Structural Drying Services
Structural drying is the science half of restoration: removing bound moisture from framing, subfloor, plaster and concrete after the free water is gone. It is not a matter of putting fans in a room — equipment counts are calculated from cubic volume, class of loss and material type, then adjusted daily against psychrometric readings until the building matches its own unaffected baseline.
Common causes we see
- Any water loss where materials remain wet after extraction
- Losses where a previous contractor left before dry standard was reached
- Water trapped in wall cavities, under flooring or inside a floor system
- High ambient humidity preventing natural drying after an event
Signs you need Structural Drying now
- Meters still reading above baseline days after the water was removed
- Condensation forming on windows or cool surfaces in the affected area
- A musty smell that appears in the afternoon and fades overnight
- Flooring or trim that continues to move after the surface looks dry
Situations we handle every week
- The last company ran fans for a week and never took a reading
- You need proof of dry standard before a rebuild contractor will start
- The room looks fine but the smell keeps coming back
What happens if it is left alone
- Materials left above 16% moisture content support mold colonisation regardless of how dry the surface feels
- Wood that dries unevenly warps, cups and splits as it finally equalises months later
- Trapped cavity moisture drives paint and adhesive failure long after the job is closed out
- Without documented dry standard, a carrier can attribute later mold to incomplete mitigation
How we handle structural drying
- 1Establish baselines and class the lossUnaffected areas of the same materials are read first. Without a baseline there is no defensible endpoint. The loss is then classed 1 to 4 by how much porous material is wet.
- 2Calculate the equipment loadDehumidifier capacity is calculated from cubic volume and class, and air movers from wall linear footage — not from how many units happen to be on the truck.
- 3Create a controlled drying chamberWhere possible the affected area is isolated with containment so we are conditioning a defined volume instead of the whole building.
- 4Daily psychrometric monitoringTemperature, relative humidity, GPP and material moisture content are recorded daily. Equipment is moved, added or removed based on what the numbers show.
- 5Verify and document dry standardDrying ends when affected materials match unaffected baselines across consecutive readings, and you receive the full log as the release document.
What's included
- Baseline and affected-material moisture mapping
- Calculated LGR dehumidification and air-mover placement
- Containment to create an efficient drying chamber
- Specialty drying systems for cavities, floors and hardwood
- Daily psychrometric logs with photos
- Written dry-standard verification report
How this differs from similar services
Structural Drying vs Emergency Water Extraction
Extraction removes free water mechanically in hours. Structural drying removes bound moisture from materials over days. Extraction always comes first.
Structural Drying vs Dehumidification Services
Dehumidification is one tool inside structural drying. As a standalone service it addresses ongoing humidity rather than a specific wet building.
Read before you decide
Structural Drying — frequently asked
Three to five days for most single-room losses, seven to ten where hardwood, plaster or multiple rooms are involved. It is decided by readings, not by a schedule — the equipment leaves when the numbers say it can.

Water Mitigation
Mitigation is the insurance term for stopping the damage from getting worse, and it is a distinct phase with its own scope, pricing and documentation standard. It ends the day the building meets dry standard — reconstruction is a separate agreement. Carriers evaluate mitigation on how quickly it started and how well it was recorded, which is why our documentation begins on the first visit.
Dehumidification Services
Dehumidification is what actually removes water from a building — air movers only push it into the air. This page covers dehumidification as a standalone service: chronic indoor humidity, damp enclosed spaces, post-loss moisture control after another contractor has left, and temporary humidity management during construction or storage.
Hardwood Floor Drying
Cupped hardwood is not automatically ruined. Wood cups because the underside is wetter than the top, and if the moisture is pulled out through the boards quickly enough the planks often flatten back out as they equalise. That requires negative-pressure mat systems that draw moisture up through the floor — ordinary air movers blowing across the surface do nothing for a wet subfloor.
Moisture Detection
Moisture detection is diagnostic work: finding water you cannot see and proving how far it has spread, without demolishing the building to look. Thermal imaging shows temperature anomalies, meters confirm whether those anomalies are actually wet, and the combination produces a moisture map you can act on — or use to show an adjuster exactly what is affected.
