When you file a property insurance claim, you are likely focused on one thing: getting your home or business back to its pre-loss condition. You pay your premiums under the assumption that if disaster strikes, the insurance company will cover the costs required to fix the damage. However, many policyholders soon encounter a frustrating hurdle. The adjuster arrives, surveys the scene, and then begins slashing the contractor’s estimate, claiming certain line items are “not reasonable” or “not necessary.”

This is where the battle lines are drawn. In the world of property restoration and insurance recovery, the “Reasonable and Necessary” clause is the most frequently contested territory. To the insurance company, “reasonable” often means “the cheapest possible way to hide the damage.” To a professional restorer and a savvy policyholder, “necessary” means “following the industry standards and building codes to ensure the structure is safe and sound.”

If you find yourself in a standoff with your carrier, you need more than just a frustration-filled phone call. You need a technical and legal framework to fight back. This guide will empower you to move beyond the adjuster’s subjective opinion and ground your claim in the objective reality of technical standards and code compliance. When you understand how to wield these definitions, you transition from a petitioner to a claimant with authority.

Defining ‘Reasonable’ and ‘Necessary’: The Contractual Reality

In most standard property insurance policies, the insurer agrees to pay the “reasonable and necessary” cost of repair or replacement. The problem is that these terms are rarely defined within the policy itself. This ambiguity is intentional; it gives the insurer room to interpret the scope of work through the lens of cost-containment rather than quality.

To win this argument, you must first understand how these terms are viewed in a legal context. “Reasonable” typically refers to the cost—ensuring that a contractor isn’t charging $500 for a hammer. “Necessary” refers to the scope—ensuring that the work being done is actually required to restore the property. When an insurer cuts your claim, they are often attacking the necessity of the work. They might claim that three days of drying was enough when the science dictates five, or that a certain building code upgrade isn’t required by the letter of the law.

As a Claims Advocate, I see adjusters use software like Xactimate to dictate what is “reasonable.” They argue that because the software lists a certain price, that is the ceiling. However, Xactimate is a tool, not a rulebook. It does not account for local labor shortages, the specific complexity of your unique architecture, or the stringent requirements of local building officials. Necessity is not determined by an algorithm; it is determined by the physical requirements of the building and the legal requirements of the jurisdiction.

Furthermore, you must look at your state’s specific insurance regulations. For example, if you are dealing with delays or unfair denials regarding the scope of work, understanding Texas Insurance Code 542.056 for property claims is essential. This code mandates specific timelines and standards for how insurers must acknowledge and process claims. If an insurer is arbitrarily denying necessary work without a reasonable basis, they may be in violation of these prompt-payment and fair-handling statutes.

The IICRC Defense: Standards Over Opinions

One of the most effective ways to seek insurance claim help is to stop arguing about “feelings” and start talking about “standards.” In the restoration industry, the gold standard is the IICRC (Institute of Inspection, Cleaning and Restoration Certification). Specifically, the S500 (Standard for Professional Water Damage Restoration) and the S520 (Standard for Professional Mold Remediation) are the industry benchmarks.

When an adjuster tells you that a piece of equipment isn’t “necessary,” they are usually making a subjective judgment call based on their company’s internal “best practices”—which are almost always designed to save the company money. In contrast, the IICRC S500 provides a mathematical formula for how many air movers and dehumidifiers are required based on the cubic footage of the room, the types of materials involved (Class 1, 2, 3, or 4 water intrusion), and the evaporation rate.

If your contractor has followed the IICRC S500, their scope of work is “necessary” by definition. The insurer cannot simply ignore these industry standards because they find them expensive. If they do, they are essentially asking the contractor to perform professional negligence. By documenting the claim using these standards, you shift the burden of proof back to the insurer. They must then explain why their arbitrary opinion is more valid than the recognized scientific standard for the industry.

Consider the data table above. If an insurer refuses to pay for daily monitoring, they are ignoring the fact that without daily moisture readings, there is no proof that the structure is actually drying. If the contractor pulls the equipment too early because the insurer refused to pay for monitoring, and mold grows three weeks later, the insurer will likely deny that mold claim as “maintenance” or “gradual seepage.” This is a trap. You must insist on the full, scientifically backed scope of work from the beginning.

Manufacturer Specifications as Concrete Proof

Beyond the IICRC, manufacturer specifications provide an airtight argument for necessity. For instance, if you have a high-end engineered hardwood floor that has been saturated, the manufacturer’s warranty likely dictates exactly how that material must be handled. If the manufacturer says the floor cannot be sanded and must be replaced if moisture levels exceed a certain percentage, then replacement is “necessary.”

The insurer may try to suggest a “reasonable” repair (like a patch), but if that repair voids your manufacturer’s warranty, it is not a “reasonable” solution. It leaves you in a worse position than you were before the loss. Using manufacturer technical data sheets is one of the most powerful ways to shut down an adjuster’s attempt to cut the scope of work.

Overcoming ‘Not Covered’ and Scope-Cut Objections

Once you have established the technical necessity of the work, the insurer may pivot to their second line of defense: “This isn’t covered under your policy.” This often manifests as an objection to code upgrades or the “Line of Sight” rule.

Code upgrades are a frequent point of contention. If your 1970s home suffers a kitchen fire, the local building inspector may require that the entire kitchen’s electrical system be brought up to current NEC (National Electrical Code) standards. The insurer will often argue they only owe for what was there—the old, ungrounded wiring. However, most modern policies include “Ordinance or Law” coverage. If you have this coverage, the insurer must pay for the upgrades required by law. The necessity here is legal, not just physical.

To overcome these objections, you should:

• Demand the “Basis of Denial” in Writing: If an adjuster cuts a line item, ask them to cite the specific policy exclusion or the technical standard they are using to justify the cut. Most cannot do this.
• Involve the Professionals: If the adjuster disputes the drying plan, have your IICRC-certified technician speak directly to them. Professional-to-professional conversations often resolve “necessity” issues that a homeowner might struggle to articulate.
• Don’t Accept Arbitrary Limits: Insurers often have internal “caps” on things like “PPE” (Personal Protective Equipment) or “Content Manipulation.” These caps are not in your policy. If it takes four hours to move your furniture to save it from water damage, the insurer owes for four hours, not a flat “two-hour cap.”

The Importance of Documentation

In the “Reasonable and Necessary” battle, the side with the best documentation wins. This means moisture maps, infrared camera photos, atmospheric readings (RH, GPP), and detailed daily logs. If the insurer sees that the contractor has documented the “Dry Standard” and “Dry Goal” for every affected material, it becomes nearly impossible for them to argue that the work was superfluous.

If you are struggling with a claim where the insurer is refusing to pay for the proper scope of work, you are not alone. This is a standard tactic used to protect the carrier’s bottom line. By positioning yourself as an informed policyholder who understands building science and industry standards, you level the playing field. You aren’t just asking for money; you are demanding the fulfillment of a contract based on objective, verifiable data.

Ultimately, your goal is to ensure that your property is returned to a safe, habitable, and structurally sound condition. Anything less is a failure of the insurance promise. Don’t let an adjuster’s “opinion” override the requirements of the law and the standards of the industry.
