Structural drying and dehumidification in Las Vegas

Structural drying is done when the meters say so, which is why we read walls, subfloors and framing every visit instead of pulling the gear on a set day.

Dry air is not the same as a dry wall

Las Vegas is the driest major metro in the continental United States, according to the National Weather Service. That helps surfaces dry. It does not dry a wall cavity, the underside of a cabinet or a slab, which hold water behind a dry looking face. Drying those takes air movement into the cavity and dehumidifiers pulling water out of the room air.

How the drying is measured

On day one we map moisture in every wet room and pick a dry reference from an unaffected wall. Each visit we read the same spots. The job is done when wet materials match the reference. That record goes to you and your insurer.

Monsoon humidity

The NWS describes the monsoon push of moisture in July and August that brings higher than average humidity. Drying slows when the outdoor air is damp, so summer storm jobs lean harder on dehumidifiers and closed rooms.

The first hour

Clock	Action	Why
0 min	Get people out of the water	Do not walk or drive through moving water. Ready.gov says six inches of moving water can knock you down and one foot can sweep a car away.
2 min	Stop the source if you safely can	For a pipe, close the main shutoff. LVVWD says it is usually in the front yard near the sewer riser cap, in the garage or at the home's manifold.
5 min	Keep away from wet power	Ready.gov says not to touch electrical equipment that is wet or while you stand in water. Leave the breaker panel alone if the floor around it is wet.
10 min	Call or text (702) 602-9420	Tell us where the water came from, which rooms are wet and whether it came in from outside. That decides the crew and the gear.
15 min	Photograph everything before it moves	Wide shots of each room, close shots of the water line on walls, and the source. Your insurer will ask for these.
30 min	Lift and separate	Move rugs, boxes and furniture off wet floors. Put foil or wood blocks under furniture legs that must stay.
45 min	Treat flood water as dirty	Floodwater can be contaminated, per Ready.gov. Wear gloves and boots. Keep children and pets out.
60 min	Start the 48 hour clock	EPA says to dry water damaged areas and items within 24 to 48 hours to prevent mold growth. Extraction and drying should start inside that window.

Structural Drying and Dehumidification questions

How long does structural drying take?

It depends on the materials and how long they were wet. We read them every visit and stop when they match a dry reference.

Can a fan and open windows dry my house?

They dry surfaces. Wall cavities, cabinets and slabs hold water behind dry looking faces and need air into the cavity and dehumidifiers.

Does the dry Las Vegas air help?

It helps surfaces. The NWS calls Las Vegas the driest major metro in the continental US, but hidden water still needs targeted drying.

Why is drying slower in summer storms?

The NWS says the monsoon brings higher than average humidity in July and August, which slows evaporation.

What is a dry reference?

A reading from an unaffected wall or floor of the same material. Wet materials are dry when they match it.

Will the equipment be loud?

Air movers and dehumidifiers make steady noise. We place them to keep bedrooms usable where we can.

Can I turn the gear off at night?

Please leave it running. Turning it off adds days to the job.

Do I need to run my AC?

Yes, keep the home at a normal temperature. We will tell you if a room should stay closed.

Why do you read the same spots every day?

So the record shows the drying trend for each wet spot, which is what an adjuster looks for.

How do I set up drying?

Call or text (702) 602-9420. Drying usually follows extraction on the same visit.
