Concrete cancer is the informal name often used for alkali-silica reaction, or ASR. It can develop gradually inside concrete when reactive silica, alkalis, and moisture are present. Because the damage may progress over time rather than result from one sudden event, a claim can raise questions involving wear and tear, deterioration, defective materials, construction defects, earth movement, seepage, or other policy exclusions.
That does not mean every ASR-related claim will be denied. It means no buyer, seller, contractor, real estate broker, or online article can determine coverage without reading the actual policy and understanding the facts of the loss.
For background on the condition itself, see What Is Concrete Cancer in a Swimming Pool?. For a broader buyer and seller guide, read Concrete Cancer in Texas Pools.
TLDR
- Home insurance might cover some pool damage, but concrete cancer is not automatically covered.
- Texas policies vary in how they cover pools and other structures.
- Gradual deterioration, wear and tear, cracking, defective construction, seepage, or earth movement may be excluded.
- A separate sudden event may create a different coverage question from the underlying ASR.
- Owners should document the damage, report a potential claim promptly, and avoid permanent repairs until the insurer has had an opportunity to inspect.
Start With the Policy, Not an Assumption
Texas homeowners policies are not all identical. Some provide broader property coverage than others, and endorsements can add, remove, or modify coverage. The declarations page identifies the policy form, limits, deductibles, and endorsements, but the full policy explains what is covered and excluded.
The Texas Department of Insurance explains that property coverage for swimming pools varies among policies. A pool may fall under dwelling coverage, other-structures coverage, or a more limited category depending on how it is built and connected to the home.
Before assuming the pool is covered, ask the insurance agent or carrier:
- How is the pool classified under this policy?
- What property limit applies?
- Is replacement cost or actual cash value used?
- What deductible applies?
- Are there special pool exclusions or sublimits?
- Are the deck, equipment, plumbing, coping, and landscaping treated separately?
- Are construction defects, faulty materials, settling, cracking, seepage, or earth movement excluded?
Why Gradual Damage Creates a Coverage Problem
Home insurance is generally designed around covered events rather than the normal cost of maintaining, repairing, or replacing property as it ages. The Texas Department of Insurance explains that policies commonly do not cover wear and tear or damage that happens over time.
ASR can be difficult from a coverage standpoint because the reaction may develop slowly inside the concrete before visible cracking appears. The policy may treat the condition differently from sudden damage caused by a clearly identifiable event.
An adjuster may ask:
- When did the first visible cracking appear?
- Was the damage progressive?
- Was the pool already leaking?
- Were prior repairs attempted?
- Was defective aggregate or workmanship involved?
- Did soil movement contribute?
- Was there a separate sudden event?
- What part of the damage occurred during the policy period?
Those questions help the insurer decide whether the claim involves a covered loss, an excluded condition, or a combination of both.
What If a Sudden Event Damages an ASR-Affected Pool?
A pool can have an existing condition and later suffer separate damage from a sudden event. For example, a storm, falling object, fire, vehicle impact, or sudden plumbing failure could create a different claim question from the ASR itself.
The policy may distinguish between the excluded underlying condition and resulting damage caused by a covered event. The outcome depends on the wording of the policy, the sequence of events, and the evidence supporting the claimed cause.
This is one reason owners should avoid describing every form of damage as “concrete cancer” before professionals have investigated it. The label may be incomplete or inaccurate, and the actual cause of loss matters to the claim.
Could Faulty Materials or Construction Be Excluded?
Many property policies contain exclusions involving faulty, inadequate, or defective design, specifications, workmanship, construction, renovation, materials, or maintenance. The exact language varies.
If ASR developed because reactive aggregate or an unsuitable concrete mixture was used, the insurer may examine whether a defective-material or construction exclusion applies. At the same time, some policies distinguish between the defective component itself and separate resulting damage.
That distinction can become complicated. Owners dealing with substantial damage may need help from their insurance agent, adjuster, engineer, contractor, and an attorney experienced in property coverage disputes.
Could Cracking, Settling, or Earth Movement Be Excluded?
Pool damage may involve more than one cause. Central Texas soil movement, settlement, plumbing leaks, drainage, hydrostatic pressure, workmanship, and ASR can sometimes produce overlapping symptoms.
Policies often contain language involving settling, shrinking, bulging, expansion, cracking, or earth movement. Whether that language applies depends on what caused the damage and how the policy is written.
An engineering report can be important because an insurer should not have to guess whether the cracking resulted from ASR, soil movement, a plumbing failure, or another condition. The owner also needs an accurate diagnosis before deciding whether to challenge a coverage decision.
What About Water Loss and Gradual Seepage?
A leaking pool can damage the shell, plumbing, deck, soil, landscaping, or nearby improvements. Texas Department of Insurance guidance notes that home policies usually do not cover water damage from gradual leaks or seepage, although sudden and accidental water damage may be treated differently.
If a pool has been losing water for months or years, the carrier may ask when the owner first noticed the condition and what steps were taken to prevent further damage. A hidden plumbing failure discovered suddenly may present different facts from long-term seepage through recurring structural cracks.
Document water loss, leak-detection results, repair attempts, water bills, and dated photographs. Those records may help establish the timeline.
Does “Other Structures” Coverage Automatically Include the Pool?
Not always. Texas Department of Insurance materials explain that policies may cover detached structures, but pool property coverage varies by policy. An attached pool, detached pool, pool house, equipment enclosure, deck, or outdoor kitchen may be classified differently.
