Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Washburn drying crew completes the program when the readings say it's done — not before.
The difference between structural drying done right and structural drying done fast is what ends up in your walls three months later.
Undersized or generic dehumidification is the most common technical failure in Washburn drying projects.
Every active drying project in Washburn receives a daily psychrometric reading session: temperature, relative humidity, specific humidity, grains per pound of moisture in the air, and moisture content readings at fixed sensor points in each structural assembly. These readings are logged and provided as documentation of the drying program for your insurance claim. Drying is declared complete only when readings at all sensor points fall within the target EMC range for the material species being dried.
Wall cavity drying is where most post-loss mold in Washburn properties originates. It's where we focus.
COS Water Damage Restoration's Washburn drying technicians generate moisture logs formatted specifically for insurance claim submission — daily readings at sensor point locations mapped to a floor plan, equipment placement and settings recorded, and final confirmation readings that document the completion of the drying program. Xactimate-compatible line items for each day's equipment and labor make the drying scope transparent to your adjuster and minimize the chance of a supplement dispute on the drying phase of your claim.
Here are the specific drying scenarios and assembly types our Washburn team is equipped and trained to handle.
Wall cavity drying in Washburn is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor assemblies — OSB or plywood sheathing over floor joists — and hardwood flooring systems require targeted drying approaches because of their density and their tendency to cup, buckle, or swell when dried too aggressively or left wet too long. Our Washburn drying crew evaluates hardwood flooring species and moisture content before recommending drying-in-place versus removal, and when drying in place is appropriate, we use floor drying mats that direct conditioned air against the top face of the hardwood under controlled pressure — accelerating evaporation while minimizing the differential drying stress that causes cupping.
Crawlspace saturation after a water event in Washburn often goes undetected — we include it in every below-grade moisture mapping session.
Water that migrates down from an upper floor or a roof intrusion in a Washburn property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Washburn team installs ceiling injection ports and directs positive-pressure airflow through ceiling cavities, combined with LGR dehumidification of the affected room air space. Ceiling drywall that cannot be dried to target moisture content is removed — rather than left to become a mold substrate — and documented in the scope for replacement.
Large-scale commercial drying in Washburn is project-managed from day one with zone-specific reading logs.
Mold prevention is not a separate service — it's built into every Washburn structural drying program we run.


Equipment before mapping is guesswork. Mapping before equipment is science.
Based on the moisture map, our Washburn drying specialist designs an equipment layout: the number and type of LGR dehumidifiers required for the affected volume, the positioning and orientation of high-velocity air movers to create optimal airflow patterns across saturated assemblies, and the placement of cavity access ports for wall or ceiling injection drying.
Daily readings, daily reporting, daily equipment adjustment if needed — documented throughout.
Completion is confirmed by instruments and documented in writing. No visual estimates.



"We'd had a water damage company dry our house after a previous event and they removed equipment on day 5 and called it done. Three months later, mold behind the walls. This time I specifically chose COS Water Damage Restoration because of their documentation process. Daily readings, specific sensor point data, instrument-confirmed completion. No mold, no callbacks, no repeat of the last time."
"The thermal imaging session at the beginning was what showed us the water had migrated into a wall cavity adjacent to the flooded room that we never would have found otherwise. COS Water Damage Restoration set up wall cavity drying for that section specifically, and the final readings confirmed it came out completely dry alongside everything else. That's the kind of detail that prevents the mold problem three months later."
"We had a particularly complex drying project across three floors of a Washburn office building after an upstairs pipe event. COS Water Damage Restoration managed the zone readings, adjusted equipment as the drying progressed on different floors at different rates, and wrapped the entire building within 11 days with full documentation. That's professional-grade project management."
