Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Piedmont 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 Piedmont drying projects.
Documented daily readings are what separate a professional drying program from a rental dehumidifier in the corner.
The wall framing cavity is where water damage most often leads to long-term problems in Piedmont 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 Piedmont 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.
COS Water Damage Restoration's Piedmont drying technicians generate moisture logs formatted specifically for insurance claim submission — daily readings at sensor point locations mapped to a floor plan, equipment placement and settings recorded, and final confirmation readings that document the completion of the drying program. Xactimate-compatible line items for each day's equipment and labor make the drying scope transparent to your adjuster and minimize the chance of a supplement dispute on the drying phase of your claim.
Here are the specific drying scenarios and assembly types our Piedmont team is equipped and trained to handle.
The most common drying failure in Piedmont water damage projects is a wall framing cavity left with elevated moisture content after surface materials are dry. Our Piedmont 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 Piedmont is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Piedmont 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 Piedmont structures.
Large water events in Piedmont 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 Piedmont 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 Piedmont structural drying program we run.


Equipment before mapping is guesswork. Mapping before equipment is science.
Based on the moisture map, our Piedmont 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 Piedmont 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."
"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 Piedmont 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."
