More testing contracts for indoor air quality testing labs

Indoor air quality testing is bought by people responsible for a building full of other people. A facilities director answering a staff complaint, a school operations lead under a parent's pressure, or a property manager defending a lease renewal all need defensible sampling and a clean lab report, and they award those contracts to a lab they trust by name. Those buyers do not search a directory at random, they sign annual monitoring agreements and call the same lab for every new concern. Find the operations leads, the facility managers and the school administrators in your region, reach them with a message about the building they actually run, and turn single tests into standing monitoring contracts, free to start.

We were waiting on referrals for IAQ work. LeadStal let me target facility directors and school operations leads directly, and we signed three annual monitoring contracts in our first quarter using it.
