How long does structural drying take in a Wichita building?
It takes as long as the readings say, and the answer depends on the materials and how much water reached them. Drying is finished when the framing, subfloor and cavities read at the dry level, not after a set number of days.
A wet surface can look dry long before the framing behind it is. Wood holds water in its core, and a wall cavity can stay damp while the drywall face is dry to the touch. For that reason the crew takes readings in the framing itself, at the bottom plates and along the subfloor.
The crew explains the progress at each visit. You will be told which materials are reading closer to dry, which are slower, and what they are doing about the slow ones. A drying job should end with a log that shows the readings and the date each material reached its dry level.
Why do the air movers and dehumidifiers stay in the house after the room looks dry?
Because the moisture is in the materials, not on the surface. Equipment is removed when the readings in the framing and subfloor show the materials are dry, and leaving it in place for longer is the only way to be sure the water is gone.
Taking the equipment out early is one of the most common reasons a building is closed up over moisture. The room looks finished, and the wall is repaired, but the framing behind it still holds water. The repair then traps that water inside the wall, where it can cause damage out of sight.
The crew will explain why equipment is still needed, and it will tell you when it can come out. If you want it removed sooner, ask what the readings show and what the risk would be before you decide.
What does a drying log need to show?
Each visit's date and time, the readings in each material and in the air, the equipment in each room, any openings made and the dry level for each material. The log is the record your insurer and the repair contractor will use.
A log with only a line saying the room is dry does not show what was done. A useful log has numbers that can be compared from one visit to the next, so the trend is visible. It also shows which materials were removed and which were kept, and why.
Keep a copy of every log with the photographs. The repair crew will need the readings to decide when the framing is ready to be closed, and the insurer will need them to see how the loss was handled.
What can go wrong with drying in a house?
Equipment can be left running in the wrong place, openings can be closed too early, and a material can be missed in the readings. Each of these leaves moisture in the building. The crew checks its own work at every visit and records what it finds.
Moisture that is moved from one room into another can wet a room that was already dry. Doors and openings are arranged to keep the flow of air moving toward the equipment, and the crew checks the adjoining rooms on each visit.
Equipment itself can fail or be turned off by a power issue. The crew checks it at each visit, and it notes any gap in the drying in the log, so you know when the work was interrupted.
Does drying a building affect the comfort or the safety of the household?
It can. Air movers are loud, and dehumidifiers change the temperature and humidity in a room. Cords and hoses cross floors, and openings in walls create trip hazards. The crew arranges the equipment so people can still use the house safely.
Ask the crew to show you where the cords run and where the hoses are routed, and to keep them clear of walkways. Children and pets should be kept away from the openings and from the equipment while it is running.
If someone in the household is sensitive to noise or to a change in humidity, tell the phone team before the crew arrives. The equipment can often be placed so it is less disruptive, and the crew will explain what it is doing and why.
