Is it urgent?

Fire, gas, a CO alarm or water at outlets? Get out and call 911. Don't wade where power may be live.

Emergency: call now

  • Active flooding or leak
  • Overflowing appliance
  • Sewage backup
  • Storm water coming in
  • Fire or smoke damage

Within a day or two

  • Still wet: mold clock on
  • Breach needs a tarp
  • Mold, someone vulnerable
  • Hidden wet walls

Can wait: schedule it

  • Past event, already dry
  • Old mold to test
  • Old smoke odor
  • Rebuild after drying
Rule of thumb: If water or damage is actively spreading, it is an emergency. A dried-out or cosmetic situation is an assessment.Good to know: While you wait: shut off the water at the main, move valuables up, lift rugs, do not vacuum standing water, and stay out of sewage.
The full list, in the guide's words

Safety first: Fire, smoke filling the home, a gas smell, a carbon monoxide alarm, a downed power line, or floodwater touching outlets or the panel: get everyone out and call 911 (or your gas utility for gas). Shut off power at the breaker only if you can reach it without standing in water, and do not wade into water where electricity may be live.

Emergency: call now

  • Active flooding or a burst or leaking pipe that is still releasing water
  • An overflowing appliance, a sewage backup, or storm water coming in through a breach
  • Fire or smoke damage right after the scene has been cleared

Within a day or two

  • Water already removed but materials still saturated, so the 24-48 hour mold window is running
  • A roof or window breach that needs a tarp before the next rain
  • Mold in a household with someone vulnerable or symptomatic, or hidden saturation behind walls

Can wait: schedule it

  • A past water event that has already dried
  • Old or cosmetic mold you want tested, a smoke-odor quote about an old event, or a rebuild estimate after drying is done

This is general guidance, not a diagnosis. If anyone is in danger, call 911 first.

What's on the quote

  • Emergency servicesAsk: extraction, board-up, tarp?

    Water extraction, board-up or tarping, and stabilizing the property.

  • Drying & monitoringAsk: how many days, how logged?

    Fans (air movers), dehumidifiers and daily moisture readings. Often billed per piece of equipment per day of use, so ask for the expected number of days and how drying is documented.

  • Demolition & disposalAsk: what can't be saved?

    Removing wet drywall, flooring and insulation that cannot be saved.

  • Cleaning & treatmentAsk: odor control, belongings?

    Antimicrobial treatment, odor control and cleaning of belongings.

  • DocumentationAsk: moisture logs and photos?

    Moisture logs and photos that your insurer may ask for.

  • ReconstructionAsk: a separate scope for rebuilding?

    A separate scope for rebuilding. Ask whether the company does both and how the estimate separates them.

  • What a good estimate spells out9 things to look for
    • The contractor's legal name, license number if one applies, and contact details, plus your name and address.
    • What work is included, and what is not.
    • The brand, model and size of major equipment and materials, not just standard or builder grade.
    • Who pulls the permit and who pays for it and for inspections.
    • Cleanup, and what happens to the old materials.
    • A start date and a realistic finish date, and what happens if the schedule slips.
    • Warranty terms: what is covered, for how long and who honors it.
    • When and how you pay, tied to finished stages of work rather than just dates.
    • How changes are handled: a written price for any change before the work happens.

Red flags

4 of 12

  • Signing over your claim

    Understand any form before you sign it.

  • "Insurance pays for everything"

    Your insurer decides coverage.

  • Tear-out with no moisture readings

    Ask what is actually wet.

  • Drying days don't match the log

    Equipment billed should match readings.

8 more red flags

  • A company that arrives unprompted after a disaster.

  • Pressure to sign today, or a price that is only good right now.

    A fair quote is still fair tomorrow.

  • No written quote, or a quote that is a single total with no detail about what is included.

  • A large payment up front, or a request for cash only.

    Some states limit how much a contractor can ask for before work starts.

  • A license number that does not check out.

    Where your state licenses this trade, look the number up yourself on the state licensing board's site.

  • No proof of insurance.

    Ask for a certificate sent to you directly by the insurer or the agent.

  • A price far below every other quote, followed by extras once the work has started.

  • Someone who knocks on your door uninvited, or who will not give recent local references.

Where homeowners say it goes wrong

  • They're overwhelmed and don't know who to call, what to do first, or whether it's even safe to stay in the house
  • They're terrified of the cost and confused about whether and how their insurance covers it
  • They don't know the difference between mitigation and the rebuild, or how long drying takes, or what's salvageable
  • They worry about hidden mold and long-term damage they can't see behind walls or under floors
  • They've been told to act within 24-48 hours before mold sets in and they feel the clock running
  • They fear a contractor will overcharge or pad the insurance claim, or that the carrier will fight them on coverage

Ask every restoration company

  1. What will you do on the first day, and what will you document (moisture readings, photos) so my insurer can see it?

  2. How many fans and dehumidifiers do you expect to use and for how many days, and how will you know the structure is dry?

  3. What is mitigation and what is rebuilding in your estimate, and do you do both or hand off?

2 more questions

  1. Are you licensed where this work requires it, and insured? Can I see the license number and a certificate of insurance sent to me by your insurer?

  2. What exactly does the warranty cover, for how long, and who honors it (you, the manufacturer, or both)? Will you put it in writing?

Permits

Some of this work needs a permit and some does not. It depends on the scope of the job and where you live.

Emergency drying and tarping usually do not need a permit. Rebuilding after damage often does, and fire or mold remediation can have its own local rules.

  • Your building department decides what applies at your address. Rules differ by city and county, and HOA, condo or historic-district rules can add more.
  • Ask who pulls the permit. Normally the licensed contractor does and the price includes it. If a contractor asks you to pull it in your own name, ask why: it can shift responsibility for the work to you.
  • If you are unsure, call your local building department before you sign. Unpermitted work can cause problems with insurance and when you sell.

Paying for it

Before you finance anything6 basics, then the financing guide

Most home projects can be paid in cash or financed. A few basics before you sign anything:

  • Ask for the cash price and the financed price in writing, for the same scope of work. They can differ, because a financing fee (sometimes called a dealer fee) may be built into the financed price.
  • Compare the total you will pay over the whole loan, not just the monthly payment.
  • Read the fine print on same-as-cash and zero-interest offers, especially what happens if the balance is not paid in full by the end of the promotional period.
  • PACE financing is repaid through your property tax bill and can place a lien on your home. Read the terms closely, and consider asking your mortgage servicer how it is treated, before you agree.
  • Utility and state programs sometimes offer low-rate loans for efficiency work. Check yours before accepting the contractor's offer.
  • Take loan paperwork home and read it. A sign-it-today loan is a reason to slow down.
