Structural drying is the part of a water loss that happens after the visible water is gone. It decides whether framing, subfloor and drywall return to normal or hold moisture for weeks.
Why surface water is only half the loss
A 2015 Minnehaha Creek Watershed District study found that five of the 16 Lake Zumbra properties hit in 2014 had water above the lowest opening, which means walls and framing were involved and not only the floor. When water climbs into a wall, wicking carries it higher than the stain, and only meters or a thermal camera show how far.
- Low-grain dehumidifiers pull moisture out of the air
- Air movers push dry air across floors and wall bottoms
- Heat or desiccant units handle dense or cold materials
How drying classes work
The IICRC S500 groups losses into classes by how much moisture materials absorbed. Class 1 and 2 jobs involve little or moderate wet material, while Class 4 means dense items such as hardwood, plaster or concrete that hold water deeply and need slower, targeted drying in Victoria homes just as anywhere.
Proof that drying is finished
Readings are taken on the same spots at each visit and compared with a dry sample from an unaffected area. Equipment comes off only when every wet material meets that target, and the log then goes into the claim file for the adjuster and the rebuild. See water extraction for what comes before drying and basement flooding cleanup for lower-level losses.
