Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Princeton 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.
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 Princeton 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 Princeton 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 Princeton properties originates. It's where we focus.
COS Water Damage Restoration's Princeton 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 Princeton team is equipped and trained to handle.
Wall cavity drying in Princeton is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor and hardwood drying in Princeton is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Princeton 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 Princeton property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Princeton 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-scale commercial drying in Princeton is project-managed from day one with zone-specific reading logs.
Mold prevention is not a separate service — it's built into every Princeton structural drying program we run.


Equipment before mapping is guesswork. Mapping before equipment is science.
Based on the moisture map, our Princeton 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.
Daily readings, daily reporting, daily equipment adjustment if needed — documented throughout.
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 Princeton 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 had a particularly complex drying project across three floors of a Princeton 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."

Structural drying that's done when it looks done leads to mold. Structural drying that's done when the readings confirm it leads to a genuinely recovered property. Call +1-844-499-0972 and our Princeton drying crew brings the instruments and the protocol.
