Structural Drying & Dehumidification

Professional Structural Drying & Dehumidification

Structural drying is the science of removing moisture from building materials to prevent long-term damage and mold growth. Unlike simple water extraction, structural drying addresses moisture absorbed into wood framing, subfloors, drywall, and concrete—materials that hold water for weeks without proper intervention.

IICRC S500 standards specify that structural materials must reach moisture content below 15% (or pre-loss levels) before reconstruction. Our technicians use psychrometric calculations to determine optimal equipment placement, airflow patterns, and dehumidification capacity. Daily monitoring with moisture meters verifies progress toward dry standard.

Our Structural Drying & Dehumidification Process

1. Document baseline moisture readings in all affected materials
2. Calculate required dehumidification capacity using psychrometric charts
3. Position air movers at 1 per 10-16 linear feet of wall
4. Set dehumidifiers to maintain 30-40% relative humidity
5. Create airflow patterns that move moisture toward equipment intake
6. Open wall cavities if moisture readings indicate trapped water
7. Take daily moisture readings at multiple checkpoints
8. Adjust equipment placement based on drying progression
9. Document dry standard achievement for insurance
10. Remove equipment only after 24-hour moisture stability

Equipment & Technology

• LGR (low grain refrigerant) dehumidifiers removing 30+ gallons/day
• Desiccant dehumidifiers for cold or low-humidity environments
• Centrifugal air movers (3,000+ CFM) directing airflow across wet surfaces
• Axial air movers for large open areas
• Injectidry systems forcing air into wall cavities
• Protimeter deep wall probes for internal moisture readings
• Thermo-hygrometers monitoring ambient conditions
• FLIR thermal cameras identifying cold (wet) spots

Pricing

Structural drying equipment runs $300-$600 per day for a typical 3-room setup. Most residential jobs run 3-5 days ($1,200-$3,000 total). Larger areas, concrete slabs, or cold environments requiring desiccant equipment cost more. Insurance covers drying as part of mitigation.

Timeline

Standard drywall and wood framing: 3-5 days. Concrete and masonry: 7-14 days. Cold or humid seasons extend timelines. Daily monitoring ensures efficient completion.

When You Need Structural Drying & Dehumidification

• After any water extraction to prevent mold growth
• Following burst pipes with water in wall cavities
• Post-flood when structural materials absorbed water
• After firefighting efforts soaked structure
• When humidity or moisture meters indicate elevated readings
• If musty odors develop after water incident
