Does Home Insurance Cover a Burst Pipe?
Usually yes, the sudden water damage is covered, but damage from a slow leak you ignored, or the pipe itself, often isn't.

What decides this is how the pipe failed. A frozen pipe that splits open in winter is a sudden burst, and the water damage is covered under dwelling coverage, the part of your policy that pays to repair your house. A slow leak behind a wall that you never fixed is treated differently, since insurers trace that damage to neglect and exclude it. The pipe itself usually isn't covered either, because policies pay for the water damage, not the worn-out part that failed. Your declarations page will show your dwelling coverage limit and your deductible.
The deductible that applies before coverage starts
Two policies with the same dwelling limit can leave you paying very different amounts before coverage kicks in. Comparing quotes now, before closing, shows what you'd actually owe if a pipe burst the week you move in.
What does the insurance actually pay for after a burst pipe
Once the claim is approved, coverage usually extends past the obvious part. Drying out the house, tearing out soaked drywall or flooring, and repainting are typically covered under dwelling coverage, the same part of your policy that would pay to rebuild the structure after a fire. If the water damaged furniture, a rug or electronics, that falls under personal property coverage instead, which is a separate limit listed on your declarations page.
Mold is where this gets narrower. Most policies cover mold if it shows up as a direct result of the burst pipe and you reported the damage quickly. Let the leak sit for a few weeks before anyone notices, and the insurer has grounds to call the mold a maintenance issue rather than sudden damage. Some policies cap mold remediation at a few thousand dollars regardless of the cause, so it's worth checking whether your policy has that kind of sublimit before you need it.
If the house is unlivable while repairs happen, loss of use coverage pays for a hotel or a rental and for meals above what you'd normally spend. This only applies when the damage is covered in the first place. A sudden burst qualifies. A leak that was ignored for months doesn't.
One more thing worth checking before closing is whether the house has been vacant. Some policies limit or suspend water damage coverage after a set number of days with nobody living there. A newly built or recently vacated house can fall into that gap right when you need coverage to start. The binder your lender wants is proof the policy is active, but reading what triggers and what excludes coverage matters more than having the paperwork on time.
What happens if the burst pipe isn't found right away
A pipe can fail behind a wall or under a slab and run for hours before anyone notices. The length of time between the pipe failing and someone finding it matters more than people expect. Insurers look at how fast the water was discovered and reported. A pipe that bursts while you're home, gets shut off, and gets reported that day is a clean claim. The same pipe, leaking into a crawlspace of a house you just closed on and haven't fully moved into yet, is harder to place.
Move-in timing matters for this reason. If nobody is checking the house daily during the first weeks after closing, a leak can run far longer than it would in a house someone lives in full time. The insurer isn't trying to catch you out. The claims adjuster has to figure out whether the damage matches a sudden event or built up slowly, and an unoccupied house makes that harder to tell either way.
Document the house at closing if you can. Photos of the pipes you can see, the water heater, and areas prone to leaks like under sinks and around the washing machine connection are worth having. If a pipe does fail in the first month, a record of its condition at closing helps show the failure was sudden rather than something that had been dripping for a while before you owned the place.
Shutting off the water at the main valve when nobody is going to be in the house, even for a few days during the move, limits how much a burst pipe can do before anyone's there to catch it. It won't prevent a pipe from failing. It changes a flooded house into a smaller repair, and it removes the question of how long the water was running unsupervised.
Before you sign the binder
Find your declarations page once the policy arrives. Check the dwelling coverage limit and the deductible, then check whether water damage coverage gets limited if the house sits vacant after closing.
