Visible water is only the first part of a water damage problem. Once the puddles are gone, moisture can still remain inside drywall, insulation, subfloors, and framing.
The water you can see and feel is only part of what a restoration professional deals with after a flood, pipe burst, or appliance leak. The water that causes the most lasting damage is the water you can’t see: moisture absorbed deep into drywall, insulation, subfloor sheathing, wall cavities, and structural lumber. When that hidden moisture isn’t extracted and monitored correctly, the result can be mold growth, wood rot, compromised structural integrity, and indoor air quality problems that persist long after the visible damage is repaired.
Professional structural drying is not guesswork. It is a documented, measurable science – and in Denver’s climate, with its unique combination of high altitude, low relative humidity, and dramatic weather swings, getting it right requires real expertise.
What Is Structural Drying?
Structural drying refers to the process of removing moisture from the materials that make up a building – its framing, walls, floors, and ceilings – after those materials have been saturated by water. It is distinct from simply removing standing water (extraction) or replacing wet materials (demolition).
The goal is “restorative drying”: returning materials to their normal, pre-loss moisture content without tearing them out unnecessarily. This approach saves money, reduces disruption, and – when done correctly – produces a result that is just as effective as full replacement.
The IICRC Applied Structural Drying (ASD) certification is the industry’s benchmark credential for technicians performing this work. ASD-certified technicians are trained in the effective, efficient, and timely drying of water-damaged structures and contents within a restorative drying environment, with a focus on protecting the health and safety of both workers and building occupants.
The Foundation: Psychrometrics
Structural drying is built on psychrometrics – the science of the thermodynamic properties of moist air and how moisture moves between air and materials.
Here’s the basic principle: water in a wet material (like drywall or hardwood) will evaporate into the surrounding air if that air has a low enough relative humidity and sufficient temperature. Once evaporated, that moisture must be captured and removed from the structure by a dehumidifier – otherwise, it will re-absorb into other materials or raise indoor humidity to levels that slow drying or promote mold growth.
Professional technicians use psychrometric charts and moisture calculations to determine:
- The current moisture content of affected materials
- The drying capacity of the air in the affected space
- How much dehumidification is needed
- How long drying should take under current conditions
- Whether conditions are trending toward or away from target drying goals
This is why a proper drying job isn’t simply placing equipment and walking away – it requires daily monitoring and adjustment.
The Equipment Professionals Use
Moisture Meters and Thermal Imaging
The first step in structural drying is mapping – identifying exactly where moisture is present and at what levels. Technicians use penetrating and non-penetrating moisture meters to test drywall, wood framing, and flooring. Thermal imaging cameras detect temperature differentials that reveal moisture hidden inside walls without invasive testing.
This moisture map becomes the baseline against which all drying progress is measured.
Air Movers
High-velocity air movers, sometimes called air blowers, create rapid airflow across wet surfaces. This accelerates evaporation by constantly replacing the saturated air near a wet surface with drier air from further away. LGR units are a type of dehumidifier, not air movers. The placement of air movers is strategic – technicians calculate the number and positioning needed based on the size of the affected area and the materials involved.
Low-Grain Refrigerant (LGR) Dehumidifiers
LGR dehumidifiers remove the moisture that air movers evaporate from materials. These commercial-grade units are substantially more powerful than the dehumidifiers available at a hardware store. A professional restoration dehumidifier can remove 70 to 200 pints of water per day, depending on the unit and conditions.
Desiccant Dehumidifiers
In Denver’s colder months or in particularly cold spaces (crawl spaces, garages), refrigerant-based dehumidifiers lose efficiency. Desiccant dehumidifiers use silica gel or similar materials to absorb moisture from the air without relying on temperature differentials. They are often used in cold-weather structural drying jobs along the Front Range.
Injectidry Systems and Structural Cavity Drying
When water has infiltrated wall cavities, insulation, or the space beneath hardwood flooring, surface air movers alone cannot dry those areas effectively. Technicians use specialized equipment like injectidry systems that insert tubes or panels directly into wall cavities and create controlled airflow through otherwise inaccessible spaces – without requiring extensive demolition.
