Home Insurance: What's Covered, What's Not, and What to Ask

Most homeowners pay their insurance premium every year and never read their policy. Then a pipe bursts, a tree falls, or a storm blows through, and they discover their policy doesn't cover what they assumed it did.

Home insurance is not a blanket guarantee that your house will be made whole after any disaster. It's a contract with specific inclusions, exclusions, limits, and conditions. Understanding these details before you need to file a claim is the difference between financial recovery and financial ruin.

HO-3 vs. HO-5: The Two Policies That Matter

The insurance industry uses numbered policy forms. For homeowners, only two matter: HO-3 and HO-5.

HO-3 (Special Form). This is the standard homeowners policy and what roughly 80% of homeowners carry. It covers your dwelling on an "open peril" basis, meaning everything is covered unless the policy specifically excludes it. However, your personal belongings (furniture, electronics, clothing) are covered on a "named peril" basis, meaning only the 16 perils listed in the policy are covered. If your laptop gets damaged by something not on that list, you're out of luck.

HO-5 (Comprehensive Form). This is the premium option. Both your dwelling and your personal property are covered on an open peril basis. If it's not explicitly excluded, it's covered. HO-5 policies typically cost 5% to 10% more than HO-3 policies, and for most homeowners, the upgrade is worth it. If you own expensive electronics, jewelry, musical instruments, or collectibles, HO-5 closes the gaps that HO-3 leaves open.

Bottom line: If your insurer offers HO-5 and the price difference is manageable, take it. If you're on HO-3, understand that your stuff has less protection than your walls.

What Home Insurance Does NOT Cover

Here is where most homeowners get burned. These are the most common exclusions in standard home insurance policies:

Floods. Standard home insurance does not cover flood damage. Not from hurricanes, not from heavy rain, not from overflowing rivers. Flood coverage requires a separate policy, typically through the National Flood Insurance Program (NFIP) or a private flood insurer. NFIP policies cap at $250,000 for the dwelling and $100,000 for contents. If your home is worth more, you need supplemental private flood coverage. Even if you're not in a designated flood zone, about 25% of flood claims come from low-to-moderate risk areas.

Earthquakes. Not covered. You need a separate earthquake policy or an endorsement. If you live in California, the California Earthquake Authority (CEA) is the primary source. Earthquake policies typically carry high deductibles of 10% to 20% of the dwelling coverage limit.

Sewer and drain backup. If your sewer line backs up and floods your basement, your standard policy almost certainly excludes it. This endorsement typically costs $40 to $70 per year and covers $5,000 to $25,000 in damage. Given that sewer backup cleanup averages $7,000 to $10,000, this is one of the cheapest and most valuable endorsements you can add.

Maintenance and wear. Insurance covers sudden and accidental damage, not gradual deterioration. A burst pipe is covered. A pipe that has been leaking for six months and caused mold is not. Termite damage, rust, rot, and settling are all excluded.

Home business equipment. Most policies cap business property at $2,500. If you run a business from home with equipment worth more than that, you need a separate business property endorsement or a standalone business insurance policy.

Replacement Cost vs. Actual Cash Value

This is the single most important distinction in your policy, and most homeowners don't know which one they have until they file a claim.

Replacement Cost Value (RCV) pays to replace your damaged property with new items of similar kind and quality. Your five-year-old roof gets destroyed by hail, and the insurer pays for a new roof.

Actual Cash Value (ACV) pays the replacement cost minus depreciation. That same five-year-old roof? The insurer deducts five years of depreciation from the payout. On a $15,000 roof, that could mean receiving $8,000 to $10,000 instead of $15,000.

ACV policies are cheaper for a reason: they pay out significantly less. If you have an ACV policy on your dwelling, switch to RCV. The premium difference is typically 10% to 15%, and the payout difference in a serious claim can be tens of thousands of dollars.

Watch for a hybrid trap: some policies provide RCV for the dwelling but ACV for personal property. Read the declarations page of your policy. It will specify the valuation method for each coverage section.

Umbrella Policies: The Coverage Most People Skip

Your home insurance includes liability coverage, typically $100,000 to $300,000. If someone is injured on your property and sues you for $500,000, your policy pays up to its limit and you're personally responsible for the rest.

An umbrella policy provides an additional layer of liability coverage, usually in $1 million increments. A $1 million umbrella policy typically costs $150 to $300 per year. It covers liability claims that exceed your home or auto policy limits, and it covers some claims that those policies exclude entirely, such as libel, slander, and false arrest.

If you have assets to protect (a home, savings, investments), an umbrella policy is one of the best insurance values available. If you have a pool, a trampoline, a dog, or teenagers who drive, it moves from "good idea" to "essential."

How to Lower Your Premium Without Dropping Coverage

Cutting coverage to save money is the wrong approach. Here are ways to reduce your premium while maintaining the protection you need:

Raise your deductible. Moving from a $1,000 deductible to $2,500 can reduce your premium by 10% to 15%. This makes sense if you have an emergency fund and wouldn't file a claim for a $1,500 loss anyway. Small claims can raise your rates more than the payout is worth.

Bundle your policies. Carrying home and auto with the same insurer typically saves 5% to 15%. But always compare the bundled total against the best standalone prices for each. Bundling isn't automatically the cheapest option.

Improve your home's risk profile. A new roof, a monitored security system, smoke detectors, a water leak detection system, and updated electrical and plumbing can each earn discounts of 2% to 10%. Impact-resistant roofing can save 10% to 35% in hail-prone states.

Ask about every discount. Claims-free discounts, loyalty discounts, professional association discounts, senior discounts, and paperless/autopay discounts are all common. Insurers rarely apply them automatically. You have to ask.

Shop every two to three years. Loyalty to one insurer does not guarantee the best rate. Insurance companies adjust their risk models constantly. The company that was cheapest three years ago may not be cheapest today.

Five Questions to Ask Your Insurer Right Now

• Is my policy RCV or ACV for the dwelling? For personal property?
• What is my sewer/drain backup coverage, and what is the limit?
• What is my guaranteed replacement cost limit, and is there an extended replacement cost endorsement available?
• Are there any ordinance or law exclusions that would prevent me from rebuilding to current code?
• What discounts am I currently receiving, and which ones am I eligible for but not getting?

Bottom Line

Home insurance is not a set-it-and-forget-it product. Your policy has gaps, and those gaps are designed to limit the insurer's exposure, not to protect you. Know the difference between HO-3 and HO-5. Verify you have replacement cost, not actual cash value. Add sewer backup coverage. Consider an umbrella policy. And read your declarations page at least once a year. The 20 minutes it takes could save you five figures on a claim.
