Opinion by
Henderson, J.,One of the defendants, J. L. Love, entered into a con*409tract in writing with the plaintiff to build a house for the latter. The obligation of the contractor was to provide all the materials and perform all the work for the erection and completion of a brick dwelling house in consideration for which work and the material used therein the plaintiff agreed to pay $8,707 at the times stipulated, in the contract. The contractor obligated himself to furnish “a satisfactory bond of the full amount of contract,” and this action was brought on the bond so given to recover money which the plaintiff was compelled to pay in discharge of certain liens entered against the property which the contractor failed' to discharge. The condition in the bond was that if the obligors “shall and do well and truly pay or cause to be paid unto the above named Robert Y. McCrum, his executors, administrators or assigns, the just and full sum of $8,700.00, eighty-seven hundred dollars, for the completion of a building as per plans and specifications and Article of Agreement for Robert Y. McCrum in the borough of Aspinwall, Pa., without fraud or further delay, then this obligation to be void,” etc. This clearly did not express the intention of the parties, and evidence was offered to show the purpose for which the bond was given the plaintiff’s allegation being that it was given to indemnify him against loss through failure of the contractor to carry out his agreement. The appellant alleged that it was given only to insure the completion of the building and that no financial obligation of the sureties was to be incurred. Under the authority of Huss v. Morris, 63 Pa. 367; George v. Tate, 102 U. S. 564, and other cases the learned trial judge held that resort should be made to oral testimony to ascertain what the agreement of the parties was and found as a fact that the bond was to furnish indemnity to the plaintiff against claims of subcontractors and material men. This conclusion was well founded on the evidence. That the contractor was bound to provide and pay for the materials and labor entering into the house is not *410open to debate. The consideration named covered the whole cost of the completed structure, and this the contractor expressly agreed to furnish. The bond recites the contract between the parties for the completion of the building according to the plans and specifications and article of agreement. Undoubtedly the signers of the bond did not understand that they were to pay the owner of the building $8,700 for its completion according to this contract. It was intended to be the “satisfactory bond” covering the contractor’s obligation which the plaintiff was entitled to have. There could have been no other reasonable object in providing the bond than to give security to the plaintiff that if the contractor did not perform his agreement the sureties would do so. The bond was prepared by the vice-president of the defendant company, and the president by whom the bond was executed testified that his understanding was that if the contractor failed to complete the building through sickness, death or other cause the appellant was obligated to complete it according to the plans and specifications. The appellant’s contention that there was to be no financial obligation is inconsistent with the terms of the paper, the purpose for which the bond was to be given as called for by the contract and the situation of the parties with reference to the transaction. Such a bond would afford no security to the owner of the premises with respect to the very things against which it was important that he be protected.
It is conceded that the claims which the plaintiff paid were liens against his property and that the bond as reformed by the court covered such claims. Objection is, however, made to the plaintiff’s demand for the reason that he voluntarily paid to other material men $2,598.05 out of the contract price on June 20, 1908, without waiting until liens were filed by these claimants. These payments were made on a written order from the contractor dated May 5, 1908, in which order the plaintiff was notified that the amounts were due the several *411creditors and that the plaintiff would have to take care of them as the contractor was without money so to do. These payments were not a departure from the eon-tract. The plaintiff was bound to pay the amount for which he had obligated himself if the contractor furnished the material and did the work. The material and labor covered by the payments made on June 20, was performance pro tanto by the contractor and as the building was completed at that time payments were due to him subject to the condition that he protect the owner from claims or liens. The ninth article of the agreement provided that if at any time there should be “evidence of any lien or claim for which if established the owner of said premises might become liable and which is chargeable to the contractor the owner shall have the right to retain out of any payment then due or thereafter to become due an amount sufficient to completely indemnify him against such lien or claim. Should there prove to be any such claim after all payments are made the Contractor shall refund to the Owner all moneys that the latter may be compelled to pay in discharging any lien on said premises made obligatory in consequence of the Contract default.” While this provision of the contract empowered the owner to retain a sufficient amount .out of the contract price to indemnify him against liens or claims there was no provision of the contract which required him so to do. That part of the agreement was in relief of the owner and was not intended to be protection to the sureties. The contract contemplated payment as the work progressed, and one of the objects in providing for security was to enable the contractor to obtain payments with which to purchase material and pay for labor. The contract contains no provision which bound the plaintiff to retain the amount due on the contract until it could be determined that there were no claims or liens with which he might be charged. There would be little use for a bond under such circumstances if the owner of the premises *412must retain the amounts due on the contract until the period had elapsed within which liens might be filed by subcontractors or material men. The case of Fels & Co. v. Mass. Bond, and Ins. Co., 48 Pa. Superior Ct. 27, rests on a different state of facts. There the agreement between the plaintiffs and the contractor required the plaintiffs to retain a certain percentage of the compensation to be received for laying the bricks, this retained percentage to be paid when the contract was completed. The contractor after having prosecuted the work for a length of time abandoned it. The plaintiffs, however, paid him in full for the work he had done including the twenty-five cents per 1,000 brick which was not payable until the work was completed.. This was an anticipatory payment not in harmony with but contrary to the express terms of the contract and' against the manifest interest of the surety. The retained earnings were intended as a fund to insure performance of the contract, and this incentive was removed when advance payments were made. The case of Alexandria Water Co. v. National Surety Company, 225 Pa. 1, is an authority in support of the judgment. The claims paid on June 20 were not disputed, they were admitted to be correct by the contractor and architect in charge of the work and the payment of them was performance of the contract to that extent by the plaintiff.
Under the contract, therefore, the liability of the plaintiff is established and the judgment is affirmed.
