¶ 19 We first examine whether the Bakers were legally entitled to recover attorney fees. In general, "Washington follows the American rule in awarding attorney fees." Dayton v. Farmers Ins. Group, 124 Wn.2d 277, 280, 876 P.2d 896 (1994). Under the American rule, a court may award attorney fees only if that award is authorized by contract, statute, or a recognized ground in equity. Vinci Constr., 188 Wash.2d at 625, 398 P.3d 1093. One such recognized equitable ground is the rule announced in Olympic Steamship. Under Olympic Steamship, "[a]n insured who is compelled to assume the burden of legal action to obtain the benefit of its insurance contract is entitled to attorney fees." 117 Wash.2d at 54, 811 P.2d 673.
¶ 20 The parties do not dispute that the Bakers were the prevailing party and thus entitled to reasonable attorney fees under Olympic Steamship.3 Consequently, our analysis focuses on whether the trial court abused its discretion in determining the Bakers' reasonable attorney fees.
III
¶ 21 The Bakers argue first that the trial court abused its discretion in failing to consider the "make whole" purpose of an award of attorney fees under Olympic Steamship. In essence, the Bakers assert that because the fee agreement with their attorneys wouldn't have obligated them to pay HBH one-third of the gross recovery from Fireman's Fund, any award of fees less than that amount does not make them whole. We disagree.
¶ 22 At the outset, we agree with the Bakers that the equitable purpose supporting an award of attorney fees under Olympic Steamship requires that the insured be made whole. As our Supreme Court has explained: "when an insurer unsuccessfully contests coverage, it has placed its interests above the insured. Our decision in Olympic Steamship remedies this inequity by requiring that the insured be made whole." McGreevy v. Oregon Mutual Ins. Co., 128 Wn.2d 26, 39-40, 904 P.2d 731 (1995); Panorama Village Condominium Owners Ass'n v. Allstate Ins. Co., 144 Wn.2d 130, 144, 26 P.3d 910 (2001). We disagree, however, with the Bakers' assertion that because the trial court failed to award attorney fees at a level commiserate with the contingency fee agreement between the Bakers and HBH, it failed to make them whole and therefore abused its discretion.
¶ 23 The starting point, and indeed, the "primary consideration," in determining an appropriate award of attorney fees is reasonableness. Allard v. First Interstate Bank of Washington, N.A., 112 Wn.2d 145, 153, 768 P.2d 998 (1989). Thus, in order to assure that an insured is made whole under Olympic Steamship, the attorney fee award *783must include all reasonable attorney fees, including all expenses necessary to establish coverage. Panorama Village, 144 Wash.2d at 144, 26 P.3d 910.
¶ 24 One established method of determining a reasonable attorney fee award is the lodestar method. Bowers v. Transamerica Title Ins. Co., 100 Wn.2d 581, 597, 675 P.2d 193 (1983). Under this method, the trial court first examines the attorneys' billing records and determines the number of hours that were reasonably expended in pursuing the litigation. Bowers, 100 Wash.2d at 597, 675 P.2d 193. The total number of hours reasonably expended is then multiplied by the reasonable hourly rate of compensation resulting in the lodestar fee. Bowers, 100 Wash.2d at 597-98, 675 P.2d 193. After the lodestar has been calculated, the court may then consider the necessity of adjusting the rate after considering the contingent nature of the work, and the quality of the work performed. Bowers, 100 Wash.2d at 598, 675 P.2d 193.
¶ 25 No Washington court has held the lodestar method is the exclusive method to determine reasonable attorney fees.4 By the same token, no Washington court has held that a trial court abuses its discretion by using the lodestar method in order to determine reasonable attorney fees. In this case, the Bakers agreed that the lodestar method was appropriate:
the proper measurement of a reasonable attorney fee is the same: the Court determines a base award by using the lodestar calculation: the reasonable number of hours spent representing the plaintiff is multiplied by a reasonable hourly rate.... The Court then determines whether that base award should be subject to a multiplier, primarily on the basis of the contingent nature of the fee and the risk of no recovery at the inception of the case.
The trial court did not abuse its discretion by accepting the Bakers' argument that the lodestar method was proper for determining the Bakers' reasonable attorney fee award under Olympic Steamship.
IV
¶ 26 The Bakers next claim that the trial court abused its discretion by excluding fees for work that were not necessary to pursue the claims against Fireman's Fund. We disagree.
