24/7 Emergency Response in Hobart
When water intrudes into a Hobart property, the visible puddle is just the surface of the issue. The real threat to the integrity of local homes, from Federation-era weatherboards in New Town to the historic sandstone cottages of Battery Point, is the persistent damp that seeps into the structure. Our work is dedicated to removing this hidden saturation from deep within building materials.
We are an IICRC-certified firm based in Hobart, and our technicians are trained to manage the unique challenges of drying buildings in Tasmania’s cool, damp climate. Whether the damage is from a burst water pipe in a modern Kingston apartment or widespread water ingress after a major weather event like the May 2018 floods that inundated South Hobart and Sandy Bay, the science is the same. Water migrates through porous materials, and our climate fosters ideal conditions for mould and rot, often in under 48 hours. Our role is to intervene with a structured, scientific drying process that preserves your property’s value and structural health.
What is Structural Drying in a Temperate Maritime Climate?
Structural drying is the application of psychrometric principles to methodically extract moisture from building materials and concealed spaces. In a city like Hobart, where the cool air and proximity to the Derwent Estuary create consistently high relative humidity, simply opening windows or using domestic fans is often ineffective. This approach can even worsen the problem by introducing more moisture-laden air, a phenomenon known as secondary damage.
Professional structural drying targets the water absorbed deep within timber sub-floors, concrete foundations, plaster walls, and insulation. Ignoring this “bound water” is why we see persistent musty odours in post-war homes in Glenorchy and cupping or crowning of Tasmanian Oak floorboards in Bellerive weeks after a leak. The objective is to return every affected material to its established pre-loss moisture content, or ‘dry standard’, ensuring long-term stability and preventing future mould outbreaks.
Our Documented Structural Drying Process
We strictly follow the AS/NZS S500 Standard for professional water damage restoration. This framework ensures our process is methodical, transparent, and provides the detailed documentation required for Tasmanian insurance assessors.
Moisture Detection & Mapping
Our initial inspection employs FLIR thermal imaging cameras and non-invasive Tramex moisture meters. This technology allows us to map the complete path of water migration, often revealing how a simple laundry leak in a West Hobart townhouse has travelled through floor systems and down wall cavities to affect multiple levels.
Drying Equipment Deployment
We strategically deploy specialised equipment, including Phoenix and Dri-Eaz Low-Grain Refrigerant (LGR) dehumidifiers. These units are engineered for high performance in the lower ambient temperatures common in Tasmania. They work in tandem with high-velocity air movers to create a controlled drying environment, accelerating evaporation from saturated materials like brickwork and timber frames.
Subfloor & Cavity Drying
For the under-house "crawl spaces" typical of many Tasmanian homes, particularly in areas like Lenah Valley, we direct focused airflow to dry out damp soil, footings, and floor joists. In properties with solid walls or limited cavities, we utilise injecti-dry systems. These force dry, often heated, air into wall cavities, behind skirting boards, and under cabinetry to target moisture that would otherwise remain trapped and lead to decay.
Continuous Monitoring
An IICRC-certified technician monitors the drying project daily. We record temperature, relative humidity, and the specific moisture content of materials. This data-driven methodology allows us to make precise adjustments to equipment placement and configuration, ensuring maximum drying efficiency and preventing over-drying, which can damage sensitive materials.
Verification & Completion
A project is formally complete only when our calibrated moisture meters confirm that affected materials have returned to their established dry standard. We provide clients and their insurers with a comprehensive final report, including all drying logs and moisture maps, to verify the structure is certifiably dry, stable, and safe.
Specialised Structural Drying for Hobart Homes
We utilise specific drying methodologies tailored to the common building materials and architectural styles found across the greater Hobart area.
Concrete Slab Drying
A significant number of properties in newer developments like Glebe Hill and homes in Rokeby are constructed on concrete slab foundations. Following an internal flood or burst pipe, these slabs can absorb and retain a large volume of water. We use penetrating concrete moisture meters to determine saturation levels, then deploy LGR dehumidifiers to drastically reduce the moisture content of the air directly above the slab. This creates a pressure differential that compels the concrete to release its trapped water. This is an essential step before reinstalling floor coverings, which would otherwise be compromised by residual moisture.
Gyprock & Wall Cavity Drying
Plasterboard walls in homes from Howrah to Margate can quickly draw up water through capillary action. If we are called in promptly, our technicians can often dry plaster walls in place using targeted airflow and cavity drying systems, avoiding the significant cost and disruption of demolition and replacement. Our initial moisture assessment determines whether the wall’s integrity is intact or if replacement is the only viable option.
Ceiling & Roof Cavity Drying
Winter storms and blocked gutters frequently cause roof leaks and sub-floor dampness. In the attic, water saturates insulation and plaster ceilings, creating a serious collapse hazard and a perfect breeding ground for mould. Beneath the floor, persistent damp from poor drainage affects bearers and joists, leading to rot. We implement specialised cavity drying techniques to remove moisture from these hidden areas, often saving ceilings and preventing widespread decay in the home’s primary structural supports. Following the intense rainfall of the May 2018 storm, our team addressed severe sub-floor saturation in numerous properties across Sandy Bay and Blackmans Bay.
Insulation and Wall Frame Drying
Water trapped within wall insulation not only nullifies its thermal rating (R-value) but also becomes a reservoir for mould growth. In the many timber-framed homes across Hobart, this moisture directly leads to wood rot in studs and plates. Our process involves injecting heated, dehumidified air into wall cavities to thoroughly dry both the timber frame and the insulation. This is a critical procedure for preserving the home’s structural integrity and ensuring healthy indoor air quality.

Frequently Asked Questions About Structural Drying in Hobart
Structural drying is a scientific process that uses specialised equipment like LGR dehumidifiers and high-velocity air movers to extract absorbed moisture from building materials such as concrete, timber, brick, and plaster. The goal is to prevent long-term damage like mould, timber rot, and compromised structural integrity.
For a standard Category 1 water intrusion (like a clean water pipe burst), the drying process typically takes 3 to 5 days. More complex situations involving significant saturation, contaminated water, or floodwaters from sources like the Hobart Rivulet, may require a longer period.
Hobart’s cool, temperate climate and high average humidity prevent effective natural evaporation. Without professional-grade dehumidification to manipulate the air, moisture will remain trapped within the structure, leading to mould growth (which can begin in 24-48 hours) and progressive material decay.
We use a combination of high-velocity air movers to promote evaporation, LGR (Low-Grain Refrigerant) dehumidifiers specifically designed for cooler Tasmanian conditions, FLIR thermal imaging cameras to track moisture, and calibrated penetrating and non-penetrating moisture meters to manage and document the entire drying process.
Delay allows moisture to penetrate deeper into building materials. This causes timber frames to warp, Tasmanian Oak floors to cup or buckle, and plasterboard to swell and lose its structural integrity. A delay significantly increases the probability of widespread mould contamination, which poses health risks and necessitates a far more complex and costly remediation project.
