Why Choose Us

What Separates Professional Structural Drying in Saint Francis from Surface Drying

The difference between structural drying done right and structural drying done fast is what ends up in your walls three months later.

🌊

LGR Dehumidification

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 Saint Francis 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.

📈

Daily Psychrometric Records

Every active drying project in Saint Francis 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

Wall cavity drying is where most post-loss mold in Saint Francis properties originates. It's where we focus.

📋

Insurance-Formatted Reports

COS Water Damage Restoration's Saint Francis 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.

Our Saint Francis Structural Drying Scope

Here are the specific drying scenarios and assembly types our Saint Francis team is equipped and trained to handle.

🏠

Wall Framing & Drywall Cavity Drying

The most common drying failure in Saint Francis water damage projects is a wall framing cavity left with elevated moisture content after surface materials are dry. Our Saint Francis team uses calibrated cavity access — typically 1-inch drill holes at the base of the wall framing cavity — to introduce directed airflow from high-velocity air movers into the stud bay, paired with LGR dehumidification to extract the evaporated moisture. Moisture readings at framing sensor points confirm completion. Access ports are patched and filled after the program completes, typically leaving no visible trace of the access procedure.

🧱

Subfloor & Hardwood Assembly Drying

Subfloor and hardwood drying in Saint Francis is species-specific and requires daily monitoring of cupping and moisture gradient.

🔮

Crawlspace & Below-Grade Drying

Crawlspace drying in Saint Francis properties is complicated by limited access, typically poor natural ventilation, and the presence of vapor barriers that may trap moisture against wood framing. Our Saint Francis below-grade drying team is equipped with compact high-velocity air movers that fit through standard crawlspace access hatches, portable LGR units configured for below-grade operation, and moisture meters suitable for sub-surface readings at joist and beam locations. Vapor barrier condition is evaluated and re-secured after drying if disturbed during the process.

💨

Ceiling & Overhead Assembly Drying

Water that migrates down from an upper floor or a roof intrusion in a Saint Francis property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Saint Francis 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.

🏛

Commercial & Multi-Room Drying Programs

Large-scale commercial drying in Saint Francis is project-managed from day one with zone-specific reading logs.

🔏

Mold Prevention Monitoring

Mold prevention is not a separate service — it's built into every Saint Francis structural drying program we run.

Our Process

How Structural Drying Works in Saint Francis

Moisture Mapping

Before one piece of drying equipment is placed, our Saint Francis 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.

Engineered Equipment Staging

Equipment placement is engineered based on the moisture map and assembly data — not placed by habit.

Daily Psychrometric Monitoring

Every calendar day, our Saint Francis 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.

Confirmed Completion

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.

Reviews

Saint Francis Customers on Our Structural Drying Service

★★★★★

"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."

★★★★★

"The thermal imaging session at the beginning was what showed us the water had migrated into a wall cavity adjacent to the flooded room that we never would have found otherwise. COS Water Damage Restoration set up wall cavity drying for that section specifically, and the final readings confirmed it came out completely dry alongside everything else. That's the kind of detail that prevents the mold problem three months later."

★★★★★

"We had a particularly complex drying project across three floors of a Saint Francis 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."

FAQs

Common Questions — Structural Drying in Saint Francis

How long does Structural Drying take in Saint Francis?

Structural drying timelines in Saint Francis vary based on material type, saturation level, ambient conditions, and the assembly configuration of the affected area. A well-managed drying program using properly sized LGR equipment and daily monitoring typically runs 3-7 days for standard wall and floor assemblies, 5-10 days for wall cavity and subfloor assemblies with significant saturation, and longer for dense structural assemblies such as hardwood over concrete or multi-layer floor systems. Your Saint Francis project manager provides a realistic range at the initial moisture mapping session and updates it daily based on the actual readings.

What is the target moisture content for structural drying in Saint Francis?

Equilibrium moisture content (EMC) targets depend on the material being dried and the ambient conditions in Saint Francis. For softwood framing (the most common structural material), industry standard targets are typically 6-12% moisture content. For hardwood flooring, targets adjust based on species and acclimation moisture content for the ambient conditions in your property. Drywall targets are measured separately by core readings. Your Saint Francis drying crew documents the target range for each material in the project file and confirms completion when all readings fall within range.

Can drywall be dried in place during Structural Drying in Saint Francis?

Standard gypsum drywall can sometimes be dried in place if: the water source was clean (Category 1), the saturation period was short (less than 24-48 hours), the drywall face paper is intact and not delaminating, and cavity moisture readings from the wall behind indicate manageable saturation levels. When these conditions are not met — particularly with Category 2/3 events or extended saturation — removing the drywall and drying the framing directly is both more effective and safer from a mold risk standpoint. Our Saint Francis team evaluates each wall section individually and documents the decision in the written scope.

What are psychrometric readings and why do they matter for Saint Francis drying?

Psychrometrics is the study of air moisture relationships. In a drying program, psychrometric readings measure the temperature and relative humidity of the air in each drying zone, from which we calculate the specific humidity (grains of water per pound of dry air) and the dewpoint temperature. These calculations tell us how much moisture the air is holding relative to its capacity, and how efficiently the LGR dehumidification equipment is removing moisture from the air space. Combined with direct moisture content readings in structural materials at fixed sensor points, psychrometric data gives us a complete picture of the drying system's performance — and tells us when the drying program is genuinely complete, not just visually complete.

Will COS Water Damage Restoration provide drying documentation for my insurance claim in Saint Francis?

Yes — daily psychrometric logs, moisture content readings at sensor point locations mapped to a floor plan, equipment placement and settings records, and a written drying completion report are all generated by our Saint Francis team and provided for your insurance claim file. Our drying documentation is formatted to match what insurance carriers request for the drying phase of water damage claims, which reduces the likelihood of a documentation-based supplement dispute.

Can I stay in my Saint Francis home while structural drying equipment is running?

Yes — in most cases, you can remain in your Saint Francis home while structural drying equipment runs. The equipment creates noise and slightly elevated temperatures in the affected areas, and the ambient humidity in the drying zones drops significantly during the program. Our Saint Francis team will walk you through what to expect during the active drying program: which areas will have equipment, what the noise and temperature conditions will be like, and what household activities (opening windows to outside humidity, running a home humidifier) should be avoided during the drying cycle.
