Most water damage events look dry long before the structural assemblies actually are. A room that smells fine and feels dry to the touch may have framing at 25-30% moisture content — well above the 6-12% target range required for true structural drying. COS Water Damage Restoration's Streeter structural drying program is driven by daily psychrometric readings, not visual judgment.
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 Streeter team brings to every structural drying project that ensures complete, documented results.
Undersized or generic dehumidification is the most common technical failure in Streeter drying projects.
Every active drying project in Streeter 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 Streeter properties originates. It's where we focus.
Insurance-formatted drying documentation means faster settlement and fewer adjuster callbacks.
COS Water Damage Restoration's Streeter 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 Streeter is standard procedure on every job where moisture mapping indicates wall system saturation.
Subfloor and hardwood drying in Streeter is species-specific and requires daily monitoring of cupping and moisture gradient.
Crawlspace saturation after a water event in Streeter 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 Streeter property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Streeter 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 Streeter is project-managed from day one with zone-specific reading logs.
Mold prevention is not a separate service — it's built into every Streeter structural drying program we run.


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



"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 Streeter 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."