Even when a pool falls under a covered property category, the cause of loss must still be covered. Having a limit for other structures does not mean every type of damage to every structure will be paid.
What Should an Owner Do Before Filing a Claim?
Begin by gathering information without destroying evidence.
- Read the policy. Review the declarations, property coverages, exclusions, conditions, deductibles, and endorsements.
- Photograph and video the condition. Include close views and wider views showing the surrounding pool area.
- Gather prior records. Collect construction documents, repair invoices, warranties, inspection reports, engineering reports, and leak-detection findings.
- Create a timeline. Record when cracking, water loss, movement, or other symptoms were first noticed.
- Prevent additional damage. Take reasonable temporary steps when safe, but preserve evidence and avoid permanent repairs before speaking with the carrier.
- Contact the carrier or agent promptly. Ask how to report the claim and what documentation is required.
The Texas Department of Insurance recommends taking photographs before work begins and generally advises homeowners to speak with the insurance company before making permanent repairs.
Should You File a Claim Before Knowing the Repair Cost?
That decision depends on the severity of the damage, expected cost, deductible, policy language, and the owner’s claim history. A small cosmetic repair may cost less than the deductible. A structural pool loss can be much larger and may justify prompt notice even before the final scope is known.
Do not wait for every estimate if delay could affect the carrier’s ability to inspect the property or evaluate the claim. The National Association of Insurance Commissioners advises homeowners to notify the insurer promptly when filing a claim.
Owners can ask the agent how reporting an incident, making an inquiry, or formally opening a claim is handled by that company. The answer can vary.
What Happens After the Claim Is Filed?
The insurer may assign an adjuster, request photographs and records, inspect the property, ask for an engineering review, and obtain its own repair estimate. The company will then decide whether the policy covers all, part, or none of the claimed damage.
The Texas Department of Insurance explains that Texas insurers must acknowledge receipt of a claim within required timeframes and may request additional information before making a decision. The carrier determines whether the policy covers the damage based on the policy and facts.
The owner should keep a written log of:
- Claim number
- Names and contact information
- Dates of conversations
- Documents submitted
- Inspection dates
- Requests for additional information
- Coverage letters and estimates
What If the Claim Is Denied?
Read the denial letter carefully. It should identify the policy language and facts supporting the decision. Compare that explanation with the policy, engineering findings, and repair evidence.
Questions to ask include:
- What specific exclusion is being applied?
- Does the denial address every category of damage?
- Did the carrier consider a separate sudden event?
- Is the insurer disputing the cause, timing, or amount?
- Would additional engineering or testing change the analysis?
- Does the policy include appraisal, mediation, or other dispute procedures?
The Texas Department of Insurance can answer general insurance questions and accept complaints, but it explains that it cannot settle factual disputes or force payment unless the company has violated the law or policy terms.
Could a Builder Warranty or Other Claim Apply?
Insurance is only one possible source of recovery. Depending on the pool’s age, contracts, warranties, parties involved, and applicable deadlines, an owner may also investigate:
- Pool-builder warranties
- Concrete supplier or contractor claims
- Manufacturer warranties
- Home warranty or residential service contracts
- Legal claims involving construction or disclosure
A home warranty is not the same as homeowners insurance. Texas Department of Insurance guidance explains that residential service contracts may cover certain items that fail from normal wear and tear, and some contracts may offer pool coverage. The contract must be reviewed to determine what is actually included.
What Should Buyers Ask Before Purchasing a Home With a Pool?
A buyer should not wait until after closing to discover whether the pool is insurable or whether a known condition will be excluded.
Before the end of the option period, consider asking:
- Has the seller made any pool-related insurance claims?
- Were any claims denied or partially paid?
- Are engineering, testing, repair, or warranty records available?
- Will the buyer’s proposed insurer cover the pool?
- Are there special exclusions, sublimits, or inspection requirements?
- Will a known ASR condition affect eligibility or premium?
- Can the buyer obtain acceptable coverage before closing?
For help evaluating the pool itself, see Pool Inspection vs. Home Inspection.
Frequently Asked Questions
Does homeowners insurance automatically cover concrete cancer?
No. Coverage depends on the policy, cause of loss, exclusions, timing, and supporting evidence.
Is ASR usually considered gradual damage?
ASR often develops over time, which can lead insurers to examine exclusions involving deterioration, cracking, defective materials, construction defects, or seepage. The policy and facts control the decision.
Can a separate sudden event still be covered?
Possibly. A covered sudden event may create a different coverage question from the preexisting ASR. The insurer will evaluate the sequence of events and policy language.
Should I repair the pool before the adjuster visits?
Take reasonable temporary steps to prevent additional damage when safe, but document the condition and speak with the carrier before permanent repairs whenever practical.
Can a buyer obtain insurance on a home with known pool damage?
Possibly, but the insurer may require more information, exclude the condition, limit coverage, require repairs, or decline the risk. Buyers should investigate before closing.
Can the Texas Department of Insurance make an insurer pay?
TDI can answer questions and accept complaints, but it states that it cannot settle factual disputes or require payment unless the insurer violated the law or policy terms.
My Bottom Line
Home insurance may cover some forms of swimming-pool damage, but concrete cancer is not automatically covered. ASR can involve gradual deterioration, defective materials, cracking, seepage, movement, and other conditions that may fall within policy exclusions.
The strongest approach is to read the policy, preserve evidence, obtain a qualified diagnosis, report a potential claim promptly, and require the carrier to explain its decision using the actual policy language. Buyers should investigate insurability before closing rather than assuming a future claim will solve an existing pool problem.
