1. Stop the water at the source
Before you fix anything, stop more water from coming in. For a burst or leaking pipe, shut off your home's main water valve (usually near the street, garage, or where the water line enters the house). For a roof leak, place buckets and tarps until it can be patched. For an appliance leak, unplug it and turn off its supply line.
If the water is coming from outside flooding rather than a plumbing failure, the approach is different — see our guide on flood cleanup for storm and flood situations.
2. Make the area safe
Water and electricity are a dangerous mix. If water is near outlets, appliances, or your electrical panel, switch off the power to that area at the breaker before stepping in. Wear rubber boots and gloves. If the water came from a sewage line or toilet overflow, treat it as contaminated (Category 3) — it needs sewage backup cleanup, not a mop and bucket.
3. Remove standing water quickly
The first 24–48 hours matter most. Remove standing water fast using a wet/dry vacuum, mop, and towels for small amounts. For anything more than a few gallons or water that has soaked into flooring, a submersible pump or professional water extraction equipment moves far more water than household tools and gets under the surface where damage hides.
- Lift furniture off wet carpet and place foil or wood blocks under legs to stop staining.
- Remove soaked rugs, cushions, and small items to dry separately.
- Pull up sopping carpet and padding if water sat for more than a day — padding rarely survives.

Call (833) 844-07494. Dry the structure completely
This is the step most people rush — and it's why mold shows up weeks later. Walls, subfloors, and framing hold moisture you can't see. Open windows, run fans and dehumidifiers around the clock, and keep drying for several days, not hours. Professionals use air movers and moisture meters during structural drying to confirm materials are actually dry, not just dry to the touch.
Check hidden spots: behind baseboards, inside wall cavities, under cabinets, and beneath flooring. If drywall feels soft or a moisture meter reads high after 2–3 days, that section usually needs to come out.
5. Repair the damaged materials
Once everything reads dry, you can rebuild. Common repairs include:
- Drywall: cut out swollen or stained sections, replace, tape, mud, and repaint.
- Flooring: warped laminate and buckled hardwood usually need replacing; tile may only need regrouting if the subfloor stayed dry.
- Paint & trim: prime water stains with a stain-blocking primer before repainting or they bleed through.
For extensive damage across multiple rooms, full water damage restoration restores structure and finishes together so nothing gets missed.
6. Prevent mold from returning
Mold can start growing in 24–48 hours on damp material. After drying, clean hard surfaces with a detergent solution, keep humidity below 50%, and watch for musty smells or dark spots over the following weeks. If mold covers more than about 10 square feet, bring in a professional rather than disturbing it yourself.
When to call a professional
Handle it yourself if it's a small, clean-water spill you caught within hours. Call a pro when: water sat overnight, it spread across rooms or into walls, it involves sewage or storm water, or you see any sign of mold. We serve homeowners across Thousand Oaks, Simi Valley, Camarillo, and Moorpark with 24/7 emergency water damage restoration — the sooner drying starts, the less you replace.
Frequently Asked Questions
How long does it take to fix water damage?
Minor water damage can be dried in 3–5 days, but full repairs (drywall, flooring, painting) often take one to two weeks depending on how far the water spread and how quickly drying started.
Can I fix water damage myself?
Small, clean-water spills caught within a few hours are often DIY-friendly. Water that sat overnight, spread into walls or flooring, or involved sewage should be handled by professionals to prevent mold and structural problems.
Does water damage always cause mold?
Not always — but mold can begin growing within 24–48 hours on damp materials. Thorough, fast drying is the single best way to prevent it.
What should I do first when I find water damage?
Stop the water source, turn off power to the affected area for safety, then remove standing water as quickly as possible. Speed in the first 24–48 hours limits the damage the most.
