Burst Bathroom Flexi Hose Causing Multi-Level Water Damage in Oyster Bay NSW

Incident Overview

High Demand Restoration was engaged to carry out make-safe and drying works at a residential property in Oyster Bay following a burst flexi hose in the upstairs bathroom. The water leak is believed to have run for several hours, resulting in flooding to the upstairs carpeted areas and water migration through the subfloor into the ceilings and living spaces below.

By the time of attendance, initial water extraction had already been completed, and some drying equipment was in place. Our focus was to assess the full extent of the damage and implement a structured drying plan to address both visible and hidden moisture.

Inspection and Findings

Upon inspection, the upstairs carpets were found to be wet across the hallway, landing, and adjacent bedroom areas. Once lifted, the subfloor beneath was identified as heavily saturated, with elevated moisture levels throughout.

Downstairs, while the carpets had dried, significant water damage was present in the ceilings across the kitchen, dining, and laundry areas. Moisture testing confirmed elevated readings in multiple ceiling sections, along with increased moisture levels in the laundry wall.

The extent of water travel from the upper level to the lower ceiling cavities highlighted the need for targeted drying within concealed structural areas.

Remediation Works

To address the moisture within the ceiling cavities without causing unnecessary damage, High Demand Restoration implemented a non-invasive drying approach. Air movers were ducted into existing ceiling openings, including downlight and fixture points, to increase airflow within the cavities. Additional airflow was directed across affected wall and cabinetry areas, and a dehumidifier was installed to control internal humidity and support the drying process.

Upstairs, the carpets were lifted and the wet underlay removed to allow direct access to the saturated subfloor. This step was essential to ensure effective drying and prevent long-term moisture retention. Drying equipment, including air movers and a dehumidifier, was installed to accelerate moisture removal from the affected areas.

During follow-up visits, moisture levels were closely monitored. As areas began to dry, equipment was progressively adjusted and reduced. However, persistent moisture was identified within the lower section of the wall between the living room and laundry, requiring further attention.

With approval, a controlled opening of the affected wall section was carried out to allow access to the internal cavity. Moisture readings confirmed elevated levels within the timber framing at the base of the wall. An air mover was then ducted directly into the wall cavity to target the trapped moisture and continue the drying process.

Why This Matters

Water damage from plumbing failures can extend beyond visible surfaces, often affecting internal structural components such as subfloors, ceilings, and wall cavities. Without proper drying, this hidden moisture can lead to long-term structural issues and increase the risk of mould growth. A combination of non-invasive and controlled invasive drying methods ensures that all affected areas are properly addressed.

The Result

Through a staged drying approach and ongoing monitoring, the affected areas, including carpets, ceilings, and subfloor sections, were successfully dried and stabilised. Remaining moisture within concealed wall areas was identified and addressed through targeted structural drying, ensuring a thorough and controlled restoration process.
