Featured Testimonial

“Tozour SMART Services is critical to managing our building, especially during the coronavirus pandemic. Remote supervision means we have peace of mind 24/7, and we appreciate Tozour because most issues are resolved remotely. When onsite service is needed, a technician is dispatched quickly, which is just as important as remote supervision. Tozour is a one-stop-shop and an extension of our Atkins team.”

Indoor Air Quality Assessments

As you welcome back employees, tenants and customers into your building Indoor Air Quality (IAQ) will be more important than ever before.

Great indoor air quality will help you:

  • Restore the confidence of building tenants to return to your facilities with more comfortable and cleaner air;
  • Support resilience against future issues by installing trusted solutions; and
  • Contribute to your building’s overall sustainability with targeted investments that generate results.

These goals can be achieved with a proper IAQ assessment of your buildings.
