What Does Homeowners Insurance NOT Cover in Texas?

Standard Texas homeowners insurance covers a defined set of perils — fire, wind, hail, lightning, theft, and vandalism among them. What it does not cover is a longer list than most homeowners realize, and the gaps that cause the most financial damage are almost never the obscure ones. They are the common, predictable losses — flooding, sewer backup, termite damage — that Texas homeowners discover are excluded only after a claim is filed and denied.

This guide applies to Texas homeowners across Houston and surrounding areas — Katy, Cypress, Sugar Land, Pearland, The Woodlands, Friendswood, League City, Humble, and Baytown — where TWFG Elkhalil Insurance works with many of our clients. As a Houston-based independent broker who reviews homeowners policies regularly, the gap I see most often is flood — followed closely by sewer backup and inadequate coverage for high-value personal property.

Exclusion 1: Flood Damage

Flood damage is the most important exclusion in Texas homeowners insurance — and the one that has caused the most financial hardship for Houston-area homeowners. Every standard Texas homeowners policy contains a written flood exclusion. The exclusion applies regardless of the cause — hurricane, tropical storm, extreme rainfall, bayou overflow, or storm surge. If water enters the home from the outside and rises from the ground up, the homeowners policy pays nothing.

What "flood" means for purposes of the exclusion

The flood exclusion applies to water that enters a home as a result of surface water, overflow of a body of water, mudslide, or water that backs up through a sewer or drain as a result of flooding. It does not apply to sudden and accidental water damage from within the home — a burst pipe, an overflowing appliance — which is generally covered. The distinction is whether the water originated inside the home or outside of it.

Why the exclusion matters specifically in Houston

Houston is one of the most flood-prone major cities in the United States. According to the National Weather Service, Hurricane Harvey caused $125 billion in damage across the greater Houston area in 2017 — much of it uninsured because the affected homeowners did not have flood coverage. According to FEMA, over 40% of flood claims nationally come from properties outside high-risk flood zones — meaning flood zone designation is not a reliable proxy for flood risk, particularly in Houston's flat, clay-soil watershed.

The fix: a separate flood insurance policy

Flood coverage requires a completely separate policy — either through the NFIP or a private flood carrier. The NFIP has a 30-day waiting period before coverage activates, meaning it cannot be purchased once a storm is approaching. The right time to purchase flood insurance in Texas is before June 1 — the start of Atlantic hurricane season. Read our full guide on whether homeowners insurance covers flood damage for a complete explanation.

Exclusion 2: Sewer and Drain Backup

Sewer and drain backup is one of the most common water damage claims in Texas — and one of the most frequently denied, because it is excluded from standard homeowners policies by default.

What sewer and drain backup damage looks like

Sewer backup occurs when municipal sewer lines become overwhelmed during heavy rainfall — which happens regularly in Houston — and sewage reverses direction and enters a home through floor drains, toilets, or sinks. Drain backup occurs when a home's interior drainage system becomes blocked and water backs up from within the plumbing. Both events can cause significant property damage — sewage-contaminated water that reaches flooring, drywall, and personal property creates both structural and health-related remediation requirements.

Why sewer backup is excluded

Standard homeowners policies cover sudden and accidental internal water damage — a burst pipe, a failed appliance connection — but exclude damage from water or sewage that backs up through a drain or sewer. This exclusion is separate from and in addition to the flood exclusion, meaning sewer backup damage can be denied even when the cause is a heavy rainstorm rather than a flood event per se.

The fix: a water backup endorsement

A sewer and drain backup endorsement — also called a water backup endorsement — adds coverage for this specific loss type to your homeowners policy. It is typically available for $50–$150 per year in additional premium and is among the highest-value endorsements available to Houston-area homeowners given the frequency of heavy rainfall and sewer system stress in the market.

Exclusion 3: Earthquake Damage

Standard Texas homeowners policies exclude earthquake damage. Texas has historically had low seismic activity outside of West Texas, but induced seismicity from oil and gas operations — particularly in the Permian Basin and in areas around Dallas-Fort Worth — has increased earthquake frequency in certain parts of the state over the past decade.

For most Houston-area homeowners, earthquake risk is low enough that a standalone earthquake policy or endorsement is not a high priority. For homeowners in areas with documented recent seismic activity — or those with high-value homes where even a low-probability loss would be catastrophic — an earthquake endorsement is worth evaluating.

The fix

A separate earthquake endorsement or policy. Most Texas homeowners in the Houston market do not carry this — it is a lower-priority gap compared to flood and sewer backup. Discuss with your broker whether your specific location warrants the addition.