¶ 27 Under the lodestar method, "the party seeking fees bears the burden of proving the reasonableness of the fees." Mahler v. Szucs, 135 Wn.2d 398, 433-34, 957 P.2d 632 (1998). In determining the base lodestar, the trial court "must limit the lodestar to hours reasonably expended, and should therefore discount hours spent on unsuccessful claims, duplicated effort, or otherwise unproductive time." Bowers, 100 Wash.2d at 597, 675 P.2d 193. "The hours reasonably expended must be spent on claims having a `common core of facts and related legal theories.'" Pham, 159 Wash.2d at 538, 151 P.3d 976 (quoting Martinez v. City of Tacoma, 81 Wn.App. 228, 242-43, 914 P.2d 86 (1996)). "Courts must take an active role in assessing the reasonableness of fee awards, rather than treating cost decisions as a litigation afterthought." Mahler, 135 Wash.2d at 434, 957 P.2d 632. The trial court is required to enter findings of fact and conclusions of law. Mahler, 135 Wash.2d at 435, 957 P.2d 632.
¶ 28 The Bakers claim that the trial court abused its discretion in excluding or reducing hours billed for four different matters. We address each in turn.
Fees Related to Tax Foreclosure
¶ 29 The Bakers' attorney time records show that they spent over 226 hours assessing the Bakers' outstanding tax bill and possible foreclosure on their property over the *784course of approximately 18 months. When the Bakers notified Fireman's Fund of the tax issue in December 2009, Fireman's Fund agreed to pay the long overdue bill within a week. The trial court excluded 211.7 hours spent on the Bakers' outstanding property tax bill and related foreclosure:
Claims related to the property tax foreclosure proceedings against the landfill property, for 211.7 hours, totaling $61,280.00. While HBH obtained a favorable result for [the Bakers] by getting Fireman's Fund to pay the outstanding tax bill, this was not an item covered by the applicable insurance policies and should not be included in fees awarded against Fireman's Fund. Arguably it does not fall within the contingent fee agreement HBH had with the Bakers at all.
¶ 30 The Bakers failed to carry their burden to demonstrate these fees were appropriate. Because Fireman's Fund promptly paid the tax bill after being notified, and the property tax bill was at best tangential to the Bakers' claims against Fireman's Fund, the trial court did not abuse its discretion in denying the 211.7 hours spent on the foreclosure issue.
Fees Related to PRP Claims
¶ 31 In May 2008, at the Bakers' request, Fireman's Fund agreed to pay Marten Law to prosecute claims against the PRPs. There is no dispute that Fireman's Fund paid Marten Law in full. The Bakers sought recovery for additional attorney fees by HBH for litigation against the PRPs. Fireman's Fund did not oppose some of the claimed fees including time spent attending depositions of witnesses related to the PRP claims, time spent reviewing discovery, or time spent for updates from Marten Law. Fireman's fund did, however, object to time spent by HBH for preparing for depositions, strategy and assessment of claims, hours spent reviewing documents that consultants prepared for Marten Law, and other duplicative tasks. The trial court agreed with Fireman's Fund that some of these hours should be excluded:
Fees related to [PLPs] which were pursued by [MLG] on behalf of [the Bakers], for 139.4 hours, in the amount of $58,292.50. [The Bakers] have not established that it was necessary to prevail on their insurance claims to incur these attorney hours when [MLG] had been retained by Fireman's Fund to represent them with regard to issues related to the landfill cleanup, including seeking contribution by third parties.
¶ 32 The Bakers argue that this time should have been included because the work related to the Bakers' insurance claims against Fireman's Fund. They point to specific entries where the trial court excluded time that was spent on issues relevant to both sets of claims, the Bakers' insurance claims and the PLP litigation led by MLG. The Bakers failed to carry their burden to demonstrate these fees were non-duplicative or necessary for the Bakers' claims against Fireman's Fund.
¶ 33 The trial court did not abuse its discretion in excluding 139.4 hours for duplicative work related to the PRP claims.
Fees incurred litigating against OneBeacon
¶ 34 The trial court excluded time spent litigating claims against OneBeacon, another insurer that had issued a policy to the Bakers from 1986 to 1987:
Fees related to claims against One Beacon, for 142.6 hours, totaling $65,540.00. Plaintiffs have not established that it was necessary for them to pursue these claims when the contribution claims were being handled by [MLG] on behalf of [the Bakers].
