How to handle water, fire, or mold damage
Water, fire, and mold jobs are won or lost in the first 24 hours. The right firm is on-site fast, documents everything for your carrier, and dries the structure to measurable targets — not whenever the equipment "looks dry".
That covers initial dispatch, extraction, and same-day containment for a typical residential water loss. Drying-out a single room runs $1,500–4,000 over 3–5 days; full-home losses scale to $7,500–20,000+. Mold remediation runs $10–30 per sqft of affected surface. Fire restoration ranges from $1,000 for limited smoke cleanup to $20,000+ for structural rebuild scope.
Water category (clean vs. gray vs. black), how long the water sat before extraction, square footage of saturated material, and whether HVAC ductwork or insulation was contaminated — those four variables drive 80% of the cost.

These are the factors that move a quote up or down. Knowing them helps you share the right context upfront so we can quote your specific situation accurately — and so you can compare bids on apples-to-apples scope.
IICRC S500 classifies water by contamination level. Category 1 (clean water from a supply line) can often be dried in place. Category 2 (gray water — dishwasher, washing machine, aquarium) requires antimicrobial treatment and porous-material removal. Category 3 (black water — sewage, flood water, toilet overflow past the trap) requires PPE, controlled demolition, and disposal of all porous materials it touched. Same square footage, very different jobs. The category is set by the contaminated source, not how dirty the water looks.
Drying cost climbs almost linearly with hours of saturation. At 0–24 hours you are extracting and drying. At 24–48 hours you start losing drywall bottom plates, baseboards, and engineered flooring. Past 72 hours, mold is colonizing and you have shifted from drying into remediation — typically a 2-3x cost jump. This is why every reputable firm answers the phone 24/7 and dispatches inside two hours.
Drying-out is billed by equipment-day. A typical room takes 2–4 air movers and 1 LGR dehumidifier running 3–5 days. The pro should set drying targets at the first reading (moisture content of wood at 12–15%, gypsum below 1%) and pull equipment when the structure hits target — not on a fixed schedule. Ask whether daily moisture logs will be shared with you and the carrier.
Carpet pad, MDF baseboards, particleboard cabinets, and saturated batt insulation almost always come out — they hold water and grow mold whether you dry them or not. Solid wood, plaster, and tile usually dry in place. Cat 2/3 water expands the removal list. Ask for a written scope identifying what is being removed and why, so there are no surprises when the dumpster shows up.
Mold work prices per sqft of contaminated surface, not floor area. A 4x6 ft drywall bloom is different from black mold colonizing 200 sqft of attic sheathing. Scope includes containment (poly + zipper doors), HEPA negative air, controlled removal, HEPA vacuuming, antimicrobial treatment, and post-remediation verification (PRV) testing. Skip any step and the spore counts rebound.
Three distinct fire scenarios. Light smoke (e.g. kitchen grease fire contained quickly): cleaning, deodorization, HVAC purge — $1,000–4,000. Moderate (single-room fire with smoke through the home): structural cleaning, sealing, partial drywall replacement, contents pack-out — $5,000–25,000. Major structural fire: full demo and rebuild, often $50,000+. Wet smoke from low-heat plastic fires is harder to clean than dry smoke from a wood fire.
For larger losses, contents are inventoried, packed out to a climate-controlled warehouse, cleaned (ultrasonic for hard goods, ozone or hydroxyl for soft goods), and stored until the home is ready. Priced by labor + monthly storage. Most carriers cover this under ALE/contents coverage — confirm in writing before pack-out begins.
What else might come up
Most projects touch more than one trade. Here's where this one usually overlaps with others — so you can plan ahead instead of scrambling.
The leak source must be repaired before drying begins, or the structure rewets. Most restoration firms partner with plumbers but do not employ them — confirm who is making the repair and who is paying for it (carrier usually covers the resulting damage but not the failed plumbing component).
Tarp-and-dry is the temporary fix; the roof itself needs a permanent repair before reconstruction. Coordinate timing — drying equipment can run under a tarped roof, but reconstruction waits on roof close-up.
Contaminated ducts will redistribute mold spores or soot through the home forever if not cleaned. NADCA-certified HVAC cleaning is the standard. For fires, the air handler coils and blower wheel often need replacement, not just cleaning.
Submerged Romex wiring is rated for replacement, not drying. Outlets, switches, and any fire-affected runs must be evaluated and typically replaced. Required before final inspection signs off the reconstruction.
Structural rebuild (framing, kitchen cabinetry, custom millwork) is often outside a restoration firm's core competency. A GC handles the rebuild while the restoration firm hands off documentation. Coordinate the handoff with your adjuster so the rebuild estimate ties to the mitigation scope.
- Photos of the affected area — wide shot for context, close-ups of standing water, stains, or visible mold
- When the loss started (date and approximate time) and when you discovered it
- What kind of water — clean supply line, dishwasher/washer discharge, toilet/sewer, storm/flood
- Whether the source has been stopped (water shut off, fire out) or is still active
- Insurance carrier name and whether you have already filed a claim
- Age and construction type of the home (slab vs. crawlspace vs. full basement)
- Flooring types in affected areas (hardwood, LVP, carpet, tile)
- HVAC type and whether the air handler is in the affected area
- Any prior water or mold history at the property
- Whether the home is currently occupied and if anyone has health sensitivities (asthma, immunocompromised)
- Sewage smell or visible black water — Cat 3 protocol applies
- Visible mold growth on walls, ceilings, or behind baseboards — separate remediation scope
- Soot or smoke odor in unaffected rooms — indicates HVAC contamination
- Drywall that is bulging, sagging, or stained more than 24 hours after the leak — saturated and likely needs removal
- Pets or family members coughing, headaches, or eye irritation after the loss — IAQ concern, may need testing
