Whether your homeowners insurance covers water damage depends almost entirely on how the water got in — not how much damage it caused. The short answer: sudden, accidental water damage (a burst pipe, a washing machine hose that let go, a dishwasher overflow) is almost always covered. Slow leaks, flooding from outside, and damage you could have prevented with basic maintenance usually are not. Understanding that one distinction before you file a claim can save you thousands of dollars and a lot of frustration.
The Core Rule: Sudden vs. Gradual
Insurance companies draw a hard line between two types of water damage.
Sudden and accidental damage happens in a moment — a supply line bursts while you’re at work, a pipe freezes and splits overnight, your water heater fails and dumps 50 gallons onto the utility room floor. Standard HO-3 homeowners policies (the most common policy type in South Dakota and across the country) cover this kind of loss, including the cost to tear out and dry affected materials and, in most cases, repair or replace the damaged structure.
Gradual damage is the slow drip under the kitchen sink that’s been rotting the cabinet floor for six months, the pinhole leak in a supply line that’s quietly wicking into the subfloor, the caulk around the tub that failed two years ago. Adjusters are trained to spot the difference — staining patterns, mold growth timelines, and the condition of surrounding materials all tell a story. If the damage looks like it developed over weeks or months, expect a denial on the grounds of “lack of maintenance” or “long-term seepage.”
A practical test: If you could have noticed and fixed it before major damage occurred, your insurer will likely argue you should have.
What’s Typically Covered — and What Isn’t
Here’s how most standard policies break down:
Usually covered:
- A pipe that bursts due to freezing (provided the home was heated — policies often require you to maintain a minimum temperature)
- Accidental overflow from a plumbing fixture (toilet, tub, sink)
- Appliance failures (washing machine, dishwasher, water heater) when the failure is sudden
- Roof damage from a storm that allows rain to enter — the resulting interior water damage is typically covered under your dwelling coverage
- Accidental discharge from a fire-suppression sprinkler system
Usually NOT covered:
- Flooding — water that enters from outside (rising rivers, storm surge, heavy rain overwhelming drainage) is excluded from standard homeowners policies. You need a separate NFIP or private flood policy for that. In Sioux Falls, where spring snowmelt and severe thunderstorms can overwhelm storm sewers quickly, this gap is worth knowing about.
- Sewer or drain backup — this is also excluded by default, though many insurers offer it as an affordable endorsement (add-on). If you’ve ever had sewage back up through a floor drain, you know why it’s worth the extra premium.
- Gradual leaks and seepage, as described above
- Damage caused by neglected maintenance (a roof that was already failing before the storm, a water heater that hadn’t been serviced in 15 years)
- Mold remediation, in many cases — some policies cover mold that results from a covered water loss, but only up to a sublimit (often $5,000–$10,000), and only if you took reasonable steps to dry things out promptly
What to Do the Moment You Discover Water Damage
How you respond in the first few hours affects both the physical outcome and your insurance claim. Here’s the sequence that matters:
- Stop the source. Turn off the water supply to the affected fixture, or shut off the main valve if you can’t isolate it. Your main shutoff is usually near the water meter — in most Sioux Falls homes, that’s in the basement utility area or crawl space.
- Document everything before you touch it. Walk through with your phone and record video. Get wide shots of every affected room, close-ups of standing water, and photos of the source (the broken pipe, the failed supply line, the appliance). This footage is your evidence.
- Call your insurance company or agent. Report the claim the same day if possible. Ask specifically: Is this loss covered under my policy? What is my deductible? Do I need to use a preferred vendor, or can I choose my own restoration contractor?
- Begin mitigation — but don’t demolish. You have a legal duty to mitigate further damage (your policy requires it), which means extracting standing water and moving wet belongings to dry areas. What you should NOT do is rip out drywall, pull up flooring, or discard damaged materials before an adjuster has seen them. Premature demolition can complicate your claim.
- Get a professional assessment. Water travels. What looks like a contained puddle in the laundry room may have wicked under the flooring into adjacent rooms, or migrated down a wall cavity to the level below. Moisture meters and thermal imaging cameras reveal what your eyes can’t.
The Mold Clock Is Already Running
This is the part most homeowners underestimate. Under the right conditions — warm temperatures, organic material like drywall paper or wood framing, and relative humidity above roughly 60% — mold can begin to colonize within 24 to 48 hours of a water event. Once it establishes, it spreads, and remediation becomes significantly more involved (and expensive) than simple drying.
South Dakota summers don’t help. A wet basement or crawl space in July is close to ideal conditions for rapid mold growth. If your water damage event happened more than 24 hours ago and the area hasn’t been actively dried, treat mold as a real possibility, not a hypothetical.
If mold is present or suspected, don’t run fans across affected surfaces — that can spread spores to unaffected areas. A restoration crew with proper containment protocols and air scrubbers handles this differently than standard drying.
How the Claims and Restoration Process Actually Works
Once you’ve filed your claim, here’s what a typical timeline looks like:
- Day 1–2: Adjuster is assigned. In straightforward cases, they may do a virtual inspection via photos you submit; larger losses typically get an in-person visit.
- Day 1–3 (simultaneously): A restoration company begins emergency services — water extraction, placement of industrial air movers and dehumidifiers, moisture mapping. Drying a structure to IICRC S500 standard typically takes 3–5 days, depending on materials and ambient conditions.
- Day 3–7: The adjuster reviews the scope of damage. A good restoration contractor will provide detailed documentation (moisture readings, equipment logs, affected square footage) that supports your claim.
- Week 2 and beyond: Once the structure is dry and the claim is approved, reconstruction begins — replacing drywall, flooring, cabinets, and any other structural elements that couldn’t be salvaged.
The restoration and the insurance process run in parallel, not sequentially. You don’t need to wait for a check before drying begins.
When to Call a Restoration Professional
Call a water damage restoration company — not just a plumber — when:
- There’s more than a small, contained puddle
- The water has been sitting for more than a few hours
- You can see water staining on walls, ceilings, or floors in rooms adjacent to the source
- The affected area includes carpet, hardwood, engineered flooring, or drywall
- You smell anything musty or earthy
- The water came from a sewage or drain backup (this is a biohazard situation requiring different protocols)
A plumber fixes the source. A restoration company addresses what the water did after it got there — and those are two very different scopes of work.
