Most water damage events look dry long before the structural assemblies actually are. A room that smells fine and feels dry to the touch may have framing at 25-30% moisture content — well above the 6-12% target range required for true structural drying. COS Water Damage Restoration's S Coffeyville structural drying program is driven by daily psychrometric readings, not visual judgment.
The difference between structural drying done right and structural drying done fast is what ends up in your walls three months later.
Low-grain refrigerant (LGR) dehumidifiers operate more efficiently in the low-humidity conditions created by an active drying program than conventional dehumidifiers — achieving lower dewpoint conditions that accelerate evaporation from structural materials. Our S Coffeyville structural drying crews deploy properly sized LGR equipment based on the specific volume and material profile of your affected assemblies. Equipment sizing is calculated, not estimated.
Every active drying project in S Coffeyville 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 S Coffeyville properties originates. It's where we focus.
Insurance-formatted drying documentation means faster settlement and fewer adjuster callbacks.
Here are the specific drying scenarios and assembly types our S Coffeyville team is equipped and trained to handle.
The most common drying failure in S Coffeyville water damage projects is a wall framing cavity left with elevated moisture content after surface materials are dry. Our S Coffeyville team uses calibrated cavity access — typically 1-inch drill holes at the base of the wall framing cavity — to introduce directed airflow from high-velocity air movers into the stud bay, paired with LGR dehumidification to extract the evaporated moisture. Moisture readings at framing sensor points confirm completion. Access ports are patched and filled after the program completes, typically leaving no visible trace of the access procedure.
Subfloor and hardwood drying in S Coffeyville is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in S Coffeyville often goes undetected — we include it in every below-grade moisture mapping session.
Ceiling assembly drying is one of the more technically demanding aspects of water damage restoration in S Coffeyville structures.
Large-scale commercial drying in S Coffeyville is project-managed from day one with zone-specific reading logs.
Every active structural drying program in S Coffeyville is also a mold prevention program — because the conditions that support mold growth (elevated moisture content in organic materials and elevated relative humidity in the air space) are exactly the conditions a drying program is designed to eliminate. Our daily reading sessions include assessment of the ambient RH and temperature conditions in each drying zone against the threshold conditions that support mold colonization. If readings suggest an elevated mold risk — particularly in projects where extraction was delayed — we address it proactively with targeted antimicrobial treatment during the active drying program.


Before one piece of drying equipment is placed, our S Coffeyville team completes a full moisture mapping session using FLIR thermal imaging and calibrated pin-type and non-penetrating meters. The map documents all affected assemblies, saturation levels, and the extent of moisture migration through the structure. Equipment placement and sizing are calculated from this map.
Based on the moisture map, our S Coffeyville 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.
Every calendar day, our S Coffeyville technician visits your property, takes complete psychrometric readings at all sensor points and ambient measurement locations, logs the data, adjusts equipment if indicated, and reports the daily progress to you and your insurance carrier. The drying program continues until all assemblies reach their EMC target range.
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."
"Our insurance adjuster was skeptical about the drying scope initially, but COS Water Damage Restoration's documentation — the daily moisture logs, the floor plan with sensor point locations, the before and after readings — was thorough enough that the adjuster approved the full scope without any back-and-forth. That documentation is worth its weight in the claim settlement alone."
"We had a particularly complex drying project across three floors of a S Coffeyville 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."
