What Goes on a Water Mitigation Invoice: Line Items, Documentation, and What Gets Cut
The WTR line items that belong on a water mitigation invoice in the order the work happened, the documentation package a carrier requires to pay it, and the four things third-party auditors flag most often.
A water mitigation invoice submitted to an insurance carrier is an Xactimate estimate for the emergency phase of the loss, priced on the regional price list in effect on the date of loss and submitted with the documentation that proves every line. The free water damage invoice templates that dominate search results get returned or reduced because carriers pay against IICRC S500-validated line items rather than a list of services with a total at the bottom. Every quantity has to trace back to something recorded on site.
Estimate first, invoice second
The mitigation invoice and the mitigation estimate are the same document at two points in time. The estimate goes out with projected equipment days. The invoice goes out after equipment comes off the job, with actual days, hours, and quantities substituted in. Contractors who build the invoice from scratch at the end of the job, off a blank template instead of the estimate they already wrote, lose the line items they scoped on day one.
Submitting an invoice with no supporting scope is the most common structural failure. The sketch, the moisture data, and the equipment log are what turn a dollar figure into a file an adjuster can approve.
The line items, in the order the work happened
Unit prices below are published examples. Actual prices vary by price list, region, and version, and the list on the estimate has to match the property zip and the date of loss.
Emergency service call
Two codes cover the trip itself. WTR ESRVD is the emergency service call during business hours, and WTR ESERV is the after hours version covering evenings and weekends. Both carry the administrative cost of mobilizing an emergency crew and exclude all labor, material, and equipment used to do the work, which is a frequent source of confusion when an invoice comes back short.
Extraction
WTR EXT covers extraction with a carpet wand, published around $0.53 per square foot. WTR EXTW covers weighted extraction with a water claw or comparable tool, published around $0.92 per square foot, and applies whenever the crew used a weighted head. Extraction carries variants for hard surface, Category 2 and 3 water, and after hours. Appending A prices the additional labor burden of an after hours call, which the service call code by itself does not cover.
Demolition and removal
WTR DRYW removes and bags wet drywall by the square foot, published around $0.86 per square foot. WTR DRYWLF prices a two foot flood cut by the linear foot, and WTR DRYWLS is the Category 3 drywall removal. WTR FC removes flooring with a suffix for the material: C for carpet, T for tile, V for vinyl, W for wood. WTR TRI removes trim, WTR BASE removes baseboard, and WTR INS removes insulation including bagging, with a confined space option.
Antimicrobial
WTR GRM applies germicide, published around $0.22 per square foot, with BIO for spore-based product, B for botanical, and A for after hours.
Equipment, by the day
WTR DRY prices air movers per day, with a plus variant for axial units. WTR DHM prices dehumidifiers per day and requires accurate cubic footage in the sketch to support the sizing. WTR NAFAN prices the air filtration device, published around $71.54 per day. Each of these has to be matched by a dated equipment log entry.
Equipment labor, by the hour
WTR EQ is equipment labor in hours: travel, setup, daily on-site monitoring, and teardown. The per-day equipment codes carry zero labor. Leaving WTR EQ off means the crew's daily monitoring visits were performed and never billed, and it is the single most commonly omitted line on a mitigation invoice.
Protection and containment
WTR MASKFL masks flooring with adhesive-backed plastic, around $0.41 per square foot. WTR PROT covers and protects with painter's plastic, around $0.29 per square foot. WTR BLK blocks and pads furniture, around $42.60 per room.
The documentation package that rides with the invoice
Carriers ask for the same set on nearly every water file:
- Daily psychrometric readings. Temperature, relative humidity, dew point, and grains per pound from the affected area, an unaffected reference area, the dehumidifier outlet, and outside.
- Moisture content readings at numbered monitoring points, showing progression toward the dry standard.
- Equipment placement records with counts, placement dates, removal dates, and serial numbers.
- A sketch with room dimensions, which also drives the square footage on every extraction and demolition line.
- Photographs of the affected areas, the equipment in place, and the materials removed.
- A signed work authorization and, where the carrier requires one, a certificate of completion.
Xactimate carries a mitigation log for this. It sits in Sketch, under XactScope, on the Mitigation Log tab next to the Guide tab, and becomes available once zones and affected areas are created and equipment is placed in the sketch. It records air movers and air scrubbers with operating hours, climate readings with derived GPP, dehumidifiers with pints extracted, and saturation readings by material and location, organized by day.
Who reviews the invoice before it gets paid
Mitigation invoices frequently route to a third-party audit before the carrier issues payment. SecondLook, the emergency mitigation invoice audit program run by Wardlaw Claims Service, has run individualized file audits against IICRC and S500 standards since 2013 and reports over $200 million in IICRC-validated indemnity reductions. The auditor checks whether the work billed is supported by the standard and by the file.
Four things get flagged consistently:
- Equipment days with no matching psychrometric progression. Days billed after the readings flatten out are the first cut.
- Overlapping or duplicate charges on the same day, including a detach line billed alongside a code that already contains it.
- A price list that does not match the property zip or the date of loss.
- Quantities that do not tie to the sketch, most often flood cut linear feet entered as square feet.
Frequently Asked Questions
Is a water mitigation invoice the same as an Xactimate estimate?
They are the same document at different stages. The estimate carries projected equipment days. The invoice carries actual days, hours, and quantities after the equipment is pulled, on the same price list and sketch.
Can a generic water damage invoice template be submitted to an insurance carrier?
A generic template will be returned or reduced on most claims. Carriers evaluate mitigation charges against Xactimate line items on a regional price list and against IICRC S500, and a lump sum for "drying and dehumidification" gives the adjuster nothing to validate.
What is the most commonly missed line item on a water mitigation invoice?
Equipment labor, WTR EQ, billed in hours. The per-day equipment codes contain no labor, so travel, setup, daily monitoring visits, and teardown go unbilled unless that line is added.
Does the emergency service call code cover the crew's labor on site?
No. Both codes cover the administrative cost of mobilizing the crew and exclude all labor, material, and equipment used to perform the work. After hours labor burden is captured by appending the A variant to the work codes themselves.
