7 Common Home Insurance Mistakes Maryland Homeowners Make
•October 28, 2025•7 min read
Most homeowners buy a policy once, at closing, when there's a hundred other things demanding attention. Then it renews quietly for years while the house changes, the market changes, and the policy doesn't.
That's how gaps form. Not through carelessness — through time.
Here are the seven we see most often with Maryland homeowners, and what to do about each.
1. Insuring the Home for What It's Worth Instead of What It Costs to Rebuild
This is the most common and the most expensive mistake.
Your dwelling coverage should be based on replacement cost — what it would take to rebuild your home with today's labor and materials. Market value is a different number entirely. It includes your land, your location, and what a buyer would pay.
Those two figures can be far apart in either direction. In older Baltimore neighborhoods, rebuilding a home with plaster walls, original millwork, and a slate roof can cost considerably more than the house would sell for. In newer developments, the reverse is sometimes true because so much of the price is the lot.
If your dwelling limit was set years ago, construction costs have almost certainly moved since. Ask for a current replacement cost estimate and check whether your policy includes extended or guaranteed replacement cost, which provides a cushion above your stated limit.
2. Assuming Home Insurance Covers Flooding
It doesn't. Standard homeowners policies exclude damage from rising water, storm surge, and overflowing waterways.
This surprises people every year, and Maryland has more exposure than most homeowners assume — tidal flooding along the Chesapeake, rivers and creeks throughout Baltimore and Harford counties, and drainage-related flooding in neighborhoods nowhere near a designated flood zone.
Two things worth knowing:
- A lender only requires flood insurance in high-risk zones. Not being required doesn't mean not being at risk.
- Flood policies typically carry a 30-day waiting period, so buying one during hurricane season doesn't help with the storm that's already forming.
If you've never looked at flood coverage, it's worth a conversation regardless of your zone.
3. Confusing Water Damage With Water Damage
Not all water is treated the same way, and this is where claim denials most often come from.
Generally speaking:
- A burst pipe or a sudden appliance failure is usually a covered loss
- Water backing up through a drain or sewer usually needs a water backup endorsement
- Gradual seepage, long-term leaks, and damage from deferred maintenance are typically excluded
- Surface water and flooding require separate flood insurance
The water backup endorsement is one of the least expensive additions to a homeowners policy and one of the most frequently useful, particularly in older homes and finished basements. If you have a basement you'd hate to lose, ask whether you have it.
4. Never Updating the Policy After Renovations
If you finished the basement, added a bathroom, put on an addition, replaced the kitchen, or built a deck, your home costs more to rebuild than it did before — and your policy may not know.
The same applies to major systems. A new roof, updated electrical, or a replaced HVAC system can affect both your coverage need and, in some cases, your eligibility for credits.
Improvements that commonly go unreported:
- Finished basements and attics
- Additions and enclosed porches
- Kitchen and bathroom remodels
- Decks, patios, and hardscaping
- Detached garages, sheds, and fencing
- Pools, hot tubs, and outdoor kitchens
- Solar panels
A quick call after a project is finished is much easier than discovering the gap after a loss.
5. Underinsuring Personal Property — and Forgetting Special Limits
Most policies set personal property coverage as a percentage of your dwelling limit. That figure is a default, not a calculation of what you actually own.
Two things to check:
Whether you have replacement cost or actual cash value on contents. Actual cash value pays depreciated value — a ten-year-old sofa is worth very little. Replacement cost coverage pays what it costs to buy a comparable new item, and the difference at claim time is substantial.
Whether your valuables exceed the special limits. Even a well-written policy caps certain categories regardless of your overall limit. Jewelry, watches, furs, firearms, silverware, coins, and collectibles typically have their own sub-limits — often a few thousand dollars.
If you own an engagement ring, inherited jewelry, or a collection of any real value, those items likely need to be scheduled individually. Scheduling usually also removes the deductible and broadens what's covered, including mysterious disappearance.
While you're at it: photograph or video every room, keep receipts for major purchases, and store it somewhere that isn't in the house. Documenting what you own before a loss is the single most useful thing you can do for a future claim.
6. Leaving Liability Limits at the Default
Dwelling coverage protects the building. Liability coverage protects everything else you own.
If someone is seriously injured on your property — a guest on the stairs, a delivery driver on an icy walk, a neighbor's child at the pool — or if your dog bites someone, liability coverage is what stands between a judgment and your savings, your investments, and your future income.
Many policies default to $100,000 or $300,000. For a household with meaningful assets, that can be low. Higher limits are usually inexpensive relative to the exposure, and umbrella coverage extends liability protection above your home and auto limits for a modest annual cost.
Worth reviewing if you have a pool, a trampoline, a dog, teenage drivers, rental property, or you host frequently.
7. Shopping on Price Alone
It's reasonable to want a lower premium. The problem is that premium alone tells you almost nothing.
Two policies at different prices can differ on:
- Dwelling limit and whether extended replacement cost is included
- Replacement cost versus actual cash value on contents
- Roof settlement — some policies pay depreciated value on older roofs rather than replacement cost, which can mean a difference of many thousands of dollars
- Wind and hail deductibles, which are sometimes a percentage of the dwelling limit rather than a flat amount
- Water backup, service line, and equipment breakdown endorsements
- Liability limits
- Claims handling and local support
A cheaper policy that pays depreciated value on a fifteen-year-old roof isn't a savings. It's a bill you haven't received yet.
A Simple Annual Habit
Once a year, spend twenty minutes on this:
- Confirm your dwelling limit reflects current rebuild costs
- Report any renovations or improvements
- Check whether your valuables need scheduling
- Confirm you have water backup coverage
- Review your liability limits against your assets
- Ask which discounts you currently qualify for
- Update your home inventory
That's the whole list. Doing it consistently is what keeps a policy from drifting out of alignment with the home it's supposed to protect.
