Is Your High-Value Home Properly Insured? 7 Coverage Gaps NJ Homeowners Should Review
If you own a home worth $1 million, $2 million, or more in New Jersey, you've probably invested a significant amount of time and money into your property.
Maybe you've renovated the kitchen, finished the basement, added custom features, or simply watched your home's value increase over the years.
But here's a question worth asking:
If something happened to your home tomorrow, would your homeowners insurance provide the coverage you expect?
At The Overmyer Insurance Agency (OIA), we review homeowners policies to help identify potential coverage gaps. Two areas we pay particular attention to are replacement cost estimates and water backup coverage.
Even homeowners with substantial dwelling coverage can have limitations they don't realize exist.
Here are seven areas we believe New Jersey homeowners with high-value properties should review.
Not Sure Your Home Is Properly Insured?

What Is Considered a High-Value Home for Insurance Purposes?
There's no single definition of a high-value home that applies to every insurance company.
Some insurers offer specialized homeowners policies for properties with reconstruction costs of $1 million or more, while others use different eligibility requirements.
For this article, we're focusing on New Jersey homes valued between approximately $1 million and $3 million.
One important distinction: Your home's market value and its replacement cost are not the same thing.
Market value is what someone might pay to purchase your property. Replacement cost is the estimated expense to rebuild the home using comparable materials and construction methods at today's prices.
The National Association of Insurance Commissioners (NAIC) explains the difference between replacement cost and actual cash value, including why reconstruction costs can differ from market values.
That distinction brings us to the first coverage issue.
1. Is Your Dwelling Coverage Based on an Accurate Replacement Cost Estimate?
This is one of the first things we review when evaluating a homeowners insurance policy.
Your dwelling coverage, commonly called Coverage A, helps repair or rebuild your home following a covered loss, subject to the terms and limits of your policy.
But how was that coverage amount determined?
Insurance companies use replacement cost estimating tools that consider factors such as:
Square footage and construction type
Roofing materials
Kitchens, bathrooms, and custom finishes
Hardwood flooring and architectural details
Local construction and labor costs
Renovations and additions
What We Look for at OIA
When reviewing homeowners policies, we've identified discrepancies between existing dwelling coverage limits and the reconstruction estimates developed during our review.
That doesn't automatically mean the existing policy is inadequate. Different insurance companies may calculate reconstruction costs differently, and estimates can change when property details are updated.
However, when we see a meaningful difference, it's something we want to investigate rather than simply accept the existing coverage amount.
For example, a home might have $1.2 million in dwelling coverage, but an updated reconstruction estimate could indicate a rebuilding cost of $1.5 million.
That $300,000 difference deserves attention.
It's also important to review whether the policy offers extended or guaranteed replacement cost coverage, how that protection works, and what conditions apply.
OIA's Recommendation: If you've completed major renovations or haven't reviewed your dwelling coverage recently, ask your insurance agent to revisit the replacement cost estimate.

