My contract renewed and nobody told me. Is that legal?
New Jersey has an automatic-renewal notice statute, and it does not reach a cleaning contract — on four separate grounds, set out above in the operator's own words rather than by omission. There is no general New Jersey duty to remind a customer that a service agreement is about to renew. That is why the deadline in your own document is the only clock there is, and why it is worth putting in a calendar whether you are leaving or staying.
Does the three-day cooling-off period apply?
A cooling-off window is about the day something was signed, not about a contract you are in the middle of, so it is rarely the answer to this question. It is also narrower than it is usually described: the federal rule is limited to services bought primarily for personal, family or household purposes, so it does not reach a commercial buyer at all. The rule, its exclusions and this company's own three-business-day policy are linked below rather than restated here.
They want the balance of the term. Is that enforceable?
It depends on what the clause measures and who the parties are, and the law runs in both directions — which is the subject of the money-clock section above. In a commercial contract between parties of comparable bargaining power the New Jersey Supreme Court has treated a stipulated-damages clause as presumptively reasonable, with the burden of showing it unreasonable on the party challenging it. Against that, the Appellate Division has struck a clause calling for the full contract price on breach as bearing no reasonable relation to actual damages, and the Supreme Court has collected out-of-state authority refusing a pay-the-balance clause because the contractor would receive its expected profit plus the value of services it was then free to sell elsewhere. The one request that works either way is documentary: ask for the invoices and the amortisation schedule behind the number.
Can I stop the automatic payments?
There are mechanisms and there are clocks — three business days before the scheduled transfer for a consumer electronic debit, with a fourteen-day written confirmation the institution may require, and a sixty-day billing-error window on a credit card. They are set out above. What none of them does is end an obligation under a contract, and using one instead of a notice is how a dispute about service quality becomes a dispute about non-payment.
Can they put a lien on my building?
New Jersey's Construction Lien Law defines improvement broadly, and it includes excavation, drainage, land clearance, grading and landscaping among the work it covers. Routine janitorial work is not naturally described by that definition, and no New Jersey decision applying the lien law or the Prompt Payment Act to janitorial services was located for this page. The honest position is that the better reading puts recurring cleaning outside both, that the Prompt Payment Act's reference to performing labour upon a structure is the argument on the other side, and that a clean-down inside a live construction project is a different animal. Where the building is owned by a public entity the lien law excludes public works and improvements contracted for and awarded by a public entity, which disposes of it separately.
Can they keep the keys until the final invoice is paid?
The recovery question and the leverage question are different, and the second one is not worth entering. New Jersey's six-year limitations period covers the taking, detaining or converting of personal property and replevin, so nothing about physical property has to be resolved at speed. The step that actually changes your position is re-keying and deleting codes on a date you choose, which does not depend on anyone handing anything back.
Do I have to let them keep coming during the notice period?
That is what the notice period is: a term you agreed to, running to a date, during which the agreement is still the agreement. Barring access before it expires is the fact pattern in the case discussed above, where the customer changed the locks and ended up the party liable. If service during the notice period is genuinely unacceptable, that is a conversation to have on the record and under the contract's own terms.
What if I just stop paying?
The Appellate Division has held that a contractor's suspension of performance for non-payment was not a breach as a matter of law, and that the customer's arrangement with another firm was the first material breach — leaving the customer liable for the contractor's lost profits. Withholding payment feels like leverage and is frequently the act that decides who wins.
