7 Water Damage Line Items Adjusters Always Deny (And the IICRC Citations That Override Them)

The Water Damage Supplement Pattern

Water damage claims follow a predictable pattern: the adjuster's Xactimate estimate comes in, and the same line items are missing every time. Antimicrobial treatment. Equipment monitoring. Content manipulation. Additional drying days. It's not random — adjusters are trained to exclude these items because most restoration contractors don't know how to fight back.

Here are the 7 water damage line items that adjusters routinely deny, along with the exact IICRC S500 citations and Xactimate codes that get each one approved.

1. Antimicrobial Treatment (WTR ANTIM)

Antimicrobial treatment is required on all Category 2 and Category 3 water losses per IICRC S500 Section 12.3.2. Adjusters frequently deny it on Category 2 losses, claiming it's "not necessary." Cite IICRC S500 Section 12.3.2 directly — it mandates antimicrobial application on all Category 2 losses involving porous materials.

2. Content Manipulation (CONT MANIP)

Moving, protecting, and replacing contents during a water damage restoration is a legitimate labor item. Adjusters frequently exclude it or include a nominal amount that doesn't reflect actual time. Document the specific items moved, the time required, and the reason they needed to be moved (access to affected areas). Cite IICRC S500 Section 9.1, which requires removal of contents to access affected structural materials.

3. Equipment Monitoring (WTR EQPMNTMON)

Daily equipment monitoring — checking moisture readings, adjusting equipment placement, and documenting drying progress — is required per IICRC S500 Section 13.4. Adjusters frequently exclude monitoring time or include only a fraction of the actual time required. Document each monitoring visit with moisture readings, equipment settings, and time spent.

4. Additional Drying Days

When a structure doesn't reach drying goals within the initial estimate period, additional drying days are required. Adjusters frequently deny additional days without reviewing the moisture documentation. Provide daily moisture reading logs showing that the structure had not reached IICRC S500 drying goals (typically below 16% moisture content for wood) when the additional days were needed.

5. HEPA Vacuuming

HEPA vacuuming is required on all Category 3 losses and on any loss involving mold per IICRC S500 Section 12.4 and IICRC S520. Adjusters frequently exclude it or include standard vacuuming rates instead of HEPA rates. Document the category of loss and cite the applicable IICRC standard.

6. Overhead & Profit (O&P)

O&P at 10% overhead + 10% profit is standard on all restoration claims. Adjusters deny it on the grounds that restoration contractors are "direct" contractors. Cite Xactimate's own documentation supporting O&P and the Restoration Industry Association (RIA) position statement on O&P for restoration contractors.

7. Dehumidifier Rental (WTR DEHUMID)

Dehumidifier rental is billed per day per unit. Adjusters frequently include fewer units than were deployed or fewer days than were required. Document each unit deployed with serial numbers, placement locations, and daily readings. The IICRC S500 psychrometric calculations for your specific job (temperature, humidity, affected square footage) determine the required number of units — include these calculations in your supplement.
