Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Etna 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 Etna team brings to every structural drying project that ensures complete, documented results.
Low-grain refrigerant (LGR) dehumidifiers operate more efficiently in the low-humidity conditions created by an active drying program than conventional dehumidifiers — achieving lower dewpoint conditions that accelerate evaporation from structural materials. Our Etna structural drying crews deploy properly sized LGR equipment based on the specific volume and material profile of your affected assemblies. Equipment sizing is calculated, not estimated.
Every active drying project in Etna 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 Etna 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 Etna 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.
Insurance-formatted drying documentation means faster settlement and fewer adjuster callbacks.
Here are the specific drying scenarios and assembly types our Etna team is equipped and trained to handle.
Wall cavity drying in Etna is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor and hardwood drying in Etna is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Etna 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 Etna structures.
Large-scale commercial drying in Etna is project-managed from day one with zone-specific reading logs.
Mold prevention is not a separate service — it's built into every Etna structural drying program we run.


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.
Daily readings, daily reporting, daily equipment adjustment if needed — documented throughout.
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 Etna 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."
