Fast action protects your structure, indoor air quality, and your budget
Water damage moves quickly. In Caldwell homes—especially during winter freezes, sudden thaws, and heavy rain events—moisture can migrate behind baseboards, under flooring, and into wall cavities long before it’s visible. The first 24–48 hours are the difference between a controlled dry-out and a much bigger repair and mold-remediation project. This guide breaks down what to do right away, what not to do, and when to call an IICRC-certified team like Apex Restoration for professional water damage restoration.
Why the “first 24–48 hours” window matters
Most water damage isn’t just “wet carpet.” Water spreads through porous materials (drywall, insulation, padding, wood) and can remain trapped where you can’t see it. If the affected area isn’t dried thoroughly, indoor humidity stays elevated and surfaces remain damp—conditions that increase the risk of mold growth and material deterioration. The CDC notes that if a home cannot be completely dried out within 24–48 hours after flooding, mold is likely. (cdc.gov)
Even when you don’t see standing water, you can still have moisture locked under laminate, behind cabinets, or inside ceiling cavities. That’s why professional water damage restoration focuses on measuring moisture and controlling evaporation—not just “drying what looks wet.”
Step-by-step: What to do immediately after water damage
1) Stop the source (if it’s safe)
If the water is from plumbing (burst pipe, failed supply line, overflowing fixture), shut off the water supply. If water is near electrical outlets or you’re standing in water, don’t touch breakers or appliances—electrical hazards are a real risk after flooding. The CDC cautions to never use electrical tools or appliances while standing in water. (cdc.gov)
2) Protect your health first (PPE matters)
If you’re cleaning up minor water intrusion, wear gloves and eye protection. If you see mold, smell musty odors, or are removing damaged drywall or insulation, use at least a NIOSH-approved N95 respirator. The CDC recommends an N95 at minimum for mold cleanup and notes some people (asthma, COPD, immune suppression) should not participate in cleanup. (cdc.gov)
3) Document damage for insurance (before you move too much)
Take wide and close-up photos, video walkthroughs, and notes (where it started, when you discovered it, what rooms were affected). FEMA recommends keeping receipts and retaining material samples when appropriate, and beginning cleanup/documentation promptly after severe weather events. (fema.gov)
4) Remove standing water the right way
If an electrician has verified it’s safe to restore power, the CDC suggests using equipment like a wet-dry shop vac or a pump to remove standing water, plus fans and dehumidifiers to reduce moisture. Place fans to exhaust air outward to reduce spreading contaminants. (cdc.gov)
5) Start drying—but don’t trap moisture
Open windows when weather permits, run dehumidifiers, and avoid sealing wet areas. Don’t paint or caulk over damp materials—EPA specifically advises against painting/caulking moldy surfaces. (epa.gov)
What NOT to do (common mistakes that make damage worse)
Don’t run your HVAC if it was flooded. The CDC warns that turning on a mold-contaminated HVAC system can spread mold throughout the home; it should be checked and cleaned by a professional experienced in mold cleanup. (cdc.gov)
Don’t keep saturated porous materials “to see if they dry.” EPA notes that absorbent materials (like carpet and ceiling tiles) may need to be discarded if they become moldy because mold can penetrate porous spaces and be difficult to remove completely. (epa.gov)
Don’t mix cleaners. EPA warns not to mix cleaning products or add bleach to other chemicals. (epa.gov)
Don’t use generators indoors or near openings. The CDC warns against operating gasoline-powered generators in enclosed/partially enclosed areas or near doors/windows/vents and recommends keeping them at least 20 feet away to prevent carbon monoxide poisoning. (cdc.gov)
When to call a professional water damage restoration team
Some water damage is manageable with careful cleanup. Many situations are not—especially when moisture is hidden, contamination is possible, or building materials require controlled drying. It’s time to call a certified restoration contractor if:
• Water reached drywall, insulation, or subflooring (hidden saturation is likely).
• You see staining, bubbling paint, warping, or swelling on walls/floors.
