Water in your Fairfield County home?
If water is coming into your Fairfield County home, shut off the main water valve, turn off power to wet areas if safe, and photograph the damage. Then call your insurer and a restoration company registered in Connecticut as a home improvement contractor. This guide covers what restoration involves and how to choose a contractor.
The first hour
- Make it safe. Do not walk into standing water near outlets or appliances. Turn off power at the panel only if you can reach it from a dry spot; if the panel is in or near water, stay out and call the electric utility or an electrician.
- Stop the water. Close the main shutoff for a pipe or fixture leak. For a sewer backup, stop using sinks, toilets and appliances.
- Photograph everything. Take photos and video of every wet room, damaged item and water line on the walls before anything is moved.
- Call your insurer. Report the loss promptly and ask how they want the claim handled.
- Start drying within 24 to 48 hours. Call a registered restoration company. Extraction and drying should start quickly, because mold can begin to grow within 24 to 48 hours.

Guides to costs, insurance and flood risk
Two kinds of risk: the coast and the river valleys
Fairfield County homes get wet in different ways depending on where they sit. The flood risk by town table compares all eight towns side by side, with a source for every figure.
Which towns flood from Long Island Sound?
Shoreline towns face storm surge and tidal flooding from Long Island Sound. During Superstorm Sandy in 2012, the National Weather Service’s flood log for its Bridgeport tide gauge, which covers the Southern Fairfield coast, recorded 2 to 5 feet of water several blocks inland along western Long Island Sound, and a few feet north of I-95 along Ash Creek and the Mill River in Fairfield. In Norwalk, 207 of the city’s 227 repetitive-loss properties are in coastal zones, according to the regional hazard mitigation plan.
Do inland towns flood too?
Inland and river towns face fast rainfall flooding instead. New Canaan has no coastline at all, yet after heavy rain on August 18, 2024, the New Canaanite reported about five feet of flooding in a Marvin Ridge Road home. That same day, Wilton received more than 8 inches of rain in about 7 hours, and the Norwalk River closed Route 7 in three places, according to Good Morning Wilton.
Many towns face both. Even near the coast, intense rain can overwhelm culverts, storm drains and rivers long before any surge arrives. Basements, finished lower levels and homes near small streams are the most common places for damage to show up.
Types of water damage
Restoration crews sort water by how contaminated it is, and that shapes how the job is done. The IICRC’s S500 standard treats sewage and rising river or sea water as Category 3, grossly contaminated water; Categories 1 and 2 are the cleaner and moderately contaminated tiers. The restorer decides the category on site.
- Cleaner water: many materials can be dried in place if work starts early.
- Moderately contaminated water: more porous materials may need removal.
- Category 3 water, such as a sewage backup or floodwater from a river or the Sound: porous materials like carpet, padding and drywall that soaked it up are usually removed, and the area is cleaned and disinfected.
Whatever the water, start drying quickly. This site has detailed pages on burst pipe cleanup, flooded basement cleanup and mold remediation.
Insurance and costs
Does homeowners insurance cover sewer backup?
Usually not, unless you added it. The Insurance Information Institute says sewer backup is not covered by a typical homeowners policy or by flood insurance, and has to be bought as an endorsement or a separate product. That matters in big storms here: when Ida hit in 2021, major sewer overflows were reported around Stamford. Sudden and accidental water, such as a burst pipe or a failed supply hose, is the kind standard policies usually cover. The Connecticut homeowners insurance guide goes through each cause of water damage and how to document a claim.
Can you pay less for flood insurance?
In some towns. The Town of Fairfield takes part in FEMA’s Community Rating System, which gives about 2,256 local policyholders a 10% discount, Patch reported. The flood risk table lists what the town sources say for the other seven towns.
Is there a Fairfield County price for restoration?
No. None of the cost guides this site uses publishes a Fairfield County or Connecticut figure, so the ranges below are national. The water damage restoration cost guide lists them by job, with the publisher and date beside each, and explains what moves the price. Your adjuster and contractor should agree on the scope in writing before rebuilding begins. Keep receipts, moisture logs and any damaged materials the adjuster may want to see. The water damage FAQ collects short answers on first steps, insurance, costs and checking a Connecticut contractor.

How to choose a restoration company in Fairfield County
- Look the contractor up on the Connecticut Department of Consumer Protection eLicense lookup. Home improvement contractors must be registered, and you can verify registration there. (CT Department of Consumer Protection)
- For mold work, since October 1, 2026 Connecticut requires a registered home improvement contractor who attests to IICRC, NORMI or DCP-approved mold certification and follows ANSI/IICRC S520. Ask to see both. (Connecticut General Assembly, Public Act 26-100, June 2026)
- For water damage, ask whether the crew follows ANSI/IICRC S500, the standard for professional water damage restoration. (IICRC)
- Ask for a written estimate that lists the scope of work and what is not included, such as rebuild and repairs, before work starts.
- Tell your insurance provider about the loss early and ask what they need from you before work begins.
Insurance in Connecticut
- Flood damage is excluded from a typical homeowners policy. Flood cover is a separate policy, usually through the National Flood Insurance Program. (CT Insurance Department, September 2024)
- A new flood policy typically takes effect 30 days after purchase. (FEMA, February 2020)
- Ask your agent whether your policy covers sewer or drain backup.
- Dry water-damaged areas within 24 to 48 hours to limit mold growth. (US EPA, February 2026)

Frequently asked questions
Which towns does this guide cover?
It covers eight Fairfield County towns: Stamford, Norwalk, Greenwich, Westport, Darien, New Canaan, Fairfield and Wilton, with a local page for each.
Should I call my insurer or a restoration company first?
Stop the water and make the home safe first, then notify your insurer promptly and ask whether they want to inspect before materials are removed. Most policies expect you to prevent further damage, so drying can usually start early as long as you photograph and document everything first.
Does homeowners insurance cover a flooded basement?
It depends on the cause. Sudden internal leaks such as a burst pipe are usually covered, while rising surface water or river flooding usually needs a separate flood policy.
How quickly can mold start after water damage?
The EPA advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth, which is why fast extraction and drying matter.
How long does water damage restoration take?
HomeAdvisor's national guide says water extraction takes at least three days, a water-damaged home can take around five days to dry, and full restoration can take weeks or even months (June 2026). It adds that replacing drywall, plumbing fixtures and electrical parts can take a few days as well. No source gives a Fairfield County timeline.
