When a moisture or mold problem is suspected, a qualified professional should always be consulted.
💧 Moisture Control & Crawlspace Equipment
Moisture control is generally considered one of the most important factors in mold prevention. The products below represent what is generally used by IAQ professionals and remediation contractors when addressing crawlspace and basement moisture issues.
Alorair Crawlspace Dehumidifier
Commercial-grade dehumidifiers are what is generally used in professional crawlspace moisture remediation and encapsulation programs. Alorair units are widely used in the IAQ and restoration industry for their capacity, durability, and efficiency ratings.
Alorair — The Dry Air Drying Equipment
Professional drying equipment is what is generally recommended during water damage drying protocols and post-remediation drying programs. Proper drying equipment is considered a standard part of any mold prevention and remediation workflow.
Zoeller Sump Pumps
Zoeller is widely used in professional sump pump applications in crawlspaces and basements. Submersible and pedestal models are generally recommended for continuous water removal in high-moisture environments where mold risk is elevated.
Sump Pump Alarms
High-water alarms are what is generally recommended as a backup monitoring system for sump pump failure detection. Audible and connected alarm systems are generally used to alert homeowners and property managers before water accumulation creates a mold-conducive environment.
Condensate Pumps
Condensate pumps are what is generally used to remove water produced by HVAC systems, dehumidifiers, and air handlers in crawlspaces and mechanical rooms. Proper condensate management is generally considered a standard part of any IAQ and moisture control program.
🔍 Mold Testing & Detection Tools
Testing and detection tools support documentation rather than assumptions. The tools below are what is generally used by IAQ professionals and informed homeowners when assessing a building for mold, moisture, and air quality concerns.
DIY Mold Test Kits
Generally used for initial surface and air screening for mold presence in residential and commercial buildings.
Digital Moisture Meters
Identifying elevated moisture in building materials — the primary indicator of mold risk. Generally the most-used tool in any mold inspection.
Thermal Hygrometers
Monitoring temperature and relative humidity — the two primary drivers of mold growth. Generally recommended for ongoing IAQ monitoring.
Borescope / Inspection Camera
Visual inspection of wall cavities, crawlspaces, and hard-to-reach areas. Generally used when surface indicators point to hidden moisture or mold.
Radon Test Kits
Short and long-term radon screening generally recommended as part of a comprehensive IAQ assessment in residential buildings.
VOC / Air Quality Monitors
Detecting volatile organic compounds and multi-parameter air quality readings. Generally used as part of a comprehensive IAQ evaluation.
🛡️ Remediation Equipment & Supplies
The products below represent what is generally used by professionals during mold remediation projects. Scope and severity should always be assessed by a qualified professional before any remediation work begins.
N95 / P100 Respirators
Respiratory protection is generally recommended during mold inspection or remediation work. Level of protection should match the scope of the project.
Tyvek Disposable Coveralls
Preventing cross-contamination during remediation. Disposable coveralls are generally used as standard PPE to protect both the worker and the surrounding environment.
HEPA Air Scrubbers
Establishing negative air pressure and capturing airborne spores during active remediation. Generally used as a core piece of equipment on any professional remediation project.
HEPA Vacuums
Spore cleanup on hard surfaces prior to antimicrobial treatment. Generally recommended before any surface treatment is applied during a remediation protocol.
EPA-Registered Antimicrobial Sprays
Treatment of affected surfaces as part of a mold remediation protocol. EPA-registered products are what is generally recommended for use in occupied and commercial buildings.
6-Mil Poly Sheeting
Construction of containment barriers to prevent spore migration during remediation. 6-mil poly sheeting is what is generally used as the standard material for containment on remediation projects.
🌿 Prevention & Long-Term Indoor Air Quality
Mold prevention is not a one-time fix — it is an ongoing practice. The products below are what is generally recommended by IAQ professionals for maintaining healthy indoor air quality, controlling humidity, and reducing the conditions that allow mold to return.
Alorair Crawlspace Dehumidifier
Commercial-grade dehumidification is generally used in crawlspace moisture prevention programs.
Alorair Dry Air Equipment
Whole-structure moisture management and professional drying programs. Generally recommended for post-remediation drying and ongoing moisture control in larger structures.
HEPA Air Purifiers
Ongoing reduction of airborne mold spores, particulates, and allergens in occupied spaces. Generally recommended as a first step in improving IAQ in affected areas.
MERV-13 HVAC Filters
Whole-home air filtration upgrade. MERV-13 filters are generally recommended over standard 1-inch filters for improved capture of mold spores and fine particulates.
Crawlspace Vapor Barriers
The foundational moisture control layer in any crawlspace encapsulation program. Polyethylene vapor barriers are generally used as the first line of defense against ground moisture intrusion.
Portable Dehumidifiers
Humidity control in basements, crawlspaces, and living areas. Portable units are generally recommended where a permanent installation is not yet in place.
CO2 / Multi-Parameter IAQ Monitors
Ongoing monitoring of CO2, humidity, VOCs, and particulates in occupied spaces. Multi-sensor monitors are generally used for continuous IAQ tracking in residential and commercial buildings.
ERV / HRV Ventilation Units
Balanced fresh air exchange in tight, energy-efficient buildings. ERV and HRV units are generally recommended when improving ventilation without sacrificing energy efficiency.