• The home can’t be fully dried within 24–48 hours (mold risk rises). (cdc.gov)
• There’s a musty odor or you’ve had repeated leaks in the same area.
• The water source may be contaminated (backups, outdoor flooding, unknown source).
Apex Restoration serves Caldwell and the Treasure Valley with IICRC-certified technicians and a rapid emergency response. If you’re unsure, a professional moisture assessment can prevent unnecessary demolition—or catch hidden damage before it becomes a bigger problem.
Quick “Did you know?” facts
Mold can follow fast if a home can’t dry out quickly
If your home can’t be completely dried (including rugs and furniture) within 24–48 hours after flooding, mold is likely. (cdc.gov)
Porous items can be impossible to fully “clean” once moldy
EPA notes that absorbent/porous materials like ceiling tiles and carpet may need to be thrown away if moldy because mold can grow within crevices and be difficult to remove completely. (epa.gov)
An N95 respirator is a baseline for mold cleanup
CDC recommends at least an N95 respirator, plus gloves and goggles, when cleaning mold. (cdc.gov)
At-a-glance table: DIY cleanup vs. professional restoration
| Situation | DIY may be okay when… | Call a pro when… |
|---|---|---|
| Small sink overflow on tile | No seepage under cabinets; fully dried quickly | Water entered toe-kicks, walls, or seams; swelling/odor appears |
| Wet carpet from a minor leak | Leak stopped fast; padding not saturated; dehumidification started immediately | Padding soaked; water reached baseboards; you can’t dry it within 24–48 hours (cdc.gov) |
| Storm/flood water in basement | Rare; only if minimal intrusion and confirmed clean source | Contamination possible; electrical risk; structural materials affected |
Local angle: Caldwell-specific risk factors to watch
Caldwell properties commonly deal with water damage from:
• Freeze-related pipe breaks (garages, exterior walls, crawl spaces).
• Ice dams and roof leaks that soak attic insulation and ceiling drywall.
• Irrigation line failures in spring/summer that saturate foundations and basements.
• Crawl space moisture that leads to odors, wood moisture, and long-term air quality issues.
If you’re in Caldwell and the damage happened overnight or while you were away, it’s especially important to get a professional moisture inspection—hidden saturation is more likely when water sits undisturbed.

FAQ: Water damage restoration in Caldwell, ID
How fast can mold start after water damage?
If a home can’t be completely dried out within 24–48 hours after flooding, mold is likely. (cdc.gov)
Should I run fans and dehumidifiers after a leak?
Yes, drying quickly is important. CDC guidance includes using fans and dehumidifiers to remove excess moisture and suggests positioning fans to blow air outward to avoid spreading contaminants. (cdc.gov)
Can I just clean mold off carpet and keep it?
Sometimes carpet and other porous materials need to be discarded if they become moldy, because mold can grow within porous spaces and be difficult or impossible to remove completely. (epa.gov)
Is it safe to stay in the home while mold is being cleaned?
It depends on the extent of damage and your health. CDC guidance says people with asthma, COPD, or immune compromise should not stay in a moldy home or be present while it’s being cleaned. (cdc.gov)
What should I document for an insurance claim?
Photograph damage, keep receipts, and document what happened and when. FEMA also recommends retaining samples of damaged materials when appropriate and consulting your insurer/adjuster before signing certain agreements. (fema.gov)
Glossary (plain-English restoration terms)
Dehumidification
Removing moisture from the air so wet materials can dry faster and indoor humidity doesn’t stay high.
Porous / absorbent materials
Materials like drywall, carpet, padding, and insulation that soak up water. They can hold moisture and contaminants deep inside.
HEPA vacuuming
Using a high-efficiency particulate air (HEPA) vacuum to capture very small particles during final cleanup after contaminated materials are removed and areas are dry. EPA notes HEPA vacuums are recommended for final cleanup of remediation areas. (epa.gov)
PPE (Personal Protective Equipment)
Safety gear such as gloves, goggles, and an N95 respirator to reduce exposure risks during cleanup.