¶ 35 The Bakers argue that excluding time litigating with OneBeacon was error because of the common-fund doctrine: Fireman's Fund is required to pay for the Bakers' fees incurred recovering a contribution from OneBeacon because that contribution ultimately lowered the amount that Fireman's Fund had to pay to Snohomish County. (OneBeacon contributed $300,000 to the County.) The Bakers claim that the trial court's factual mistake about OneBeacon's status - it was an insurer, but the court appeared to treat OneBeacon as if it were a PLP - compounded the court's error.
¶ 36 Here, excluding time billed on OneBeacon-related work was reasonable. First, *785the common-fund doctrine does not apply because in order to create the common fund, the insured must recover from the "at-fault party" and OneBeacon is not the at-fault party. Matsyuk v. State Farm Fire & Cas. Co., 173 Wn.2d 643, 650, 272 P.3d 802 (2012); see Mahler, 135 Wash.2d at 428, 957 P.2d 632 (discussing doctrine in context of insured recovering from tortfeasors, not another insurer).
¶ 37 Second, Fireman's Fund likely secured its right to contribution from OneBeacon at the time the Bakers tendered their claim to OneBeacon. This right was created by the continuous-trigger doctrine: when an insured sustains continuous damages all insurers providing coverage for any portion of the total time period of the continuing damage are jointly and severally liable for the entire amount of damage. Am. Nat'l Fire Ins. Co. v. B & L Trucking & Const. Co., Inc., 134 Wn.2d 413, 424, 951 P.2d 250 (1998). Here, since the landfill's environmental damage continued over time, under the continuous-trigger doctrine both insurers would have been jointly and severally liable for the entire amount of the damage at the time the Bakers tendered a claim to them.
¶ 38 Finally, the Bakers' argument that the trial court's factual mistake as to OneBeacon's identity somehow led to it misapplying the common-fund doctrine is unpersuasive. OneBeacon's identity is irrelevant to Fireman's Fund's liability under insurance policies.
¶ 39 The trial court did not abuse its discretion in excluding 142.6 hours for litigating claims against OneBeacon.
Fees for acting as the Bakers' personal counsel
¶ 40 The trial court excluded time that HBH spent as the Bakers' personal counsel:
Fees related to acting as personal counsel for [the Bakers] with regard to tax consequences of the settlement to them and other issues, for 46.7 hours, totaling $21,000.00. These issues were undoubtedly of importance to [the Bakers] but were not necessary to establishing Fireman's Fund[']s obligations under the insurance contracts, and appear to have been incurred after settlement was reached in March 2015.
¶ 41 The Bakers argue that the lodestar should include time their counsel advised them on the settlement's tax effects for two reasons. First, Olympic Steamship and the CPA allow a prevailing party to recover all of its fees, not just fees related to liability issues. Second, the CR 2A Agreement did not settle the case because payment from Fireman's Fund was contingent on the rest of the parties settling with the Bakers.
¶ 41 The trial court recognized that the issues regarding the tax consequences of the settlement were important to the Bakers but irrelevant to establishing Fireman's Fund's liability to the Bakers. Further, whether the Bakers would have reneged on the CR 2A Agreement had HBH not advised them is irrelevant: the record shows that they settled their claims against Fireman's Fund and that the parties in fact agreed to a settlement in principle.
¶ 42 The trial court did not abuse its discretion in excluding 46.7 hours for personal counsel.
V
¶ 43 The Bakers finally claim that the trial court abused its discretion by applying a 1.3 multiplier instead of their requested 2.5 multiplier. Again, we disagree.
¶ 44 After the court has calculated the lodestar, it may adjust it by applying a multiplier: "the lodestar fee ... may, in rare instances, be adjusted upward or downward in the trial court's discretion." Mahler, 135 Wash.2d at 434, 957 P.2d 632. "Adjustments to the lodestar product are reserved for `rare' occasions." Miller v. Kenny, 180 Wn.App. 772, 825, 325 P.3d 278 (2014). The lodestar is "presumed to adequately compensate an attorney." Miller, 180 Wash. App. at 825, 325 P.3d 278.
¶ 45 Courts can adjust the lodestar to account for two factors: the contingent nature of success and the quality of work performed. Bowers, 100 Wash.2d at 598, 675 P.2d 193. To account for the contingent *786nature of success, the trial court "must assess the likelihood of success at the outset of the litigation. This is necessarily an imprecise calculation and must largely be a matter of the trial court's discretion." Bowers, 100 Wash.2d at 598, 675 P.2d 193. The second basis, the quality of work performed, "is an extremely limited basis for adjustment because in virtually every case the quality of work will be reflected in the reasonable hourly rate." Bowers, 100 Wash.2d at 599, 675 P.2d 193.
