Structural drying that finishes on a timeline, not when the instruments confirm it, leads to mold behind walls and the callbacks that follow. Our Grand Junction 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 Grand Junction 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 Grand Junction 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.
Documented daily readings are what separate a professional drying program from a rental dehumidifier in the corner.
Wall cavity drying is where most post-loss mold in Grand Junction properties originates. It's where we focus.
Insurance-formatted drying documentation means faster settlement and fewer adjuster callbacks.
COS Water Damage Restoration's Grand Junction 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.
Wall cavity drying in Grand Junction is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor and hardwood drying in Grand Junction is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Grand Junction 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 Grand Junction property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Grand Junction 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 Grand Junction is project-managed from day one with zone-specific reading logs.
Mold prevention is not a separate service — it's built into every Grand Junction structural drying program we run.


Before one piece of drying equipment is placed, our Grand Junction team completes a full moisture mapping session using FLIR thermal imaging and calibrated pin-type and non-penetrating meters. The map documents all affected assemblies, saturation levels, and the extent of moisture migration through the structure. Equipment placement and sizing are calculated from this map.
Equipment placement is engineered based on the moisture map and assembly data — not placed by habit.
Every calendar day, our Grand Junction 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 Grand Junction 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 Grand Junction 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."
