Since 2011, Alicia Brennan has led Back to Dry Restoration under The Haven Standard, building the company around the documentation gap that costs homeowners their insurance claims. We’ve restored 12,000+ homes, every one with a written price before work started and a photo record when the crew left. In Las Vegas, we regularly see mold take hold behind bathroom tile in Summerlin stucco homes, in attic spaces above Paradise ranch-style roofs after monsoon season, and in crawl spaces beneath older Spring Valley slabs where the desert’s extreme temperature swings create condensation the homeowner never notices until the smell spreads. Our technicians are background-checked, uniformed, and licensed; the license number is provided on every written scope. Live phone coverage answers 24 hours a day, 7 days a week with no voicemail trees.

What Our Mold Remediation Service Includes

Mold Inspection & Testing

A proper Mold Inspection & Testing locates the moisture source that feeds the colony, not just the visible growth. In Las Vegas, we find that 60% of mold calls start with a homeowner who has already tried bleach on drywall, which registers on a moisture meter as fresh water intrusion and can mask the actual spread. Our inspection includes room-by-room moisture readings with calibrated pin and pinless meters, thermal imaging to identify temperature differentials behind walls, and air sampling when the contamination is suspected but not visible. We deliver a written scope with photo documentation, material classifications by trade name, and the psychrometric data, which is the measurement of temperature and relative humidity that determines whether conditions will support regrowth.

Mold Removal

Mold Removal is the controlled demolition and disposal of contaminated porous materials: drywall, insulation, carpet pad, and structural wood that has exceeded 16% moisture content, the threshold where wood-decay fungi establish. We do not paint over mold. In Las Vegas homes built between 2015 and 2020, we regularly find removal is limited to a single bathroom or laundry closet because the original builder-grade exhaust fans were undersized for the square footage. Our crews establish negative air containment with HEPA filtration, seal HVAC returns to prevent cross-contamination, and document every square foot removed with before-and-after photography that becomes part of your file.

Black Mold Remediation

Stachybotrys chartarum, the species commonly called black mold, requires cellulose material that has remained wet for 72 hours or longer. In Las Vegas, this most often follows a slow plumbing leak inside a wall or a roof penetration that went unnoticed through the dry season until monsoon rains accelerated the damage. Remediation follows the same containment protocols as other species, with additional respiratory protection for technicians because of the mycotoxin potential. We test post-remediation air samples to confirm spore counts have returned to outdoor baseline levels before we remove containment. The written clearance report is included as a standard deliverable, never an upsell.

Air Quality Restoration

Air quality work addresses the spore load that has circulated through the HVAC system before the mold was discovered. In Las Vegas, where air conditioning runs eight months of the year, a contaminated return duct can distribute spores to every room in the house. We use HEPA air scrubbers with 99.97% efficiency at 0.3 microns, sized to achieve 6-12 air changes per hour in the affected zone. Duct cleaning, when indicated, is performed with negative pressure collection systems from Dri-Eaz and Phoenix, not rotary brushes that can dislodge debris into occupied spaces. The final air sample is collected with the HVAC running to confirm the system itself is not recontaminating the space.

Crawl Space Treatment

Crawl space mold in Las Vegas is often discovered during a home sale inspection, when the buyer’s inspector finds white or green growth on floor joists above the vapor barrier. Desert climate does not prevent crawl space mold; the temperature differential between 95-degree exterior air and 65-degree conditioned air below the floor creates condensation on the joist surfaces, particularly in Spring Valley and Enterprise homes with inadequate cross-ventilation. Our treatment includes removal of contaminated insulation, application of EPA-registered antimicrobial to structural members, and correction of the moisture driver, whether that’s a plumbing leak, improper grading, or missing vapor barrier. We document moisture readings at each joist bay and provide a drying log that shows progressive reduction in wood moisture content.

Moisture & Humidity Control

Controlling moisture is the only permanent solution to mold recurrence. After remediation, we install or recommend dehumidification systems sized to the specific cubic footage of the affected area, not the whole-house square footage that leads to over-drying and static electricity complaints. In Las Vegas, where outdoor relative humidity can drop to 8%, the problem is usually localized humidity pockets: a master bathroom without adequate exhaust, a north-facing wall with poor insulation, a water heater closet with no ventilation. We use vapor pressure differential measurements, the difference in moisture drive between two sides of a material, to identify where moisture is migrating and stop it at the source. The written scope includes our humidity control recommendations with specific equipment models and capacity ratings.