¶ 46 The trial court agreed with the Bakers that the reasonable hourly rate did not reflect the quality of the work performed. The court disagreed, however, that the Baker's requested 2.5 times multiplier was appropriate and instead applied a 1.3 multiplier. The court explained:
while this case was complicated by long delays in part due to waiting on decisions from the Washington State Department of Ecology, the number of parties, and the combination of claims, it did not present complex or novel issue with regard to the insurance coverage issues. Furthermore, the probability of ultimately prevailing on the coverage issues was high because of Fireman's Fund's lack of responsiveness to Plaintiffs' inquiries from 2001 to 2005 and early assertions that there was no coverage under the policies. There is no evidence that HBH was required to turn down other profitable work because of this case.
After considering the entire record, the court is not persuaded that Plaintiffs have established that a 2.5 multiplier is appropriate. However, the court concludes that it is appropriate to take into account the exceptionally long pendency of this case during which time HBH received no payment of fees or reimbursement for costs, the exceptionally favorable result which they obtained on behalf of their clients, and the risk (albeit not large) that no recovery might be obtained. For these reasons, the court concludes a multiplier of 1.3 is supported by the record. This results in an attorney fee award of $1,209,757.25.
¶ 47 The court awarded a multiplier because of "the risk (albeit not large) that no recovery might be obtained," the length of time it took to resolve, and that HBH recovered no fees or costs for up to nine years. This are proper reasons supporting a multiplier. Bowers, 100 Wash.2d at 598, 675 P.2d 193. The court's decision also took into account the contingent nature of the Bakers' fee agreement. The court's decision is supported by its finding and substantial evidence. The trial court did not abuse its discretion in awarding
VI
¶ 48 Fireman's Fund cross appeals and challenges (1) the trial court's failure to deduct hours for additional unsuccessful, duplicated, and unproductive work, and (2) the hourly rates approved for the Bakers' attorneys. We address each in turn.
Additional Exclusions
¶ 49 Fireman's Fund claims first that the trial court erred in approving the following additional fees claimed by the Bakers: (1) 43 hours spent on a motion for summary judgment that was never filed; (2) time spent consulting with the Bakers regarding settlements that had already been agreed to; (3) time spent submitting claims for other defense expenses after the parties had settled; and (4) communications and meetings with the assessor's office and environmental consultants. We disagree.
¶ 50 The trial court rejected Fireman's Fund's argument that this work should be excluded:
Fireman's Fund has asserted that other fees should also be deducted. These include fees they designate as administrative, correcting discovery responses, duplicative/excess time, unnecessary/unsuccessful, vague[,] and not apparently related to the claims against Fireman's Fund. The court does not agree. For example, counsel is required to correct and supplement discovery responses. The charge for this is minimal, and the need is not out of line with what occurs in many cases. The time spent on researching a motion for summary judgment is not unreasonable and cannot *787be said to be unnecessary. The benefits of such research would still be applicable for trial and mediation of claims.
¶ 51 The record before us demonstrates that the court considered the entire record and found that this work by the Bakers' attorneys was reasonable and necessary. While Fireman's Fund disagrees with the court's decision, it fails to show that the court's decision was manifestly unreasonable. The trial court did not abuse its discretion in excluding hours from the lodestar.
Hourly Rates
¶ 52 Fireman's Fund claims that it was error to calculate the lodestar without evidence of HBH's actual hourly rates. We disagree.
¶ 53 When attorneys have an established rate for billing clients, that rate is likely a reasonable rate. Bowers, 100 Wash.2d at 597, 675 P.2d 193. The usual rate is not, however, "conclusively a reasonable fee and other factors may necessitate an adjustment." The court may also consider the level of skill, time limits imposed by the litigation, the attorney's reputation, and the undesirability of the case. Bowers, 100 Wash.2d at 597, 675 P.2d 193.
¶ 54 Here, the Bakers did not offer evidence of actual hourly rates charged by HBH. As the trial court explained, the fee agreement between the Bakers and HBH was contingent and consequently, HBH was not charging an hourly rate for its work for the Bakers. Instead, the trial court based its determination of relevant rates on declarations from several local attorneys that do similar work in the relevant legal community. The trial court concluded: "Based on the evidence presented, the hourly rates set forth above are reasonable for the type of legal work performed in this case in the Puget Sound legal community for attorneys and paralegals of similar skill, experience, and reputation." The trial court's determination of reasonable hourly rates was supported by substantial evidence and was not an abuse of discretion.
¶ 55 We affirm the trial court's fee award.5
