Water Damage Insurance Claims in MA

What does a homeowners policy generally cover when water gets in?

Sudden, accidental water that escapes from the things in your house — supply lines, water heaters, washing machines, dishwashers and drainage pipes — are usually covered. Water damage from failure of those systems is usually a covered loss if the failure itself was sudden and not from neglect.

A pinhole in a supply line, a burst in a hose, a water heater that fails without warning, and a dishwasher that overflows in a cycle are the straightforward cases. They fit the pattern of sudden and accidental, and the damage follows from something inside the building.

The word sudden is the key. A small, chronic leak that went unnoticed for weeks or months has a different set of arguments, and a policy may not cover the damage that built up over time, even if the leak itself was accidental. An honest adjuster will look at what the property owner saw or could have seen, when it could have been noticed, and what steps were taken in between.

Which water losses usually sit outside a standard policy?

Flood, mudflow and landslide are generally handled outside a standard homeowners policy, usually through the National Flood Insurance Program or a separate endorsement. Sump pump failure, sewer backup and groundwater seepage are typically excluded unless endorsed. Water that seeped for a long time is often excluded whether or not the opening was gradual.

Flood is the named exclusion. A cellar that fills from groundwater in a saturated spring, water that comes off the ground from heavy rain or thaw, and overflow from a nearby stream or river are all handled differently from internal water losses. The National Flood Insurance Program is the route most homeowners take, and it sits outside standard homeowners coverage.

Sump pump failure is the next line. A pump that lost power, a pump that failed mechanically, or a pit that overflowed during a heavy rain — all of those leave water on your cellar floor. A standard policy generally excludes that loss unless a specific endorsement was added to the policy.

Sewer backup is another separate case. Water that came back up the house drain from a town line, or a septic system that failed or flooded, is typically excluded from the standard policy. Again, an endorsement handles it if the owner paid for it in advance.

The Division of Insurance guide to residential claims lists these as the general pattern. Your own policy will have specific language, and your insurer has the final word on whether your loss fits it. Ask, and read the answer in the policy itself rather than taking somebody's summary.

Why does mitigation affect whether a claim is paid?

Because mitigation is expected of you, and the policy language often ties coverage to the steps you took. The California Department of Insurance guide for residential claims says a policy may not cover ensuing damage if you did not take reasonable steps to secure the property, so mitigation is part of the claim and not separate from it.

As soon as you know there is water, stopping it and limiting the damage is what any property owner would do. That is mitigation. Turning off the main water, pumping the cellar, running fans and dehumidifiers, removing wet cardboard and textiles, opening the house for air — these are the obvious things and they are genuinely expected. Delaying because you are waiting for approval or an adjuster is not a strategy that works.

That means calling a restoration crew and telling them to start work does not have to wait on the insurer. In fact, waiting has the opposite effect: every day lost to delay widens the scope and shrinks the argument for full coverage. The call here is answered 24/7, a crew is sent as soon as one is free, and the scope is explained and approved on site before work starts. The claim is a separate thing you handle with your own insurer.

What should you photograph and keep?

The water at its height, the waterline on the wall or floor, the source if visible, each damaged item, and anything removed before it is thrown out. Take the pictures in their original location rather than posed, and date the file or note the time so the sequence is clear.

Once water is pumped and things are dried, the evidence of how deep the water ran and what it touched directly is gone. A photograph of water against the boiler tells a story a dried stain cannot. Keep the pictures in a folder with a label and date, and back them up rather than relying on a phone that gets replaced.

Contents matter as much as structure. A couch, a box of tools, a filing cabinet of documents, photo albums — all of these are line items on the claim eventually, and a photograph showing what the water reached and how deep it was becomes the evidence. Keep the ruined things on one side of the cellar if you can, or photograph them before they leave. An adjuster will want to see them if the claim becomes a question.

Write down what was there before. If you have a floor plan, inventory, or a video tour of the cellar from before the loss, that becomes useful evidence too. What is not documented becomes arguable later.

• Water at its highest point and the line it left on the wall
• The source of the water if you could identify it
• Each item damaged, in place if possible before it is moved
• The boiler, water heater, furnace, panel or other equipment that went under
• Removed items with enough context to show what they are
• Dates and times on each image or in a log beside them

What does the adjuster look at during the visit?

The adjuster reads the moisture in the materials, checks the source of the water, photographs the damage, measures the affected area, asks whether you took steps to stop the loss, and reads what the policy covers. They will look at contents and structure separately, take notes and pictures, and usually leave with a preliminary range for the claim.

