Frequently asked questions
Most water damage questions come down to three things: what to do first, what insurance covers and what the work costs. In short, stop the water, document the damage, call your insurer and a registered restoration company, and start drying within a day or two. The answers below cover Fairfield County homes.
Answers for your kind of water damage
A burst pipe is usually the clearest insurance case, because a standard policy covers a sudden discharge from plumbing. The burst pipe cleanup guide covers the first hour after a break, how drying is measured and when the repair needs a town permit.
Water that rose into a basement from a river, the Sound or a flooded street is a different case. The IICRC counts rising river and sea water as Category 3, and a typical homeowners policy does not cover flood. The flooded basement cleanup guide explains pumping, drying and what has to be removed, and the homeowners insurance guide sets out which policy pays for which water.
If mold is already growing, the 24 to 48 hour drying window has passed. The mold remediation guide covers the size of patch a homeowner can clean and what Public Act 26-100 has required of Connecticut contractors since October 1, 2026.
Each town guide covers its own flood record, offices and rebuild rules. Along the Sound, they cover Pemberwick and the Byram River in Greenwich, the hurricane barrier in Stamford, the Noroton River and culverts in Darien, tidal flooding in South Norwalk, the Saugatuck River and flash floods in Westport and Fairfield Beach and the Rooster River. Inland, cloudburst flooding in New Canaan and the Norwalk River, wells and septic in Wilton have guides of their own.

All questions
What should I do first after water damage?
Stop the source by closing the main water shutoff, turn off power to wet areas if you can do it safely, and photograph everything. Then call your insurer and a registered restoration company.
Does homeowners insurance cover water damage?
Usually, if the damage is sudden and accidental. The Insurance Information Institute says a standard HO-3 policy covers accidental discharge of water from a plumbing system, such as a burst pipe, but excludes seepage, which it treats as a maintenance issue. The Connecticut Insurance Department says flood is not covered by a typical homeowners policy.
Does homeowners insurance cover sewer backup?
Not a typical policy. The Insurance Information Institute says sewer backups are not covered by a standard homeowners policy or by flood insurance, and that the coverage must be bought as a separate product or as an endorsement, usually at a nominal cost. Check your declarations page or ask your agent.
How do I file a water damage insurance claim?
Report the loss promptly, document the damage with photos and video before cleanup, and keep moisture logs, invoices and receipts. The Connecticut Insurance Department also says not to throw out damaged property until an insurance adjuster has reviewed it for your claim.
Is a burst pipe covered differently from a flood?
Yes. A sudden burst pipe is usually covered by homeowners insurance, while flooding from rising surface water, rivers or storm surge needs a separate flood policy. FEMA says a new National Flood Insurance Program policy usually has a 30-day waiting period, so buying one when a storm is forecast is usually too late.
Can you live in a house with water damage?
It depends on the damage. EPA says to assume a home is unsafe if walls lean, a roof sags or new cracks appear, and not to enter until the electricity is off. People with asthma or weakened immune systems should stay away from moldy areas, and children and pregnant people should not do cleanup. A pipe leak typically presents fewer hazards than a flood, EPA says.
How soon can mold grow after water damage?
Quickly. The EPA advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth, so extraction and drying should start as soon as the water is stopped and the damage is photographed.
What are the categories of water damage?
The IICRC's S500 standard sorts water into three categories by contamination. Category 3 is grossly contaminated water, which includes sewage and rising river or sea water; Categories 1 and 2 are the cleaner and moderately contaminated tiers. The restoration company decides the category on site, and it shapes what has to be removed.
How long does water damage restoration take?
HomeAdvisor says a water-damaged home can take around five days to dry, though this depends on the damage. Repairs and rebuilding come after drying. Ask the restoration company for its daily moisture readings, so you can see when the materials are dry enough to close up.
How much does water damage restoration cost in Connecticut?
No publisher gives a Connecticut figure. HomeAdvisor's national data puts a typical job at $1,383 to $6,369 (June 2026), and Fixr's at $1,200 to $5,000 (January 2025). Rebuilding drywall, flooring and finishes is usually billed on top of drying, so compare written estimates from registered Connecticut contractors.
How much does it cost to clean up a flooded basement?
HomeAdvisor (June 2026) and Fixr (January 2025) both put typical flooded basement cleanup at $2,000 to $7,000 nationally. That covers cleanup only. Sewage in a basement costs far more: HomeAdvisor gives $7,000 to $15,000 for black water cleanup, national data as of June 2026.
How much does mold remediation cost?
This Old House puts mold remediation at $10 to $25 per square foot, or $1,200 to $3,750 for a typical job (March 2026). Fixr gives $10 to $30 per square foot and $1,500 to $9,000 (August 2025). Both are national figures; no publisher gives a Fairfield County price.
How do I choose a water damage restoration company?
Confirm liability insurance and Connecticut home improvement registration, ask for daily moisture readings and a written scope, and ask how the company works with insurance adjusters. Read any work authorization before you sign it, and be cautious of anyone who pressures you to sign over insurance benefits.
Does a water damage restoration company need to be registered in Connecticut?
Yes, for residential work over $200. Public Act 26-100 defines home improvement to include water, fire or storm restoration and mold remediation on a private residence when the total price is over $200, and the Department of Consumer Protection says home improvement contractors must be registered.
How can I check a Connecticut contractor's registration?
Use the Department of Consumer Protection's eLicense lookup. Choose Online Services, then Lookup a License, search for the contractor and check that the Credential Status is active. Do this before signing a contract or a work authorization, and keep a note of the registration number.
Does a mold remediation contractor need a license in Connecticut?
Not a stand-alone mold license, but Connecticut does regulate the work. Since October 1, 2026, Public Act 26-100 requires residential mold remediation contractors to be registered home improvement contractors, to attest to IICRC, NORMI or state-approved certification, and to follow the ANSI/IICRC S520 standard.
