Halo Case Study · Plan-coordinated protection

    A leak during the ownership gap.

    At 5:12 AM, Halo detected water in a recently sold condominium unit. The prior owner was gone. The new owner had not visited. The protection was still active.

    The unit was in transition. The leak was not.

    One of them sprung a pinhole leak. Nobody was home.

    Halo found it, stopped it, and alerted the team — before any damage was done.

    Incident summary

    5:12 AM
    Halo spotted the water and shut it off — instantly.
    6:23 AM
    The board president walked in, traced it to a pinhole in the expansion tank, and confirmed the leak.
    The catch
    Nobody would have known to look — the unit was between owners. Halo's alert is the only reason anyone walked in.

    Water was found around the shutoff equipment and nearby wall surfaces before normal business hours.

    Evidence from the unit

    Captured before business hours

    5:12 AM
    Water detected. Water shut off. Alert sent.
    Halo caught it the moment water appeared, closed the valve on its own, and notified the building right away.
    6:23 AM
    Board president walked the unit and found the source.
    Because Halo had flagged it, someone knew to check. The unit was between owners — without Halo, no one would have looked.
    Source confirmed
    A pinhole leak in the expansion tank.
    A puncture barely the size of a sewing needle, in a tank tucked above the water heater.

    The actual source: a tiny puncture in the tank wall, no larger than a sewing-needle hole. Enough to flood a unit if no one is watching.

    Root cause evidence

    A small puncture in the expansion tank became a building-level response item.

    What the record made clear

    The response did not depend on a newly transferred owner already being set up, reachable, and watching an app. The event stayed visible to the people responsible for the building.

    Building standard

    Core lesson

    “The owner record was changing. The protection stayed active.”

    Owner-by-owner protection leaves gaps.

    The incident exposed the risk of depending on an individual owner handoff at the exact moment a unit was vacant-in-practice.

    Owner-managed

    Works only when the owner is set up, reachable, and paying attention.

    Community-managed

    Keeps alert visibility, location, and history at the property level.

    One coordinated standard for leaks

    For condominiums, the question is not whether some owners are protected. It is whether the building has one consistent standard for finding leaks, alerting the right people, documenting the event, and supporting response when contact records are imperfect.

    Leaks do not wait for paperwork.

    In this case, the owner record was in transition. The unit protection stayed active.

    How Halo works

    The catch at Sailmaker Place wasn't luck. Halo connects moisture sensors, water-flow meters, and automatic shut-off valves into a single coordinated system. It watches leak-prone areas around the clock, alerts owners and staff the moment something's wrong, and can cut the water before a small event becomes a major loss.

    Four steps: sensors monitor leak-prone areas, owners and staff get fast notifications, automatic shut-off valves stop water flow, and activity is visible in one coordinated system with 24/7 support
    Halo system: sensors, water meter, automatic shut-off valve, mobile alerts, and a building overview dashboard
