Why Choose Us

What Separates Professional Structural Drying in Des Moines 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

Undersized or generic dehumidification is the most common technical failure in Des Moines drying projects.

📈

Daily Psychrometric Records

Every active drying project in Des Moines 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 Des Moines properties originates. It's where we focus.

📋

Insurance-Formatted Reports

COS Water Damage Restoration's Des Moines 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.

Services

Our Des Moines Structural Drying Scope

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

🏠

Wall Framing & Drywall Cavity Drying

Wall cavity drying in Des Moines is standard procedure on every job where moisture mapping indicates wall system saturation.

🧱

Subfloor & Hardwood Assembly Drying

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

🔮

Crawlspace & Below-Grade Drying

Crawlspace drying in Des Moines properties is complicated by limited access, typically poor natural ventilation, and the presence of vapor barriers that may trap moisture against wood framing. Our Des Moines 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

Ceiling assembly drying is one of the more technically demanding aspects of water damage restoration in Des Moines structures.

🏛

Commercial & Multi-Room Drying Programs

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

🔏

Mold Prevention Monitoring

Every active structural drying program in Des Moines is also a mold prevention program — because the conditions that support mold growth (elevated moisture content in organic materials and elevated relative humidity in the air space) are exactly the conditions a drying program is designed to eliminate. Our daily reading sessions include assessment of the ambient RH and temperature conditions in each drying zone against the threshold conditions that support mold colonization. If readings suggest an elevated mold risk — particularly in projects where extraction was delayed — we address it proactively with targeted antimicrobial treatment during the active drying program.

Our Process

How Structural Drying Works in Des Moines

Moisture Mapping

Equipment before mapping is guesswork. Mapping before equipment is science.

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 Des Moines 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

Completion is confirmed by instruments and documented in writing. No visual estimates.

Reviews

Des Moines 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."

O. Delacroix

★★★★★

"We had a particularly complex drying project across three floors of a Des Moines 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 Des Moines

How long does Structural Drying take in Des Moines?

Structural drying timelines in Des Moines 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 Des Moines 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 Des Moines?

Equilibrium moisture content (EMC) targets depend on the material being dried and the ambient conditions in Des Moines. 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 Des Moines 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 Des Moines?

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 Des Moines team evaluates each wall section individually and documents the decision in the written scope.

What are psychrometric readings and why do they matter for Des Moines 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 Des Moines?

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 Des Moines 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 Des Moines home while structural drying equipment is running?

Yes — in most cases, you can remain in your Des Moines 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 Des Moines 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.
