Plaintiffs’ sole assignment of error relates to the granting of Nationwide’s motion for summary judgment. After careful examination of the present record on appeal and the record and opinion in the prior action, we affirm the award of summary judgment in Nationwide’s favor.
 Plaintiffs first argue that the doctrine of res judicata does not bar their recovery for damages to the contents of their dwelling because there was no judgment on the merits in the previous action. The evidence before this Court is to the contrary.
Estoppel by judgment, or res judicata, has been defined as follows: “[W]hen a fact has been agreed on, or decided in a court of record, neither of the parties shall be allowed to call it in question, and have it tried over again at any time thereafter, so long as the judgment or decree stands unreversed.” Humphrey, et al. v. Faison, 247 N.C. 127, 133, 100 S.E. 2d 524, 529 (1957), quoting Armfield v. Moore, 44 N.C. 157 (1852).
In the first action against Nationwide, plaintiffs prayed for compensatory damages for the loss of their dwelling as a result of the 19 January 1978 fire and for punitive damages. At the close of plaintiffs’ evidence, the trial court directed verdict in favor of the insurance adjuster for Nationwide and in favor of Nationwide as to all claims for punitive damages. At the close of Nationwide’s evidence, a directed verdict with respect to the remaining claims in the complaint was entered in Nationwide’s favor, and plaintiffs’ action was dismissed. In its judgment, the trial court indicated *723that it was granting Nationwide’s motion for directed verdict on its counterclaim, in part, on the ground that plaintiffs breached the provision of the policy providing for an examination under oath of the insured. This Court dismissed plaintiffs’ appeal from this judgment because of Appellate Rule violations. This Court further examined the evidence in the record and concluded that plaintiffs failed to establish their cause against Nationwide. Judge Harry C. Martin, writing for the Court, explained:
Moreover, N.C.G.S. 58476(c) requires that within sixty days after a fire loss the insured shall render to the company a sworn proof of loss. Defendant Nationwide relied upon the failure of plaintiffs to comply with this requirement as a stated basis for its motion for directed verdict at the close of all the evidence.
In North Carolina, no action may be maintained on a standard fire insurance policy unless proof of loss has been filed within the prescribed sixty-day period following the fire. [Citation omitted.] N.C.G.S. 58-180.2 allows a claimant faced with the defense of failure to file timely proof of loss to plead that such failure was for good cause and that the insurance company has not been substantially harmed in its ability to defend. Plaintiffs failed to take advantage of this statute, and did not file any pleading or introduce evidence as provided thereby. Nor do plaintiffs contend in their brief that they did so. Plaintiffs followed this course of action although the trial judge had advised their counsel that he would allow an amendment to their pleadings for this purpose. This fire loss occurred on 19 January 1978; plaintiffs were provided with forms for filing proof of loss 24 January 1978. They did not file proof of loss until 27 April 1978, more than sixty days after the loss. By so doing, with nothing else appearing, plaintiffs have failed to establish their cause against defendant Nationwide, and the court for this reason properly allowed Nationwide’s motion for directed verdict.

Mangum v. Nationwide, supra, slip op. at 3-4. Pending the appeal of the first action against Nationwide, plaintiffs filed the present action seeking compensation for the fire damage to their personal property.
*724The record and opinion of this Court in the first action clearly show that the issue as to proof of loss was fully adjudicated. Pursuant to the doctrine of res judicata the parties were bound by this decision in all other actions involving the same matter. Bryant v. Shields, 220 N.C. 628, 18 S.E. 2d 157 (1941). The matter to be litigated in both actions involved coverage under a single insurance policy for loss of property caused by the same fire. The fact that the presiding judge in the first action did not expressly allow directed verdict in Nationwide’s favor because of failure to file timely proof of loss is not a matter of concern. Res judicata “prevails as to matters essentially connected with the subject matter of the litigation and necessarily implied in the final judgment, although no specific finding may have been made in reference thereto.” Craver v. Spaugh, 227 N.C. 129, 132, 41 S.E. 2d 82, 84 (1947). The matter of timely proof of loss was clearly pertinent to the issue of plaintiffs’ recovery under the insurance policy for loss caused by the 19 January 1978 fire. In the first action, the record on its face showed that plaintiffs did not file a timely proof of loss and chose not to amend their pleadings to allege a good cause for this failure. This choice was made at their peril. “As to them, they have had a day in court and an opportunity to be heard. The facts found by the court at that hearing are conclusive. They preclude any recovery in this cause.” Id.
 Plaintiffs have also argued that since they never raised the issue of compensation for loss of personal property in their first action, a subsequent suit on this matter could be litigated. We agree with Nationwide that plaintiffs are estopped from bringing their second action, because the claims for recovery of damages to personal and real property should have been litigated in one suit. The situation here is almost identical to Lisenbey v. Farm Bureau Mutual Ins. Co. of Arkansas, Inc., 245 Ark. 144, 431 S.W. 2d 484 (1968). The issue before the Arkansas Supreme Court involved the right of homeowners whose houses were destroyed by fire to bring successive suits upon their fire insurance policy, first to recover for the loss of the house and later to recover for the loss of its contents. The trial court held that the first suit barred the second suit. In affirming this judgment, the Arkansas Supreme Court emphasized that only one fire insurance policy had been issued; that one premium was paid to cover loss of personal and *725real property and that the same fire caused damage to the property. Based upon these reasons, the Court concluded that only one cause of action existed and that plaintiffs should not be permitted to subdivide this action.
The reasoning in Lisenbey is consistent with the general rule cited by our courts that all damages resulting from a single wrong or cause of action must be recovered in one suit. See Bruton v. Light Co., 217 N.C. 1, 6 S.E. 2d 822 (1940). This reasoning is also consistent with the doctrine of merger, a collateral aspect of res judicata, as applied in actions for installments of money under a single contract. See, e.g., Behr v. Behr, 46 N.C. App. 694, 266 S.E. 2d 393 (1980) (suit for arrearages in separation agreement). In Behr, this Court concluded, “Under the doctrine of merger, a party suing for the breach of an indivisible contract must sue for all of the benefits which have accrued at the time of suit or be precluded from maintaining a subsequent action for installments omitted.” Id. at 693, 266 S.E. 2d at 396. In the case sub judice, there was one action which arose from a breach of a contract to insure. Plaintiffs were correctly barred from splitting this cause of action.
