Commercial Ductwork Sealing and Related Services

OECM’s Commercial Ductwork Sealing and Related Services agreements provide access to a range of ductwork sealing and related services suitable for various buildings including schools, colleges, universities, municipal buildings, and more.

This agreement is the result of a procurement project initiated to support School Boards as part of the COVID-19 Resiliency Infrastructure Stream (CVRIS) Support Initiative for education-related projects that protect the health and well-being of students, staff, and children. As such, there may be significant demand from School Board customers in 2021, however, the resulting agreement has a term that extends beyond 2021 and is available to support all OECM customers.
