Nobody on a website can tell you what your policy covers, and anybody who says otherwise is guessing at your carrier, your endorsements and your deductible. What is worth knowing is the distinctions insurers commonly draw, because those decide most outcomes, and you can look them up in your own document tonight.
Almost every water-damage outcome turns on one question: was this sudden, or did it develop over time?
| Commonly treated more favourably | Commonly treated less favourably |
|---|---|
| A pipe that burst | A pipe that has been weeping for months |
| A supply connector that let go | A shower pan liner that failed gradually |
| A water heater that failed suddenly | Corrosion, rust and wear |
| An appliance hose that split | Seepage over a long period |
| Damage discovered immediately | Damage discovered long after it started |
Many policies treat the failed component and the damage it caused as two different things.
This surprises people more than anything else on the page. It is worth reading your policy for the specific words about tearing out and replacing part of the building to reach the failure. That clause is where a large part of a slab leak bill lives.
| Cost | Typically the larger question |
|---|---|
| Finding the leak | Small: a few hundred dollars |
| Repairing the pipe | Moderate |
| Getting to the pipe | Can be large, concrete, tile, cabinetry |
| Drying the structure | A separate trade, scaled to how long it ran |
| Mold remediation | Often separately limited in a policy, if covered at all |
| Replacing flooring and finishes | Frequently the largest single line |
| Damaged possessions | A different section of the policy again |
Reading that list explains why two people with the same leak have completely different experiences of claiming. The pipe is rarely the expensive part, what is on top of it is.
Stated as commonly, not universally, because your policy is the authority, not this page.
The sewer backup row catches people. It is frequently an optional add-on rather than part of a standard policy, and it is worth knowing which you have before a lateral fails.
A single leak can touch three or four different policies, and knowing which one covers what stops a good deal of wasted argument.
| Whose policy | Typically covers |
|---|---|
| Homeowner | The structure, and the owner’s own possessions |
| Renter | The tenant’s possessions, not the building |
| Landlord | The building, and often loss of rent |
| HOA master policy | Common elements, to whatever line the CC&Rs draw |
| Condo owner (HO-6) | What is inside that line, and often the deductible gap |
| Neighbour’s liability | Where their negligence caused it, and that is a real threshold |
The condo rows are where this gets genuinely complicated, because a master policy and a unit policy meet at a line defined in the governing documents rather than in either policy. If you own a condo, reading where the CC&Rs draw that line is more useful than reading either policy on its own — more at who is responsible.
We are licensed and insured plumbers, and this site is about leaks — finding the ones you cannot see and repairing them properly. Roughly half of what looks like a plumbing leak turns out not to be one, so the boundary is worth stating plainly.
Roof leaks are a roofer. Water under an air handler is an HVAC technician clearing a condensate drain. Water under an appliance is appliance repair. Drying, restoration and mold are separate trades again, and gas line repair is SoCalGas or a licensed gas fitter. We detect gas leaks, we do not repair gas lines.
The full list, with the trade to call for each, is on what we don’t do.
A frequent question, and the honest answer is that it varies.
| Cost | How it is commonly handled |
|---|---|
| Locating the leak | Sometimes covered, sometimes not — ask before assuming |
| Opening the building to reach it | Depends entirely on the tear-out wording |
| The plumbing repair | Often the least likely part to be covered |
| Drying and restoration | Commonly the largest covered portion |
| Replacing damaged finishes | Commonly covered, subject to the policy |
Worth asking your carrier before booking anything, because the answer sometimes changes the order you do things in. Detection is a flat $150 to $500 either way, and you get the written report regardless of who pays for the visit.
Not every leak should become a claim, and that is a judgement rather than a calculation.
We have no interest in the outcome either way, which is the only reason this section is worth reading. A repair gets quoted the same whether you claim or not.
A written report naming cause and location, the method used, what was ruled out, dated photographs, and an itemised quote — on every detection visit, whether or not you claim and whether or not you proceed with the repair. If your adjuster needs something specific, ask and we will provide it.

Cause, location and dated photographs in writing - what an adjuster actually works from.

Many policies cover the resulting damage more readily than the failed component itself. That means a claim can pay to replace your floor and not the pipe that ruined it. Look for the specific wording in your document.
The most consequential clause is the one about tearing out and replacing part of the building to reach a failure, because on a slab leak that access work is a substantial part of the bill. Read that clause specifically.
Because sudden and gradual are treated differently, and when you first noticed anything is part of establishing which you had. Write the date down while it is exact rather than reconstructing it later.
Usually its own section, usually limited, sometimes excluded. It is worth reading before you need it. It is also a reason to act quickly on a leak — remediation cost scales with how long the material stayed wet.
Frequently it is an optional endorsement rather than part of a standard policy. Worth checking which you have before a lateral fails rather than during.
We provide the technical facts: which line failed, where, by what mechanism, what was ruled out, and dated photographs. That is what an adjuster works from. We do not negotiate claims. That is a public adjuster or a broker.
Compare the likely covered amount against your deductible first. A repair below the deductible is not really a claim, and claims history affects renewal in ways that are easy to underestimate. A large loss is exactly what insurance is for.
Sometimes, sometimes not. Ask your carrier before booking, because the answer occasionally changes the order you do things in. Detection is a flat $150 to $500 either way and you get the report regardless.
Be straightforward about it. Guessing at the cause on a claim form is worse than describing what you observed and letting a technical report establish the mechanism, and a long-running leak is not automatically excluded in every policy.
