The honest answer to this question is that it depends on what the water did and where it came from. A homeowners policy is a contract, and the wording on your own policy has the last word. What follows is how the Maryland Insurance Administration, the state regulator, describes the common patterns. It is general information, not a coverage opinion, and your insurer is the one to ask.
Sudden and accidental versus gradual
The Maryland Insurance Administration says a suddenly burst pipe that floods floors is generally covered for the resulting water damage. The pipe itself, meaning the cost of repairing or replacing it, is generally not. That split between the damage and the failed part comes up again and again, in pipes, water heaters and appliances.
A slow leak that runs for months is usually treated differently. Insurers often exclude damage that happens gradually or that could have been prevented by maintenance. If a stain has been growing for a long time, expect more questions about when it started.
Flood is a separate policy
The Maryland Insurance Administration says homeowners policies generally do not cover flooding. Flood needs its own policy, often through the National Flood Insurance Program or a private insurer. The program's definition covers temporary inundation of normally dry land from sources such as overflowing waters or rapid surface runoff.
That is why the source matters when you describe your loss. Rain that came through a damaged roof is a different event from surface water that entered through a basement door. If you are unsure which one applies, say what you saw and let the insurer classify it.
| What happened. | Usually covered under a homeowners policy?. | What to check. |
|---|---|---|
| Pipe bursts and floods the floor. | Generally yes, for the water damage but not the pipe. | Deductible and any exclusions for freezing or neglect. |
| Appliance hose splits suddenly. | Generally yes for resulting damage. | Whether the loss was sudden and not long-term. |
| Slow leak over months. | Often excluded. | Exclusions for gradual or repeated seepage. |
| River overflow or surface runoff. | Generally no, flood needs its own policy. | Whether you carry flood insurance. |
| Foundation seepage. | Treated as a maintenance issue and generally not covered. | Policy language on groundwater. |
| Sewer or drain backup. | Only with an endorsement. | Whether you added the endorsement. |
Sewer and water backup is an add-on
The Maryland Insurance Administration says coverage for sewer or water backup is typically added by endorsement, and that Maryland law requires insurers to offer it. Many homeowners learn they lack it only after a backup. Check your declarations page today, because the endorsement is cheaper before a loss than useless after one.
If you already have a backup, our page on sewage backup cleanup explains what the cleanup involves, and the flood damage page explains how outside water is handled.
What this means in Catonsville
Catonsville is an unincorporated community in Baltimore County, and its western and southern edge follows the Patapsco River. The National Weather Service reported that on May 27, 2018 radar estimated 6 to 12 inches of rain, with 9 inches or more near and southwest of Old Town Ellicott City and toward Catonsville. Storms like that are exactly the events where the flood versus water damage line becomes a real question.
Check whether your parcel appears on the FEMA Flood Map Service Center and ask Baltimore County about your address. Baltimore County requires building permits for work in a 100-year floodplain, which can affect how a flood repair is done even when insurance helps pay for it.

What to do right after water damage
- Stop the water and make the area safe.
- Photograph and video everything before moving it.
- Prevent further damage, since policies expect you to protect the property.
- Keep receipts for emergency repairs and equipment.
- Call your insurer to report the loss and ask what documents it needs.
The Maryland Insurance Administration also advises reporting claims promptly. It does not state a single claim deadline, so check the filing window in your own policy.
How a restoration company fits in
A restoration company does not decide coverage. It dries your house, records what it finds and gives you documents your insurer can review. Moisture readings, photographs and equipment logs show what was wet and for how long. Those records are often the difference between a smooth claim and a dispute. Ask for them even if you are not sure you will file.
If your house was affected in Howard County, rules for permits and utilities differ. Our Ellicott City page covers that side, and the Baltimore page explains the city programs.
When a restoration company says it follows the ANSI/IICRC S500 standard, it means its categories and records follow a published method. Your insurer can then compare them with its own questions about the loss.

Catonsville insurance questions
Usually not. The Maryland Insurance Administration says homeowners policies generally do not cover flooding and that flood needs a separate policy. Sewer or drain backup needs an endorsement. Read your declarations page and ask your insurer which applies to your loss.
Generally the pipe repair is not covered, though the resulting water damage often is. The Maryland Insurance Administration describes this split for suddenly burst pipes.
The state guidance advises reporting promptly but does not give one deadline. The filing window is in your policy, so read it and ask your insurer.
No. Only your insurer decides coverage. A restoration company can document the loss with photos and moisture logs.
