Knight Environmental Consulting in Encinitas is a veteran-owned and women-owned environmental testing firm established in 1995, specializing in mold inspection, air-quality sampling, and hazardous-materials assessment from its Second Street office. Indoor air-quality investigations deploy spore-trap cassettes and direct-examination swab sampling to identify Stachybotrys, Aspergillus, and Penicillium contamination — findings that inform the post-remediation renovation scopes at design firms such as JY Design Interiors. Asbestos and lead-paint surveys follow EPA AHERA and HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards protocols for pre-renovation and pre-demolition compliance in residential and commercial structures. Environmental abatement oversight includes clearance testing and chain-of-custody lab submissions coordinated with the property-condition reporting at McCaffery Reserve Consulting. Highest-tier assessments involve NIOSH Method 7400 phase-contrast microscopy fiber counts for airborne asbestos quantification and EPA Method TO-15 volatile organic compound canister sampling for industrial hygiene compliance.
