Your insurance renewal just went up. Here's what to do.

If your renewal arrived with a bigger number and no claim to explain it, you're not being singled out. Massachusetts premiums have been climbing because the cost of rebuilding has climbed, from materials and labor to the reinsurance that sits behind your policy, and because carriers have been approved for rate increases after filing with the Division of Insurance.

Those filings are public, which is the good news. The increase on your notice has a number behind it, and an office that reviewed it.

Almost nobody does this, and it's where the answer is. Your premium total is the headline. The changes in coverage are the story.

• Dwelling replacement cost. If this jumped well past the rate of construction inflation, it's driving your premium. It's also the number most worth questioning, because replacement cost should track what it would cost to rebuild your house, not its market value, and not your mortgage.
• Your deductible, and whether there's now a second one. The one to look for is a separate percentage wind or hail deductible. On a $600,000 dwelling, a 2% wind deductible is $12,000 out of your pocket before the policy pays a cent. If one was added or raised this year, that's a real change in what you're buying.
• Roof coverage. Whether the roof is insured at replacement cost or at actual cash value, its depreciated value. This is the most frequently changed item on Massachusetts renewals, and the change is usually in the fine print.
• Water backup, mould, and ordinance or law. Water backup coverage is inexpensive and covers the most common household claim there is. Ordinance or law coverage is what pays to rebuild an older home to current code, without it, you pay the difference.
• Renewal, or non-renewal? They look similar and they are not the same. A non-renewal has an effective date, and that date is a deadline.

The Decision That Actually Lowers the Bill

Of everything within your control, raising your deductible is the reliable lever. Going from a $1,000 to a $2,500 deductible commonly takes a meaningful bite out of the premium, because you're accepting more of the small-claim risk yourself.

Then ask for the discounts nobody offers. Bundling auto and home, a roof replaced within the last ten years, a monitored alarm, years without a claim, and in some cases credit-based insurance scoring. Ask your agent explicitly for the list their carrier offers, they can see it, and many won't raise it unprompted.

Do These Five Things This Week

1. Compare the Declarations Page to Last Year's

   Two years of documents side by side. Circle anything that changed beyond the premium.

2. Ask Your Agent, in Writing, What Changed

   “What changed in my coverage this year, and what is the dollar cost of each change?” Keep the reply.

3. Get Two Other Quotes

   An independent agent can quote several carriers at once. Compare declarations pages, not summaries.

4. Do the Arithmetic on Your Deductible

   In dollars, on a total loss. Then decide whether you can fund it.

5. If You're Non-Renewed, Don't Let the Date Pass

   The FAIR Plan, the state's insurer of last resort, takes homes that have been declined in the private market. (617) 723-3800.

What We're Doing About It

Insurance is the fastest-rising line on a Massachusetts homeowner's bill, and unlike your property tax, it doesn't come with a vote. So we're pushing on the parts that can be changed.

• Transparent rate filings. A plain-English summary of what a proposed increase does to a typical homeowner's premium, published before it's approved, not after.
• A stable FAIR Plan. It was built as the backstop for homes nobody else would insure, and enrollment has surged. A backstop that can't absorb the demand isn't a backstop.
• Credit where it's earned. Real premium reductions for homeowners who invest in a new roof, updated wiring, or storm protection. If mitigation lowers the risk, it should lower the bill.

You can't control the price of risk. You can control whether you shop it, and this is the one bill on a homeowner's list that still answers to shopping.