Exclusion 4: Mold Damage

Mold coverage in Texas homeowners policies is limited and conditional. The outcome depends on what caused the mold and how quickly it was discovered.

When mold damage is covered

If mold results directly from a covered sudden and accidental loss — a burst pipe that is discovered and reported promptly — most Texas homeowners policies will cover mold remediation as part of the water damage claim. The key conditions are that the underlying loss was covered and that the mold developed in a reasonable timeframe from the covered event.

When mold damage is not covered

Mold resulting from long-term moisture intrusion, humidity, flooding, or deferred maintenance is excluded. If a slow plumbing leak goes undetected for months and generates mold behind a wall, the claim will typically be denied because the underlying cause — a slow leak — is considered a maintenance issue rather than a sudden and accidental loss. Mold resulting from flood damage is also excluded, because the underlying flood event is excluded.

The fix

Mold is partially preventable through home maintenance — monitoring for moisture intrusion, maintaining humidity levels, and addressing any water damage immediately. Some carriers offer mold endorsements that expand coverage beyond the default, but these vary significantly in scope. Preventing mold through maintenance is more reliable than insuring against it after the fact.

Exclusion 5: Pest and Termite Damage

Termite damage, rodent infestations, bed bugs, and all other pest-related damage are excluded from standard homeowners insurance in Texas. Insurers treat pest prevention as an owner maintenance responsibility — damage from pests that were not prevented or treated is not an insurable sudden and accidental loss.

Why this matters specifically in Texas

Texas has one of the highest subterranean termite infestation rates in the country — the humid Gulf Coast climate creates favorable conditions for termite activity across Houston, Galveston County, Fort Bend County, and surrounding areas. According to the Texas Department of Agriculture, termite damage costs Texas homeowners hundreds of millions of dollars annually. None of this damage is covered by homeowners insurance.

The fix

A termite bond — a service agreement with a pest control company that provides annual inspections and treatment — is the most common protection mechanism for Texas homeowners. Some termite bonds include repair coverage for termite damage discovered during the bond period. This is not insurance — it is a service contract — but it provides the only meaningful financial protection against termite damage for Texas homeowners.

Exclusion 6: Normal Wear and Tear

Homeowners insurance covers sudden and accidental damage — not gradual deterioration over time. Roof degradation over 20 years, foundation settling and cracking over decades, appliance failure from age, and HVAC systems that wear out are all maintenance issues excluded from coverage.

How wear and tear affects claims for covered losses

The wear and tear exclusion extends beyond just denying claims for gradual deterioration. If a covered event — a hailstorm, a fire — causes damage to a component that was already significantly deteriorated due to age or lack of maintenance, the insurer may reduce the claim payout based on the pre-existing condition. A 25-year-old roof that sustains hail damage may receive an actual cash value settlement — accounting for depreciation — rather than a full replacement cost settlement if the policy form allows it.

The fix

Ongoing home maintenance is the only answer for wear and tear — it is not insurable. However, selecting a replacement cost policy form rather than an actual cash value policy minimizes the impact of depreciation on covered losses. Confirm with your broker whether your policy settles structure claims on a replacement cost or actual cash value basis.

Exclusion 7: High-Value Items Above Policy Sublimits

Standard Texas homeowners policies set sublimits on specific categories of high-value personal property — meaning the policy covers those items only up to a fixed dollar cap, regardless of their actual value.

Common sublimit categories in Texas homeowners policies

Item Category	Typical Sublimit	Coverage Gap Example
Jewelry	$1,500–$2,500 total	$10,000 engagement ring stolen — policy pays $1,500
Firearms	$2,500 total	$15,000 gun collection stolen — policy pays $2,500
Art and collectibles	$2,500 or less	$25,000 painting destroyed in fire — policy pays $2,500
Electronics	Often $5,000	High-end home theater stolen — partial coverage only
Silver and gold	$2,500 total	Inherited silver collection — covered only to sublimit

The fix: a scheduled personal property endorsement

A scheduled personal property endorsement — sometimes called a floater — allows you to list specific high-value items at their full appraised or agreed value, insured separately from the standard personal property limit. Scheduled items are typically covered on a broader basis than standard personal property — often including accidental loss, which standard policies do not cover. The annual premium for scheduling an item is typically 1–2% of the item's value per year.

