Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Loretto 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 Loretto team brings to every structural drying project that ensures complete, documented results.
Undersized or generic dehumidification is the most common technical failure in Loretto drying projects.
Every active drying project in Loretto 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 Loretto 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 Loretto 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 Loretto 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 Loretto team is equipped and trained to handle.
Wall cavity drying in Loretto is standard procedure on every job where moisture mapping indicates wall system saturation.
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 Loretto 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 saturation after a water event in Loretto 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 Loretto structures.
Large-scale commercial drying in Loretto is project-managed from day one with zone-specific reading logs.
Mold prevention is not a separate service — it's built into every Loretto structural drying program we run.


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



"The most important thing about COS Water Damage Restoration's Loretto structural drying was that they explained the readings to me every single day. I understood what the numbers meant, what the target was, and how far we were from completion. By day six I was watching the moisture content readings in our wall framing drop from 28% to 11% and understood exactly what was happening and why. That level of transparency is what you need when your home is full of drying equipment for a week."
"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 Loretto 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."
