Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Tokeland drying crew completes the program when the readings say it's done — not before.
Structural Drying is a science-driven process built on thermodynamics, psychrometrics, and equipment calibration — not fans pointed at a wet floor and checked weekly. Here's what our Tokeland team brings to every structural drying project that ensures complete, documented results.
Undersized or generic dehumidification is the most common technical failure in Tokeland drying projects.
Every active drying project in Tokeland 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.
The wall framing cavity is where water damage most often leads to long-term problems in Tokeland properties. After water events, wall cavities absorb moisture through both the drywall face and the framing itself — and standard floor-level drying equipment does not reach these cavities. Our Tokeland crew drills calibrated access ports at the base of affected wall sections and inserts directional air nozzles that force conditioned airflow through the cavity space, pairing it with LGR dehumidification to achieve complete cavity drying alongside floor-level assemblies.
COS Water Damage Restoration's Tokeland 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 Tokeland team is equipped and trained to handle.
Wall cavity drying in Tokeland is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor and hardwood drying in Tokeland is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Tokeland 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 Tokeland property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Tokeland 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 Tokeland is project-managed from day one with zone-specific reading logs.
Mold prevention is not a separate service — it's built into every Tokeland structural drying program we run.


Equipment before mapping is guesswork. Mapping before equipment is science.
Based on the moisture map, our Tokeland 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.
When all sensor point readings fall within the target equilibrium moisture content range for the specific materials being dried, we perform a final comprehensive moisture survey of the entire affected area and issue a written drying completion report. This report is included in your insurance claim documentation and serves as your record of successful structural drying.



"The most important thing about COS Water Damage Restoration's Tokeland structural drying was that they explained the readings to me every single day. I understood what the numbers meant, what the target was, and how far we were from completion. By day six I was watching the moisture content readings in our wall framing drop from 28% to 11% and understood exactly what was happening and why. That level of transparency is what you need when your home is full of drying equipment for a week."
"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 Tokeland 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."
