WatchWhy Does Home Restoration Seem to Drag On?We have a separate guide for what you should do in the first day after a leak. You'll find it at the first 24 hours after water damage. This one is about the other side of the door: what a mitigation crew is doing during the first 48 hours, and why each step matters.
Water doesn't stop working when it stops flowing. It wicks up drywall, spreads under flooring and settles into insulation. The first two days are about getting ahead of it. Here's how CMDR Restoration, our mitigation partner (licensed by TDLR, RCO #1801), approaches that window.
What Happens When the Crew First Arrives?
Safety and source. Before anything else, the crew confirms the water is off and the source is stopped or isolated. They look for electrical hazards, sagging ceilings and slip risks. If a plumber is still needed, that gets coordinated right away.
Category check. Not all water is the same. Clean water from a supply line is handled differently than gray water from a washing machine or contaminated water from a sewer backup. The category drives how much gets removed and what protective gear is needed. Our guide on Category 3 water explains the differences.
Documentation starts. Photos of every affected room, before anything moves. That record matters for you and for the rebuild later.
How Does the Crew Figure Out How Far the Water Went?
Moisture mapping. Technicians use moisture meters and thermal cameras to trace where water traveled: under cabinets, behind baseboards, through the wall into the next room, down into the subfloor. They mark readings and sketch a map. It's very common for water to travel well beyond the visible stain.
This is also when they take a reading in a dry, unaffected area to use as the normal baseline.
What Gets Removed in the First Day?
The goal is to remove what can't be dried and anything that will feed mold if it stays. That often includes:
- Standing water, through extraction
- Wet carpet pad, and sometimes carpet
- Baseboards, to open the wall
- Drywall below the wet line, using flood cuts at or above the IICRC guidance of at least 18 inches above moisture (most crews cut at 2 feet)
- Wet insulation
- Swollen particleboard, like some cabinet toe kicks
Contents get moved, blocked up or packed out so they don't sit in water.
How Is the Drying System Set Up?
Air movers push air across wet surfaces to speed evaporation. Dehumidifiers pull that moisture out of the air. The crew places equipment based on the moisture map, not just on what looks wet, and may use plastic containment to create a tighter drying zone. Our structural drying guide goes deeper on how that works.
What Happens on Day Two?
Monitoring. The crew returns to take readings at the same marked spots. Are numbers going down? Is a wall stubborn? Equipment may get moved, added or removed based on what the readings say.
Adjustments. If a hidden area is still wet, like a cavity behind a cabinet or a corner of the subfloor, more material may need to be opened up. That decision comes from the meter, not a hunch.
Planning the rebuild. On a G3 Knows job, the rebuild team already has the photos, moisture logs and list of removed materials. That handoff is one of the biggest advantages of having mitigation and restoration under one roof.
Why Does This Window Matter So Much?
Mold needs moisture, warmth and food, and a wet house provides all three. Paper-faced drywall, insulation backing and wood framing are food. We won't quote you a magic number of hours, because every loss is different. What we can tell you is that the longer materials stay wet, the more likely they'll need to be replaced instead of dried. Fast, correct mitigation saves materials, time and stress.
When Should I Call?
As soon as the source is stopped and everyone is safe. Call CMDR and G3 at (945) 300-9018, or learn more on our water damage page.
Frequently Asked Questions
Will the crew finish in 48 hours?
Usually not. The first 48 hours set up the drying. The structure often takes several more days to reach normal readings.
Why did they remove drywall that looked fine?
Because the meter said it was wet. Water travels farther than stains show.
Do I need to be home during monitoring visits?
Someone needs to let the crew in. We'll coordinate times with you.
Can the rebuild start before drying is done?
No. Building over wet materials invites mold and do-overs.
