How to Estimate Hardwood Floor Drying in Xactimate
The Xactimate codes for hardwood floor drying (WTR WFI, WFDAD), when to dry in place versus tear out, the IICRC S500 moisture targets that set the drying goal, and the documentation that keeps mat days from getting cut.
Hardwood floor drying is estimated in Xactimate under the WTR category using the WFI subcode, which covers a wood floor drying extraction mat system billed per 24 hour period. When the affected floor runs more than 400 square feet, the WFDAD add-on kit subcode goes on top of it. Everything else follows from there: mat days, the dehumidification and air mover days running alongside them, monitoring labor, and the moisture documentation proving the drying goal was reached.
Decide whether the floor is restorable before writing anything
The most expensive mistake on a wood floor loss is scoping in-place drying on a floor that was never going to make it, or tearing out a floor that would have dried.
Cupping measured under 3/16 inch across a 6 foot span is generally treated as restorable with in-place drying. Once cupping exceeds that, or the boards show buckling or face-checking, the floor moves toward replacement. Measure it with a straightedge and photograph the gap.
The subfloor is a separate call. Plywood tolerates higher moisture content and dries faster than oriented strand board, which absorbs water quickly and frequently needs replacement once saturated. Subfloor panels reading above 19 percent moisture content require active drying, and panels showing edge swell, surface delamination, or structural movement are replacement candidates regardless of how the finish floor reads.
Document that decision in the file on day one. Adjusters challenge the mat system far more often when the estimate never explains why in-place drying was the right call.
The line items
WTR WFI, wood floor drying extraction mat
The price list description reads "Wood floor drying extraction mat (per 24 hr prd) No monit." Two details in that description control how it gets billed.
- The unit is a 24 hour period, so quantity equals the number of drying days, not the square footage of the floor.
- "No monit" means daily monitoring labor is not included in the line. That labor bills separately.
Published Xactimate pricing guides put hardwood floor drying between $3.00 and $10.00 per square foot for the total drying scope. The mat system rate varies by region and Xactware updates the price list monthly, so pull the current figure for that market rather than carrying a number over from a prior job.
WFDAD, wood floor drying add-on kit
Add the WFDAD subcode when the drying area exceeds 400 square feet. Below that threshold it does not belong on the estimate, and putting it there on a 250 square foot kitchen is an easy cut for a reviewer.
The equipment running alongside it
A mat system does not dry a floor alone. The moisture pulled from the wood has to go somewhere, so standard mitigation equipment stays on the estimate for the same duration:
- WTRDHM, dehumidifier, per day. Size it off the cubic footage of the affected space, not the square footage of the floor.
- WTRDRY, air mover, per day. Choose the axial option when that is what was actually deployed.
- WTRNAFAN, air filtration device, per day. Published pricing runs around $71.54 per day, which totals $286.16 over a four day cycle.
- WTREQ, monitoring labor, hourly. This covers travel to the project, equipment setup, and taking atmospheric and moisture readings on site each day. Because WTR WFI carries the "No monit" designation, WTREQ is the only place that time gets captured.
If the floor comes out anyway
When cupping or subfloor damage pushes the job to replacement, the scope shifts to WTRFC tear-out quantities for the flooring, plus disposal, and the mat system drops off entirely. Mixing both approaches on the same continuous run of flooring is a fast way to draw a revision request.
Set the drying goal against a real reference
The IICRC S500 defines the dry standard as a reasonable approximation of the moisture content of a material before the water intrusion, and the drying goal as the target moisture content the restorer establishes for the end of the drying process. Neither is a number pulled from a table.
Hardwood flooring targets 6 to 9 percent moisture content in most United States climate zones. The way to establish the specific target for a given structure is to take readings in unaffected wood of the same species in the same building and treat those as the baseline. The drying goal then sits within roughly 2 to 4 percentage points of that unaffected reference.
Hardwood also puts most of these losses into Class 4 under the S500, covering wet materials with very low permeance and porosity. Class 4 drying takes longer and often requires specialty methods. Saying so explicitly in the file is what justifies a mat day count running past the three day cycle an adjuster expects on carpet and pad.
What keeps the mat days from getting cut
Every day of WTR WFI billed needs a corresponding entry in the drying log. The entries that hold up include:
- Numbered monitoring points, kept in the same positions for the full duration
- A daily moisture content reading at each point on the finish floor and, where accessible, the subfloor
- The unaffected reference readings that establish the dry standard
- Daily temperature and relative humidity readings inside the containment and outside
- Photos of the mat layout and panel placement on the day of installation
- The cupping measurement taken at initial inspection
Reductions in review usually trace to something mechanical: mat days billed past the date readings show the floor hit its goal, WFDAD applied to a floor under 400 square feet, monitoring hours duplicating labor already in another line, or no photo showing the mat system deployed.
Frequently Asked Questions
What Xactimate code is used for hardwood floor drying?
Wood floor drying uses the WTR selector with the WFI subcode, described in the price list as a wood floor drying extraction mat billed per 24 hour period. For drying areas over 400 square feet, the WFDAD add-on kit subcode is added.
Does the wood floor drying line item include monitoring labor?
No. The WTR WFI description ends in "No monit," which means daily monitoring is excluded. That time bills separately under WTREQ, covering travel, setup, and daily readings.
When should hardwood be replaced instead of dried in place?
Cupping under 3/16 inch across a 6 foot span is generally restorable through in-place drying. Cupping beyond that, buckling, or face-checking points toward replacement, as does a subfloor with edge swell, delamination, or readings that will not come down with active drying.
What moisture content should hardwood be dried to?
Most United States climate zones put the target between 6 and 9 percent. The defensible number for a specific job comes from reading unaffected wood of the same species elsewhere in the building and drying to within 2 to 4 percentage points of that baseline.
