Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Holden 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 Holden team brings to every structural drying project that ensures complete, documented results.
Undersized or generic dehumidification is the most common technical failure in Holden drying projects.
Every active drying project in Holden 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 Holden 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 Holden 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.
Insurance-formatted drying documentation means faster settlement and fewer adjuster callbacks.
Here are the specific drying scenarios and assembly types our Holden team is equipped and trained to handle.
Wall cavity drying in Holden is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor and hardwood drying in Holden is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Holden 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 Holden structures.
Large-scale commercial drying in Holden is project-managed from day one with zone-specific reading logs.
Mold prevention is not a separate service — it's built into every Holden structural drying program we run.


Before one piece of drying equipment is placed, our Holden 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 Holden 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 Holden 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."
"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 Holden 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."
