[¶ l.JMerle and Barb Lewis appeal the dismissal of a lawsuit against Benjamin Moore & Company. We affirm.
FACTS
[¶ 2.]The Lewises built a new home in Huron, South Dakota and used Benjamin Moore stain to coat and seal the siding. Within a-short time, the stain began to crack, chip and peel away from the siding, diminishing the appearance of the new home. Attempts to correct the problem were in vain and responsibility for the damage became a dispute between the Lewises and Benjamin Moore. Ultimately, the Lewises commenced a lawsuit against Benjamin Moore for breach of express and implied warranties. They sought damages of some nineteen thousand dollars plus costs and attorney’s fees.
[t 3.]Almost a year after the Lewises commenced their lawsuit, counsel for Benjamin Moore proposed a compromise agreement *888 under which an independent third party would be retained to analyze the siding problem and determine its cause. Counsel proposed that if the third party determined the stain was the cause, Benjamin Moore would pay the reasonable damages shown. Conversely, counsel proposed that if the third party determined the stain was not the cause, the Lewises would dismiss their suit. Counsel for the Lewises accepted this proposal and arrangements were made for a company named KTA-Tator, Inc. to analyze the Lewises’ siding.
[¶ 4.]KTA’s report ultimately concluded the problems with the peeling stain were not caused by defects in the stain, but rather by defective siding and the manner in which the stain was applied.
[¶ 5.]Benjamin Moore moved for summary judgment based upon a lack of any genuine issue of material fact over whether its stain proximately caused the damage to the Lew-ises’ new home. Benjamin Moore also filed a motion to dismiss or to enforce the compromise and settlement agreement with the Lewises. A hearing was held and the trial court subsequently dismissed the Lewises’ complaint with prejudice based upon the settlement agreement. The Lewises moved for relief from the order of dismissal which was denied. They now appeal to this Court.
ISSUE
[¶ 6.]Did the trial court err in dismissing the Lewises’ complaint?
[¶7.] It is settled law that if matters outside the pleadings are considered by a trial court in ruling on a motion to dismiss, the motion must be treated and reviewed as one for summary judgment.
See Wolff v. SD Game, Fish and Parks Dept.,
[¶ 8.]“ ‘The law favors the compromise and settlement of disputed claims.’”
Kroupa v. Kroupa,
[¶ 9.]Settlement agreements are subject to the same rules of construction as contracts. 15A C.J.S.
Compromise & Settlement
§ 21 (1967). Thus, whether a settlement agreement is ambiguous is a question of law.
See Watertown v. Dakota, Mn. & Eastern R. Co.,
[¶ 10.]Here, the correspondence making up the parties’ written compromise and settlement agreement was clear, certain and unambiguous. Benjamin Moore’s counsel proposed:
[T]hat an independent third party analyze the problems with your clients siding and make a determination as to the cause of such problems.
If that third party determines that the cause of the problems are [sic] associated with our product, then we would pay for the reasonable damages shown. If the independent third party determines that the cause of your clients’ problems are [sic] not associated with our product, then your case would be dismissed.
Counsel for the Lewises accepted, stating:
I forwarded [your proposal] onto the Lewis’s [sic] and finally had an opportunity to discuss it with them. We would be willing to go along with your proposals but obviously, we have a concern with exactly who will [be] conducting the independent tests.
Once the parties agreed that KTA would analyze the siding, counsel for the Lewises re-confirmed their acceptance of Benjamin Moore’s proposal stating:
[P]lease be advised that Merle and Barb [Lewis] are more than willing to go along with your proposal. Would you please let me know when you might be making the arrangements so that we can coordinate the effort.
[¶ ll.]KTA’s report concluded, “the Benjamin Moore coatings did not cause nor contribute to adhesion problems experienced on the exterior of the Lewis residence.” Given the unambiguous terms of the parties’ compromise agreement and the unambiguous conclusion of KTA’s report; nothing remained for the trial court’s consideration in an evi-dentiary hearing. Therefore, the trial court committed no error in summarily enforcing the agreement by dismissing the Lewises’ complaint in conformity with the express terms of the agreement.
[¶ 12.]Affirmed.
Notes
. This is trae even where the rales of procedure do not provide for a motion to enforce a settlement agreement.