The Role of IICRC Standards
The ANSI/IICRC S500 Standard for Professional Water Damage Restoration sets the procedural baseline that qualified restoration companies follow. This standard covers:
- Psychrometry and drying technology
- Building and material science
- Equipment, instruments, and tools
- Safety and health during restoration
- Documentation and risk management
The IICRC Water Restoration Technician (WRT) certification gives technicians the foundational knowledge to understand water damage, its effects, and the techniques needed for effective structural drying. The ASD certification builds on that with applied, hands-on skills for setting up and managing drying systems.
When you hire an IICRC-certified restoration company, you’re hiring professionals whose work is grounded in a nationally recognized standard – not improvised methods.
The 24- to 48-Hour Window: Why Speed Matters
The EPA is unambiguous on this point: water-damaged areas and items should be dried within 24 to 48 hours to prevent mold growth. The CDC/NIOSH echoes this, noting that drying wetted materials within 48 hours – or removing them – is a cornerstone of appropriate remediation.
Mold spores are present in virtually every indoor environment. They need only three things to begin growing: a surface, moisture, and time. In Denver, where indoor humidity can swing significantly with seasonal changes, a wet wall cavity can become a mold habitat within two days if not addressed.
Once mold establishes in a wall cavity, the scope of remediation expands significantly – typically requiring containment, HEPA filtration, material removal, and air quality testing. The cost and disruption of mold remediation far exceeds the cost of prompt, professional drying.
This is why Anatom Restoration responds 24/7 to water damage emergencies throughout Denver, Aurora, Centennial, and Colorado Springs. The faster structural drying begins, the more material can be saved – and the more likely you are to avoid a secondary mold problem.
Denver’s Climate and Structural Drying
Denver’s geography creates some unique drying dynamics.
High altitude: Denver sits at approximately 5,280 feet above sea level. Lower atmospheric pressure at altitude means water evaporates at a lower temperature, which can actually accelerate evaporation from wet materials under the right conditions. Technicians familiar with Denver’s altitude calibrate their psychrometric calculations accordingly.
Low ambient humidity: Denver’s average relative humidity is one of the lowest among major U.S. cities. In spring and summer, this means the ambient air naturally supports faster drying. However, it also means that homeowners may underestimate the severity of hidden moisture because the surface dries quickly while interior materials remain wet.
Seasonal temperature swings: Denver’s winter temperatures complicate structural drying by reducing dehumidifier efficiency. After storm damage or winter pipe bursts, technicians may need to deploy desiccant dehumidifiers or temporary heat to maintain effective drying conditions.
What Happens When Drying Is Done Wrong
Inadequate drying – whether from DIY attempts or underpowered professional work – leads to predictable problems:
- Mold growth inside walls, under flooring, or in crawl spaces
- Wood rot in structural framing and subfloor sheathing
- Warping and buckling of hardwood floors and cabinets
- Adhesion failure in flooring materials
- Persistent musty odors from microbial activity
- Paint and drywall failures from ongoing moisture movement
- Compromised structural integrity in severe cases
Many of these problems don’t appear immediately. They surface weeks or months after the original damage event – often after a homeowner believes the issue is fully resolved. By then, repair costs are significantly higher than they would have been with prompt professional drying.
How Anatom Restoration Approaches Structural Drying
When Anatom Restoration responds to a water damage call in Denver, the process follows a consistent, standards-based approach:
- Extraction – Remove standing water with truck-mounted or portable extractors
- Moisture mapping – Use meters and thermal imaging to document baseline moisture levels in all affected materials
- Equipment setup – Place air movers, dehumidifiers, and specialty drying equipment based on calculated drying needs
- Daily monitoring – Return each day to measure moisture levels, adjust equipment, and document progress
- Documentation – Maintain a complete drying log that includes daily readings, equipment placement, and psychrometric data
- Final assessment – Confirm that all materials have reached target moisture levels before equipment is removed and reconstruction begins
This process is not rushed, and it is not finished until the numbers confirm it.
