Does Homeowners Insurance Cover Water Damage? A Berks Answer

Homeowners insurance covers water damage when the water came suddenly from inside the house: a burst pipe, a water heater that rusted through, a washer hose that split. The standard policy pays for what the water ruined and for opening the wall to reach the pipe. It doesn't pay for the worn-out pipe, heater or hose that let go, and it never pays for flood, sewer or drain backup, sump overflow or groundwater; a leak you knew about and let run is likely to be turned down too. Company forms differ, and an insurance agent in Berks County can read yours with you.

Sudden water from inside the house is covered, but the pipe that let go isn't.

For water, the standard policy names the covered case: accidental discharge or overflow of water or steam from a plumbing, heating, air conditioning or sprinkler system or a household appliance. Look for that phrase on your policy.

The wet floor, the soaked drywall and the belongings the water ruined are the claim. The hose, the heater or the pipe that wore out and let go is your bill. If the furnace or air conditioner leaked, the post on whether homeowners insurance covers HVAC replacement applies the rule to it.

Two things work against that coverage. Known leaks: a drip under the sink or behind the toilet you watched for months is a maintenance problem, and companies say the damage it caused is likely to be denied. A leak inside a wall or ceiling that you couldn't have seen is judged on the same accidental-discharge case, and the form sets no time limit on it. Cold: a frozen pipe is covered only if you kept reasonable heat on or drained the water; turn the heat off for a winter trip and the burst pipe may be yours.

A storm that opens the roof is covered; a roof that leaks from age isn't.

When a storm tears shingles off and rain follows, the water damage inside is part of the covered storm loss. A roof that leaks because it's old and worn is wear and tear, and the roof itself is your bill; the wet ceiling under it is a claim to make, because the standard form's wear-and-tear exclusion says damage that follows and isn't excluded elsewhere is covered.

Belongings follow a stricter rule: rain, snow or sleet damage to what's inside is covered only if wind or hail first made the opening.

Mold is covered only when a covered leak grew it inside a wall.

Mold, fungus and wet rot are excluded on the standard policy, with one exception: mold hidden inside walls, ceilings or under floors that grew out of a covered leak is covered as part of that loss.

Pennsylvania's Insurance Department says to ask your agent two questions: what types of water damage does my policy cover, and does it cover mold?

Flood, sewer backup and groundwater are never on the standard policy.

Three kinds of water are excluded outright: flood, surface water and the overflow of any body of water; water that backs up through sewers or drains or overflows from a sump or sump pump; and groundwater that seeps or flows through a foundation, floor, patio or wall. A sump pump, a roof drain, a gutter and a downspout aren't a "plumbing system" on the form, so their water isn't covered. A drain pipe that leaks inside the house is plumbing, and the leak is the covered case; what the policy excludes is water that backs up through a sewer or drain, whatever pushed it back.

More than a quarter of Berks County's homes were built before 1940, and more than half of Reading's. Those are the houses with the oldest pipes, drains and laterals (the lateral is the pipe from the house to the sewer main). The pipe or heater that failed from age isn't paid for; the water it let loose inside is, unless it was sewage backing up a drain or groundwater through the wall.

Two add-ons cover the drain, the sump and the buried pipe.

The water backup add-on (an endorsement, usually a small extra cost) puts the drain and the sump back on the policy. It pays, up to the limit on your declarations page (the policy's front page), for water that backs up through sewers or drains or overflows from a sump or sump pump. It doesn't pay for the pump itself.

Water that rose out of the sump pit after the pump quit or the power went out is sump overflow, and the add-on pays. Water that came in through the foundation walls or the floor is groundwater, and neither the standard policy nor the add-on pays for it. If you can't tell which, photograph where the water came in before you clean up.

A Wyomissing agency, Spotts Insurance Group, says the same on its site: the endorsement covers sump overflow "even if the backup of water is due to the mechanical breakdown of the sump pump."

