What to expect from a commercial request

Understand the service path, the findings and the proposed work before deciding what to approve.

The initial on-site visit costs $150. Commercial service and project work are quoted separately based on the equipment, access and applicable requirements.

  1. Share the request

    Tell NRB about the property, equipment and service or project you have in mind. Share the details already available.

  2. Confirm the service fit

    NRB reviews the known equipment, access and requirements, clarifies missing information and determines the appropriate next step.

  3. Review the equipment on site

    When an on-site visit is needed, NRB reviews the equipment and relevant site conditions. For an existing system issue, the visit includes a complete review and diagnosis; for a planned project, NRB reviews the equipment needs and site conditions.

  4. Review the findings and proposed work

    NRB explains what was found, the recommended scope and the applicable cost. Additional work proceeds only after you approve it.

A request may need additional information, a site review or clarification of building, permit or other-trade requirements before the scope can be confirmed.

What helps us review your request

You can tell us about your property, equipment, the work you need and any project requirements. You don’t need to have all the details before contacting NRB.