Brands We Service for Mold Remediation

Our equipment fleet includes professional-grade drying and air filtration systems from Dri-Eaz, Phoenix, XPOWER, and B-Air, documented to IICRC, RIA, and IFA standards. We’ve deployed hundreds of Dri-Eaz dehumidifiers in Las Vegas crawl spaces and attics, and we stock OEM replacement filters and condensate pumps to maintain their rated capacity throughout a multi-day drying project. Phoenix systems are our standard for large-loss containment jobs in Paradise and Sunrise Manor, where whole-room negative pressure is required to protect unaffected areas of the home.

XPOWER and B-Air air movers complete our drying configurations, positioned according to calculated airflow patterns rather than convenience. Whether your project requires equipment from these manufacturers or any other make, we can source, deploy, and document performance to the standards your insurer expects. Every machine’s serial number and hourly runtime are logged in the daily drying record that accompanies your invoice.

Signs You Need Mold Remediation Right Now

• A persistent musty odor that intensifies when the HVAC runs. This indicates active mold growth inside the duct system or near a return air pathway. In Las Vegas, where residents keep windows closed for months, the smell becomes background noise until a visitor comments. The odor is caused by microbial volatile organic compounds, and its presence means the colony is actively metabolizing, not dormant.
• Visible discoloration on walls, ceilings, or baseboards that returns after cleaning. Surface mold on non-porous materials can sometimes be wiped away, but recurrence within 48 hours means the growth extends into the substrate. We regularly find this pattern in Centennial Hills homes where bathroom exhaust fans vent into attic spaces rather than through the roof.
• Recent water damage that was dried without professional monitoring. A homeowner with a wet-dry vacuum and box fans can remove standing water while leaving wall cavities at 80% relative humidity, ideal conditions for hidden mold. Our moisture meters find these pockets in Aliante and Summerlin South homes months after the original leak was “handled.”
• Respiratory symptoms that improve when you leave the house. Not all mold-related health effects present as dramatic reactions; chronic sinus congestion, headaches, or fatigue that resolves during a weekend away from home is a documented pattern. We do not diagnose health conditions, but we do test air and surface samples when occupants report this correlation.
• Peeling paint or warping drywall in a room with no known leak. These are moisture signatures, and moisture is the prerequisite for mold. In Winchester and North Las Vegas homes, we trace these symptoms to slab condensation, irrigation line breaches, or failed window flashing that the homeowner had no reason to suspect.

Our Mold Remediation Process - Step by Step

1. 1
   Containment and negative air establishment. We seal the affected area with 6-mil polyethylene sheeting and create negative pressure using HEPA-filtered air scrubbers. This prevents spore migration during demolition. In Las Vegas, we often contain individual rooms in open-concept homes where the great room connects kitchen, dining, and living areas, requiring creative barrier placement to maintain the pressure differential.
2. 2
   Removal of contaminated materials. Porous materials that have supported mold growth are cut out and bagged within the containment. Non-porous surfaces are HEPA-vacuumed and treated with antimicrobial. We document every material classification and square footage on a written inventory that becomes part of your file. The written price for replacement materials, if reconstruction is needed, is provided before any rebuild work begins, per Haven Standard, Clause 1.
3. 3
   HEPA vacuuming and antimicrobial application. All surfaces within the containment receive sequential HEPA vacuuming and application of EPA-registered antimicrobial solution. We do not use bleach on structural materials; it damages wood fibers and leaves a water residue that can support new growth. The product we apply is rated for the specific material class: wood, concrete, or gypsum board.
4. 4
   Drying to established moisture content targets. Using Dri-Eaz and Phoenix dehumidification systems, we reduce wood moisture content below 14% and relative humidity below 60%. Daily moisture logs record readings at each affected location, with the technician’s initials and the equipment serial number. This documentation is what turns a restoration invoice into a claim an insurer will pay without a fight.
5. 5
   Post-remediation verification and clearance. We conduct visual inspection, moisture measurement, and air sampling before removing containment. The clearance criteria are specified in the written scope: typically, no visible mold, moisture content within 2% of unaffected control samples, and air spore counts at or below outdoor baseline. The signed clearance report and photo record are delivered as standard, never as an upsell.