Exclusion 8: Pool Liability Above Standard Limits

Your homeowners liability coverage does extend to pool-related injuries — if a guest is injured in your pool, your personal liability coverage pays for their medical bills and your legal defense up to your policy limit. However, standard homeowners liability limits — typically $100,000–$300,000 — can be exhausted quickly in a serious drowning or near-drowning claim involving a child.

The pool liability gap in Texas

Texas has one of the highest per-capita pool ownership rates in the country. A drowning claim involving a child can generate a lawsuit well in excess of a standard homeowners liability limit. Additionally, Texas courts have recognized attractive nuisance doctrine — meaning a homeowner can be held liable for injuries to children who access a pool without explicit invitation if the pool was not properly secured.

The fix: a personal umbrella policy

A personal umbrella policy adds $1 million or more of liability protection above your homeowners liability limits. For Texas homeowners with pools, teen drivers, or other elevated liability exposures, umbrella insurance is one of the most cost-effective risk management tools available — typically $160–$300 per year for $1 million in additional coverage.

Exclusion 9: Home-Based Business Property and Liability

If you work from home, your homeowners policy provides very limited coverage for your business activities — and in some cases, none at all.

What homeowners insurance does not cover for home-based businesses

• Business equipment above a small personal property sublimit — typically $2,500 or less
• Business liability — if a client visits your home office and is injured, the homeowners policy may exclude coverage because the incident is business-related
• Professional liability — if a client claims your work caused them financial harm
• Business inventory stored at home — products, materials, or equipment held for sale

The fix

A home business endorsement adds expanded coverage for business property and business liability to your homeowners policy — appropriate for many small home-based operations. For businesses with meaningful revenue, client visits, or professional liability exposure, a standalone Business Owners Policy (BOP) provides complete commercial coverage for the home-based business context.

Exclusion 10: Vacant Home Damage

Most Texas homeowners policies contain a vacancy clause that limits or eliminates coverage when the home has been unoccupied for more than 30–60 consecutive days — the specific threshold varies by policy and carrier.

When vacancy exclusions apply

• A second or vacation home left unoccupied between visits
• A home undergoing extended renovation that the owner is not living in
• A home inherited and awaiting sale
• A rental property between tenants for more than 30–60 days
• A home left during an extended stay elsewhere — travel, eldercare, medical recovery

The fix

Notify your broker any time your home will be unoccupied for more than 30 days. A vacancy endorsement can maintain coverage during the vacancy period. For homes vacant for extended periods — 90 days or more — a standalone vacant property policy provides dedicated coverage for the unoccupied property's specific risk profile.

What to Do About These Gaps — Priority Action List

Not every exclusion creates equal risk for every homeowner. The priority of each fix depends on your home's location, features, and your personal situation. The following framework applies to most Houston-area homeowners.

Priority 1: Add flood insurance (non-negotiable in Houston)

For any Houston-area homeowner — regardless of flood zone designation — flood insurance is the most financially important gap to close. Harvey demonstrated that Zone X properties flood. NFIP and private flood options are available. Purchase before June 1 to avoid the 30-day waiting period. Read our guide on flood insurance outside a flood zone.

Priority 2: Add a water backup endorsement

For Houston-area homeowners — where sewer system stress during heavy rainfall is common — a water backup endorsement at $50–$150/year is among the highest-value additions available. This should be confirmed at every renewal.

Priority 3: Add a personal umbrella policy

For homeowners with pools, teen drivers, rental properties, or significant assets, a personal umbrella policy adds $1 million or more of liability protection above homeowners limits for $160–$300/year. Read our guide on umbrella insurance in Texas.

Priority 4: Schedule high-value personal property

If you own jewelry, firearms, art, collectibles, or musical instruments with total value above $5,000, review your policy's sublimits and add a scheduled endorsement for items that would not be fully covered by default.

Priority 5: Annual coverage review with your broker

Policy exclusions, endorsement options, and your personal coverage needs change over time. An annual 30-minute review with your broker — at every renewal — is the most reliable way to confirm your coverage matches your current situation.

Frequently Asked Questions

Final Thoughts

A Texas homeowners policy is not a comprehensive safety net for every loss a home might experience. It is a defined contract that covers specified perils and excludes others — and the exclusions that cause the most financial damage in Texas are the ones that are most predictable: flood, sewer backup, termite damage, and losses that exceed sublimits on high-value items.

The case study in this guide — $38,400 in uninsured sewer backup damage that a $95/year endorsement would have covered — is not unusual. It reflects what happens when homeowners don't know what their policy excludes and brokers don't proactively discuss the gaps. Reviewing what your policy does not cover is not a one-time task. It is an annual conversation worth having at every renewal.
