Why Choose Us

What Separates Professional Structural Drying in Sandstone 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 Sandstone drying projects.

📈

Daily Psychrometric Records

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

📋

Insurance-Formatted Reports

Insurance-formatted drying documentation means faster settlement and fewer adjuster callbacks.

Services

Our Sandstone Structural Drying Scope

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

🏠

Wall Framing & Drywall Cavity Drying

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

🧱

Subfloor & Hardwood Assembly Drying

Subfloor assemblies — OSB or plywood sheathing over floor joists — and hardwood flooring systems require targeted drying approaches because of their density and their tendency to cup, buckle, or swell when dried too aggressively or left wet too long. Our Sandstone drying crew evaluates hardwood flooring species and moisture content before recommending drying-in-place versus removal, and when drying in place is appropriate, we use floor drying mats that direct conditioned air against the top face of the hardwood under controlled pressure — accelerating evaporation while minimizing the differential drying stress that causes cupping.

🔮

Crawlspace & Below-Grade Drying

Crawlspace drying in Sandstone properties is complicated by limited access, typically poor natural ventilation, and the presence of vapor barriers that may trap moisture against wood framing. Our Sandstone 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 Sandstone property saturates ceiling drywall and the framing above it — areas that are impossible to reach with standard floor-level equipment. Our Sandstone 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 Sandstone 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 Sandstone structural drying program we run.

Our Process

How Structural Drying Works in Sandstone

Moisture Mapping

Before one piece of drying equipment is placed, our Sandstone 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

Based on the moisture map, our Sandstone 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 Psychrometric Monitoring

Daily readings, daily reporting, daily equipment adjustment if needed — documented throughout.

Confirmed Completion

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

Reviews

Sandstone 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."

★★★★★

"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."

O. Delacroix

Verified Sandstone, MN Customer

★★★★★

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

How long does Structural Drying take in Sandstone?

Structural drying timelines in Sandstone 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 Sandstone 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 Sandstone?

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

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

What are psychrometric readings and why do they matter for Sandstone 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 Sandstone?

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 Sandstone 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 Sandstone home while structural drying equipment is running?

Yes — in most cases, you can remain in your Sandstone 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 Sandstone 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.
