An elevator company filed a lien against a property for an unpaid monthly elevator service contract. For a fixed monthly fee, the property owner could call the elevator company at any time for repairs without having to pay any labor costs. After being refused service by the 1st elevator company due to a prior unpaid bill, the property owner stopped paying for the monthly service contract and started using a new elevator company for service instead without actually canceling the contract with 30 days notice as the contract required. The 1st elevator company continued billing for monthly service for 10 additional months before officially canceling the contract. The 1st elevator company filed a mechanic's lien 2 months later for the unpaid bills and the cited dates of last performed work and material furnished was 3 months prior (last month before service contract was officially cancelled). Does the service contract itself count as performed work and furnished materials even though the 1st elevator company hadn't been called to or even visited the property in 10+ months?
