Structural drying for Miami homes and condos

Structural drying removes the water that soaked into drywall, framing, cabinets and floors after the standing water is gone. EPA says drying usually takes several days to weeks, and that materials such as walls and flooring should read 15% or less on a moisture meter before they are refinished. (US EPA)

Structural drying is one part of our Miami water damage restoration: one call connects you with a local restoration crew that serves your address. Not sure where to start? Read how drying days show up on a restoration estimate.

How a structural drying job runs, from first readings to repairs

Structural drying starts once the standing water is out and ends when the materials are dry enough for repairs. The industry standard for this work, ANSI/IICRC S500, has the restorer set dry standards and drying goals on the first visit, so ask what dry standard the crew set before drying starts. If you are weighing renting fans and a dehumidifier yourself against having a crew run the drying, ask what the crew will measure and how you will both know the building is dry. (IICRC)

What to check first

• Starting moisture readings in each wet room.
• How far the water wicked: up the drywall, under cabinets and flooring, and into the slab.
• Damage that was there before this loss, so it is not mistaken for new damage.
• Which materials can be dried in place and which have to come out.

The work, in order

1. Assessment: the checks above, and the dry standard the materials have to reach.
2. Drying plan: what comes out, which cabinets and built-ins are opened or removed, and whether the house is closed up and dehumidified. Ask to see the plan before work starts.
3. Monitoring: ask how often the crew will take readings until every material reaches the dry standard, and for copies.
4. Completion: drying ends when the readings meet the dry standard, including the slab before new flooring goes down, not when the surface looks dry. (US EPA)
5. Handoff to repairs: ask for the final readings and pass them to whoever rebuilds.

Separate jobs to plan for

• Water removal, if standing water is still there: it comes before drying.
• Repairs: drywall, baseboards, cabinets and flooring go back once the readings say dry. Ask whether that is a separate contract.
• Mold remediation, if mold has already grown on materials that stayed wet.
• Checking and cleaning the air conditioning system, if it took on water.

Why the building still needs drying after the water is gone

EPA’s flood guidance is to dry the house and everything in it completely, and not to seal wall cavities or paint surfaces that were wet until the materials are completely dry inside. (US EPA)

Wet materials left behind are where mold starts. EPA notes that mold can grow on wood, drywall, carpet and furniture that remain wet for more than 24 hours after flooding. (US EPA)

Drying in Miami’s humid air

Open windows do not always help here. EPA notes that very humid, warm outdoor air can slow drying down, and suggests closing outside doors and windows and using fans, dehumidifiers, air conditioners or heaters instead when power is available. (US EPA)

For the house as a whole, EPA recommends keeping indoor relative humidity below 60 percent, ideally between 30 and 50 percent, which a small humidity meter can measure. (US EPA)

How dryness is measured

Dry is a reading, not a look. EPA suggests a moisture meter and gives 15% or less as the point at which materials such as walls, cabinets and flooring are ready for refinishing. (US EPA)

Opening up hidden spaces so they can dry

Water hides behind cabinet doors, under drawers and inside built-ins. EPA’s drying advice is to open inside doors and cabinets and remove drawers, shelves and built-in furniture such as cabinets so hidden surfaces can dry, then run fans and dehumidifiers through the house if power is available. Ask the crew which built-ins it plans to remove and whether they can go back in afterwards. (US EPA)

Is the concrete slab dry?

EPA says to be sure a concrete slab is dry before replacing the flooring over it, to prevent mold growth, and describes a simple check: (US EPA)

1. Tape the edges of a clear piece of plastic sheeting to the slab.
2. Wait about 16 hours.
3. If moisture is visible on the plastic, the slab is still too wet for new flooring.

Your air conditioning during drying

If the HVAC system took on water, CDC advises having it checked and cleaned by a professional experienced in mold cleanup before turning it on, because a contaminated system spreads mold through the house. (CDC)
