Estimating Best Practices

Writing Estimates That Get Approved

Estimating best practices are the professional standards that produce complete, accurate, and defensible Xactimate estimates that maximize legitimate recovery while surviving carrier review. The difference between a contractor who consistently gets full payment and one who constantly supplements is usually not the scope of damage. It is the quality of the initial estimate. A well-written first submission reduces review cycles, speeds up payment, and builds credibility with adjusters.

Best practices are not about gaming the system. They are about documenting real damage thoroughly and translating it into the correct Xactimate line items.

The Foundation: Documentation

Every line item in the estimate should be traceable to a photo, field note, or code requirement. Before writing a single line in Xactimate, organize your inspection documentation. Label photos by location and component. Note the manufacturer, age, and condition of existing materials. Measure or verify pitch, penetrations, and accessory components. This documentation is both the source material for your estimate and the evidence that supports it during review.

Estimate Structure and Completeness

Start with the Sketch to establish accurate measurements. Use the correct price list region. Add line items systematically by working through the scope from removal through installation, including all accessory items like starter strip, drip edge, flashing, ridge cap, and pipe boots. Review the estimate against a standard checklist before submitting. Check that quantities match the Sketch, that the correct material specifications are selected, and that every item is categorized under the right trade group. A complete estimate submitted once beats an incomplete estimate that requires three supplement rounds.