Bring your own photographs and notes to the adjuster visit. If the source was a supply line, show the shut-off valve and the failed connection. If water spread upstairs to a ceiling, show where it came from and what is still wet. Have the photograph log ready so the adjuster can see what things looked like at the start.

The timing of the adjuster visit matters. It comes after your crew has extracted the water and started drying, because the adjuster needs to see the materials before they are torn out but after the standing water is gone. A basement that is still flooded tells the story differently from one that is being dried, so getting that first 24 hours of work done is part of showing your claim in the right light.

Be ready to talk about what you did the moment you found it: what you shut off, what you pumped out, who you called, when. The adjuster is checking that you did what any reasonable property owner would do, not that you did everything perfectly. If you pumped out the basement yourself instead of calling immediately, say so. If you waited because it was 2 a.m. and you did not know what to do, that is honest too.

How are contents and structure handled separately?

The claim usually has two parts: the building damage (drywall, flooring, insulation, plaster, mechanical equipment) and the contents damage (furniture, textiles, documents, stored items). They are on separate schedules, have separate depreciation rules, and require separate lists and photographs.

Building damage is what remains in place and is part of the property. A water-damaged boiler, wet insulation, ruined flooring and plaster — these are all structural and they drive the scope of drying and reconstruction. They are measured in square footage and in the cost to replace them.

Contents are the moveable things: the couch, the boxes of storage, the tools, the appliances brought from another room. They depreciate faster than structure, they require a separate list (make a spreadsheet if the loss is big), and they require photographs and proof of ownership or purchase price if the insurer questions them. Keep the receipts from before the loss if you have them. If not, simply describe the item, note its age and condition before the water, and ask for a depreciated value rather than a replacement cost.

What happens if the claim is denied or stalls?

The insurer must explain a denial with the specific policy language, and the Division of Insurance takes consumer complaints through its Request for Assistance form and its consumer hotline. The division cannot decide the cause of loss, but it can check the insurer's reasoning against the policy and the Massachusetts insurance code.

A denial will arrive in writing with a reason: the loss is not covered under your policy, or the policy language excludes it, or the insurer has decided it was not sudden or accidental. Read the letter line by line and find the specific policy section it cites. Then read that section in your own policy to see whether the insurer's reading matches the words.

If the reading seems wrong, or if the claim has simply stalled and nobody is answering, the Massachusetts Division of Insurance, Consumer Service Unit is the place to file a complaint. It is not a legal advocate for you and it cannot order the insurer to pay, but it forwards complaints to the company, checks their response against the policy and the insurance code, and can explain what coverage rules mean. The division takes complaints through a Request for Assistance form at its website.

Appeal is another route. Some policies allow a formal appeal of a denial, usually within a certain time. The notice of denial should say what that process is. It is usually faster than going to the Division of Insurance, and it keeps everything within the company.

How does a sump pump or sewage backup claim differ?

Both are typically excluded from standard coverage unless the policy was specifically endorsed for them. Sump pump failure and sewage backup have different damage patterns, happen regularly in some houses, and standard policies treat them as separate risks that need separate endorsements.

A pump that stops because the power went out or because it failed mechanically leaves standing water until the pit overflows and the cellar floods. A sewage backup pushes contaminated water up a drain and creates a disposal and health problem as well as a water damage problem. Both are real, and both are expensive, but they are not the same loss.

The endorsements for these are usually called a water backup and sump pump exclusion waiver or something similar. If you do not have one and the claim is denied as an excluded loss, the question is whether it was worth the premium in advance. For properties with a history of flooding or with a sump pump in an old house — which is most of the houses here — the answer is usually yes.

Sump pump failure water damage and sewer and septic backup cleanup cover the cleanup side of each.

For New Hampshire readers: where do I complain about my insurer?

The New Hampshire Insurance Department, Consumer Services Unit handles complaints. It forwards a complaint to the insurer, checks the response against the statutes, rules and the policy, and can explain policy terms. The department handled 2,081 property-and-casualty cases in 2023.

The process and timelines are similar to Massachusetts: the insurer must answer, and the department checks the answer against your policy and state law. It cannot order the company to pay, but it can ask questions about the denial and require the insurer to explain the reasoning.

For coverage questions and general information you can phone or visit the department's website. The consumer hotline is listed there.
