Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Polk 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 Polk team brings to every structural drying project that ensures complete, documented results.
Undersized or generic dehumidification is the most common technical failure in Polk drying projects.
Every active drying project in Polk 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 Polk 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 Polk team is equipped and trained to handle.
Wall cavity drying in Polk is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor and hardwood drying in Polk is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Polk 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 Polk property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Polk 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 Polk 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 Polk 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.
Every active structural drying program in Polk 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.


Equipment before mapping is guesswork. Mapping before equipment is science.
Equipment placement is engineered based on the moisture map and assembly data — not placed by habit.
Every calendar day, our Polk 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.
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 Polk 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."
