Alright, Working with Adjusters: Line-Item Estimating, Scope Agreement & Supplements. Don't let the plain title fool you. Here's the part that actually matters on the job: An insurance estimate is a line-item argument built from a measured sketch, and every line needs a photo, a reading, or a note that an adjuster can approve without calling you. Learn it well and your estimates get approved in days instead of weeks, and the supplements you write get paid.

The intro course explained the life of a claim. This lesson is the working method of writing the estimate in the format the industry uses, agreeing scope with the adjuster, and handling the money and paperwork that follow. The format is common across the major estimating platforms, so no product is named here.

Who you are dealing with

• Staff adjusters work for the carrier; independent adjusters are contracted by it, often during storms; desk adjusters handle smaller claims from photos and your file; field adjusters inspect in person; large-loss or general adjusters handle big or complex claims.
• Third-party administrators (TPAs) manage claims for carriers and audit your estimates against program rules.
• Public adjusters represent the owner and are licensed. You are not one. Talk scope and price; leave coverage and policy interpretation to the carrier and the owner.
• Consultants such as hygienists, engineers, and estimate reviewers appear on larger losses and read your file line by line.

The sketch comes first

Every room in the estimate is measured: length, width, ceiling height, and the openings (doors, windows, missing walls) that subtract from wall area. The sketch is drawn in the software, which calculates the floor, wall, ceiling, and perimeter quantities that every line item pulls from. Measure the whole room even when only part is damaged, note which walls are affected, and photograph the tape on the long dimensions. An adjuster who re-measures and finds a different wall area stops trusting every other number in the file.

Anatomy of a line item

Each line has a category and selector code that identifies the trade and the task, a description, a quantity, a unit (SF, LF, SY, EA, HR, DAY, or a minimum charge), and a unit price that bundles labor, material, and equipment for the region and the month. The software prices from a regional database updated periodically; carriers mostly argue line items and quantities, not unit prices, so the leverage is in the scope. Typical mitigation lines on a water loss include water extraction per square foot, carpet pad removal, flood-cut drywall removal per square foot or linear foot, baseboard detach, cabinet toe-kick detach for drying, antimicrobial application per square foot, air movers and dehumidifiers per unit per day (dehumidifiers by size class), air filtration devices per day, moisture monitoring and equipment setup per hour, PPE, containment and negative air per linear foot or square foot, debris hauling by the load, contents manipulation per hour, and an after-hours emergency service charge. Fire and mold losses add cleaning per square foot by method, sealing, duct cleaning, deodorization by method, and contents inventory, pack-out, cleaning, and storage lines. The rebuild estimate is a separate document with the trades in order.

Making every line defensible

• A photo for every removal and every piece of equipment placed, labeled by room.
• A reading for every drying line: the daily log justifies the equipment count and the number of days.
• A note for every judgment call: why the drywall came out instead of drying in place, why the cabinets were detached, why the ceiling tile was replaced.
• Quantities tied to the sketch: if the flood cut was 2 feet on three walls, the line shows that math.
• Minimums and after-hours applied once and explained. Then send the estimate with the sketch, the photo report, the drying report, and the signed work authorization as one package.

Scope agreement and overhead and profit

On anything beyond a small loss, ask for a joint inspection and walk the building with the adjuster. Agree on what is damaged and what the repair is before anyone prices it; a scope argument settled on site rarely comes back. When a general contractor coordinates multiple trades on the rebuild, overhead and profit is commonly added as a percentage on top of the line items; practice and percentages vary by carrier and region, and it is justified by the coordination you actually provide. Keep the mitigation and rebuild estimates separate; mitigation is often approved and paid first.

Supplements, depreciation, and the money

• Supplements cover damage found after the estimate was approved. The rule is stop, photograph, measure, write the supplement, and get it approved before the extra work, except for work needed to prevent further damage, which you document as you go. A supplement sent after the work is done is a request for a favor.
• Replacement cost versus actual cash value. Many policies pay the actual cash value first (replacement cost minus depreciation) and release the recoverable depreciation when the work is complete and you submit the final invoice and a certificate of completion. Non-recoverable depreciation is never paid; the owner covers that gap.
• Deductible. The owner owes it, and waiving it or hiding it in the estimate is insurance fraud in many states.
• Ordinance or law coverage pays for code upgrades the repair triggers; those get their own line items with the code reference.
• Matching rules for flooring and siding continuity vary by state and policy; present the facts and let the carrier apply the policy.
• Checks often name the owner and the mortgage lender; plan your cash flow around the endorsement time.

Going Deeper (Intermediate)

Program and TPA work comes with rules written into the estimate: equipment caps per square foot, maximum drying days without justification, required photo counts, and turnaround times. Read them before the first job, because the audit will. On direct work, the owner is your customer and the carrier is the payer, and the two need different communication: the owner gets plain-language updates and what the deductible means; the carrier gets the file. Keep a log of every adjuster conversation with date, name, and what was agreed, and confirm agreements by email the same day.

Advanced / Pro-Level

Pros write the narrative, not just the lines. A short cover note that states the loss, the category and class, the decisions and why, and what remains unknown gets an estimate approved faster than a perfect line list with no story. They scope the rebuild from the mitigation file, so the drywall quantity in the rebuild matches the removal quantity in the mitigation estimate. They know that line-item disputes are won with standards: a flood cut justified by S500, containment justified by S520, a non-restorable item justified by a documented cleaning attempt. And they track estimate approval time, supplement approval rate, and days to payment by carrier, because those numbers decide which program work is worth keeping.

Practice Challenge

During the rebuild of a water-damaged bathroom, the crew removes the vanity and finds the subfloor rotted and the wall plate soft, neither in the approved estimate. The homeowner is standing there asking you to just fix it. What do you do? (Answer: stop at that spot, photograph and measure the rot and take moisture readings, write a supplement with the added removal, any drying, and the replacement lines tied to the sketch, send it to the adjuster the same day with the photos, tell the owner the carrier approves scope and you will keep the rest of the job moving, and do only the work needed to prevent further damage until the supplement is approved.)

In Practice

An estimator whose package has a measured sketch, labeled photos, a drying report, and a note on every judgment call gets approvals from desk adjusters who never visit. An estimator who sends a line list with no photos spends the week on the phone defending it and loses lines that were legitimate.

Common Mistakes to Avoid

• Estimating before the rooms are measured and sketched
• Equipment and days on the estimate that the daily log does not support
• Doing supplement work before it is documented and approved
• Waiving deductibles or padding lines to cover them
• Negotiating coverage with the carrier on the owner's behalf

Takeaway: An insurance estimate is a line-item argument built from a measured sketch, and every line needs a photo, a reading, or a note that an adjuster can approve without calling you.
