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 Carrollton 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 Carrollton team brings to every structural drying project that ensures complete, documented results.
Undersized or generic dehumidification is the most common technical failure in Carrollton drying projects.
Every active drying project in Carrollton 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 Carrollton properties originates. It's where we focus.
Insurance-formatted drying documentation means faster settlement and fewer adjuster callbacks.
COS Water Damage Restoration's Carrollton structural drying service covers every assembly type and situation encountered in a water damage event — from standard floor and wall assemblies to hardwood systems, crawlspace framing, and multi-story moisture migration events.
The most common drying failure in Carrollton water damage projects is a wall framing cavity left with elevated moisture content after surface materials are dry. Our Carrollton 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 assemblies — OSB or plywood sheathing over floor joists — and hardwood flooring systems require targeted drying approaches because of their density and their tendency to cup, buckle, or swell when dried too aggressively or left wet too long. Our Carrollton drying crew evaluates hardwood flooring species and moisture content before recommending drying-in-place versus removal, and when drying in place is appropriate, we use floor drying mats that direct conditioned air against the top face of the hardwood under controlled pressure — accelerating evaporation while minimizing the differential drying stress that causes cupping.
Crawlspace drying in Carrollton properties is complicated by limited access, typically poor natural ventilation, and the presence of vapor barriers that may trap moisture against wood framing. Our Carrollton below-grade drying team is equipped with compact high-velocity air movers that fit through standard crawlspace access hatches, portable LGR units configured for below-grade operation, and moisture meters suitable for sub-surface readings at joist and beam locations. Vapor barrier condition is evaluated and re-secured after drying if disturbed during the process.
Ceiling assembly drying is one of the more technically demanding aspects of water damage restoration in Carrollton structures.
Large water events in Carrollton 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 Carrollton 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 Carrollton structural drying program we run.


Equipment before mapping is guesswork. Mapping before equipment is science.
Based on the moisture map, our Carrollton 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 Carrollton 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 manage several Carrollton commercial properties and structural drying after water events is something we deal with periodically. COS Water Damage Restoration is the only company we use because of their documentation process. Zone-specific readings, daily logs we can review from our office, and a written drying completion report at the end of every project. When a tenant asks for proof that remediation was complete, we have an instrument-confirmed document, not a technician's verbal assurance."
