Mold Inspection
Our comprehensive mold inspections identify moisture sources and potential mold growth through systematic wall testing and visual analysis. Using invasive moisture meters, we detect hidden leaks in walls, under sinks, and around plumbing fixtures. The inspection covers both interior and exterior conditions conducive to mold development, providing a detailed assessment of structural vulnerabilities.
Air Sampling
Air sampling determines mold spore types and concentrations by comparing indoor and outdoor samples. We collect minimum two samples to establish baseline levels, identifying abnormal mold presence. Laboratory analysis provides quantitative data on airborne mold, helping determine remediation needs while following scientific protocols for accurate environmental assessment.
Surface Sampling
Surface sampling identifies mold species on visible growth areas through direct collection methods. While showing spore types present, this test complements air sampling by indicating potential contamination sources. Results help differentiate between normal environmental mold and problematic growth requiring professional remediation services.
Crawlspace Inspection
Specialized crawlspace inspections examine moisture levels and mold growth in hard-to-reach foundation areas. Our technicians identify ventilation issues, water intrusion points, and hidden contamination. This critical assessment prevents structural damage and indoor air quality problems originating from subfloor environments, requiring specific expertise and safety protocols.
Moisture Testing
Moisture testing measures wall content levels using calibrated meters to detect hidden water damage. We check every two feet at wall bases to identify elevated moisture above 15% thresholds. This proactive approach prevents mold development by locating and addressing moisture sources before visible growth occurs, crucial for early intervention.

Questions
What does a mold inspection involve?
Our inspection includes moisture testing, visual assessment of water damage, and air sampling when needed. Technicians check walls, plumbing fixtures, and exterior conditions to identify mold growth factors.
How long does mold testing take?
Initial inspection takes about an hour for standard homes. Laboratory results require 3-4 business days, with rush options available for faster turnaround.
What are common mold symptoms?
Exposure can cause respiratory issues, skin irritation, headaches, and allergic reactions. Symptoms vary based on mold type, concentration, and individual sensitivity levels.
Can I do mold testing myself?
Professional testing is recommended for accurate results. DIY kits lack proper analysis and interpretation by certified experts, potentially missing hazardous mold types.
How much does mold inspection cost?
Base inspection starts at $250 in Los Angeles. Additional fees apply for air sampling ($125/sample) and crawlspace access ($100). Travel fees may apply outside service areas.
What happens if mold is found?
We provide detailed remediation recommendations based on test results. While we don't perform remediation, our reports guide qualified professionals in addressing identified issues effectively.
