Structural Drying and Dehumidification

What is structural drying?

Structural drying removes water from the building itself: drywall, framing, subfloor, concrete and cabinetry. It follows water extraction and uses dehumidifiers, air movers and sometimes targeted heat to pull moisture out of materials until they reach a dry goal. The IICRC S500 standard calls this "applied structural drying," and it is the part of the job adjusters review most closely.

Why dry air outside isn't enough

East Valley air is dry most of the year, so it's tempting to open the windows and wait. That works for wet surfaces you can see. It doesn't work for water soaked into the bottom of drywall, trapped under vinyl plank or sitting under a kitchen toe-kick. Those areas need moving air and low humidity right at the wet material, or they stay damp for weeks. Summer monsoon humidity makes passive drying even slower.

How we dry your home

1. Set a dry goal. We take readings from unaffected materials in your home to learn what "dry" means for your drywall, wood and concrete.
2. Map wet areas. Moisture meters and thermal imaging mark exactly where water went.
3. Open trapped spaces. Baseboards come off, small holes go in behind them, and toe-kicks may be removed so air reaches wall cavities and under-cabinet spaces.
4. Place equipment. Dehumidifiers pull water vapor from the air. Air movers sweep the wet surfaces. Specialty mats or panels dry hardwood and concrete when needed.
5. Monitor daily. We check every marked point each day, adjust equipment, and record the readings.
6. Confirm dry. Equipment comes out when each material matches its dry goal, not when a set number of days passes.

The equipment

• Low-grain refrigerant (LGR) dehumidifiers that keep pulling water from air even as it gets drier
• Desiccant dehumidifiers for large or cold spaces and dense materials
• High-velocity air movers to speed evaporation from wet surfaces
• Floor and wall drying systems that push dry air into hardwood or wall cavities without tearing them out
• Moisture meters and thermo-hygrometers to measure progress

Drying classes and why they matter

The amount of wet material decides how much equipment the job needs. A small leak that wet less than 5% of a room's surfaces needs far less drying power than a room where water wicked up the walls and soaked the carpet. Dense materials such as hardwood and concrete hold water deep inside and need slower, targeted drying. Our guide to water damage categories and classes explains the ratings.

Saving materials instead of tearing them out

Good drying saves money. Drywall soaked by clean water can usually be dried in place if drying starts within a day or two. Cabinets can often be saved by removing toe-kicks and drying underneath. Hardwood floors that have cupped slightly may flatten as they dry. We remove materials only when they're contaminated, structurally damaged or can't reach a dry goal in a reasonable time.

After drying, our water damage repair crew replaces baseboards, patches drywall and finishes the room.

Documentation for your claim

Each day's readings, photos and equipment counts go into a drying log. That log shows your adjuster why each piece of equipment was needed and when the structure reached dry. It is the main record insurers use to approve drying charges.
