Water damage claims are the most common homeowners insurance claim in Massachusetts. They're also the most commonly underpaid. Not because insurance companies are acting in bad faith — most of the time — but because the documentation most homeowners and contractors produce is insufficient for adjusters to approve the full scope.
Here's how the process actually works, what gets claims reduced, and what you can do from the first hour to protect your payout.
What Massachusetts homeowners insurance covers for water damage
Standard Massachusetts homeowners policies cover "sudden and accidental" water damage. That's the operative phrase. The covered causes typically include:
- Burst pipes from freezing or failure
- Ice dam infiltration — interior damage from water backing up under shingles
- Roof leaks from storm damage (wind, hail, ice)
- Appliance failures — water heater, washing machine, dishwasher
- Accidental overflow from plumbing fixtures
What's typically not covered: gradual leaks that developed over time, flooding from groundwater or overflowing bodies of water (that's flood insurance, a separate policy), and damage resulting from neglected maintenance.
The distinction between "sudden" and "gradual" is where many claims get contested. If an adjuster can argue the damage developed over weeks or months rather than from a discrete event, the carrier may reduce or deny the claim. Good documentation from the first day establishes the timeline clearly.
The role of the adjuster — and what they're actually doing
When you file a claim, your carrier assigns an adjuster. The adjuster's job is to verify that a covered event occurred, document the scope of damage, and produce an estimate for repair costs using Xactimate — the industry-standard estimating software.
The adjuster is not your advocate. They're also not necessarily your adversary. They're evaluating your claim based on the documentation in front of them. The quality of that documentation determines the outcome more than almost any other factor.
Adjusters see hundreds of claims. They're looking for specific types of evidence: moisture readings taken with a calibrated meter at the time of the event, photos of every affected area before any cleanup, documentation of what materials were damaged and their condition, and a scope of repairs written in line items that match Xactimate categories.
A contractor who doesn't know Xactimate will produce a scope that doesn't align with how adjusters read estimates. The result is a back-and-forth that delays your claim and often results in an underpayment.
Three reasons water damage claims get underpaid in Massachusetts
1. Poor documentation from the first visit
The single biggest factor. Photos taken after cleanup, no moisture readings, no drying logs, a scope that's written as a summary rather than line items. This gives adjusters room to reduce the approved scope significantly.
2. Delayed response
If you wait days before calling a contractor, the carrier may argue that some of the damage was preventable — that you didn't take reasonable steps to mitigate. Massachusetts insurance law requires policyholders to take reasonable steps to prevent further damage. Documenting that you called a contractor immediately after discovering the damage protects you against this argument.
3. The wrong contractor
A contractor who doesn't know how to document scope in Xactimate line items will leave money on the table. Not because they're dishonest — because they don't know how to translate the work into the language adjusters use. The result is a lower approved scope than the actual damage warrants.

What good documentation looks like — and what we produce
From the first site visit, we produce:
- Moisture readings: Taken with a calibrated meter at multiple points in every affected area, recorded with timestamps. This establishes the extent of moisture intrusion at the time of the event.
- Photo documentation: Every affected room, every affected surface, before cleanup begins. Ceiling stains, buckled flooring, wet insulation, damaged drywall — all documented.
- Drying logs: Daily moisture readings from when drying equipment is set to when materials reach acceptable moisture levels. Adjusters require these.
- Scope of repairs: Written in line-item detail, aligned with Xactimate categories. Every material, every labor item, specified by quantity and unit.
When we produce this documentation, adjusters have what they need to approve the full scope. When they don't have it, they estimate conservatively — and you pay the difference.
What to do if the adjuster's first offer is too low
Initial adjuster scopes are frequently incomplete. This isn't always intentional — they're working quickly, they weren't there when the damage was fresh, and their estimate may not account for all affected areas or all materials.
You can supplement a claim. A supplement is a written request to the carrier to review and approve additional line items that were missed in the initial scope. It requires documentation — photos, measurements, a written explanation of why the additional items are necessary.
We've supplemented claims in Quincy, Brookline, and Dorchester where the initial scope was 40–60% of the actual scope. The carrier approved the supplement in each case because we had the documentation to support it.
If you've already received an adjuster report and it feels low, call us. We'll review it and tell you whether supplementing is worth pursuing and what it would require.
Should you use a public adjuster?
Public adjusters work on your behalf — not the carrier's — and are paid a percentage of the final claim (typically 10–15%). They can be valuable for very large or complex claims where the initial carrier scope is significantly deficient.
For most standard water damage claims in Massachusetts, a contractor who documents thoroughly and knows how to supplement effectively is sufficient. Public adjusters add value when the scope dispute is significant enough to justify their fee — generally on claims over $30,000–$40,000 where there's a major gap between the initial scope and the actual damage.
