Whether the dwelling coverage on your policy would actually rebuild your house — and what a shortfall costs you at claim time. Planning estimate only, not an appraisal.
Your renewal jumped and the carrier said 'rates went up.' Here is what is actually driving it, how to tell whether yours outran your state's, and the four levers that genuinely move the number.
Flood and earth movement are excluded from every standard homeowners policy — and the clause that excludes them is written so a wind-and-water loss can be denied entirely. Here is what is out, and what fills each gap.
Non-renewed, cancelled, or declined: read the notice correctly, stop force-placed insurance, fix the reason code on it, and get the house insured again in 30 days.
The exact sequence to run when your house is damaged — mitigation, documentation, the claim call script, the adjuster visit, reading the estimate, and every escalation step in order.

From Home Insurance in Washington: What It Costs and What Actually Covers You
The most consequential number on your policy is your Coverage A limit, and the most common way it goes wrong is setting it to your home's market value or your mortgage balance.
Neither is right. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Market value includes land, which does not burn. Your mortgage balance is a financing number with no relationship to construction cost.
In Washington, this error runs in both directions at once, which makes it unusually confusing. Washington's median home price is about $617,990, one of the highest in the country, and a very large share of that is land value in the Puget Sound corridor. Insure to market value and you are likely paying for coverage you cannot use. Insure to your loan balance and you are likely badly under-covered. The only number that matters is the construction cost.
Rebuilding in Washington runs roughly $250 per square foot - the midpoint of a published $185 to $320 band covering materials, labor, and general contractor overhead and profit, excluding land.
On a 2,000 square foot home:
Take the band seriously:
Unlike most states in this dataset, Washington carries its own distinct cost band rather than sharing one with a group of neighbors - which is a modest point in the figure's favor. Still, the honest limitation: the source publishes cost bands, not surveyed averages, and no Washington building department or insurance regulator publishes a competing rebuild-cost survey to check it against. The $185-$320 spread is the honest width of this number.
Two other construction-cost series read Washington lower - $193 and $173 per square foot. Note that the $193 figure is the highest that series assigns to any state outside Hawaii, Alaska, California, New Jersey, New York, and Massachusetts, so it agrees that Washington is an expensive place to build. Both are also measuring a narrower quantity: they land near a $162 national figure that excludes general contractor overhead and profit. Rebuilding after a loss includes those, because you are hiring a contractor - often at post-disaster prices. That is why the higher figure is used here.
A 2,000 square foot Washington home costs about $500,000 to rebuild. The state's median home price is about $617,990.
If you insured that home to market value, you are carrying roughly $118,000 of dwelling coverage you cannot ever collect, because the lot survives every peril on the policy. You pay premium on it every year.
The reverse error is worse. A homeowner who bought at $617,990 with a $430,000 mortgage and insured to the loan balance is carrying $70,000 less than the rebuild cost and, as the next subsection shows, sits below the coinsurance threshold - which damages their small claims too.
Get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator. In Washington this is genuinely worth doing, because the market-value and rebuild-cost numbers are far enough apart that guessing goes wrong in both directions.
Most homeowners policies contain a coinsurance provision requiring you to insure the dwelling to at least 80% of its full replacement cost. Fall below that and the insurer does not merely cap your payout at your limit - it reduces every partial claim proportionally.
Work it on the example. Full replacement cost $500,000, so the 80% threshold is $400,000. Suppose you carry the $300,000 reference limit instead, and a fire does $80,000 of damage. Your limit is nearly four times the loss, so it feels safe. It is not:
You are $21,000 short on a claim comfortably inside your policy limit, entirely because Coverage A was set too low. None of it is visible until you file.
