PER CURIAM.
Defendants, general contractors and their surety, appeal an order denying their motion to compel arbitration.
On August 11, 1975 plaintiff owners, Morris Krathen, August Paluzzi and Ralph Carloni d/b/a Fratex Properties, entered into a standard AIA contract with the defendant general contractors, Patrick J. Lyons, Jr. and J.W. Walter, for the construction of a freight terminal warehouse. With regard to the arbitration of disputes, the contract contained the following provisions:
"7.10 ARBITRATION
"7.10.1 All claims, disputes and other matters in question arising out of, or relating to, this Contract or the breach thereof, . . ., shall be decided by arbitration in accordance with the Construction Industry Arbitration Rules of the American Arbitration Association then obtaining unless the parties mutually agree otherwise. This agreement to arbitrate shall be specifically enforceable under the prevailing arbitration law. The award rendered by the arbitrators shall be final, and judgment may be entered upon it in accordance with applicable law in any court having jurisdiction thereof.
"7.10.2 Notice of the demand for arbitration shall be filed in writing with the other party of the Contract and with the American Arbitration Association, and a copy shall be filed with the Architect. The demand for arbitration shall be made within the time limits specified in Subparagraph 2.2.10 and 2.2.11 where applicable, and in all other cases within a reasonable time after the claim, dispute or other matter in question has arisen, and in no event shall it be made after the date when institution of legal or equitable proceedings based on such claim, dispute or other matter in question would be barred by the applicable statute of limitations."[

In September Lyons and Walter commenced construction and upon completion, Fratex, by letter of June 9, 1977, notified them of certain defects; but no corrective action was taken. On November 14 the architects notified Lyons and Walter in writing that the deficiencies were their responsibility to remedy. Again Lyons and Walter failed to correct the defects, and on February 14, 1978 Fratex filed a multicount complaint against Lyons and Walter, their surety, the architects and engineers. Thereafter, on March 15 Lyons and Walter filed a motion to compel arbitration. After a hearing, the motion to compel was denied. Lyons and Walter and their surety, Aetna Casualty Surety Company, appeal the denial order. We affirm.
Under the facts presented in the instant case, we conclude that Lyons and Walter failed to timely make demand for arbitration. As of June 9, 1977 they were put on notice of the defects and on November 14, 1977 the architects rendered their written decision finding that they were responsible for remedying the defects. Pursuant to paragraph 2.2.11 of the contract, Lyons and Walter had 30 days therefrom (or until December 14) in which to demand arbitration. Having failed to exercise their right to arbitration, they waived that right. See 4 Fla. Jur.2d Arbitration and Award § 13 (1978). Although paragraph 7.10.2 provides that the demand for arbitration shall be filed within a reasonable time, we find no abuse of discretion on the part of the trial judge in determining that a motion to compel arbitration filed more than nine months after the first written notice of a dispute and four months after the decision of the architects has not been filed within a reasonable time. Cf. Bickerstaff v. Frazier, 232 So.2d 190 (Fla. 1st DCA 1970).
Finally we note that Lyons and Walter never filed a written notice of demand for arbitration with Fratex, the American Arbitration Association and the architect as required by paragraph 7.10.2 of the contract.
Affirmed.
