Structural Drying and Dehumidification
Once the standing water's gone, the hard part is the water you can't see, inside your drywall, subfloor and framing. Structural drying is the equipment and the daily checks that get those materials properly dry, instead of leaving them to dry on their own and hoping. Call (888) 596-0163, and we'll connect you with a local drying specialist.

Drying to a measured standard instead of a guess
The IICRC S500 sorts drying jobs into four classes, depending on how much water got in and how hard the materials are to dry. Class 1 is a small area that didn't soak much up. Class 2 is a whole room, with water wicking up the walls. Class 3 is when it came from above and soaked the walls and ceiling. Class 4 is for dense things like hardwood, plaster and concrete. Readings from a dry part of your home set the target, and the job's finished when the wet areas match it.
- Low grain refrigerant (LGR) dehumidifiers, which keep pulling water out even once the air is fairly dry
- Desiccant dehumidifiers for cold rooms and dense materials like hardwood and concrete
- Air movers, angled along the walls to keep dry air flowing over wet surfaces
- Injection drying, which pushes dry air into wall cavities and under hardwood through small holes
- Meters that record humidity, temperature and the moisture in your walls and floors on every visit
How a structural drying job runs
-
Take baseline readings
First they measure. Moisture meters and a thermal camera show what's wet, and readings from a dry part of your home become the target. It all goes on a moisture map for the job file.
-
Set up the drying system
The equipment is sized to the room and how wet it is. Baseboards may come off, and a few small holes may go in low on the walls so dry air can get inside.
-
Monitor daily
Readings are taken and written down every visit. Equipment gets moved as areas dry, and they check that the dehumidifiers are still pulling water out of the air.
-
Confirm dry standard
The equipment only leaves when the wet areas read the same as the dry ones. That record is what your adjuster looks at before approving the repairs.
Structural drying questions
How long does structural drying take?
Most homes take three to five days once the water's out. Hardwood, plaster, concrete and contaminated water jobs can take longer. The moisture readings decide when it's done, not the calendar.
Can I just open the windows and run fans?
Fans move air, but they don't take the water out of it. In humid weather, open windows can even bring more moisture in. Dehumidifiers are what actually remove the water, and moisture meters show you if it's working.
Why are holes being drilled in my walls?
Small holes near the bottom of a wall, usually where the baseboard will cover them, let injection drying push dry air inside. Interior walls without insulation can often be dried this way without cutting out any drywall. The holes get patched during repairs.
Why is my hardwood floor cupping?
Cupping happens when the bottom of the boards takes on more water than the top, so the edges rise. Slow, controlled drying with floor mats and dehumidifiers often lets the boards settle back. If the floor's sanded flat before it's fully dry, it can crown later as the bottom shrinks.
Why does the equipment have to run overnight?
Drying has to be continuous. Switching air movers and dehumidifiers off at night lets the humidity climb back up, and everything stops drying. Some insurers pay back the power the equipment uses, so it's worth asking your adjuster.
