Our Specialized Capabilities

Complete Building Biology Diagnostics

Evaluation of high-frequency radiation (5G towers, Wi-Fi, radar) and low-frequency electrical fields from power lines and building wiring in sleeping quarters.

  • High-frequency spectrum analysis
  • Magnetic & electric field mapping
  • Shielding strategy solutions

Chemicals & VOC Toxins

Testing for Volatile Organic Compounds (VOCs), formaldehyde, solvents, synthetic finishes, and pesticides common in newly renovated historic properties.

  • Formaldehyde & paint toxin checks
  • Particulate matter (PM2.5 / PM10)
  • Ventilation rate optimization

Pre-Purchase Property Audit

Crucial due diligence for international buyers and real estate investors in Lisbon, Cascais, and Sintra before making binding property offers.
