevitable. Here, as in Bloom, there was no “separable and distinct peril” that led to deterioration, rot and warping other than time. Therefore, the Friedbergs’ claimed loss is not covered by the Policy’s ensuing loss provision,
CONCLUSION
Accordingly, based on the above, IT IS HEREBY ORDERED that:
1. Defendants’ motion for summary judgment [Doc. No. 75] is granted;
2. Plaintiffs’ motion for summary judgment [Doc. No. 79] is denied;
3. Defendants’ motion [Doc. No. 71] to exclude expert witnesses is denied; and
4. Plaintiffs’ motion [Doc. No. 119] to exclude expert witness is denied.
LET JUDGMENT BE ENTERED ACCORDINGLY
Notes
. The Friedbergs motion and memorandum in support were filed after oral argument. Because the motion is related to Chubb’s motion and raises similar issues, the court addresses the Friedbergs' motion.
. Because the court grants summary judgment in favor of the defendants, the motion to strike is moot.
. These are the two experts relied on for purposes of this order. The court notes, however, that the Friedbergs’ additional experts, Irmiter and Opela, reach a similar conclusion as Doggett. Both opine that faulty roofing allowed water to enter the Friedbergs' resi
. Hygrothermal analysis studies the movement of water and heat through buildings.
. A test that determines where water migrates after making contact with a hard surface.
. Chubb argues that the Friedbergs' claim is barred by the two-year statute of limitations in the Policy. The court need not address this issue, because the court grants summary judgment in favor of Chubb. The court does note, however, that when viewing the facts in a light most favorable to the Friedbergs, a genuine issue of material fact exists as to when the Friedbergs were aware or should have been aware of their loss.
. In a diversity action the court must determine how the Minnesota Supreme Court would decide an issue. See Raines v. Safeco Ins. Co. of Am.,
. An ensuing loss provision cannot be used to circumvent other relevant policy exclusions. See Bloom,