The service line add-on pays for the buried lines between the house and the street when they fail from wear and tear, rust, freezing, tree roots or animal damage, the kinds of failure the standard policy treats as wear. One regional carrier sells it inside its home policy bundles, up to $10,000 with one and up to $25,000 with the other. Without it a collapsed lateral is your bill; the post on what a sewer line replacement costs in Berks County shows what that runs.

If you're a Muhlenberg Township Authority sewer customer and sewage came up the drain, the authority reimburses up to $2,500 for an interior backflow valve (a valve that lets sewage out but not back in) or $5,000 for an exterior one. The program is for backups from the authority's own sewer system: the valve work must come within 120 days of such a backup, or the home must be in an area the authority designates flood-prone. It pays for the valve only; ask the authority about it.

Here's how the standard form sorts the water you're looking at.

The water you're looking at	The standard policy	What covers it instead
A pipe burst inside the house, or a supply hose let go	Pays for the wet floor, walls and belongings and the tear-out to reach the pipe; not a pipe or hose that failed from wear	Nothing else
A water heater or appliance rusted through and flooded the floor	Pays for the water damage and the tear-out; not the heater or appliance	Nothing else
A storm tore the roof open and rain came in	Pays for the house; belongings only if wind or hail made the opening	Nothing else
The roof leaked because it's old	The roof itself is wear and tear, not covered; the ceiling under it is a claim to make	Nothing on the policy for the roof
A leak you knew about ran for months	Likely denied: companies treat it as maintenance	Nothing on the policy
Sewage or drain water backed up into the basement	Excluded	The water backup add-on, for the damage inside
Water rose out of the sump pit after the pump quit or the power went out	Excluded	The water backup add-on, for the damage; not the pump
Water came in through the foundation walls or the floor after rain	Excluded, and the backup add-on excludes it too	Nothing on the policy
The creek came up and the water came in	Excluded	A flood policy, bought separately

Where each kind of water lands on the industry's standard form; your company's form can read differently.

If your water came up a drain or out of the sump pit, find your declarations page tonight and look for the words "water backup"; the paperwork may say sewer or drain backup, or sump discharge or overflow. If it's there, that water is a claim on the add-on: call the company tonight. If it isn't, the damage is yours for that kind of water, and adding it is a conversation with an insurance agent in Berks County before the next storm.

What to do tonight, and how the claim runs from there.

First stop the water, because the standard policy can refuse a claim for neglect if you didn't use reasonable means to save the property. Then:

1. Stop the water where you can. For a pipe, shut the main valve; for a basement, pump out the water and move what's on the floor.
2. Photograph everything before you clean up, the room and where the water came in.
3. Call the company or your agent as soon as possible, and write down who you spoke to and when.
4. Call a Berks County plumber for the pipe, the drain or the pump; the plumber's note on what failed is evidence.
5. Make only the repairs that stop more damage; no permanent repairs until the company has inspected and approved them.
6. Save every receipt.

A denial has to be in writing and name the policy provision it rests on. Don't rush the settlement; if the claim is denied, appeal to the company's claim manager and call the Insurance Department's consumer line at 1-877-881-6388. The claim steps are the same for every kind of damage, and the post on whether homeowners insurance covers electrical work walks them in more detail, along with whether a home warranty, which isn't insurance, pays for a worn-out heater or pipe.

Questions people ask.

Does homeowners insurance cover plumbing?

It covers what the plumbing did, not the plumbing: a burst pipe is a claim for the floor and the wall the plumber opens, and a pipe that failed from age is your bill.

Does flood insurance cover sewer backup?

No. It isn't on a flood policy or the standard policy; the water backup add-on covers it, and excludes a backup a flood caused.

How long does the company have to answer my claim?

Pennsylvania's rules give it 10 working days to acknowledge the claim, 30 days to finish investigating or explain the delay in writing, and 15 working days after your signed, sworn proof of loss to accept or deny it, or to tell you it needs more time and why.

So tonight: stop the water, photos, the company, the plumber. If it came up the drain and water backup isn't on your declarations page, buy the add-on before the next storm.
