How to document a water mitigation Xactimate estimate
By the Log Cabin team
A water mitigation Xactimate estimate is usually reviewed by someone who never saw the job. They weren't there when the crew pulled baseboard in the middle of the night, and they didn't see the wet cavity behind the vanity. All they have is the file. If the file doesn't show why a line is there, expect questions.
The good news: most of what supports a mitigation estimate is already being collected on the job. It just has to be captured consistently and handed over in a form an estimator can write from. Here's what we look for when a mitigation file comes in.
Start with the moisture map, not the invoice
The scope of a water mitigation estimate comes from where the water went. That means initial moisture readings, taken and recorded before anything is removed, room by room.
A useful moisture map shows:
- Which rooms and which walls were affected, including the rooms next door
- Readings on the affected materials and a dry reference reading for each material type
- Where the readings stopped being wet, so the edge of the affected area is clear
When the readings show a wall was wet partway up, a flood cut just above that line makes sense on paper. When the readings are missing, the same line is just an opinion.
Photos that match the estimate, room by room
Photos are the primary evidence for every line. A mitigation estimate built from the crew's invoice alone tends to miss things the photos show and include things they don't.
Before you send the file, check that you have:
- Overview shots of every affected room before demo starts
- Moisture meter photos with the reading visible and the location identifiable
- Tear-out photos showing what was removed: flood cut height, ceiling openings, insulation, flooring, baseboard, cabinets and toe kicks
- Detach photos for anything that was pulled and set aside, like vanities, toilets and appliances
- Hallways and walk paths, especially where floor protection was laid or containment was built
- Adjacent rooms, even when the answer is that they were checked and are dry
Label photos by room. An estimator matching a pile of unlabeled photos to a sketch is slower, and slower means more chances to miss something.
Drying logs that show the job, day by day
The drying log is what supports the day-based lines on a water mitigation estimate: equipment days, monitoring visits and the drying timeline. Reviewers commonly ask for it, so it's worth getting right before the file goes out.
A drying log that holds up shows:
- Date and time of each visit
- Readings on the same monitoring points each day, so the trend toward dry is visible
- Atmospheric readings (temperature and relative humidity) inside the affected area, outside it and at the equipment
- Equipment in place each day, by type and count, by room
- When equipment was added, moved or picked up, and why
- The final readings that show materials reached the drying goal
The IICRC S500 is the industry standard for water damage restoration, and documenting the job against it is the clearest way to explain why the drying took the time and equipment it did. If a piece of equipment stayed longer than expected, the log should say why: a wall cavity that was slow to come down, a material that needed more time, access issues. A note written on the day carries more weight than an explanation written weeks later.
Equipment placement and pickup records
Equipment lines are easy to question and easy to support. The record should tie each piece of equipment to a room and a date range. A placement diagram or photo of the setup in each room helps, and so does a pickup record that matches the log.
If the equipment count changes partway through the job, make sure the log, the photos and the invoice all tell the same story. Mismatches between those three give a reviewer a reason to slow the file down.
Don't forget the job-level items
Some mitigation lines aren't tied to one room, and they get missed because nobody photographs them. Look at whether the file supports:
- Emergency service call timing. The work authorization or flood report should show when the crew arrived.
- Temporary power. If the crew ran equipment off a generator or a power distribution box, document why.
- Containment. Photos of the barrier, the zipper doors and the negative air setup, with the reason it was needed.
- Floor protection along the paths the crew used.
- Antimicrobial application and HEPA vacuuming on the surfaces that were treated.
- Supervision and monitoring time, supported by the visit records in the drying log.
Each of these needs something in the file that shows it happened. "We always do that" doesn't help a reviewer who wasn't there.
Write it so the reviewer can follow it
Once the documentation is in hand, the estimate itself should make it easy to check:
- Room-by-room structure that matches the sketch, in a consistent order: ceilings, walls, cabinets, counters, floors, drying equipment, containment, general items
- Quantities taken from the sketch and the photos, not rounded guesses. A partial ceiling opening is billed as the opening, not the whole ceiling.
- Line notes on anything unusual: why a material was removed, why containment was built, why equipment ran longer than the standard drying time
- Matching numbers across documents: the estimate, the drying log and the equipment records should agree
A quick pre-send checklist
- Initial moisture map with readings for every affected room
- Labeled photos for every room, including tear-out and detach shots
- Daily drying log with readings, atmospherics and equipment counts
- Equipment placement and pickup records that match the log
- Work authorization showing arrival time
- Sketch in ESX format, or Encircle access for import
- Notes on anything that isn't obvious from the photos
If the file has all of that, a mitigation estimate can be written line by line from the evidence, and every line has something behind it.
