Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Frost 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 Frost 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 Frost 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 Frost team is equipped and trained to handle.
Wall cavity drying in Frost is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor and hardwood drying in Frost is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Frost 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 Frost structures.
Large-scale commercial drying in Frost is project-managed from day one with zone-specific reading logs.
Every active structural drying program in Frost 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 Frost 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.
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.



"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 Frost 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."