2. Is Your Water Backup Coverage Enough for Your Home?
This is another area we pay close attention to when reviewing homeowners insurance.
Many New Jersey homeowners have beautifully finished basements that include family rooms, home offices, bathrooms, entertainment areas, and expensive furniture.
But what happens if a sewer backs up or a sump pump overflows?
Standard homeowners insurance policies commonly exclude water backup unless coverage is added through an endorsement or included in an enhanced policy.
Even when coverage exists, the limit may be much lower than the homeowner expects.
Consider This Example
You own a $1.8 million home with a finished basement.
A covered sewer backup damages the flooring, drywall, cabinetry, and furniture.
The total covered damage is $65,000.
However, your policy only provides $10,000 in water backup coverage.
Depending on the policy terms and applicable deductible, you could be responsible for approximately $55,000 or more.
That's a significant out-of-pocket expense, especially when additional coverage options may have been available.
This is a hypothetical example for illustration, not an actual OIA client claim.
What We Look for at OIA
Water backup limits are one of the items we specifically review with homeowners.
A $10,000 or $25,000 limit might be appropriate for some properties, but it may not be enough for a home with an extensively finished basement.
We also look at whether higher limits are available and what the endorsement actually covers.
Keep in mind that water backup, sudden plumbing leaks, seepage, and flooding are different insurance exposures. Coverage for one doesn't necessarily mean coverage for the others.
Homeowners should also consider underground service line coverage, which addresses certain covered damage to buried utility lines rather than simply water backing up inside the home.
OIA's Recommendation: Review your water backup limit based on the potential cost of damage to your basement, not simply the default amount offered by your insurance company.
Is Your Current Homeowners Coverage Keeping Up With Your Home?
If you haven't reviewed your policy recently, it may be worth taking another look. OIA can help you evaluate your dwelling coverage, water backup limits, and other potential gaps.
Is Your Home Properly Insured?
Your home's value and insurance needs may have changed. OIA can help review your current coverage and identify potential gaps before a claim occurs.
3. Are Your Jewelry, Watches, and Other Valuables Properly Insured?
A common misconception is that having a high personal property limit means everything you own is fully insured.
Unfortunately, that's not always the case.
Homeowners policies frequently contain special limits for certain categories of property, particularly jewelry, watches, and other valuable items.
For example, you might have $500,000 in personal property coverage but only a limited amount available for jewelry stolen during a burglary.
Depending on the insurance company, you may be able to schedule individual items or obtain broader valuables coverage.
This is particularly important if you own:
Engagement rings and other valuable jewelry
Luxury watches
Fine art and antiques
Collectibles
Other high-value personal belongings
It's worth reviewing the applicable limits, covered causes of loss, valuation provisions, and deductibles.
OIA's Recommendation: Don't assume your personal property limit provides adequate protection for every valuable item. Review your policy's special limits and consider scheduling items where appropriate.
We've covered this topic in greater detail in our article on scheduled jewelry and valuables insurance.
4. Do You Have Enough Personal Liability and Umbrella Insurance?
Homeowners insurance isn't only about protecting the physical property.
It also provides personal liability coverage for certain claims involving bodily injury or property damage for which you're legally responsible.
Consider a situation where a guest is seriously injured on your property and alleges negligence.
A substantial injury claim could exceed the liability limit on your homeowners policy.
That's where personal umbrella insurance may help.
An umbrella policy can provide additional liability protection above eligible underlying policies, subject to its terms, exclusions, and required underlying limits.
For homeowners with substantial assets, it's worth reviewing how much liability protection they currently carry.
The appropriate amount depends on more than the value of the house. Other assets, vehicles, rental properties, household activities, and personal exposures should be part of the discussion.
OIA's Recommendation: Review your homeowners liability limits alongside your auto insurance and umbrella coverage. These policies should be evaluated together rather than individually.
5. Would Your Policy Cover the Cost of Temporary Housing After a Major Loss?
Imagine a fire causes significant damage to your home.
The repairs could take many months, particularly if the property has custom finishes, specialized materials, or extensive reconstruction requirements.
Where would you and your family live during that time?
Additional Living Expense coverage, commonly included under Coverage D, may help pay necessary increases in living expenses when a covered loss makes your home uninhabitable.
However, policies can have different dollar limits, time restrictions, and requirements.
For a homeowner accustomed to a larger property, finding suitable temporary accommodations could be expensive.
The NAIC provides a helpful explanation in its article, What Are Additional Living Expenses and How Can Insurance Help?.
OIA's Recommendation: Review both the amount of additional living expense coverage available and any time limitations. Consider what suitable temporary housing might realistically cost while your home is being repaired.
6. Does Your Insurance Account for Building Code Upgrades?
New Jersey has many beautiful older homes, particularly in established communities such as Westfield, Summit, Cranford, and surrounding areas.
Older homes can have unique architectural features, construction methods, and building systems.
If a covered loss damages part of your home, rebuilding may involve complying with current building codes.
Those requirements can create additional expenses beyond simply replacing what was damaged.
Ordinance or law coverage may help address certain increased costs associated with building code enforcement following a covered loss.
The amount and scope of this protection vary by policy.
OIA's Recommendation: If you own an older or extensively customized home, review your ordinance or law coverage and determine whether higher limits are available.
7. Do You Understand Your Deductibles and Policy Exclusions?
Two homeowners policies can have similar dwelling limits but respond very differently to the same loss.
One reason is the deductible.
For example, a homeowners policy might have a $2,500 standard deductible but a separate 2% wind or hail deductible.
If the percentage deductible is calculated using a $1.5 million dwelling limit, the deductible would be $30,000.
That's a substantial difference.
Homeowners should review:
Standard policy deductibles
Wind, hail, or named storm deductibles
Flood exclusions
Water damage limitations
Roof settlement provisions
Other applicable exclusions or coverage restrictions
This is particularly important for properties near the New Jersey coast, but inland homeowners should also understand their policy terms.
Remember, standard homeowners insurance generally doesn't cover flood damage. Separate flood insurance may be needed, even when the property isn't located in a designated high-risk flood zone.
OIA's Recommendation: Don't compare homeowners policies based on premium alone. Review the deductibles and exclusions so you understand your potential out-of-pocket expenses following a loss.
Does a $2 Million Home Need Specialized High-Value Homeowners Insurance?
Not necessarily.
Some homeowners with properties valued at $1 million to $3 million may be well served by a traditional homeowners policy with appropriate limits and endorsements.
Others may benefit from a specialized high-value homeowners policy.
Companies such as Chubb, Travelers, and AIG offer homeowners insurance solutions for different property characteristics and coverage needs, subject to underwriting eligibility and product availability.
Depending on the policy, specialized coverage may offer features such as broader replacement cost provisions, enhanced water damage protection, higher available limits, or additional claims services.
The important thing is to compare the actual coverage rather than assume one type of policy is automatically better.
As an independent insurance agency, OIA can help homeowners evaluate available options from the insurance companies we work with.
High-Value Homeowners Insurance Review Checklist
If you own a high-value home in New Jersey, here are seven questions worth discussing with your insurance agent:
Is my dwelling limit supported by an accurate reconstruction cost estimate?
Is my water backup coverage appropriate for my basement and other exposures?
Are my jewelry, watches, artwork, and valuables adequately protected?
Have I reviewed my personal liability and umbrella insurance limits?
Do I understand my additional living expense coverage?
Does my policy include appropriate ordinance or law coverage?
Have I reviewed my deductibles, exclusions, and coverage limitations?
If you aren't sure about several of these questions, that's a good reason to schedule a coverage review.

Frequently Asked Questions About High-Value Home Insurance in NJ
How much homeowners insurance do I need for a $2 million home in New Jersey?
Your dwelling coverage should generally be based on the estimated cost to rebuild your home, not its market value. A $2 million home could have a reconstruction cost above or below $2 million, depending on its construction, finishes, location, and other characteristics.
Is high-value homeowners insurance more expensive?
It can be, but premiums depend on the property's characteristics, coverage selections, deductibles, location, and claims history. A specialized policy may offer broader protection, so it's important to compare coverage alongside price.
Does homeowners insurance cover water damage in a finished basement?
It depends on what caused the damage and the terms of your policy. Sudden accidental plumbing damage, sewer backup, groundwater seepage, and flooding are treated differently. Water backup often requires specific coverage and may be subject to a separate limit.
How often should I review my high-value homeowners insurance?
OIA recommends reviewing your coverage at least annually and whenever you complete significant renovations, acquire valuable possessions, or experience major changes in your insurance needs.
