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 Alledonia structural drying program is driven by daily psychrometric readings, not visual judgment.
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 Alledonia team brings to every structural drying project that ensures complete, documented results.
Undersized or generic dehumidification is the most common technical failure in Alledonia drying projects.
Documented daily readings are what separate a professional drying program from a rental dehumidifier in the corner.
Wall cavity drying is where most post-loss mold in Alledonia 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 Alledonia team is equipped and trained to handle.
The most common drying failure in Alledonia water damage projects is a wall framing cavity left with elevated moisture content after surface materials are dry. Our Alledonia 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 Alledonia is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Alledonia 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 Alledonia property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Alledonia 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 water events in Alledonia commercial or multi-family properties may affect dozens of rooms across multiple floors — requiring coordinated equipment staging, airflow balancing between spaces, and readings management across a large number of sensor points simultaneously. Our Alledonia commercial drying team uses scaled equipment deployment and a project management approach that tracks readings and equipment across the full property footprint, adjusting equipment placement and settings daily based on the reading data from each zone.
Mold prevention is not a separate service — it's built into every Alledonia structural drying program we run.


Before one piece of drying equipment is placed, our Alledonia 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.
Equipment placement is engineered based on the moisture map and assembly data — not placed by habit.
Every calendar day, our Alledonia 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.



"The most important thing about COS Water Damage Restoration's Alledonia 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 Alledonia 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."
