You filed your homeowner’s insurance claim. You waited for the adjuster. And then the estimate came back — and it doesn’t come close to covering what it’s actually going to cost to fix your home. This scenario plays out constantly across Michigan, and it leaves homeowners in a difficult position: accept a payout that leaves real money on the table, or fight back without knowing how.
Here’s what you need to know.
Why Insurance Estimates Come in Low
Insurance adjusters are not adversaries, but they are working within a system designed to contain claim costs. There are several structural reasons why initial estimates routinely miss the mark:
- Desk adjusters. Increasingly, carriers use adjusters who review photos and satellite data remotely rather than conducting a thorough in-person inspection. What they can’t see, they can’t include.
- Outdated pricing data. Insurance pricing software is updated periodically, but material costs and local labor rates move faster — especially in Michigan’s post-pandemic construction market.
- Missed line items. A thorough scope of loss for even a moderate water or hail claim can run 50 to 100 line items. Adjuster estimates routinely omit code-required upgrades, incidental materials, and secondary damage that wasn’t immediately visible during a quick walkthrough.
- Scope limitations. An adjuster may scope only the visibly damaged area and miss adjacent materials that must be replaced to achieve a proper repair — for example, writing to patch drywall when the adjacent texture, insulation, or vapor barrier also needs attention.
What a Supplement Is — and How It Works
A supplement is an additional estimate submitted to your insurance carrier after the initial scope has been written. It’s not a dispute or a complaint — it’s a formal, line-item-supported request to include scope that was missed or priced incorrectly in the original estimate.
Supplementing a claim is a standard and legitimate part of the insurance restoration process. Experienced restoration contractors do it routinely. The key is documentation: every line item in a supplement needs to be tied to observable damage, code requirements, or material specs — not a gut feeling.
Xactimate: The Industry Standard
The vast majority of insurance carriers in Michigan — including State Farm, Allstate, Farmers, Foremost, Auto-Owners, and others — use a platform called Xactimate to price claims. Xactimate is a database-driven estimating tool that assigns a cost to each line item based on regional pricing updated monthly. When a contractor submits a supplement using the same platform and the same pricing methodology your carrier used, the conversation becomes a technical one about scope — not a subjective argument about money.
Contractors who know Xactimate can identify exactly where an adjuster’s estimate fell short and present a documented, comparable alternative. That’s a very different conversation from simply saying “your number is too low.”
Why Documentation and Scope of Loss Are Everything
The foundation of any successful supplement is documentation. Photos, moisture readings, material specifications, code references — all of it supports the case for why additional scope is warranted. If the documentation from mitigation and initial inspection is thorough, supplementing becomes much more straightforward. If it’s thin, you’re arguing without evidence.
This is one reason why the contractor you choose matters from day one. A contractor who documents comprehensively during mitigation is building the evidentiary record that supports a complete claim — not just doing cleanup.
Michigan Homeowners Have Real Leverage
Michigan homeowners have rights in the claims process. You have the right to get your own contractor’s estimate. You have the right to submit a supplement. You have the right to invoke the appraisal clause in your policy if a dispute cannot be resolved through negotiation — a process in which each party selects a qualified appraiser, and those appraisers work to reach agreement on the value of the loss.
None of these steps require an attorney or a public adjuster. A knowledgeable restoration contractor who understands the claims process can work alongside you through the supplement process directly.
How Phase III Construction Advocates Through the Process
Phase III Construction is a licensed Michigan restoration contractor — not a public adjuster. We don’t take a percentage of your claim. We perform the work and are paid from your insurance proceeds for the scope of work we complete.
What we do is document the full scope of your loss, write detailed estimates using Xactimate, and work directly with your carrier’s adjuster to make sure the approved scope reflects what it actually costs to restore your home to pre-loss condition. When the initial estimate is short, we prepare and submit supplements with supporting documentation. That’s a normal part of how insurance restoration works — and it’s something we do on every job where it’s needed.
Michigan homeowners shouldn’t have to fight their insurance company alone, and they don’t have to. If you’ve received an estimate that doesn’t add up, contact Phase III Construction for a free review. We’ll tell you honestly whether there’s scope that was missed and what the path forward looks like.
